摘　　要：测定板坯连铸机二冷区凝固坯壳厚度,得出了特定工艺条件下的凝固系数和液芯长度,为板坯高质量生产提供了重要依据,解决铸坯内部中心偏析、疏松等缺陷。By measuring the solidified shell thickness in the secondary cooling zone of slab CCM,the solidification coefficient and the liquid core length of specific processing conditions were calculated,which provided an important basis for improving the slab quality and reduced central segregation and porosity.
