将同位网格引入熔炼模拟,在对感应电炉物理模型进行简化的基础上,建立描述其物理过程的数学模型,进行了感应加热温度场的数值模拟;同时采用有限体积法求解机械搅拌过程中的流动场,分析了金属熔体在搅拌过程中流动行为的特点和温度分布。模拟结果表明,感应熔炼从四周边缘开始熔化,熔化结束后存在热节点,而机械搅拌能大大加速温度均匀化过程。
Based on the simplification of the physical model of induction furnace, a mathematical model describing its physical process was established and the temperature field of induction heating was numerically simulated. At the same time, finite volume method was used to solve the problem of mechanical stirring process Flow field, the characteristics and temperature distribution of the metal melt flow behavior during the mixing process were analyzed. The simulation results show that the induction melting begins to melt from the periphery, and there is a thermal node after the melting, and the mechanical stirring can greatly accelerate the temperature homogenization process.
