摘　　要：探讨了洞穴式冲入法球化处理工艺过程中球化剂中以镁为主的球化元素的吸收率问题,通过对比冲入法中的堤坝式、凹坑式、洞穴式的形式,从反应速度的角度及生产现场的实际情况数据对比分析,得出洞穴式球化处理工艺具有球化反应稳定、球化时间长、球化元素吸收率高等积极作用,从而减少球化剂的使用量。This paper focused on the absorption rate of spheroidizing elements such as magnesium in the spheroidizing agent which was used for the flushing method of cave-in type in the process of spheroidizing treatment.Comparing the process of the dam-type,pit-type,and cave-in-type,from the perspective of reaction rate and the actual situation of the production site,it is concluded that there are more advantages in the cave type such as more stable spheroidizing reaction,longer spheroidizing time,higher spheroidizing efficiency and lower cost.As the result of the cave-in type flushing method,the use of the part spheroidizing agent was reduced.
