摘　　要：介绍了大型耐磨合金钢衬板的工艺优化实践。通过调整化学成分、合理设计热处理工艺,获得了各项指标优异的衬板铸件。结果表明,在整个寿命周期内,1#材质衬板的平均磨损率0.528 mm/万t,4#材质衬板的平均磨损率0.49%mm/万t。经估算,4#材质衬板处理矿量可提高6.38%。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/10,000 t,and that of 4# liner is 0.496 mm/10,000 t.It is estimated that the ore amount of 4#liner can be increased by 6.38%.
