Design of Electromagnetic Induction Heating Based on Silver-copper Alloy Casting
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 configura-tion.By combining theoretical calculation with COMSOL software simulation,the electromagnetic and temperature physical field coupling sim-ulation 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 en-suring the quality of casting.
