摘　　要：为了解决箱体凝固过程出现球化级别低问题,对影响球化率的原因进行分析,对箱体铸造工艺、合金熔炼工艺、球化处理和孕育工艺进行了完善,最终解决了箱体球化级别低的难题,箱体球化率普遍达到了85%以上,箱体生产取得了较好的经济效益。In allusion to the problems of spheroidization degradating and graphite distortion of pallet car frame castings in solidification process, the causes affecting spheroidizing rate were analyzed, the casting process, smelting process, ball treatment and inoculation process for pallet car frame castings were improved, and finally the problem of low spheroidizing rate was solved, spheroidization rate generally reached more than 85%.
