PURPOSE: To provide an induction heating equipment which realizes a small size of equipment and a maintenance free property.
CONSTITUTION: Three sets of coil units 11 are provided at the positions opposite to a part 1 which consists of a metal material in the conveying condition by a conveying device 3. A power supply device 13 to feed a high-frequency sinusoidal current to the coil units is provided. Since the part 1 is induction heated by a magnetic field generated by the coil units 11, the condition that the ambient air is heated together with the part 1 is prevented. As a result, it is not necessary to shut out perfectly the device from the outer side, and the equipment can be made in a small size. Since the surface is never deteriorated by the heat generated by the device itself, a maintenance free property can be realized. And since a trouble such as a gas leakage in a fuel gas furnace is never generated, the worker is never exposed to a dangerous condition.
