* Centers of excellence <strong>for</strong> brush rolls!


High quality raw materials, years of experience, modern manufacturing<br />

techniques, and careful workmanship. These are<br />

important criteria which ensure the consistently high quality<br />

of OSBORN products. Quality assurance accompanies all<br />

stages of production. It is fully integrated into the processes<br />

and certified in accordance with DIN EN ISO 9001-2000. This<br />

has made us the world’s #1 supplier in brush technology, but<br />

we are not satisfied with that. Constant innovation and product<br />

development are of central importance to us, both inhouse<br />

and in close cooperation with technology partners in<br />

Europe, Asia and North America. We seize the goal of making<br />

our range of services, and with it the products and processes<br />

of our customers, better, faster, safer, more reliable and more<br />

environmentally friendly.<br />

2.1<br />

Brush roll applications<br />

Degreasing, washing and cleaning<br />

The demands relating to the quality and the technical product<br />

characteristics of flat rolled steel in the <strong>for</strong>m of cold<br />

rolled steel, tin plated steel, electrical steel, galvanized strips<br />

or other refined surface materials are steadily rising. Along<br />

with increasing processing speeds, optimising the tempering,<br />

refinement or coating process of the upstream strip<br />

cleaning section also increases.<br />

comparison to conventional brush rollers. HDL ® sets new<br />

standards in the degreasing and cleaning of strip surfaces.<br />

Through the consistent development of quality, by looking<br />

at fill material, brush construction and fill density, we<br />

achieve significant improvements in terms of the brush lifetime<br />

/ cleaning per<strong>for</strong>mance. This results in reduced operating<br />

and maintenance costs <strong>for</strong> our customers.<br />

With the development and introduction of the HDL ® brush<br />

roller, OSBORN has found an answer to these demands, in<br />

OSBORN HDL ®<br />

<strong>Technology</strong><br />

OSBORN HDL ®<br />

- a new benchmark in strip cleaning<br />

Customers’ needs depend on the type and degree of soiling<br />

of the primary material as well as on the strip cleanliness<br />

required <strong>for</strong> the subsequent process step. While optimum<br />

degreasing and micro-cleaning may be achieved with nonabrasive<br />

multi-filaments, abrasive filaments are ideally suited<br />

<strong>for</strong> the removal of strongly adhesive rolling retentions from<br />

the previous rolling process.<br />

5<br />

OSBORN HDL ® brush rollers are there<strong>for</strong>e individually tailored<br />

to the relevant case in hand. At the same time, multi-filaments<br />

and special mono-filaments can be used with or without<br />

an abrasive load as single bristle or mixture filaments.


Besides brush rollers <strong>for</strong> degreasing and cleaning applications,<br />

OSBORN offers a series of other innovative products<br />

and solutions <strong>for</strong> cleaning sections of strip lines:<br />

• LOAD RUNNERS ® ensure a durable and maintenance-free<br />

function of roll exchange vehicles.<br />

• Temperature and alkaline resistant brush seals provide<br />

optimum splash protection on the strip inlet and outlet of<br />

individual machine elements.<br />

• Vacuum squeezing systems set new standards in the complete<br />

drying of strip edges. It is possible to replace the hot<br />

air dryer altogether, resulting in enormous energy savings.<br />

• In the modernisation of strip lines, it is possible, through the<br />

integration of optimised brush machines instead of the old<br />

line, to create additional space <strong>for</strong> further improvements to<br />

