Xining Special Steel Co., Ltd, the Chinese company, Qinghai Province, producer of high-grade and specialty steel, has recently granted the SMS group the final acceptance certificate for the successfully commissioned mill for semi-finished products.
Mill for semi-finished products at Xining
The mill comprises a reversing roughing stand and a finishing mill with eight HCS® (Hydraulic Compact Stands) in horizontal/vertical arrangement. All millstands are equipped with roll adjustment systems and hydraulic systems for axial adjustment of the rolls. In combination with a control concept and an integrated inline profile gauge (MEERgauge®), this innovative rolling concept sets new standards in terms of dimensional accuracy of the final products and economic efficiency of the mill. For the first time, it is possible to roll even large round bars within narrow rolling tolerances.
Even the narrowest rolling tolerances in the range of ¼ of the DIN EN value can be achieved, thanks to the hydraulic adjustment mechanisms in combination with the latest measuring technology. Furthermore, the ASC® control system (Automatic Size Control) allows quick and automated adjustment of the finishing mill, saving time and money.
Xining Special Steel is now able to produce high-quality round bars from high-grade and specialty steel in diameters between 80 and 280 millimeters at an annual production capacity of 800,000 tons.
