摘要
为了消除大冶钢厂圆坯表面的纵裂纹,从浸入式水口操作、结晶器相关参数以及保护渣等方面进行现场排查,最终通过缩短结晶器铜管长度,均匀热流强度,解决了圆坯纵裂问题。
In order to eliminate surface longitudinal cracks on round billets at Daye Steel,the operation of submerged entry nozzle, mold parameters and protective slag had been checked out in practice. Finally,the surfuce longitudinal cracks on round billets were eliminated by shortening the length of mold.
