Early in 2016, Acerinox Europe placed an order with SMS
group for the installation of a 20-high cold rolling mill for
high-quality stainless steel grades. With this third order within just a
few years, Acerinox is continuing its successful cooperation with SMS
Acerinox has always placed high value on the upgrading and the
technological advancement of its production facilities. Also in 2016,
Acerinox remains true to this principle by investing in its main
production facility in Los Barrios, Cadiz, in Spain. There, SMS group is
going to install a new 20-high cold rolling mill in MonoBlock design of
size MB22B-52“, complete with X-Pact? electrical and automation systems.
Beside the MonoBlock millstand, the mechanical scope of supply
comprises a separate pay-off unit, two reversing reels with paper feed
and utility systems, including hydraulics, a SUPAFINE? rolling oil plant, CO2 fire extinguishing system, fume exhaust system and filter.
The compact and robust cold rolling mill will be characterized by
high stand stiffness and designed to roll a complex variety of
materials, including ferrite, austenitic and duplex steels, with high
pass reductions to a minimum final gage of 0.15 millimeters. The maximum
strip width will be 1,320 millimeters and maximum rolling speed 800
meters per minute.
The mature rolling technology from SMS group meets Arinox’ high
demands in terms of mill productivity and the quality of the products
rolled. The millstand will be equipped with hydraulic gap control and
roll crown adjustment for backup shafts B/C and F/G, as well as shifting
of the inner intermediate rolls.
SMS group will equip the mill with X-Pact? electrical and
automation systems, ensuring optimal utilization of the rolling mill.
They will include the power supply systems, drive technology and
technological control systems as well as the model-based setup system.
The latter allows high-precision imaging and precalculation of the
rolling process for the accurate presetting of the millstand. The
20-high cold rolling mill is scheduled to start operation at Acerinox at
the end of 2017.
With this third order, Acerinox continues to rely on cold rolling mills from SMS group.
At the production facility of Bahru Stainless in Johor, Malaysia,
the company has been operating a 20-high cold rolling mill since 2012.
At the production site of North American Stainless in Kentucky, SMS
group is currently installing a 20-high cold rolling mill ordered by
Acerinox for the production of bright-annealed stainless steel strip.
