摘　　要：用数值模拟方法研究了特厚板坯在弯曲矫直区的温度与机型的关系。研究结果表明,垂弯带液芯矫直型连铸机有利于防止铸坯表面裂纹。本研究成果对选择适宜的特厚板坯连铸机型具有一定意义。The relationship between the temperature of the Extra-thick slab in bending and straightening zone and the caster type is studied by numerical simulation method. Results suggest that vertical bending type caster with liquid core during straightening can help to inhinit the surface crack of the slab. The research on the appropriate choice of extra--thick slab caster type has certain significance.
