本文介绍了三维有限元分析在铝合金板坯热连轧中的应用。为了评估材料的轧制行为，已采用有限元程序Abaqus/Explicit，并对热轧过程进行三维建模。测定了6063和3003铝合金热轧过程中的温度分布、流变应力变化和流变模式。并根据预测结果确定了几何形状变化和轧制力。为了验证所用模型和方程的正确性，进行了热轧实验，测量了试样的轧制力和温度，并与预测结果进行了比较。
This paper describes the application of three-dimensional finite element analysis in hot slab rolling of aluminum alloys. To assess the rolling behavior of materials, finite element program Abaqus/Explicit has been employed and the hot rolling process was modeled in three dimensions. The temperature distribution, variation of flow stress, and flow pattern were determined during hot rolling of 6063 and 3003 aluminum alloys. Also, with the aid of the predicted results the geometrical changes and the rolling forces were determined. To check the validity of the employed model and equations, hot rolling experiments were conducted and roll force and temperature of the samples have been measured and then compared with predicted results.
