摘　　要：以40 t铝材退火炉内铝卷为研究对象,分析铝卷的传热过程,拟合出对流换热系数对温度的数学表达式,并利用黄金分割法间接求得铝卷径向导热系数,从而建立铝卷的传热数值模型。采用ANSYS分析软件对铝卷温度场进行数值模拟,仿真结果与实测温度值基本吻合,证明所建模型的正确性,为铝卷退火工艺的优化提供了理论基础。Based on annealing furnace with 40t aluminum coil, the heat transfer is analysized, the expression of the convectave coefficient to the temperature is derived, and the radial thermal conductivity of the aluminum coil has been resolved indirectly applying the golden section method, thus a numerical model for the aluminum coil＇s annealing temperature field is established. The temperature field of the aluminum is simulated using the finite element analysis software of ANSYS. The result shows that the simulation temperature at the test point is consistent with the measurement temperature, it proves that the numerical model is reasonable, and provides the theory basis for improving the annealing process.
