Abstract

PURPOSE:To heat a strip like metal uniformly in good efficiency, in heating the thin strip like metal having a narrow width by high frequency induction heating, by providing a connecting conductor contacted with both side flange parts of the strip metal. CONSTITUTION:In heating a thin strip like metal 1 having a narrow width such as a steel strip or the like by a high frequency induction method due to a heating coil 12, the strip like metal 11 is subjected to high frequency induction heating by the heating coil 12 while it is moved on contact media 13, 13 opposed thereto at a gap (g). The heating coil 12 has a circular recessed surface 12a corresponding to the outer peripheral surface of a roll 13 as well as arranged so as to oppose the recessed surface 12a thereof to the winding parts of the rolls 13, 13. By this coil, induction current generated in the both side flange parts of the strip like metal 11 is recirculated in said strip like metal 11 through a pair of rolls 13, 13. A perfect closed circuits C, C of induction current are formed by the strip like metal 11 and the rolls 13, 13 and the narrow and thin strip like metal is heated in good efficiency.
