<p><P>PROBLEM TO BE SOLVED: To provide a heat treatment method by means of an induction heating which is high in productivity. <P>SOLUTION: The method for heat treatment of the present invention relates to a method for executing the heat treatment of a metallic plate-like workpiece 32. The plate-like workpiece 32 has a through- hole, and is capable of forming a current path around the circumference of the through-hole. The method for heat treatment includes: a layering step of layering a plurality of workpieces 32 so that the positions of the through-holes are matched with each other; and a heating step of inducing the current in the current path of each workpiece 32 and heating the workpieces 32 by generating the alternating magnetic flux in a core 30 installed so as to pass each through-hole of the plurality of layered workpieces 32. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
