Abstract:
1. An apparatus for heating a work, comprising: a plurality of high frequency induction-heating devices, each device including: an independent pair of opposite work coils which the work passes between, an independent distance adjuster for individually and independently adjusting the distance between the work and one work coil and between the work and the other work coil without movement of the work coil in the direction of passage, and an independent output adjuster for adjusting high frequency output of the work coils, wherein the plural devices are arranged along the passage of the work from upstream to downstream, respectively, the adjacent upstream-side device and downstream-side device can be independently operated to each other, and the individual distance adjusters and output adjusters can be operated during heating to facilitate uniform heating in the direction of passage of a work.
