摘　　要：根据在湿磨条件下对球磨机衬板性能的要求,设计并制造出一种综合性能较好的低碳高合金钢衬板材料。该材料组织为板条马氏体,HRC45～50,冲击韧性αk=50～90J/cm2。冲击腐蚀磨损实验结果表明:低碳高合金钢比高锰钢具有更好的耐冲击腐蚀磨损性能。装机结果显示:该低碳高合金钢衬板的使用寿命是高锰钢的2倍左右。According to the demand for the properties of ball mill liner in wet grinding environment, a novel high alloy mild steel liner, which microstructure is lath martensite and possess better comprehensive properties, was designed and manufactured. The hardness of the steel is HRC 45-50 and the impact toughness α_k is 50-90 J/cm^2. The experimental results show that the impact-corrosion wear property of the high alloy mild steel is superior to that of high manganese steel. The field test shows that the service life of the liner made from the steel is two times as long as that of one made from high manganese steel.
