A heat-treatment deviceincludes a tableon which a ring-shaped workpiece W can be placed, and a pair of heat processing unitsfor heat-processing the peripheral surface of the workpiece W. The heat-treatment deviceis used for obtaining the workpiece W having desired properties by the heat-processing the workpiece W while the pair of heat processing unitsmove in opposite directions along the peripheral surface of the workpiece W. The heat-treatment deviceis configured in such a way that a pair of revolving armsmovable relative to the tableoscillate the pair of heat processing unitsrelative to the workpiece W, thereby heat-processing the peripheral surface of the workpiece W. By adopting such a configuration, it is possible to obtain a heat-treatment device heat-processing the entire circumference of a ring-shaped workpiece.
