摘要
针对钢板边部感应加热过程中出现的打火现象,通过数值仿真计算的方法对加热过程中引起打火的关键影响因素及其影响规律进行了系统研究。着重就钢板与线圈之间的相对位置、不同钢板宽度、负载变化等条件下,加热过程中辊道上方钢板上感应电流密度分布进行了计算和对比分析。计算结果发现,在加热窄钢板以及加热过程中钢板向感应线圈偏移一侧时更容易发生打火现象。
Concerning the phenomenon of sparking during the process of edge induction heating,the key influencing factors of sparking and their effects by numerical simulation are systematically studied. The distribution of induced current density on the steel plate above the roller table during the heating process is calculated and compared under different conditions such as the relative position between steel plate and induction coil,the width of steel plate as well as the change of load. The results show that when a narrow steel plate is heated or the steel plate is shifted to the induction coil side,the sparking phenomenon is more likely to occur.
