Description

technical field [0001] The invention relates to a method for preparing a roll ring, in particular to a wear-resistant high-speed steel roll ring and a preparation method thereof, belonging to the technical field of high-speed steel roll rings. Background technique [0002] Roll rings are key tools in wire production and must be able to withstand considerable forces and heat. In addition to good fracture resistance, the surface should also have good wear resistance and heat resistance. Therefore, the research on improving the wear resistance of the surface of hot-rolled roll rings has attracted attention at home and abroad, and the materials of hot-rolled roll rings have been continuously improved and developed. Chromium cast steel, high-speed steel and cemented carbide, which are widely used abroad, are roughly the development process of hot-rolled roll rings. Chinese invention patent CN101596553 discloses a high-speed steel roll ring applied to high-speed wire rod mills a...
