  • Induction heating apparatus and induction heating method
    Patent number: 8420990
    Abstract: There is provided an induction heating apparatus which continuously heats a steel plate using a solenoid system. The induction heating apparatus (1) includes: at least three heating coils (10A to 10D) disposed along a longitudinal direction of the steel plate to make the steel plate (2) pass through an inside thereof; and inductance adjusters (12A to 12D) disposed on electrical pathways (11) electrically connecting each of the heating coils and a power source applying a voltage to each of the heating coils and capable of generating self-induction and adjusting self-inductance in the self-induction, in which each of the inductance adjusters is disposed to cause a generation of mutual induction at least between the inductance adjusters mutually adjacent to one another.
