摘　　要：针对国内某钢厂连铸生产过程中的漏钢事故,分析了连铸板坯产生漏钢的原因。认为铸坯表面凹陷、保护渣性能不良、液面波动和操作不当是引起粘结漏钢的关键,并分析了液面波动和"重浇"产生的原因。By studying a breakout accident in slab continuous casting at a domestic steel plant, the paper analyzes reasons for the accident. It believed that debosses on casting billet surface, poor performance of covering slag, fluctuation of liquid level and improper operation are key reasons for causing sticking breakout. The paper also analyzes causes for liquid level fluctuation and recast.

关 键 词：板坯连铸 漏钢 凹陷 保护渣 液面波动
