Siemens Energy and Automation (SE&A), Alpharetta, USA, has received an order from China’s Taiyuan Iron & Steel Company (Tisco) to equip five reversing cold rolling stands with drive and automation systems.
The order is said to be worth around $30 million and the new equipment is scheduled to start operating in 2005.
Tisco is a manufacturer of steel and special steels. Located in Taiyuan in Shanxi province, the company is currently expanding its capacity for manufacturing special types of steel. A consortium consisting of SMS Demag and Siemens is installing five multi roll reversing cold-rolling stands.
For these new cold rolling mills, Siemens is supplying a total of 15 synchronous drives, each with an output of four megawatts. The motors will be driven by voltage source converters of the new type Simovert ML2. For the basic automation Simatic S7 controllers will be used.
Apart from project management, Siemens will also be responsible for the engineering, supervision of the installation work and commissioning of the equipment.
