<p>The present invention relates to a high frequency heat treatment apparatus for a track bush which is capable of improving heat treatment quality and improving productivity by reducing a heat treatment time since track bushes are transferred consecutively and horizontally while heat treatment is being performed. The high frequency heat treatment apparatus for a track bush comprises: a carrier means for horizontally laying down and transferring track bushes to be heat treated; a guide means having a rotating support part for supporting the track bushes transferred by the carrier means to be able to rotate and a pushing guide part for guiding the track bushes supported by the rotating support part by pushing the track bushes; and a heat treatment means having a high frequency induction part, which is arranged in one end of the guide means facing the pushing guide part, for penetrating and heating the track bushes guided by the pushing guide part, an outside cooling part for cooling the outer circumferential surface of the track bushes heated by the high frequency induction part, and an inside cooling part for cooling the inner circumferential surface of the track bushes heated by the high frequency induction part.</p> |
