摘　　要：为了防止出现渣铁飞溅且得到的产品会出现成分偏析而影响产品性能。笔者提出了一种新的搅拌方式-电磁搅拌,通过磁场与电场的交互作用,使钢液可控高速旋转。该方法效率高且安全。同时加入了PLC可编程控制技术自动控制变频器,极大地减少了错误,降低成本,提高效率。In order to prevent splashing of slag and iron,and the obtained product will have composition segregation and affect the product performance,a new stirring method,electromagnetic stirring is proposed,which can make the liquid steel rotate at a controllable high speed through the interaction of magnetic field and electric field.The method is efficient and safe.At the same time,PLC technology is added to automatic control frequency converter,which greatly reduces errors,cuts costs and improves efficiency.
