铁磁金属粉末粘结磁通集中器（MPB-MFC）感应加热在金属表面热处理中显示出更多优势。然而，移动加热的应用大多应用于工业生产中。因此，对移动感应加热过程的机理、效率和可控性的分析理解对于过程设计和优化是必要的。研究了移动式聚磁感应加热的机理。通过建立有限元仿真模型，对MPB-MFC辅助Inconel 718合金移动感应加热进行了研究。分析了温度场的分布，研究了影响温度的因素。结果表明，工件的速度应适当控制，传热系数（HTC）的温度发展的影响不大，相比其他输入参数。此外，通过对AISI 1045钢的有限元模拟与实验结果的比较，验证了静态数值模型的有效性。所建立的数值模型可以为生产过程控制提供全面的认识。
The induction heating with ferromagnetic metal powder bonded magnetic flux concentrator (MPB-MFC) demonstrates more advantages in surface heating treatments of metal. However, the moving heating application is mostly applied in the industrial production. Therefore, the analytical understanding of the mechanism, efficiency, and controllability of the moving induction heating process becomes necessary for process design and optimization. This paper studies the mechanism of the moving induction heating with magnetic flux concentrator. The MPB-MFC assisted moving induction heating for Inconel 718 alloy is studied by establishing the finite element simulation model. The temperature field distribution is analyzed, and the factors influencing the temperature are studied. The conclusion demonstrates that the velocity of the workpiece should be controlled properly and the heat transfer coefficient (HTC) has little impact on the temperature development, compared with other input parameters. In addition, the validity of the static numerical model is verified by comparing the finite element simulation with experimental results on AISI 1045 steel. The numerical model established in this work can provide comprehensive understanding for the process control in production.
