Abstract
Official abstract text for this publication.
A heating apparatus, a heat treatment apparatus, and a heating method are provided. The heating apparatus includes a workpiece support on which a ring-shaped workpiece is placed, a rotary drive assembly, and a heater configured to heat the workpiece. The workpiece support includes a plurality of rotating rollers arranged in a circumferential direction. The rotary drive assembly is configured to rotate the plurality of rotating rollers to rotate the workpiece placed on the workpiece support along a ring shape of the workpiece. The heater includes a heating coil configured to induction-heat the workpiece on the workpiece support at a heating position, and an actuator configured to move the heating coil at the heating position relative to the workpiece to adjust a distance between the workpiece and the heating coil.
First claim
Opening claim text (preview).
1 - 13 . (canceled) 14 . A heating method comprising: placing a ring-shaped workpiece on a plurality of rotating rollers arranged in a circumferential direction; setting the workpiece at a heating position to face a heating coil; moving the heating coil to adjust a position of the heating coil relative to the workpiece; rotating the rotating rollers to rotate the workpiece along a ring shape of the workpiece; and induction-heating the workpiece. 15 . The heating method according to claim 14 , wherein the rotating rollers are connected to a central structure unit and arranged in the circumferential direction around the central structure unit, and the workpiece is placed on the rotating rollers such that the workpiece surrounds the central structure unit, the method further comprising: after the placing is carried out in a loading section, conveying the workpiece together with the rotating rollers from the loading section to a heating section, in which the heating coil is provided, such that central structure unit is suspended.