the line. This is achieved by the compact design as well as an<br />

improvement in cleaning efficiency.<br />

• NOVOTEX ® squeezing rollers complete the OSBORN strip<br />

cleaning range. Compared to conventional rubber or<br />

polyurethane rollers, these non-woven rolls offer a number<br />

of beneficial product characteristics, such as significantly<br />

better coefficients of friction, material compression or cut<br />

and wear resistance. This in turn ensures longer durability,<br />

improved squeezing results, prevention of aquaplaning<br />

and reduction of damage to the strip.<br />

2.2<br />

Brush roll applications<br />

Activation of strip surface<br />

The activation of the strip surface is an important task both<br />

in the production of rolled claddings as well as in the coating<br />

and/or finishing of strip steel, tinplate, electrical steel<br />

strip and other materials. In rolled cladding, the core and, if<br />

necessary, the overlay strips or plates have to be freed initially<br />

from oil, grease, dirt, carbon particles and oxides. This<br />

is done with the help of brush rollers in alkaline cleaning or<br />

acidic pickling processes.<br />

In the next process step, an activation of surfaces then takes<br />

place by generating a defined roughness using abrasive or<br />

wire brushes. A similar process also happens in continuous<br />

strip coating. In both cases, an optimal adhesion is guaranteed<br />

<strong>for</strong> the subsequent rolled cladding and/or organic or<br />

metallic coating through surface activation.<br />

OSBORN HDL ®<br />

- micro cleaning plus surface activation<br />

Here too, HDL ® rollers from OSBORN create an ideal combination<br />

of the different brush functions needed by our customers.<br />

The non-abrasive multi-filaments ensure optimum<br />

micro-cleaning as the abrasive filament mechanically intensifies<br />

its abrasive effect and at the same time generates the<br />

required surface activation. The grinding agent, grain size,<br />

face density and abrasive content are also individually adjusted<br />

to the respective individual application.<br />

OSBORN has devoted itself to this challenge <strong>for</strong> years. We<br />

have strategically maneuvered ourselves to be the premier<br />

producer of brush rollers through the development of innovative<br />

microfilaments and brush constructions as well as the<br />

preservation of high quality standards.<br />

In steel sheet coating, the brush roller has long been promoted<br />

as an absolute high-per<strong>for</strong>mance and precision tool in the<br />

case of thicknesses of < 0.15 mm, coating thicknesses of 0.05<br />

g/m² and even higher line speeds. At the same time, the individual<br />

demands made on the brush depend on the flatness,<br />

surface hardness of the starting material and the nature of the<br />

subsequent coating or plating.<br />

Brush roll applications<br />

Roll cleaning and polishing 2.3<br />

OSBORN’s Helimaster brush rolls are perfect <strong>for</strong> cleaning<br />

work and as back-up rolls in wet or dry operated rolling and<br />

skin-pass mills. They have been fitted to technological developments<br />

worldwide <strong>for</strong> decades, both in online lines integrated<br />

in strip lines as well as stand-alone off-line rolling<br />

stands.<br />

The rollers can work sporadically or continuously when<br />

designed as a wire or an abrasive brush. Each brush is neutrally<br />

ground at the radius and gets axially. This means that it<br />

gets either a cylindrical camber ground or, <strong>for</strong> offsetting the<br />

computed roll deflection, a positive and/or negative camber<br />

ground.<br />

In the meantime, with Lipprite ® abrasive rollers, an alternative<br />

technology, has also been developed and manufactured inhouse<br />

<strong>for</strong> skin-pass roller cleaning.<br />

The brush roller itself is only part of<br />

the solution. This technologically demanding<br />

application can only be optimally implemented with a precise<br />

matching of the brush tool to operational and process parameters.<br />

The reproducibility of the specified corrosiveness and<br />

brush effect as well as constant tool per<strong>for</strong>mance play a crucial<br />

role from the first point of use to the exchanging of the<br />

roller.<br />

Roll cleaning in a typical skin-pass mill<br />

For the cleaning of deflector, shape control or thickness measurement<br />

rolls, special wear-resistant non-abrasive plastic filaments<br />

are used. They ensure an equally thorough removal of<br />

solids and liquid materials without damaging the roll surface<br />

or altering the roughness. At the same time, the filament type<br />

and bristle diameter are dependent on the surface hardness<br />

and the degree of pollution of the roll that requires cleaning.<br />

Strip polishing and finishing<br />

When it comes to the optical finishing of strip surfaces in<br />

the <strong>for</strong>m of polishing, satinising, finishing or decorative<br />

grinding and brushing, you’re in good hands with OSBORN.<br />

Decades of experience in the machining of steel, stainless<br />

steel, aluminium and other non-ferrous surfaces have given<br />

us a technological advantage, from which our customers<br />

benefit worldwide today.<br />

In addition to high-quality wire and abrasive brushes, we<br />

can also rely on a merger with the Lippert-Unipol Group,<br />

one of the global leaders in abrasive and polishing tools, if<br />

necessary. We can combine polishing and abrasive rollers<br />

as well as polishing compounds on a selection / combination<br />

of tools and processing alternatives. This is unique in<br />

the market, which gives you the advantage of the most<br />

optimal surface finishing in your application.<br />

Today, increasingly higher demands are made on the final<br />

machining of strips. An optically perfect and homogeneous<br />

surface over an entire field of vision achieved through the correction<br />

of small surface defects in the last mechanical machining<br />

step is in high demand. This applies equally to the operators<br />

of strip lines as well as <strong>for</strong> service centres or direct<br />

processors of coils.<br />

Different types of rollers and coatings can also be used<br />

depending on the material type and quality, the surface hardness<br />

and the required finish and condition be<strong>for</strong>e the final finishing.<br />

