Abstract: Aiming at the impact of induction coil parameters on the heating temperature field, finite element calculation of induction heating processes under different process parameters′ levels was carried out, using ANSYS and magneticthermo coupling analysis. The impact of the induction coils shape, the distance between the induction coils and the heating surface, the width of the copper tube, and the distance between these copper tubes on the heating temperature field were studied by comparing the simulating results. And an induction heating temperature test experiment using a plate as the heated object was designed to testify the simulation results. The results indicate that the shape of induction heating temperature field is similar to the shape of the coil. The closer the coil and heating surface, the higher the heating temperature amplitude, while the distance between the coil and heating surface has little impact on the temperature field. The slenderer the copper tube and the closer the copper tubes, the higher the maximum heating temperature, and the high temperature area moves towards the edge of the plate.
