利用金相观察了电磁搅拌对弹簧钢６０Ｓｉ２Ｍｎ凝固组织的影响情况，并讨论了形成机制． 结果表明：在凝固过程中进行电磁搅拌，引起熔体的强烈流动，使液相区的温度场和溶质含量 趋于均匀；凝固时奥氏体的一次臂生长速度减慢，消除弹簧钢６０Ｓｉ２Ｍｎ一次结晶组织中发达的 柱状树枝晶层；而且随着搅拌功率的加大，弹簧钢一次结晶奥氏体的粒化或非枝晶化（ｎｏｎｄｅｎ一 ｄｒｉｔｅ）程度提高：电磁搅拌使弹簧钢凝固的晶核增多，一次结晶组织得到细化．
The influence of electromagnetic stirring on the solidified microstructure of spring steel 60Si2Mn was observed by metallography, and the formation mechanism was discussed. The results show that the electromagnetic stirring in the solidification process leads to the strong flow of the melt and makes the temperature field and the solute content in the liquid region tend to be uniform. The austenite primary arm growth rate slows down during solidification and the spring steel 60Si2Mn once Crystal columnar dendrite layer; and with the stirring power increases, spring steel primary austenite grain or non-degenerate (nondeno-dened) increased: electromagnetic stirring solidified spring steel Nucleus increased, a crystallization of the organization to be refined.