For determining the respective optimum tool, we<br />

carry out individual pilot tests at test lines in our laboratory.<br />

UNIPOL ® polishing emulsion<br />

(liquid emulsion application)<br />

UNIPOL ® polishing emulsions are initially applied directly to<br />

the strip surface to be processed as a liquid paste in immersion<br />

baths or by means of a low-pressure, medium-pressure,<br />

high-pressure or airless spraying system.<br />

With Bessemer wire measuring diameters of 0.06 or 0.08 mm,<br />

filled rollers serve as carriers of this paste in the subsequent<br />

polishing process.<br />

Our Lipprite ® product series represents an alternative to<br />

brush rollers with a wire or abrasive bristle coating. As with<br />

grinding non-woven rollers, an absolutely uni<strong>for</strong>m fine final<br />

grind and a corresponding homogeneous surface finish can<br />

be achieved. With the correct contact pressure, the flexible<br />

roller surface is in a position similar to a brush to offset any<br />

slight unevenness of the strip.<br />

Brush roll applications<br />

Scale removal<br />

For de-scaling strip surfaces after hot and cold mill processes,<br />

our brush rollers have been setting standards <strong>for</strong> years.<br />

OSBORN’s developments and innovations in both brush constructions<br />

and filaments have in set the international standards<br />

in annealing and pickling lines or bright annealing lines<br />

<strong>for</strong> stainless steel strip.<br />

With the development of acid resistant fill materials, it has<br />

been possible to achieve tremendous quality and improvements<br />

relating to service life on numerous strip lines. This<br />

results in substantial reduction of total cost <strong>for</strong> our customer.<br />

The parallel optimisation of the brush / shaft design and operational<br />

parameters through targeted assistance on site is<br />

another important OSBORN competence based on our longstanding<br />

worldwide experience.<br />

A new brush-generation - acid proof filaments<br />

Through the development of special abrasive and non-abrasive<br />

facing materials combined with an improved level of acid<br />

resistance and excellent wearing properties, the lifetime of<br />

brush rollers in stainless steel strip lines has now been significantly<br />

increased. This allows tremendous cost savings in<br />

the <strong>for</strong>m of longer lifetimes and lower maintenance costs.<br />

Ideally, the abrasive rollers are inserted on roller systems<br />

made from hollow shafts with bore holes. Apart from<br />

improved cooling of the filaments in the continuous operation<br />

of the roller, these also provide continuous rinsing out of<br />

acid or other corrosive mediums from the brush lining. An<br />

11<br />

optimum rinse function is ensured on one hand by the correct<br />

number and size of the cooling holes and on the other hand<br />

by the amount of liquid.<br />

At the downstream strip drying operation, similarly significant<br />

process improvements and substantial cost savings can<br />

be achieved through the use of squeezing rollers, which are<br />

made of newly developed, acid-resistant, non-woven materials<br />

or through the use of vacuum systems.


Where stainless steel materials reach their limits in high acid<br />

concentrations, special protective coatings on shafts and<br />

accessories provide the optimal protection of these components.<br />

In addition, steel shafts with shock and impact resistant coatings<br />

provide cost benefits as they are an interesting alternative<br />

to stainless steel bodies.<br />

In manufacturing stainless steel flat products, OSBORN<br />

International’s intelligent solutions and innovations play a<br />

part in process optimisation and quality improvement as well.<br />

Roll coating control<br />

Almost 50 years ago, OSBORN developed a revolutionary<br />

technology using brushes in the continuous rolling process<br />

in order to optimally regulate the oxide film on working and<br />

back-up rollers in hot rolling mills. As a result hundreds of<br />

hot mills worldwide have been equipped with OSBORN<br />

technology.<br />

To date, specially designed wire qualities, abrasive multifilaments,<br />

individually camber ground surfaces and extensive<br />

experience in optimising the use of brushes in numerous<br />

individual applications have secured a major technological<br />

advantage <strong>for</strong> us in this field. The benfits from this<br />

we can pass on to our customers worldwide.<br />

body is one of the most important prerequisites <strong>for</strong> guaranteeing<br />

uni<strong>for</strong>m brushing across the entire width of the<br />

roll. Depending on the construction of the working or backup<br />

rollers to be brushed and the calculation of the optimum<br />

crown, convex or concave contours are ground. OSBORN,<br />

of course, also grinds brush rollers with a CVC contour on<br />

CVC technology mills <strong>for</strong> roller gap adjustment.<br />

Brush roll applications<br />

Transport roll systems <strong>for</strong> HHT furnaces<br />

The tempering of hot mill plates made of precipitation hardening<br />

aluminium alloys through the process of solution<br />

annealing, serves the purpose of attaining higher strength<br />

and strain values along with a good level of corrosion resistance.<br />

Today, this is required <strong>for</strong> structural parts in aircraft in<br />

