INDUCTION HEATING APPARATUS AND INDUCTION HEATING METHOD

摘要

An induction heating apparatus which continuously heats a steel plate by a solenoid system. The induction heating apparatus (1) comprises at least three heating coils (10A to 10D) which are arranged along the longitudinal direction of the steel plate such that the steel plate (2) passes through the inside thereof, and inductance adjusters (12A to 12D) which are arranged on electrical pathways (11) electrically interconnecting the respective heating coils and a power source for applying voltage to the heating coils and can generate self induction and adjust self inductance in the self induction. The inductance adjusters are arranged such that mutual induction is generated at least between mutually adjacent inductance adjusters.
