摘要
利用ANSYS有限元软件中的电磁-热耦合技术,通过建立有限元模型,分析了多根棒材感应加热过程中,频率、电流密度、空气间隙、棒材数量、棒材的摆放位置、棒材与棒材之间的间隙对棒材的加热效果及影响规律.结果表明:增大电流密度和频率、减小空气间隙、增大棒材与棒材之间的间隙、都会提高工件在相同加热时间所达到的温度.通过控制这些参数,可以灵活控制棒材的加热速率;同时,计算值与实验值进行了比较,结果基本吻合.因而可以利用棒材的感应加热数值模拟结果为实际工艺的制定提供理论依据.
By using the electromagnetic-thermocouple coupling technology in finite element software ANSYS, the finite element model was established to analyze the effect of frequency,current density,air gap,number of bars,placement of baon the heating of the bars. The results show that with the increase of the current density and frequency , and with the increase of the gap between the bars,the temperature of all the bars at the same heating time increases. By control all those parameters,the heating rate of the bar can be flexibly controlled. At the same time,the calculated values are compared with the experimental values,and the results are basically consistent. Therefore,the numerical simulation results of induction heating of the barcan be used to provide a basis for the actual process.
