摘　　要：电磁力影响金属熔体中非金属夹杂物的分布及颗粒的传输速度,根据这一原理,进行了结晶器电磁搅拌对方坯中非金属夹杂物去除影响的试验研究。采用200、250 A和300 A这3种不同的EMS电流对方坯坯料进行了夹杂物分离和去除的试验,并采集样品进行能谱分析。结果表明,当结晶器的电磁搅拌参数为300 A电流和3 Hz频率时,铸坯中的非金属夹杂物控制效果最佳,比不采用电磁搅拌减少了35%。Based on the principle that electromagnetic force affects the distribution of non-metallic inclusions and the velocity of particles in molten metal,the effect of electromagnetic stirring in mold on the removal of non-metallic inclusions in billet was studied.The inclusion separation and removal experiments were carried out by using EMS current of 200,250 and 300 A,and the samples were collected for energy spectrum analysis.The results show that the best control effect of non-metallic inclusion in the billet is obtained when the electromagnetic stirring parameters of the mold are 300 A current and 3 Hz frequency,which is 35%less than that without electromagnetic stirring.
