摘　　要：结合东北特殊钢集团大连特殊钢有限责任公司连铸机的实际生产状况，在不同结晶器电磁搅拌强度下，对SUS416易切不锈钢铸坯质量的影响进行了试验分析。试验结果表明：结晶器电磁搅拌强度为200A／5Hz时，能够降低钢中氧含量，皮下气孔以及卷渣数量得以大幅度减少，同时明显改善铸坯中心缩孔程度。The paper briefly introduces the actual production condition of the Dongbei special steel group Dalian Base continuous caster, and analyses the effects of the different mould electromagnetism stirring（M-EMS） strength to the quality of the free cutting stainless steel SUS416. The test results indicate that when the strength of M-EMS is 200A/SHz, the oxygen content in steel, the hypodermic blowhole and slag inclusion quantity are reduced substantially, with obviously improving the level of billet centre shrinkage
