Abstract

To optimize the shape and parameters and to increase efficiency of induction heating furnace, detailed simulation of its electromagnetic behavior is needed. Due to the complexity of the model, a special 3D edge finite element method (EFEM) with vector potential formulation and extended use of radial and axial symmetry was developed, enabling sufficient analysis based only upon a small slice of the model. We analyzed several models with different coil positions, number and position of cold crucibles and air-gap widths. Also, different values of frequency and intensity of the source current were considered in order to determine their influence over eddy-current losses and levitation force acting on the molten metal. In this paper the method of analysis, models and obtained results, which agree well with measured results are presented.
