摘　　要：利用ANSYS Workbench软件对初始温度为548℃的6063铝合金铸轧板的冷却过程进行数值模拟,通过分析温度场和应力场,确定空冷至室温所需的时间及空冷时铸轧板易产生裂纹的可能位置。模拟结果表明,对于铸轧出来的6063铝合金板材,在滚道上自然冷却1800 s后接近室温状态;铸轧板实际冷却时,边部与表面中央部位易产生裂纹。Cooling process of 6063 aluminum alloy cast-rolling plate from 548 ℃was numerical simulated by using ANSYS Workbench software. The air cooling to room temperature time and easy to crack area in air cooling process were determined through analysis of the temperature field and stress field. The simulation results show that for the 6063 aluminum alloy cast-rolling plate, it needs 1800 s to the state near the room temperature at the roller bed. In the actual cooling process, the edge and the surface of central part are sensitive to cracking.
