摘　　要：以钢厂宽厚板连铸黏结漏钢的实测样本为基础,重点考察了断面、拉速、液位等主要工艺因素对铸坯黏结的影响,统计和分析了黏结发生时的结晶器热流及其变化规律,对可能诱发黏结的浇铸参数和结晶器热流等进行了分析和探讨.Based on measured data of wide and thick slab sticking breakout in a domestic iron and steel company, the influence of slab size, casting speed and mould level on the sticking breakout was studied. The variation of mould heat flux was investigated during the sticking breakout. Some possible reasons were discussed for the sticking breakout in view of casting parameters and mould heat flux.

关 键 词：连铸 宽厚板 黏结漏钢 结晶器 热流
