Aperam operates six production locations in Europe and Brazil, with an annual capacity of 2.5 million metric t of stainless flat products for a wide range of applications. The company is quoted on the stock exchanges in Amsterdam, Paris and Luxembourg. The most important European production sites for stainless steels are Châtelet and Genk in Belgium, and Gueugnon and Isbergues in France. In Genk, Aperam produces hot and cold rolled AISI grades 300 and 400 in coils weighing up to 45 metric t.
For the upgrade, Primetals Technologies supplied new electrical equipment, such as automation material, motors and drive for the annealing and pickling line. This included 30 main drives for the entry section, the pinch rolls, the bridle rolls, and the exit section. A total of 99 geared motors were also installed, for example for strip transporting at the conveyors, the furnace and the pickling plant, as well as for the paper winders and unwinders. 25 adaptation frames for new motors and existing motors were installed, as well as 17 new gear boxes including their adaption frames. The reducer units for the pinch and bridle rolls were replaced. The coilers and uncoilers retained their gear units. These measures increased the processing speed of the line from 100 to 120 m per minute. At the same time, the head and tailing-out speeds in the entry and exit sections were prepared for an increasing from 20 to 50 m per minute. To increase the capacity of the three loopers, their length was extended and new dolly cars and winches were supplied. The two existing loop pits were removed, and were replaced by new bridle rolls and an advanced tension control system. At the entry of the line, a new pinch roll was installed. Also, an additional bridle roll was installed and an existing one replaced.
Primetals Technologies also improved the strip tension control and strip stabilization on the line by modifying the plant layout. The strip looper was decoupled, and new components installed upstream of the furnace entry and the entry into the pickling section. Furthermore, the plant was equipped with a new strip tension measuring system required for strip tension control.
