Provided is an induction heating device that suppresses excessive heating of an edge portion without a significant decrease in heating efficiency. An induction heating device for heating a thin plate-shaped item to be heated comprises a first heating coil formed substantially in the shape of a root symbol, and a second heating coil formed substantially in the shape of a root symbol and electrically connected to the first heating coil, wherein the first heating coil and the second heating coil are disposed substantially parallel to the thin plate-shaped item to be heated so as to form a first space by intersecting in the vicinity of an edge portion of the thin plate-shaped item to be heated, in a mutually electrically un-connected region, while forming a second space and a third space in regions outside the first space, where the thin plate-shaped item to be heated is not being transported, the first heating coil and / or the second heating coil being movable in a direction perpendicular to a transport direction of the thin plate-shaped item to be heated, wherein a movement of the movable heating coil causes only the first space to be increased or decreased, magnetic fluxes being generated in opposite directions in the first space and in the second and third spaces.
Description
technical field [0001] The present invention relates to an induction heating device, and more specifically relates to a thin-plate-shaped object to be heated made of a non-magnetic material or a magnetic material (hereinafter, the "thin-plate-shaped object to be heated" will be referred to as "a thin-plate-shaped object to be heated". ) is an induction heating device used for heating. Background technique [0002] Generally, when induction heating a thin-plate-shaped object to be heated of a magnetic material, heating is performed using an induction heating device including a so-called tunnel coil as a heating coil. [0003] However, in the case of inductively heating a thin plate-shaped object to be heated made of a non-magnetic material in an induction heating device including such a tunnel coil, the induced current generated on each of the front surface and the back surface of the thin plate-shaped object to be heated is suppressed. Offset, no heating can be performed. ...
