摘　　要：通过对钢球进行失效分析,选定适合生产钢球的圆钢坯料,研发了采用电感应加热、高效利用及余热连续淬火的滚锻成形生产工艺,保证了钢球形成新的再结晶组织,钢球经连续淬火及回火工艺,进一步提高了其耐磨性和抗冲击性;该生产过程自动化程度高,工艺参数控制稳定、产品质量稳定且技术经济指标好。钢球在φ8.8 m磨机中的应用单耗为0.546 kg/t,在提高磨矿效率的同时,有效降低了磨矿生产成本。After the failure analysis of the steel ball, the round steel billet suitable for forging of the steel ball was determined. In addition, the rolling and forging process involved electric induction heating and continuous quenching by using waste heat was developed. It guaranteed the formation of newly recrystallized microstructure in the steel ball, and the wear resistance and the impact resistance property were enhanced after continuous quenching and tempering. The production was characterized by high automation level, stable control parameters, uniform product quality and excellent technical and economic indexes. The specific energy consumption of the steel ball in φ8.8 m was 0.546 kg/t, thus the grinding efficiency increased and the grinding cost effectively decreased.
