摘要
横向磁通感应加热技术因其连续加热金属薄板带材的优异性能一直是近年来研究的焦点.为了满足节能环保要求,提高加热系统的功率因数可加强系统能源的利用率同时降低设备的成本.基于对45 钢薄带加热需求设计了横向感应加热装置,采用有限元数值模拟的方法研究结构参数与电激励参数对横向感应加热系统功率因数的影响,并结合各参数对加热系统功率因数的影响规律对加热模型进行优化.结果表明,优化后模型与初始模型相比,系统的功率因数上升0.048,相对不均匀度下降5.15℃.优化后的模型有效地提高了系统的功率因数,并改善了带材的温度均匀性.
Abstract
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.
