HSS ROLLS Material
The high-speed steel roll material contains high alloy elements such as vanadium, tungsten, chromium, molybdenum, niobium, etc. The types of carbides in the roll structure are mainly MC type and M2C type. Compared with ductile iron rolls and high-nickel-chromium rolls, the single-groove (time) steel passing is higher, which saves roll changing time, improves rolling mill […]

Work Roll Material Selection The work rolls of rolling mill roll before rough rolling (R1): Work rolls before rough rolling must have toughness, wear resistance and thermal crack resistance. The hardness range is about HS40-55. Generally, 60CrNiMo cast steel and other material rolls are used. Work rolls after rough rolling (R2): The work rolls after […]
