Abstract

A high frequency induction continuous heating method and a high frequency induction continuous heating apparatus are provided, and they can improve a working efficiency of a heating treatment and can also improve an uniformity of the heating treatment for an entirety of a work piece corresponding to multiple types of work pieces. In the high frequency induction continuous heating method in which a work piece (W) placed on a conveyance surface (2a) of a conveyor (2) is conveyed, and the work piece (W) on the conveyance surface (2a) is heated by high frequency induction heating coils (3) which are disposed at both ends of the conveyor (2) in a crosswise direction perpendicular to a conveyance direction (shown by an arrow (D) in the drawing), the work piece (W) is rotated around an axis which is extended so as to be perpendicular to the conveyance surface (2a), at a certain rotation angle (θ) in mid-flow of the conveyance of the work piece (W) to change an orientation of the work piece (W). The high frequency induction continuous heating apparatus (1) uses the above-described method.
