A technology has been developed for melting a sprayed corrosion-resistant coating during induction heating of a steel cylindrical billet with the specified coating under rotational conditions. The current frequency and other parameters of the high-frequency induction unit were chosen to ensure maximum heat release in the corrosion-resistant coating during its melting on the surface of a steel cylindrical billet. Calculations and studies of the surface distributions of the current density and temperature along the length of the billet during induction heating have been carried out. Calculation and experimental studies of induction heating, thermal and thermally stressed state of a steel billet with a coating are given. The calculated and experimental curves for heating the surface of a steel billet with a coating are compared taking into account two Curie points. An analysis of the results shows that the thermal stresses that arise in the billet do not affect the technological process of induction heating of the billet with coating melting.