accordance with the strict requirements of standards AMS<br />

2750D, AMS 2750C and AMS-H-6088.<br />

The careful transportation of these aluminium plates in ‘hard<br />

metal and hard material technology’ roll hearth furnaces<br />

takes place as a batch or continuous process at temperatures<br />

of up to 600°C on brush transportation rolls. In close cooperation<br />

with leading equipment manufacturers, numerous furnaces<br />

around the world have been equipped in recent years<br />

with OSBORN’s sophisticated technology. In the process,<br />

plates with thicknesses of up to 400mm, lengths of 20 metres<br />

and weights of over 10 tonnes do not present a problem <strong>for</strong><br />

us. Tolerances have been continually reduced and product<br />

features optimised, so that now more than ever, the brush<br />

roller is an integral and technologically superior component<br />

in the overall design of the line.<br />

Surface-sparing plate tracking with longstanding roll lifetimes<br />

With brush furnace transportation rolls, OSBORN customers<br />

can today place their trust in several decades of experience<br />

and well known global references. In the complex production<br />

of the rolls, some with a total length of over 6000mm and<br />

4000mm of brush length, the highest level of precision and<br />

reliability are required in all manufacturing processes.<br />

After the rolls have been manufactured, the later course of<br />

the sheet is accurately simulated in advance in our factory.<br />

For roll assemblies in new furnace lines, this allows OSBORN<br />

15<br />

to guarantee an optimum course of the sheet within tight tolerances<br />

even when starting up the run.<br />

In order to guarantee the lowest possible sheet tracking with<br />

the ‘re-brushing’ of entire furnace zones the transportation of<br />

the sheets is simulated on an in-house test rig just like new<br />

lines.


This advanced technology provides a convincing argument<br />

<strong>for</strong> why brushing with heat resistant wires is increasingly<br />

establishing itself as a roller cover <strong>for</strong> furnace transportation<br />

rolls.<br />

• Optimum heat transfer between the transportation roll and<br />

the plate<br />

• Longstanding lifetime without significant wear of the brushes<br />

• Complete avoidance of scale pick-up and spot <strong>for</strong>mation<br />

on the surface of the roller, just as it is the case with selfcontained<br />

roller coverings<br />

• Total-care transportation of the plates during the heat treatment<br />

without damaging the surfaces of the plates<br />

Aside from the production of new rolls, the recovering and<br />

replacement of worn brushes in older lines is also one of our<br />

core competences.<br />

By precisely measuring the course of the plate as well as the<br />

state of the individual rolls within the furnace by means of<br />

self-developed test equipment, we are able to optimise plate<br />

tracking if needed, which maximizes the output of the entire<br />

system.<br />

Brush roll applications<br />

Transport roll systems <strong>for</strong> noise reduction 2.9<br />

When transporting the sheets onto rolling tables, extreme<br />

noise levels may occur in slitting/cross cutting lines by heavy<br />

plates after the shearing process. At over 110 dB, this may<br />

possibly exceed the threshold of noise pain <strong>for</strong> the human<br />

ear.<br />

By coating the bright transport rollers with brush sections,<br />

the noise level can be reduced to around 70 dB so that any<br />

health risk to the labor <strong>for</strong>ce is significantly reduced.<br />

heavy-duty applications. Apart from improved brush cooling<br />

with greater frictional heat when used in corrosive mediums,<br />

they continuously and uni<strong>for</strong>mly rinse the brush in operation<br />

Upon receipt by our service centre, each roller immediately<br />

undergoes a professional inspection in accordance to the<br />

agreed upon service contract. The condition as well as the<br />

time and expense involved with the maintenance are documented<br />

with the aid of standardised protocols.<br />

The quiet and low-vibration running of the rollers is important<br />

in order to avoid shatter marks or shading on the strip<br />

surface caused by the brush roller. Be<strong>for</strong>e recovering, each<br />

shaft is there<strong>for</strong>e examined with regard to inbalance and concentricity<br />

deviation, in order to align it straight if necessary<br />

and to rebalance it.<br />

The longer the service life of rollers, the more important it is<br />

to have the proper condition of the bearings to avoid additional<br />

downtime or outages. For this reason, bearing units are<br />

checked and maintained by us. If necessary, the bearing unit<br />

or other accessories are renewed.<br />

Adaption/improvement of existing rolls/shafts<br />

OSBORN HDL® - the benchmark in lifetime and brush per<strong>for</strong>mance<br />

OSBORN HDL ® provides even more than this. What we mean<br />

by this concept is an optimisation approach to strip lines in<br />

regard to the various brush applications as well as the working<br />

parameters of these rollers.<br />

In the first step to find a solution <strong>for</strong> you, we will analyze the<br />

current fine weaknesses. Depending on the type of line and<br />

degree to which the brushes are required <strong>for</strong> cleaning,<br />

degreasing and surface activation, an individual covering is<br />

25<br />

defined <strong>for</strong> the roller. This covering is made from non-abrasive<br />

and/or abrasive micro fibres and monofilaments. Parallel<br />

to this, the shaft construction is optimised and adjusted. In<br />

general, the customers’ existing shafts can be used. The<br />

usage parameters of the respective brush rollers are evaluated<br />

with regard to cooling, in-feed and revolution speed. We<br />

then draw up a customized optimisation recommendation.


