In this paper, a novel method based on electromagnetic heating theory is introduced to achieve a stable and uniform temperature distribution on the target surface of the hot-plate. The heat process of hot-plate is divided into two stages. At first, the thin layer of S45C was coated on the surface of the hot-plate by thermal spraying. Due to skin effect, coated S45C layer can be considered as heat source in terms of the law of electromagnetic heating. Secondly, the hot-plate made of pure aluminium with a high thermal conductivity can be employed to reduce the temperature difference. Finally, the target surface temperature of the hot-plate is stabilized at specific temperature by changing the holding current.
