摘要：
Dynamic rolling deformation behavior of continuously cast slabs with liquid core is studied with the aid of the thermomechanically coupled finite element method (FEM) of elastic-plasticity. The effects of shell thickness and related height reduction on the longitudinal tensile strain of strand are analyzed from a simplified three-dimensional (3-D) model. The results show that the longitudinal tensile deformation can be omitted for strands with thin shell, but it cannot be neglected for those with thick shell. A new concept of inward pushing or pushing into the liquid core is put forward based on the analysis, which leads to a reasonable explanation and better understanding of the liquid core cast-rolling processes in the present Inline Strip Production (ISP) thin slab casting.
