Chinalco Aluminium Company Limited of China has placed orders with Siemens VAI Metals Technologies for two additional finishing stands for the aluminum hot rolling mill of Chinalco Ruimin Company Limited in Mawei, Fuzhou. The extended order has a volume of around EUR 15 million and is due to be completed in September 2009.

Chinalco had already ordered the supply of the mechanical and electrical equipment of a single stand finishing mill in the fall of 2007.

The finishing mill, to be equipped by Siemens will have a total of three four high stands with automatic hydraulic roll gap control and positive and negative work roll bending.

This will raise the planned capacity of the 2.4 meter hot rolling mill to 375,000 tonnes per year. In addition to the mechanical equipment, Siemens will also supply the complete automation system and the drive systems, including Sinamics SM150 medium voltage converters and Sinamics S120 low voltage converters, as well as the sensors. The automation system will include the basic automation including the technological control systems and the human machine interface equipment.

The scope of supply also encompasses the process automation for the entire hot rolling mill. The resulting integrated system will ensure a consistently high product quality. All systems and components used are part of “Siroll Alu,” the integrated solution platform from Siemens for aluminum hot rolling mills. Siemens will also be responsible for commissioning and training.
