摘　　要：对重钢小方坯结晶器电磁搅拌磁场进行了测试,分析了其磁场特性,总结了磁场随电流与频率的变化规律及磁场的空间位置分布特点。并计算出工作温度下理论最佳搅拌频率为4 Hz。分析结果对结晶器电磁搅拌工艺参数优化具有指导意义。The magnetic field of in - mold electromagnetic stirrer （M - EMS） in Chongqing Iron ＆ Steel Company was measured. The magnetic field characteristic was discussed, and the relations of magnetic field and current, frequency and z direction in the mold were analyzed. The optimum frequency which was 4 Hz under working temperature was also figured out. This result could be helpful to optimize M - EMS process parameters.
