Abstract：
The process optimization practice of large wear-resistant alloy steel liners was introduced. By adjusting the
chemical composition and designing the heat treatment process, the liner castings with excellent indexes were obtained. The
results show that the average wear rate of 1# liner is 0.528 mm/10,000t, and that of 4# liner is 0.496 mm/10,000t. It is
estimated that the ore amount of 4# liner can be increased by 6.38%.
