Abstract

PURPOSE:To heat uniformly the surface of a titled shaft body with high energy conversion efficiency, by heating inductively the bulged part continuously or continuourly or intermittently for a prescribed time during heating of the shaft body by direct conduction of high frequency electric current. CONSTITUTION:When a high-frequency power source is turned on while a heating coil C is held open, high-frequency electric current flows in an arrow direction and passes through the surface layer of a shaft body W and heats by resistance the surface layer of the shaft body. Upon lapse of a prescribed time, a coil closing device is driven to press the contact pieces 211 and 221 of the coil C in an arrow Q direction so as to bring the same into contact with each other, thereby closing the coil C. The high-frequency current shown by double arrows flows from an electric power source E in such a state, then a magnetic flux is generated from the coil C and heats inductively the surface layer of a bulged part Wa facing the coil apart from a prescribed spacing. If the power source E is turned off after a prescribed time, the shaft parts Wb1, Wb2 are heated only by the direct conduction of said current and the bulged part Wa heated by the direct conduction and the induction, heating, whereby both parts are heated uniformly or at a prescribed temp. difference.
