摘　　要：阐述了造成连铸坯中心偏析的原因;综合论述了低过热度浇注、电磁搅拌、二次强冷、动态轻压下、结晶器喂带等连铸坯中心偏析控制技术的新进展。The causes of center segregation in continuous casting slab were expounded. The new progresses of the control technologies of the center segregation of continuous casting slab, such as low over heat casting, electromagnetic stirring, selondary forced cooling, dynamic soft reduction, mold feeding belt and so on, were synthetically discussed.

关 键 词：连铸坯 中心偏析 控制技术
