Typical high-speed steel roll metallurgical organization, by the martensite (or bainite) matrix plus high hardness MC, M2C, M6C and M7C3 and other types of carbides. Domestic research and application of high-speed steel rolls have also been reported, the General Research Institute of Iron and Steel in China took the lead in the development of high-speed steel rolls, and in the hot-rolled narrow strip mills and bar mills to obtain good results. Beijing Metallurgical Equipment Research Institute, Xi'an Jiaotong University, Henan University of Science and Technology, Xingtai Rolling Mill and WISCO Rolling Mill and other units, followed by in-depth research on the preparation technology of high-speed steel rolls, successfully developed high-speed steel rolls have been used in high-speed wire rod mill and bar mill. In addition, the solidification process, heat treatment process, mechanical properties and wear resistance of high-carbon high-speed steel rolls with in-depth study. In order to improve the solidification of high-speed steel rolls organization, improve its mechanical properties, the domestic also studied the high-speed steel rolls metamorphic treatment methods, significantly improve the organization and performance of high-speed steel rolls.
