Recently, China Steel Casting a successful Xing machine weighing 41.9 tons, has a diameter of 1350 mm large-scale high - chromium steel roll. After testing, the technology to achieve data requirements.

　　Φ1350 mm high chromium steel roll, as diameter, weight tonnage, technical process difficult to achieve, and other factors, the domestic manufacturers Roll no corresponding capacity. With the hot-rolled steel strip Xing centrifugal machine roll production line capacity expansion and technological transformation projects in China Steel Xing machine has been developed with large centrifugal Roll conditions, in order to meet China's major iron and steel enterprises strip mill work for the needs of a basis.
