摘　　要：文章通过研究电磁搅拌对小方坯SWRCH35K钢铸坯内部质量的影响,确定小方坯铸机生产中、高碳钢种时,采用电磁搅拌工艺可以改善连铸坯的中心裂纹、扩大中心等轴晶区面积、均匀铸坯中碳成分。采用电磁搅拌工艺后,小方坯铸坯质量得到明显提高。In the paper,with the research of how electromagnetic stirring could influence internal qualities of billet SWRCH35K,it is got when producing high-medium carbon steel with chamber machine,electromagnetic stirring could improve center burst of continuously cast bloom,enlarge area of equiaxed crystal zone,and even content of carbon in billets. After adopt the technology of electromagnetic stirring,quality of billets is improved obviously.
