| Abstract: | 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. |

| Keywords: | thin slab continuous casting cast-rolling stress and strain distribution |
