Resistant liner excellent wear resistant liner composite alloy liner 
 Tangyin excellent wear-resistant materials 

 The ball mill dual metal alloy composite resistant liner company and Department of Materials Science and Engineering, Central Iron and Steel Structure Material Research Institute jointly developed the new generation of patented products. 

 As we know, high manganese steel, good toughness, and surface hardening. The material used in the manufacture of ball mill liner is easy to produce plastic deformation, cut off fixed screw bolt, there Slump accident, and surface hardening due to the use of the process was not significant, can not play the high-manganese steel wear potential. 

 Chrome multi-generation product of the high-manganese steel liner of carbon steel liner, tissues is mainly martensite, the high initial hardness, high hardness of the carbide content is small, anti-wear performance continued to suffer from the limitations of its life just high manganese steel liner doubling. 

 Bimetallic alloy composite liner wear face of high-chromium alloy cast iron, the microstructure of the eutectic carbide M7C3 + secondary carbide + martensite + retained austenite 
 With very high hardness (HRC ≥ 58) also has enough toughness. Non-working low-carbon steel, thermal compound, the overall toughness of the high-chromium alloy cast iron and steel fusion as a whole, the composite liner 
 Better, the appropriate solution to the problem of hard and tough can not have both. It applies to the mill of large, medium and small (Φ2500-Φ5500) models 
 . In the safe operation of the Tangshan Iron and Steel 550/880 oversize ball mill, and further prove that the bimetallic composite liner and a good toughness and a sufficient degree of reliability. 
 Bimetallic alloy composite dovetail since solid 
 Resistant liner (not bolts), a thorough summary leakage pulp mill in the production process, powder leakage problem, reducing the noise, convenient installation, zero maintenance, civilized production, while using new alloys and nurture treatment process. Liner under different working conditions and boundaries of qualitative requirements, moderate increase of nickel, molybdenum, vanadium, titanium, copper and other alloys, higher face hardness of HRC58-63, non-face was changed to high-quality carbon steel, the overall toughness better reach of ak ≥ 15J/cm2. Longer life, to get the user high praise. 

 The lining of high hardness, and high hardness of the steel ball match ball consumption can also be reduced under different conditions, different hardness of the liner design. 

 Lining the long life, no deformation, constant bolt, reducing the amount of maintenance and overhaul times, reduce labor intensity, improve the effectiveness of the work, reducing the cost of milling.
