Wear-resistant composite liner has high wear resistance, impact resistance and weldability.
1, high wear resistance. The chemical composition of the alloy layer has a carbon content of 4-5% and a chromium content of 25-30%, the volume fraction of cr7c3 carbide in the metallographic structure reaches more than 50%, the macro hardness is hrc56-62, and the hardness of chromium carbide is hv1400-1800, which is higher than the hardness of quartz in the sand and stone hv800-1200. Because the carbide is vertically distributed in the wear direction, the wear resistance is more than doubled compared with the cast alloy with the same composition and hardness.
2, high impact resistance. The composite wear-resistant lining has high impact resistance, which fully embodies the advantages of both wear resistance and impact resistance of the composite material. Can withstand impact and wear such as high drop hoppers in material handling systems.
3, the greater the material processing capacity, the more serious the equipment wear of iron and steel metallurgy, building materials machinery, electrical machinery, mining machinery, cement industry, fan and other industries to use wear-resistant composite liner economic effect is more obvious.
