在线路加热过程中,对钢板施加脉冲电磁力,使之成为一定频率的近似连续约束力。它改善了钢板在高温下加热的条件和钢的变形效率,有利于过程控制和变形精度的提高。根据电磁力辅助线路加热工艺的实际需要,介绍了电磁力辅助线路加热装置(EFALHD)的电路设计思想及分支电路的功能。通过在ANSYS中建立磁场与电路耦合模型,分析了电磁力的分布及各参数的影响规律。通过在电磁场分析的基础上增加热分析,建立了一种新的线加热有限元分析方法,以支持EFALHD的参数确定。
In the process of line heating, a pulsed electromagnetic force is added to steel plates as an approximately consecutive constrained force of certain frequency. It improves the condition of steel plates heated at high temperatures and the efficiency of steel deformation and be conducive to the control of process and the improvement for the accuracy of deformation. According to the actual needs of electromagnetic force assisted line heating process, the design ideas of circuit for the electromagnetic force assisted line heating device (EFALHD) and functions of the branch circuits are introduced. The distribution of the electromagnetic force and parameters’ influence rules are analyzed by building magnetic field and circuit coupling model in ANSYS. By adding thermal analysis on the electromagnetic field analysis, a new method of line heating finite element analysis is established to support the parameter determinations of EFALHD.