Compared to conventional standard brushes, OSBORN HDL ®<br />

rollers offer decisive advantages:<br />

Micro filaments improve strip cleanliness<br />

• Significantly increased lifetime and reduced operating,<br />

maintenance and overall brush costs<br />

• Improved cleanliness levels in strip cleaning, contributing<br />

to quality improvements, process optimisation and<br />

increases in line speed<br />

• Targeted and better control of the rollers due to the compact<br />

design with higher density make a significant contribution to<br />

reliability and a controlled process<br />

Unlike conventional mono-filaments with bristle diameters<br />

ranging between 0.15 and 1.5 mm, our Novofil micro-fibre<br />

material can also reach rough depths of strip surfaces. This is<br />

due to their very thin thread thicknesses of up to 0.02 mm,<br />

which brings with it significantly improved cleaning and<br />

degreasing levels. In the process, a multi-filament bristle can<br />

be made from several hundred micro fibres.<br />

Due to the extremely high density and the individual mix with<br />

new, especially hard and rigid abrasive materials, heavy soiling<br />

and coarse metallic rolling retentions are removed in a<br />

way which is better than ever be<strong>for</strong>e.<br />

Lipprite ® abrasive rollers are manufactured<br />

from abrasive non-woven<br />

flaps through radial adhesion to a<br />

core. The abrasive grinding grain<br />

made of silicon carbide (SiC) or aluminium<br />

oxide (Al2O3) is, at the same<br />

time, embedded into the surface of<br />

the random web fibre non-woven<br />

material (made of polyamide or other synthetic material) by<br />

means of resin. The corrosiveness of the roller is individually<br />

determined by the density of the material, i.e. the number of<br />

flaps.<br />

An optional additional impregnation makes the roller even<br />

more aggressive and increases the life span. It is necessary to<br />

keep in mind, however, that because of the significantly<br />

increased hardness, impregnated rollers are less flexible. As<br />

such, surface undulations can be harder to balance, which<br />

may result in a less uni<strong>for</strong>m finish or, in terms of the machining<br />

profile, visual shading.<br />

Technical data and product characteristics:<br />

• max. roller width 2000mm<br />

• max. roller diameter 450mm<br />

• Versions available with or without impregnation<br />

• Rollers are dynamically balanced in accordance with DIN<br />

EN ISO 1940<br />

Recommendations concerning the use of rollers:<br />

• Use in wet or dry operations<br />

• Optimum cutting speed 15-25m/s<br />

• Line (strip) speed or feed speed up to 30m/min. (max.)<br />

• <strong>Processing</strong> in the opposite direction to the running direction<br />

of the material feed<br />

• Optimum depth of immersion 2-6mm, depending on the<br />

roller diameter and hardness<br />

• Oscillation improves the uni<strong>for</strong>mity of the machining profile<br />

NOVOTEX ®<br />

non-woven rolls<br />

Products and applications<br />

Strip lines and rolling mills are equipped with a large number<br />

of different rolls <strong>for</strong> completely different tasks and applications.<br />

