摘　　要：针对常用磨球脆性大、耐磨性低、磨耗高的缺点,研制了多元低合金贝氏体铸钢磨球。这种磨球具有硬度高、硬度均匀性好和韧性高等特点。用于磨矿生产,磨耗接近高铬铸铁球,成本降低30％～40％,综合效益显著。To counter the situation that usual grinding ball has high brittleness,low wear-resistance,high wear-consume,we research multielement low alloy bainitic cast steel grinding ball,it has high and even hardness and high toughness. Being used in grinding ore production,its wear-consume is near to high chromium cast iron grinding ball's,its production cost is 30%-40% less than high chromium cast iron grinding ball's,good economical benefit is obtained.
