提出一种用以解决连铸板坯角横裂纹缺陷的倒角结晶器技术。倒角结晶器的数值仿真和工业化试验表明：倒角铸坯在连铸矫直区角部温度可以提高70℃以上，能够避开钢的高温低塑性区；同时，倒角的特殊的结构形式可以降低铸坯角部的Z向应力，有助于控制角横裂纹缺陷。
A chamfering mold technology was brought forward to remove the transverse corner crack of continuous casting slab. Numerical simulation and industrial experiment of chamfering mold show that the corner temperature of chamfered slab can be increased more than 70℃ at straightening section, which escape the high temperature inductile zone of steel. At the same time, the structure of bevel edge can decrease the Z-direction stress of continuous casting slab to control the transverse corner crack.
