Fives launches new strip processing line concept
Fives introduced its new NeoKoil ®
SmartLine processing line solution at
the China International Import Expo
(CIIE).
Utilizing its expertise as an international
industrial engineering group, Fives developed
the new technology to help steelmakers
meet the increasing demand for
high value-added steel grades. This fully
automatic strip processing line is based on
predictive modelling to enable the best
quality yield and optimal productivity.
“NeoKoil ® SmartLine uses predictive
metallurgical models combining physical
laws and artificial intelligence to automatically
achieve best quality and productivity
results. Predictive metallurgical models
are a key feature of the line. They are
developed by Fives experts taking into
account the entire processing history of
the product. The models consider the
effects of upstream slab production,
annealing, cooling, galvanizing, and the
skin-pass reduction process. The NeoKoil ®
SmartLine enables a shift from predefined
setpoint management for each steel grade
to automatically achieving optimal setpoints
for the entire process and the
desired steel grade properties.

Shougang Jingtang, located in the Caofeidian
Industrial Area, Tangshan city in
the Hebei province, is seeing the commissioning
of the first Danieli Universal
Endless (DUE ® ) plant.
DUE ® is a new concept of combining
thin-slab casting and rolling within a single
production line. The DUE ® plant at
Shougang Jingtang has already
achieved the important milestone of
producing the first coil in full endless
mode: in the dimensions 3.0 mm x
1,250 mm, in medium-carbon grade,
and after rolling just 45,000 t of hotrolled
coil since commencement of the
hot tests. The single-strand thin-slab
caster has been regularly producing
slabs reduced from 130 mm to 110 mm,
using Danieli’s dynamic soft reduction
technology. Coil-to-coil rolling has
already become a consolidated production
practice as has semi-endless rolling.
In addition, the company has had its
hot rolling line 2250, in operation since
2008, refurbished by Danieli Service.
The project included, among others,
milling of the lower lateral surfaces of
the F1 and F2 housing stands, 3D laser
inspection and laser cladding, refinishing
of a total of eight pin holes on stands
F1, F2, F3, and F4, applying a special
high-speed flat polishing process to
address housing roughness.

Nanjing Iron & Steel to upgrade Steckel mill
Nanjing Iron and Steel Co. (NISCO) has
contracted Danieli to upgrade its 3500
mm Steckel mill with hydraulic automatic
gauge controllers.
HAGC (hydraulic automatic gauge controllers)
are critical components in flat
rolling mills for the achievement of rolled
product thickness within tight target tolerances.
The project will be handled by
Danieli Service, which provides steelmakers
with consultancy services and
full customer support through equipment
and process upgrades. The equipment
for Nanjing will be designed and
manufactured in the Danieli manufacturing
centres.
