To provide a drum-type high frequency induction hardening apparatus with which even in the case of constituting the apparatus so as to harden a large quantity of materials to be treated at one time, this hardening treatment can be performed in a narrow setting area.
The drum-type high frequency induction hardening apparatus 10 is provided with; a disk-like rotary drum 20; an induction-heating coil 30 for induction-heating a part of the material to be treated (work W); a cooling device 40 for cooling the work W heated with this induction-heating coil 30; a collecting member 50 for materials to be treated for catching and collecting the work W freely dropped from the rotary drum 20; and a driving system 60 for rotating the rotary drum 20 in the arrow-marked A direction. The rotary drum 20 rotates in the arrow-marked A direction (clockwise rotation in Fig.1) by centering a rotational shaft 24 extended to the horizontal direction, and provides a ring shape outer peripheral wall 22 forming an inserting hole 22a for inserting the work W.
