电磁搅拌工艺在冷轧无取向硅钢的开发及应用

Development and Application of EMS Process for Cold Rolled Non-Oriented Silicon Steel

简要介绍了太钢冷轧无取向硅钢电磁搅拌装置的工作原理及冶金效果。分析了电磁搅拌电流强度、频率等因素的影响,确定了合适的搅拌工艺参数。结果表明,电磁搅拌可以明显改善铸坯的凝固组织,冷轧硅钢铸坯等轴晶比率达到了50%以上。

This paper briefly introduces the work principle and metallurgic ef fe ct of electromagnetic stirring (EMS) equipment for cold rolled non-oriented sil icon steel of TISCO. The effects of parameters, such as current intensity and fr equency, are discussed and optimal parameters of the EMS have been obtained. The results showed that ratio of equiaxed grain in the slab of cold rolled non-ori ented silicon steel comes up to above 50 percent.