Through ever-higher line speeds and steadily increasing<br />

demands in terms of quality and process reliability, the<br />

demands made on roll covers and surfaces also increase. As<br />

such, non-woven rollers, with their special material properties,<br />

become increasingly important within the steel, aluminium<br />

and non-ferrous metal industry.<br />

Through close cooperation with one of the world’s leading<br />

manufacturers of technical non-woven materials, OSBORN<br />

has managed to develop a highly-engineered series of products<br />

under the NOVOTEX ® brand name, which are able to fully<br />

satisfy our consumers’ expectations in terms of quality, reliability,<br />

and durability at an excellent price/per<strong>for</strong>mance ratio.<br />

NOVOTEX ® - convincing in quality and profitability<br />

Material properties and technical benefits<br />

OSBORN’s NOVOTEX ® rollers are used where other synthetic<br />

roller coatings reach their limits and can no longer ensure<br />

optimum results or stable processes. Compared to rubber or<br />

polyurethane, non-woven material offers crucial advantages:<br />

• The porous structure of non-woven fabric in combination<br />

with a large pore volume makes the material compressible<br />

• It is significantly easier to avoid aquaplaning effects<br />

• Through the applied pressure of the random web on a roller<br />

core, a roll coating results which, with a hardness of up to 95<br />

shore A, exhibits an enormous resistance to being cut as<br />

well as a ‘self-healing’ effect in the event of light cuts<br />

• The capillary or suction effect when discharging the nonwoven<br />

structure provides a significantly lower amount of<br />

residual moisture in squeezing applications<br />

• In contrast to elastic, but hardly compressible rubber or<br />

polyurethane coatings, a significant adhesion effect occurs<br />

in the contact area of the strip surface that is under pressure.<br />

Taking these roll coverings into consideration, this is<br />

something that leads to significantly higher and more constant<br />

coefficients of friction.<br />

1 mm 1 µm<br />

29


• This results in excellent wear characteristics with a much<br />

higher roll lifespan in comparison to rubber or polyurethane<br />

• Due to its pore volume, the roller covering is in the position<br />

to absorb small particles of dirt, oil or grease residue<br />

as well as light roller tinsel<br />

• For a sustained period, the surface itself remains largely<br />

free of contamination or hardened material - an important<br />

criterion <strong>for</strong> permanent, reliable roll operation without fluctuations<br />

in quality<br />

• In addition, the strip surfaces are particularly conserved<br />

and protected from damage<br />

Economic benefits<br />

The material properties and technical benefits described<br />

bring about a series of economic benefits, which make the<br />

use of non-woven fabric rolls a viable option from a cost/benefit<br />

point of view:<br />

Material compressibility of non woven<br />

• Despite high acquisition costs <strong>for</strong> the individual rolls, the<br />

longer service life ensures a reduction in operating costs<br />

that significantly outweigh the initial costs.<br />

• Significantly longer lifespans <strong>for</strong> the rolls reduce downtime<br />

and thus, reduce maintenance costs<br />

The roll deflection is of crucial importance <strong>for</strong> an optimum and<br />

uni<strong>for</strong>m squeezing result over the entire width of the strip. This<br />

is especially the case in weak or undersized shaft constructions.<br />

When the feed <strong>for</strong>ce is too high the roll ‘whips’ leading to<br />

excessive residual moisture in the central area, where as too<br />

little feed <strong>for</strong>ce causes wet edges on border areas.<br />

For this reason, OSBORN International defines the optimal<br />

feed <strong>for</strong>ce <strong>for</strong> each non-woven roll and, on this basis, works<br />

out the expected roller deflection. The roll crown will be<br />

ground to either convex or concave contours.<br />

Applications<br />

Pressure rolls<br />

S-rolls / Tension rolls /<br />

Bridle rolls<br />

Squeezing rolls<br />

When used as bridle rolls, tension rolls, steering rolls or<br />

deflector rolls, the advantages of non-woven fabrics over<br />

other synthetic coatings are especially clear. In a dry state and<br />

especially in wet conditions, a non-woven fabric has an excellent<br />

and above all constant friction coefficient both on oil as<br />

well as on watery mediums.<br />

The friction coefficients of rubber or polyurethane-coated<br />

rollers, however, are very low; something which can easily<br />

lead to aquaplaning in the case of non-driven roller, e.g. a<br />

floating of the roller. This can result in strip slippage, which<br />

causes scratches and damage to the surface. On the other<br />

hand, non-woven coatings adhere well to the strip surfaces.<br />

This allows much higher tensile <strong>for</strong>ces to be achieved, and<br />

strips can be held tightly and controlled much more accurately.<br />

Even when applied to braking or tension rolls, the material<br />

properties speak in favour of the non-woven roll. Because of<br />

the strong and stable adhesion between the roll and the strip<br />

surface, strips can be evenly pulled or control-braked even at<br />

high plant speeds.<br />

Deflector rolls<br />

Squeezing rolls ensure lower residual moisture than rubber<br />

or polyurethane coatings. On account of the capillary or suction<br />

effect of the non-woven material, fluid displacement at<br />

the edges is reduced, and the strip edges dry better. In addition,<br />

the special properties of non-woven materials prove<br />

their worth in terms of resistance to cuts and durability.<br />

Transport rolls /<br />

Carrying rolls<br />

Tension rolls /<br />

Brake rolls<br />

As oiling or applicator rollers, non-woven coatings ensure the<br />

uni<strong>for</strong>m application and distribution of liquid coatings<br />

because of their sponge effect. Due to their porosity and pore<br />

volume, they are in the position to absorb liquid and, under<br />

pressure, to dispense it again evenly and/or to distribute it on<br />

the surface.<br />

The special surface protection, which is created by absorbing<br />

small dirt particles into the roller surface, is visible in pressure<br />

rollers made of non-woven material especially <strong>for</strong> soft and<br />

