摘　　要：针对AZ31镁合金,建立了铸轧过程二维直角坐标系下的热平衡方程。对浇注温度、铸轧速度、水冷强度、轧辊辊缝、轧辊辊径等采用5因素4水平的正交试验法进行了数值分析。采用ANSYS下的Fluent进行了铸轧过程温度场的模拟,讨论了镁合金带材铸轧因素对温度场的影响大小。分析结果表明,轧辊辊缝是显著性影响因素,显著性置信度为95%,其次为铸轧速度、水冷强度、轧辊辊径。Thermal equilibrium equation for rolling casting process of AZ31 magnesium alloy was established under the two-dimensional rectangular coordinate system.Considering multiple factors of rolling casting process,orthogonal method of 4 level to 5 factors was used to analyze the numerical experiment with the pouring temperature,rolling speed,water cool intensity,roll gap,roll diameter.Based on the Fluent software of ANSYS,the temperature field in rolling casting process was simulate to understand influencing sequence of rolling parameters for magnesium alloy strip and to provide reference for the presentation of optimal technological parameters.The results show that the roll gap is the significant factors,and then casting speed,water cool intensity,roll diameter.The significant confidence level is 95%.
