摘　　要：简要介绍了结晶器电磁搅拌在福建三钢炼钢厂5#小方坯连铸机上的应用.理论分析并结合福建三钢的冶炼条件选择结晶器电磁搅拌,在长期的生产实践过程中对结晶器电磁搅拌参数进行优化,实践表明对减轻品种钢的碳偏析以及减少中心疏松和提高产品的低倍质量均有明显的效果.为进一步发挥电磁搅拌在冶金生产中的作用,提出有必要在现有的结晶器电磁搅拌的基础上增加末端电磁搅拌系统.The application of mold electromagnetic stirring in continuous casting of middle billet in the Steel Work of Sanming Iron & Steel in Fujian Province was introduced. The optimization of the operation pa-rameters of M-EMS has achieved good metallurgical results, such as decreasing the carbon segregation and pre-venting the central porosity. Those measurements are very useful in improving the quality of products. It is pro-posed that final electromagnetic stirring should be used in the end of liquid core.
