Siemens Upgrades Plate Mill at Xiangtan Iron & Steel
01/19/2010 - Siemens VAI Metals Technologies has received an order from Hunan Valin Xiangtan Iron & Steel Co. Ltd. to supply equipment for a PowerEdger and a pre-leveler. These new plant components will be installed in the 5-meter plate mill, located in Xiangtan, Hunan Province.
Siemens VAI Metals Technologies has received an order from Hunan Valin Xiangtan Iron & Steel Co. Ltd., a Chinese steelmaker, to supply equipment for a PowerEdger and a pre-leveler. These new plant components will be installed in the 5-meter plate mill, located in Xiangtan, Hunan Province.
The new plant is scheduled to start producing high-quality plates for shipbuilding and pipeline construction by the end of 2010. The new edger and pre-leveler are expected to come into operation by the middle of 2011.
Siemens VAI will engineer and supply the main components of the PowerEdger mill stand and a pre-leveler in the Xiangtan plate mill. The new PowerEdger is said to provide about 50% more torque and 80% more compressive force than conventional solutions. The main drives of the edger stand will be fitted with high-torque synchronous motors, which will be powered by Sinamics S120 DC link converters.
Siemens VAI says that the PowerEdger has been designed to meet future heavy plate requirements such as greater final thicknesses—expanding the product range and increasing the output of the rolling line. The pre-leveler is fully hydraulic and ensures optimal plate flatness, according to Siemens VAI. It will be installed directly upstream of the Mulpic cooling system.
Scope of supply also includes the instrumentation and the adaptation and integration of the additions into the plate mill automation system. The overall solution for the rolling line is based on the integrated Siroll PM concept for plate mills. Siemens will also be responsible for supervising the installation work and commissioning.
The Hunan Valin Iron & Steel Group produces some 9 million tonnes of crude steel and 8 million tonnes of steel products per annum. These products include tubes and pipes, bars and wire rods, steel sections, and hot-rolled plates. In order to add wide heavy plate for shipbuilding and pipeline construction to its range of products, the company is currently constructing a 5-meter plate mill in the plant of its subsidiary, Xiangtan Iron & Steel Co., in Xiangtan, Hunan Province, Central China.
