Research and Optimization of Power Factor of Transverse Induction Heating Device
Transverse flux induction heating technology has been the focus of research in recent years because of its excellent performance in continuously heating thin metal sheets and strips.In order to meet the requirements of energy saving and environmental protection,increasing the power factor of the heating system can enhance the utilization rate of the system energy and reduce the cost of the equipment.A transverse induction heating device was designed based on the heating requirements of 45 steel thin strip.The finite element numerical simulation method was used to study the influence of structural parameters and electrical excitation parameters on the power factor of the transverse induction heating system,and the initial model was optimized by combining the influence of each parameter on the power factor of the heating system.The simulation results show that,after the optimized model,the power factor of the system is increased by 0.048 compared with that of the initial model,and the relative unevenness of the optimized model is decreased by 5.15℃.The optimized model effectively improves the power factor of the system and improves the temperature uniformity of the strip.
