摘要: 采用弹塑性大变形热力耦合有限元法研究了钢板热轧过程,侧重计算轧件厚向温度分布,并分析了热传导模型、轧辊温度变化对计算结果的影响.计算结果与实验结果比较符合.

Abstract: The hot rolling of steel plate was studied with the aid of elastic-plastic and thermal-mechanical coupled FEM, particular attention was paid to predict the tempera-ture distribution through the thickness of rolled plate. The influences of heat transfer model and variation of roll temperature on calculated result were analyzed. Comparison of the calculated results with those from experiment showed good agreement.
