Abstract
An induction heating apparatus for heating a traveling metal plate includes an induction coil for surrounding the metal plate. The induction coil includes an upper portion for being located above the metal plate and a lower portion for being located below the metal plate. The upper and lower portions of the induction coil are spaced from each other in a longitudinal direction of the metal plate at least at one position in a transverse direction of the metal plate. The distance in the longitudinal direction of the metal plate between the upper portion and the lower portion of the induction coil varies across a transverse direction of the metal plate.
