摘　　要：以跨结晶器电磁搅拌大方坯的试验数据为依据。According to the experimental investigation data of blooms by means of electromagnetic stirring across-mold,the effects are analyzed on segregation and macro structure by using and not using electromagnetic stirring.Contrasting and comparing have been done with other stirring modes.It has been confirmed by practice confirmed that the effect is remarkable to improve central segregation and increase equiaxed crystal ration by electromagnetic stirring across-mold mode.
