摘　　要：文中介绍了包钢圆坯铸机采用结晶器电磁搅拌的应用效果。通过试验确定了合适的结晶器电磁搅拌的工艺参数,并通过等轴晶率、C偏析指数等指标,分析电磁搅拌对铸坯内部质量的改善作用。This paper introduces the application of M-EMS in the round caster of Baotou Steel. The rational parameters of the M-EMS are g/yen based on the industrial trails. The results show that the E-EMS obviously improves the inner quality of casting blank such as the ratio of equiaxed grain, carbon segregation, and so on.

关 键 词：圆坯铸机 电磁搅拌 铸坯质量
