| 摘 要： | 采用弹塑性大变形热力耦合有限元法,模拟薄板坯 铸液芯铸轧过程中的坯壳变形,指出液芯铸轧台阶段坯壳较薄时铸坯纵向伸长可以忽略,但铸轧后期坯壳较厚时铸坯纵向伸长不能忽略。分析影响铸坯纵向伸长的主要因素,给出铸坯纵向塑性应变与坯壳厚度和压下率的关系。

| Abstract: | Rolling characteristics of continuous cast slabs with liquid core is studied with the aid of elastic-plastic and thermal-mechanical coupled FEM. The studies show that the longitudinal tensile strain of strand can be ignored for thin shell,but it can not be ignored for thick shell.The effects of shell thickness and related height reduction on the longitudinal tensile strain of strand are analyzed. |

| Keywords: | thin slab casting cast-rolling longitudinal tensile strain |
