<p><P>PROBLEM TO BE SOLVED: To provide an induction hardening method for a metallic ring by which strain and uneven hardness after hardening are smaller than before. <P>SOLUTION: When the metallic ring is induction-hardened, the hardening is performed by rotating a plurality of supporting fixtures thereby rotating the ring while applying the outward tension to the ring with the plurality of supporting fixtures so that the ring does not strain after being hardened. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
