Siemens to equip new tandem cold rolling mill for Novelis in Korea
Novelis is planning to construct a tandem mill to increase the capacity of the cold aluminum rolling plant in Yeongju, Korea. Siemens will supply all the electrical engineering and equipment, including the basic automation, the human-machine interface equipment and the associated sensor systems. The technological control systems - with integrated gauge-, strip tension- and flatness control - are an important part of the automation equipment. They are required in order to achieve the extremely tight manufacturing tolerances demanded for the end product. The scope of supply also includes a Level 2 process computer which will enable the presetting of the stands to be calculated online in advance on the basis of analytical mathematical models. All the drive systems, which include main and ancillary motors, will be powered by three-phase current. Siemens will install synchronous main motors for the stands and reels. Sinamics SM150 medium-voltage and S120 low-voltage converters will be used in the drives. All the systems and components used will be taken from the integrated Siroll ALU solution platform for aluminum cold rolling mills. Siemens will also be responsible for supervising installation work, commissioning and customer training.
The main factor that contributed to Siemens winning the order was the excellent experience gained by the aluminum producer during previous projects. In 2010 Novelis ordered from Siemens the electrical equipment for an almost identical tandem rolling mill in Pindamonhangaba, Brazil. Siemens has also recently been entrusted with expanding the hot aluminum rolling mill in Ulsan, Korea. Novelis Korea Ltd. is a subsidiary company of Novelis Inc., Atlanta, USA, a leading producer of aluminum and aluminum products. Novelis Inc. runs some 30 production plants located around the world and is the market leader in rolled aluminum products and aluminum recycling.
