摘　　要：通过对铬系合金铸造磨球使用钇基重稀土进行孕育变质处理，及微合金化和优化热处理工艺等技术措施，在减少铬、钼、镍、钒、铜等贵重稀缺金属元素用量的同时，显著提高铸造磨球的综合力学性能。For chromium grinding ball casting, the yttrium based heavy rare earth element is used for inoculation and micro-alloying. The heat treatment process is also modified accordingly. The consumption of chromium, molybdenum, nickel, vanadium, copper and other valuable element can be reduced. At same time, the mechanical properties of grinding ball casting is improved.