sensitive surfaces such as aluminium e.g. coil strips in cold<br />

rolling processes. Line speeds of over 1000m / min present<br />

no problems.<br />

Applicator rolls<br />

A similar situation applies to the use of a non-woven roller as<br />

a transporting or carrying roll. The soft and absorbent surface<br />

of the roll prevents scratches or damage, thus ensuring the<br />

smooth transfer of the strip.<br />

<strong>Innovative</strong> equipment technology<br />

Vacuum squeezing systems<br />

By connecting a pair of squeezing rolls made from special<br />

micro fibre – non-woven material with simple vacuum technology<br />

– we are able to offer an innovative, energy-saving<br />

and environmentally-friendly system <strong>for</strong> strip drying in a variety<br />

of process lines. Through this technology, which has been<br />

proven and established in Japan <strong>for</strong> decades, it is sometimes<br />

possible to replace entirely a fan or hot-air dryer. As a result,<br />

a single line can achieve annual energy savings of up to EUR<br />

100.000.<br />

Dry surfaces and very low energy consumption without hot air<br />

The function of the system is simple. The vacuum generated on<br />

the perimeter absorbs the liquid remaining on the strip surface<br />

into the roll supported by the capillary action of the micro fibre<br />

non-woven covering. Through the hollow shaft on its perimeter,<br />

which has numerous holes on it, fluid is sent via the vacuum<br />

pump to the existing fluid circuit.<br />

Significant quality and process-related optimisation is created<br />

through the vacuum technology with absolute dry strip edges as<br />

just an example. Displacement through the gap in the squeezing<br />

rollers on the edge area is eliminated entirely by the strong vacuum,<br />

and moreover, the need <strong>for</strong> subsequent expensive/laborious<br />

drying is completely removed.<br />

35


Microfibre squeezing rolls in combination<br />

with energy saving vacuum technology<br />

The advantages of the vacuum roller especially become more<br />

relevant in comparison to conventional squeezing rollers on<br />

shatter plates or extremely rough strip surfaces.<br />

OSBORN rolls function with a very soft surface and only minimal<br />

contact pressure. As such, the coating is significantly<br />

less prone to wear and essentially more resistant to damage<br />

from strip edges than in the case of traditional squeezing<br />

rolls. Without its own power, the limited in-feed of the roll<br />

preserves the condition of the rolls, as well as the bearing and<br />

the line itself. This creates a lifespan <strong>for</strong> the rolls averaging<br />

four to five years (depending on individual application) with<br />

only minimal maintenance. All that is needed is trimming<br />

operation and follow-up grinding of the roll surface from time<br />

to time.<br />

As the example below shows a typical strip cleaning line<br />

through the use of NOVOTEX ® non-woven rolls in the third<br />

and fourth exchange of the squeezing roller pair, it would be<br />

possible to dispense with the hot-air drying facility entirely in<br />

favour of a vacuum squeezing system.<br />

Squeezing rolls<br />

Vacuum squeezing system<br />

can replace hot air drying<br />

NOVOTEX ®<br />

Another important advantage is that this system innovation is<br />

extremely simple to implement into existing strip lines. Only<br />

the last pair of squeezing rolls in the plant has to be exchange<br />

out. At the same time, the external dimensions of the rolls<br />

normally remain unchanged and the existing bearings can be<br />

used. Even when additionally installed into an existing strip<br />

line, the space requirement <strong>for</strong> a complete unit with a frame<br />

construction is less than one metre width. The vacuum unit<br />

itself also requires very little space and does not have to be<br />

placed directly on the pair of rolls.<br />

<strong>Innovative</strong> equipment technology<br />

Brushing equipment <strong>for</strong> strip processing lines<br />

By linking our technological leadership in brush rollers with<br />

the competence and experience gained from teaming up with<br />

a wide range of line installers across the world, we are, in<br />

cooperation with selected partners, in the position to offer<br />

well-engineered and individually adapted brushing machines<br />

and line concepts, which go further than the established standard<br />

machinery. Our focus primarily lies in replacing old<br />

equipment, which no longer works optimally in existing lines,<br />

while at the same time optimising brush rollers and usage<br />

parameters in order to achieve sustainable quality and<br />

process improvements.<br />

New intelligent concepts <strong>for</strong> brushing machines<br />

Along with this background, we are also able to offer a new, fully<br />

patented machine package which includes a variety of innovative<br />

developments:<br />

• A rigid machine housing which is heavily cushioned against<br />

vibrations and protected against corrosion made of a composite<br />

stainless steel/mineral cast construction<br />

• Compact and extremely dense OSBORN HDL ® brush rollers enable<br />

precise control of the depth of immersion<br />

• Easy and quicker replacement of the rollers within a few minutes<br />

using an insertion skid with no additional dismantling tools<br />

• Compact design enabling the unit to require little space - only<br />

1500 mm <strong>for</strong> each upper/lower brush <strong>for</strong> strip widths up of to approx.<br />

