【摘要】 对镀锌生产线上连续运动的薄钢板的横向磁通感应加热过程应用了三维有限元分析。所采用的数学模型包含一组稳态涡流问题的偏微分方程和含运动媒质的傅立叶热传导方程,对涡流场和与之相耦合的温度场进行了计算。为了提高计算效率,对问题的简化和边界条件的处理进行了分析。为了使薄板表面的温度均匀分布,应用正交试验法对感应加热器的结构进行了优化。更多还原

【Abstract】 In this paper the 3 dimensional finite element analysis for transverse flux induction heating (TFIH) of continuously moving thin steel strip for galvanizing line are presented. The adopted mathematical model consists of a set of differential equations for the steady-state eddy current problem and a Fourier’s thermal conduction equation for moving media. The eddy current field and its coupled thermal field are computed. The simplifications and boundary conditions required for an efficient solution are discussed. To achieve a completely uniform temperature distribution on the thin strip surface, orthogonal experiment is used for optimizing the heater structure.更多还原
