Abstract
An induction heating apparatus for controlling the temperature distribution for heating a metal plate irrespective if it has a small thickness, is magnetic or nonmagnetic, and capable of coping with a change in the width of the plate, or meandering of the plate. The apparatus heats a metal plate 1 by induction heating, which passes through the inside of induction coils 2, wherein in a vertical projected image of the conductors on the metal plate 1, the conductors 2a and 2b, parts of the induction coil, placed on the front surface side and the back surface side of the metal plate 1, the conductors 2a and 2b on the front surface side and the back surface side are arranged so as to be deviated from each other in the lengthwise direction of the metal plate 1, the edge portion of at least either the conductor 2a on the front surface side of the metal plate 1 or the conductor 2b on the back surface side thereof is arranged aslant or arcuately, and magnetic cores 10 are arranged at the outer sides of the induction coils 2.
