摘要
采用三维弹塑性大变形热力耦合有限元法，模拟薄板坯连铸液芯铸轧过程中的铸坯变形，并研究液芯铸轧时坯壳中应力应变场．分析影响坯壳中应力应交场的主要因素的基础上，给出压下率和坯壳厚度对应力应变场的影响规律．
Rolling characteristics of continuously cast slabs with liquid core is studied with the aid of elastic-plastic and thermal-mechanical coupled FEM. The effects of shell thickness and related heigh reduction on stress and strain distribution are analyzed during cast-rolling with liquid core in thin slab continuous casting.The stress and strain of the shell increase with increasing shell thickness for the sarne related heigh reduction.The strain of the shell increases with increasing related heigh reduction for the same shell thickness.
