摘要：
In an induction heating apparatus including a heat resistant heat insulating board disposed inside of an induction heating coil for shielding the radiant heat from a heated material which passes through the inside of the induction heating coil in which the to-be-heated material is heated by an alternate magnetic field applied by the induction heating coil, scales formed on the surface of the heated material and falling onto the heat insulating board are stably blown off from the heat insulating board by injecting a gas at at least two different injection angles to the heat insulating board from at lest one of the inlet end and the outlet end of the induction heating coil.
