摘　　要：金属加热温度的范围直接影响铸造成型的质量,感应加热电源的输出功率过低将导致加热金属温度达不到熔点,而过高的温度会导致金属过烧使其力学性能恶化;工件加热效果取决于感应加热电源的配置和感应器的工艺设计,传统设计多以理论经验公式来计算电源的功率、频率和感应器匝数范围,因工件工艺材质存在差异,实验效果与理论计算结果存在较大偏差,从而需要大量实验去调整感应器规格和电源配置。通过将理论计算与COMSOL软件仿真相结合的方式,利用电磁-温度物理场耦合模拟实验,从而确定最优电源的参数配置,完成感应器设计,现场运行情况符合仿真结果,避免了大量实验优化,有效缩短了设计周期,保证铸造质量。The range of metal heating temperature directly affects the quality of casting,the output power of induction heating power supply is too low will lead to heating metal temperature can not reach the melting point,and too high temperature will lead to metal over-burning and its mechanical properties deterioration;The workpiece heating effect depends on the configuration of the induction heating power supply and the process design of the sensor.The traditional design mostly uses the theoretical empirical formula to calculate the power supply,frequency and the sensor turn range.Due to the differences in the workpiece process materials,there is a large deviation between the experimental effect and the theoretical calculation results,so a large number of experiments are needed to adjust the sensor specifications and power supply configuration.By combining theoretical calculation with COMSOL software simulation,the electromagnetic and temperature physical field coupling simulation experiment is used to determine the optimal power supply parameter configuration and complete the sensor design.The field operation is consistent with the simulation results,avoiding a large number of experimental optimization,effectively shortening the design cycle,and ensuring the quality of casting.
