INSURAL dosing furnace lining for aluminium<br />
foundries.<br />
costs. The dosing equipment uses a gravimetric<br />
load cell to ensure highest<br />
dosing precision for best metallurgical<br />
results as well as repeatability and traceability.<br />
COVERAL MTS fluxes are a<br />
range of new granulated treatment<br />
agents to cover the principal foundry<br />
operations of cleaning, drossing, modification<br />
and grain refinement. They<br />
have been specially formulated for use<br />
in conjunction with FDU and MTS which<br />
keep smoke and fume to a minimum.<br />
Shaft and rotor design are continuously<br />
improved to offer high efficiency in<br />
degassing at long service life.<br />
The longevity of a die coating is<br />
essential for the die casting process.<br />
Short lifetime leads to interruptions for<br />
touch-up, problems with mould filling<br />
and surface quality of the casting.<br />
The DYCOTE Safeguard products are<br />
nano-ceramic top coatings to be<br />
applied on top of the existing insulating<br />
DYCOTE base coating to increase the<br />
lifetime up to 300 % (depending on<br />
application). The longer lifetime leads<br />
to reduced interruptions for touch-up<br />
and therefore increased productivity.<br />
Foseco has recently launched the<br />
FEEDEX NF1 range of exothermic feeders<br />
designed for aluminium applications.<br />
The sleeve material is highly exothermic,<br />
provides a quick ignition and<br />
has a high strength and due to its excellent<br />
feeding performance, manual<br />
application of exothermic powders is<br />
avoided thereby reducing emissions.<br />
Furthermore the company offers a<br />
complete range of silicon carbide and<br />
clay graphite crucibles, retorts and<br />
other specialized shapes for use in fuel<br />
fired, induction and electric resistance<br />
furnaces. In the Non Ferrous metal<br />
transfer area crucibles from the ENER-<br />
TEK and DURATEK family highlight the<br />
energy and cost saving potential in melting,<br />
holding, and metal processing furnace<br />
applications.<br />
Monolithics also now play a significant<br />
role in modern aluminium foundries.<br />
Foseco’s ALUGARD low-cement castables<br />
and TRIAD no-cement castables<br />
contain a new aluminium “non-wetting”<br />
additive giving excellent resistance to<br />
corundum development across a wider<br />
temperature band, while the dry-vibratable<br />
lining KELLUNDITE is ideally suited<br />
to coreless induction melting furnaces.<br />
INSURAL multi-part and highly insulating<br />
dosing furnace linings for aluminium<br />
foundries combine energy savings<br />
with long-service life and resistance to<br />
oxide build-up.<br />
The use of energy efficient dosing<br />
furnaces is seen by many as the best<br />
available technology today. Foseco is<br />
now able to supply a new multi-part<br />
and highly insulating lining made of<br />
INSURAL which is delivered ready to<br />
install. Installation can be achieved in<br />
less than 3 days with no ongoing hydrogen<br />
issues and due to a totally dry installation<br />
process no sintering of the<br />
lining is necessary. Energy saving can be<br />
as high as 17%. www.foseco.com<br />

AGTOS<br />
Concept for blasting lightweight parts<br />
At the EUROGUSS exhibition, which<br />
takes place from 14 to 16 January 2020<br />
in Nuremberg, AGTOS will be addressing<br />
the distortion-free blasting of<br />
lightweight aluminum and magnesium<br />
components.<br />
The surface treatment of complex<br />
workpieces made of aluminum and magnesium<br />
is becoming increasingly demanding.<br />
Customers request a uniform surface<br />
finish on the entire component. In<br />
this context, the reproducibility for mass<br />
parts is important. Therefore, this topic<br />
complex is a focal point in the development<br />
of new blast machines at AGTOS.<br />
For example, special blast machines<br />
were developed for the machining of<br />
lightweight components and aluminum<br />
and magnesium die-cast parts. Actually,<br />
aluminum is used as abrasive as well.<br />
Considering the specifics of the material,<br />
this has implications for the design<br />
of the machines. The special features<br />
are presented at the AGTOS stand.<br />
The most important issue after<br />
investing in a blasting machine is the<br />
operating costs. With the help of the<br />
AGTOS Hanger type blast machine for Aluminium parts.<br />
right concept and the right turbines,<br />
these can be minimized accordingly.<br />
The service starts at AGTOS during the<br />
consultation and does not end with the<br />
commissioning. The visitors are cordially<br />
invited to convince themselves in personal<br />
conversations. In existing blasting<br />
machines, an increase in performance<br />
can be achieved. For example, turbines<br />
developed specifically for this application<br />
work more gently. Furthermore the<br />
abrasive consumption is lowered.<br />
