Abstract
An induction heating device for a metal strip, including: an induction coil provided on one side or on both sides of a front face side or a reverse face side of a metal strip, and that induces an induction current in the strip when a primary current is passed through the coil, the induction current configuring a closed loop as viewed from a direction perpendicular to a metal strip face; plural magnetic cores disposed at a specific position, this being a position at a back face side of the coil and separated from the strip by a specific distance, to concentrate magnetic flux generated by the coil in the strip; and a moving mechanism coupled to the magnetic cores, and that moves the cores to increase or decrease a disposed number of the cores at the specific position disposed side-by-side along a metal strip width direction.
