摘要
主要分析了舞钢连铸板坯表面纵裂纹产生的原因,同时从稳定拉速、控制结晶器冷却、二冷水弱冷、浸入式水口优化、保护渣的使用和首炉纵裂控制等方面着手,制定相应的预防措施,最终减少了连铸坯表面纵裂纹的发生几率。
The article mainly analyzes the causes of longitudinal surface cracks on concast slabs in Wugang, takes appropriate preventive measures such as stablizing casting speed, controlling mould cooling, soft secondary cooling, optimizing submerged nozzle, synthetic slag application and first heat longitudinal crack control, finally reduces the frequency of longitudinal surface cracks forming on concast slab.
