摘要: 采用三維彈塑性大變形熱力耦合有限元法,模擬薄板坯連鑄液芯鑄軋過程中的鑄坯變形,并研究液芯鑄軋時坯殼中應力應變場.分析影響坯殼中應力應交場的主要因素的基礎上,給出壓下率和坯殼厚度對應力應變場的影響規律.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.
