化スケール５を吹き飛ばす。In the scale removing device 8 having the above-described structure, the plate-like material to be heated 1 passes through the heating passage 3 of the induction heating device 4 and is induction-heated by the solenoid coil 2 to increase the overall temperature. The oxide scale 5 generated in the plate-shaped material to be heated 1 in the process of performing the induction heating falls and falls to the bottom of the tunnel-shaped heating passage 3. As described above, the oxide scale 5 accumulates. When the sensor detects that the plate-shaped material 1 has passed, the scale remover 8 uses one of the air injection nozzles 8a 1 and 8a 2 as shown in FIG. Is blown obliquely to blow off the oxide scale 5 deposited on the heating passage 3. Next, air is sent to the air injection nozzles 8b 1 and 8b 2 by the air valve switching device 17, and the air is obliquely injected from this to blow off the oxide scale 5 deposited in the heating passage 3.
