At present, a lot of low chromium cast iron factories, mines and ports to use, high chromium cast iron liner is much higher than the hardness of the high manganese steel plate hardness. High chromium cast iron eutectic carbide (CrFe) 7C3 Scaleboard hexagonal, hardness HRM501200-1800, higher than the average white iron eutectic carbides Fe3C3 (HRV50840-1100), at the same time by calling The basic organizational quality, toughness than ordinary white cast iron greatly improved. At home and abroad for high chromium cast iron wear mechanism, fracture toughness, crack propagation mechanism, a series of studies, the results show that high chromium cast iron carbide can be adjusted to the size and shape, and the dispersion of the amount of secondary carbides and matrix organization (horse martensitic, austenitic, patenting), thereby adjusting the performance of high-quality ball mill liners, meet the requirements. In recent years, China has carried out a study of the relevant units of high chromium cast iron liner, the same conditions the wear resistance of up to 2 times of high manganese steel. But the toughness of these materials are thin and low alloy elements containing molybdenum, copper and other mill liner uses, higher production costs. Huanghua Port and Dalian-source environment limited liability company jointly carried out by the port development of high chromium cast iron liners, and has made good use of effects is too thin, ball mill liners use a short time, near the fan to replace a larger investment and trouble, too thick mill liner ball mill liners longer life cycle model, but lining their own weight to bring heavy grinding mill, ball mill too thick liner occupy positions within the volume decrease in the warehouse area of ??the mill, grinding material cavity smaller The corresponding efficiency is low, how to configure the mill liner is more appropriate? Zhengzhou Jinyang Machinery tell you based on years of experience under normal circumstances is a replacement liner period a year better, the thickness of the best maintained at about 6 cm.