2000 mm<br />

• Easy and precise positioning of the rollers through mechanical<br />

clamping<br />

• Optimum and reliable feeding of the brush rollers via the immersion<br />

depth by means of height adjustment using precision lifting spindle<br />

elements with a servo positioning motor (parallelism tolerance<br />

approx. 0.1 mm)<br />

• Replacement of the rollers without disassembling the bearing units<br />

• Optical control at any time through side access doors with large windows<br />

on the operator side and the interior lighting of the plant<br />

• Non-contact measurement of the roller diameter in operation<br />

• Optional construction according to the brush/brush principle<br />

For many years, Japanese lines have maintained a leading<br />

role in technology. In recent years, we have been able to successfully<br />

combine new line projects with renowned steel producers<br />

in Europe, North America, Asia and Africa together<br />

with our Japanese partners by adjusting the components to<br />

international standards.<br />

• With these lines, the brush/brush principle instead of the<br />

conventional brush/back-up roll design provides a number<br />

of advantages.<br />

• Due to the reduction of required roll pairs by half, a 50%<br />

space saving is achieved.<br />

• In the case of thin straps, the brush in the border area no<br />

longer works on the back-up roll but combs in the opposite<br />

brush. Fully uni<strong>for</strong>m wear of the brush balling is achieved in<br />

the border area through the additional oscillation of the<br />

rolls.<br />

• In all, the per<strong>for</strong>mance of the respective strip cleaning unit<br />

is significantly improved. As a result, strip quality and line<br />

speed can be increased.<br />

• Acquisition and maintenance costs are correspondingly<br />

reduced.<br />

• Above all, when exchanging brush machines in existing strip<br />

lines, valuable space <strong>for</strong> additional pre-cleaning sections<br />

can be achieved in addition to more intensive brushing.<br />

• The contact surfaces strip/upper brush and strip/lower brush<br />

are identical. This reduces vibrations. Through gentler running<br />

of the strip, shading and shatter marks on the<br />

strip surface are avoided.<br />

Shafts <strong>for</strong> Yoke Style Idler-Rollers<br />

Load Runners ® idler rolls are tightly sealed and greased <strong>for</strong><br />

their entire service life. As such they are insensitive to dirt,<br />

moisture and extreme temperatures. Long-life and maintenance-free<br />

operation ensures high levels of economy.<br />

The treads are made of high-strength steel and are then surface<br />

hardened to 55-60 HRC. As such, they feature an especially<br />

wear-resistant surface with a tough core.<br />

The precision tapered roll bearings and grooved ball bearings<br />

used are particularly suitable <strong>for</strong> both radial and axial loads<br />

and can even be used at high speeds. This secures key advantages<br />

over conventional needle bearings.<br />

Precision adjusted and hardened guiding rails made of highduty<br />

alloy steel are extremely resilient, wear resistant and<br />

free from twist effects. As such, heavy loads can be moved<br />

precisely and reliably.<br />

An optimal brush result is determined by different parameters.<br />

After selecting the appropriate bristle, brush design,<br />

fill density and trim length in the process, we focus on the<br />

correct operational parameters.<br />

Criteria such as surface speed, brush speed, depth of<br />

immersion and contact pressure have to be taken into<br />

account and individually defined under the given framework.<br />

Different applications and fill materials require different<br />

speeds, and the appropriate speed depends on the roll<br />

diameter.<br />

The optimum contact pressure can vary greatly as well and<br />

depends on the brush construction and the fill density. The<br />

decisive factor in achieving the required brush result is the<br />

immersion depth, as a brush tool works primarily with the<br />

bristles and/or the tips of the wire.<br />

Optimal brush per<strong>for</strong>mance is achieved through the use of<br />

compact brushes and high quality fill materials.<br />

Consequently, cooling plays a crucial role, as overheating<br />

can quickly lead to the bristles becoming brittle causing<br />

premature breakage. The brush cooling facility in the plant<br />

/ line is optimised by correcting and adjusting the angle of<br />

spray and flow rate. In turn, this significantly extends the<br />

lifespan of the rollers. The selection of the correct spray jets<br />

also plays an important role.<br />
