STUDY AND APPLICATION OF MULTICOMPONENT LOW-ALLOY BAINITIC CAST STEEL GRINDING BALL
-
摘要: 针对常用磨球材质脆性大, 耐磨性低, 磨耗高, 研制了多元低合金贝氏体铸钢磨球。该磨球具有硬度高、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。Abstract: The multicomponent low-alloy bainitic steel grinding balls have been invertigated in accordance to normal grinding balls with high brittleness, low wear-resistance and high wearing-away. The grinding balls are characteristics of high hardness, good uniform hardness and high toughness. By comparision with high chromium cast iron grinding balls, the wearing-away is nearly close to it in the process of ore grinding with the reduction of 30%~40% cost and outstanding comprehensive-benefit.
