连铸坯的宏观偏析主要包括中心偏析和带状偏析。应用电磁搅拌,可以改善连铸坯的中心偏析,但同时又伴有带状偏析的产生。在经搅拌以后的铸锭与搅拌位置对应处出现一负偏析带,即“白亮带”。本文就电磁搅拌改善连铸坯中心偏析的机理进行了试验研究。提出了应用电磁搅拌改善中心偏析的途径及具 Macro-segregation of slab mainly includes center segregation and band segregation. Application of electromagnetic stirring can improve the central segregation of slab, but at the same time accompanied by ribbon segregation. After stirring the ingot and mixing position corresponding to a negative segregation zone, the “white with bright.” In this paper, electromagnetic stirring to improve the center of the segregation mechanism of the billet were studied. Proposed ways and means of using electromagnetic stirring to improve center segregation
