Heating apparatus and heating stabilization device in thereof

摘要

A heating apparatus includes a steel belt conveyer having a steel belt with a top part that transports and heats, and induction heating coils having an elliptical or a rectangular shape disposed under or over the top part of the steel belt such that the longitudinal direction of each of the induction heating coils forms an angle of 45° to 135° inclusive with the moving direction of the steel belt. A heating stabilization device can be used in such an apparatus. The heating stabilization device has one or a plurality of rollers that are brought into contact with the top surface of the top part of the steel belt so that the top part of the steel belt is prevented from rising during a heating operation.
