The invention provides an induction heating system and method of using it for heating a metal plate. The induction coil of the induction heating system includes sections each having conductors at front and back surfaces of the metal plate, which are arranged such that at least a one of the front or back surface conductor has a part slanted in the width direction of the metal plate, and vertical projections of the conductors onto the metal plate do not overlap at the center of the metal plate but overlap outside the edges of the metal plate. In addition, front conductors from adjacent sections are spaced differently as back conductors. The induction heating system allows for better control of the heating temperature distribution regardless of the metal plates thickness and magnetic properties, especially temperature distributions at the edges of the metal plate.
