March 2007 — Specialty steelmaker Ugine & ALZ Belgium NV, part of the Arcelor Mittal Group, has placed an order with SMS Demag, Germany, to supply the essential components for a CVC® four-high reversing cold mill.

The overall plant will consist of a CVC four-high reversing stand, supplied by SMS Demag in 1988 to what was then Arbed. SMS Demag will modernize the plant, which has meanwhile been acquired by Ugine & ALZ, and is re-erecting it at the Genk location. The plant will be used for producing cold-rolled AISI 300 (austenite) specialty steel with good surface quality.

The reversing mill will be designed to roll hot strip with maximum incoming gages of up to 5.0 mm. The cold-rolled finished product will have final gages of 0.6 to 3.0 mm and strip widths of 800 to 1,600 mm.

Equipped with CVC technology, HS shifting system, and work-roll bending, the mill stand will be adapted to the requirements of specialty steel production. It will also include a modified system for the rapid changing of the work rolls.

SMS Demag will complete the plant with the necessary coil-conveying equipment and new entry and exit sections for the mill stand. These new plant components will help to increase the rolling capacity of the stand, to reduce the non-productive times required for coil loading and discharging and, consequently, to optimize the productivity of the overall plant.

The stand will have a maximum rolling force of 22 MN at a maximum rolling speed of 800 meters/minute. The motive power of the electrical main drives will have a total capacity of 13,000 kW.

The installation of four-high stand technology enhances the cold rolling technology previously installed by SMS Demag at the Genk location, which included CVC-6 stand, multi-roll cold-rolling stand, and CVC-2 stand.

SMS GmbH is the holding for a group of companies internationally active in plant construction and mechanical engineering relating to the processing of steel, non-ferrous metals and plastics. The group is divided into the Business Areas SMS Demag and SMS Meer (under SMS metallurgy) and into the Business Area SMS Plastics Technology. In the year 2005 some 9,250 employees worldwide generated a turnover of about EUR 2.33 billion.
