摘　　要：借助ANSYS软件下的Fluent模块模拟了AZ31镁合金铸轧区的温度场,研究了AZ31镁合金薄带铸轧时不同工艺参数下铸轧区的三维温度场的分布,分析了温度场的分布对薄带铸轧过程稳定性的影响。通过对比分析模拟结果,给出在所选取范围内最佳工艺参数是,浇注温度为853K,铸轧速度为9m/min,冷却水流速为3m/s。The temperature field in cast-rolling area of the AZ31 magnesium alloy was simulated using the computer fluid software ANSYS Fluent,which is based on the conditions that the molten alloy of castrolling area is the same continuum,roll casting process is steady and the melt is incompressible.The three dimensional temperature field distribution of cast-rolling area of the AZ31 magnesium alloy strip cast-rolling,were investigated,with different process parameters,such as pouring temperature,roll casting speed and cooling water flow rate and effects of the temperature field distribution on the stability of strip cast-rolling process were presented.By comparing and analyzing simulation results,the optimum process in the selection range can be presented as follows：pouring temperature of 853 K,rolling casting speed of 9m/min,cooling water flow rate of 3m/s.
