摘　　要：本钢薄板坯连铸漏钢的主要类型是裂纹漏钢和黏结漏钢,通过对转炉冶炼与LF精炼的工艺优化,解决了钢水可浇性问题;通过新型浸入式水口的开发,结晶器保护渣性能的调整,以及开浇与浇钢过程的操作,降低了薄板坯连铸的漏钢率;漏钢率已控制在0.23%左右。There are two types of breakout at Benxi thin slab caster. One is the breakout caused by longitude crack, and the other is the breakout caused by sticking. By the optimization on converter and LF refining process, the problem of steel quality for casting is solved. Through the development of new SEN, the adjustment of physical characteristics of mould powder and the optimization of operation in the start stage and casting period, the breakout ratio of Benxi thin slab caster is controled to around 0.23 %.
