  • Description Detail:Due to vertical mill low energy consumption, the newly built large-scale cement production line adopts vertical mill as basic raw material/coal grinding, even cement mill, the largest vertical mill output can reach 600-600 tons/hour, while the roller is required with reliable against fracture and abbrasive wheel wear resistance.Usually adopt four types alloy: Mn steel, NihardIV alloy, high Cr alloy, Hardfacing (surface overlaying).Although Mn steel to surface overlaying, the material hardness is more and more big, the wear resistance improved, but its brittleness has been greatly increased at the same time, the risk of fracture is also growing. So how to choose the material with high resistance to wear and can prevent fracture become the important determinants of vertical mill spare parts materials.
