铝合金熔炼在铝合金铸造过程中是非常重要的环节,其质量决定了铝合金铸件的性能。研究铝合金熔炼过程传热行为可以更好地帮助控制熔炼过程参数,得到质量更优的铝合金熔体。对铝合金感应熔炼过程电磁场与温度场耦合数学建模,基于有限差分法进行数值求解,并通过自编程序得到铝合金感应熔炼过程三维熔体传热行为结果。另外分析讨论了不同电磁参数对铝合金感应熔炼熔体传热行为的影响。
Aluminum alloy smelting in the aluminum alloy casting process is a very important part of its quality determines the performance of aluminum alloy castings. Studying the heat transfer behavior in the aluminum alloy smelting process can better help to control the smelting process parameters and obtain the better quality aluminum alloy melt. The mathematical modeling of electromagnetic field and temperature field coupling in the process of induction melting of aluminum alloy was numerically solved based on the finite difference method. The results of the heat transfer behavior of the three-dimensional melt during the induction melting process of aluminum alloy were obtained by self-programming. In addition, the influence of different electromagnetic parameters on the heat transfer behavior of aluminum alloy melt is analyzed and discussed.
