摘要: 采用彈塑性大變形熱力耦合有限元法研究了鋼板熱軋過程,側重計算軋件厚向溫度分布,并分析了熱傳導模型、軋輥溫度變化對計算結果的影響.計算結果與實驗結果比較符合.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.
