<p><P>PROBLEM TO BE SOLVED: To provide a simply constituted high-frequency induction heating treatment apparatus by which respective strain-type heat-treating work parts in which a plurality of strain-type heat-treating work parts having the same shape are set on the same axis at different angles, can simultaneously be subjected to heat treatment. <P>SOLUTION: The high-frequency induction heating treatment apparatus 1 for applying the heat-treatment to the works 14, in which the plurality of strain type heat-treating work parts 13a-13d, are set at intervals in the axial direction at the different angles, respectively, on the same shaft 3, comprises heating members 4a-4d set at the circumference of the respective strain type heat-treating work parts 13a-13d and a control means 15 for controlling the heating rate of the heating members 4a-4d. Heating members 2a-2d are constituted such that the shortest distances X1-X4 from the respective strain-type heat-treating work parts 13a-13d to the heating members 2a-2d, are uniformly changed when the shaft 3 rotates. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
