摘要： An induction heating device and an induction heating method are provided. The entire areas to be heated of the workpiece can be uniformly heated to a predetermined high temperature, and uniform heating is possible even when the workpiece deforms in a non-uniform manner during heating. When areas to be heated are established on a workpiece so as to extend in one direction and the areas to be heated are induction-heated, the deformation amount on one edge of the areas to be heated is different from that on the other. This induction heating device includes: heating coils facing a portion of the areas to be heated when the workpiece is induction-heated; and a relative transfer means for transferring the workpiece and the heating coils along one direction in a relative manner, and the heating coils are disposed so as to correspond to the areas to be heated during the heating period.

摘要： An induction heating device and an induction heating method are provided. The entire areas to be heated of the workpiece, even a large workpiece, can be readily and approximately uniformly heated to a predetermined high temperature, and uniform heating is possible even when the workpiece deforms in a non-uniform manner during heating. When areas to be heated H1, H2 are established on a workpiece W so as to extend in one direction and the areas to be heated H1, H2 are induction-heated, the deformation amount on one edge of the areas to be heated H1, H2 is different from that on the other. This induction heating device includes: heating coils 451 facing a portion of the areas to be heated H1, H2 when the workpiece W is induction-heated; and a relative transfer means for transferring the workpiece W and the heating coils 451 along one direction in a relative manner, and the heating coils 451 are disposed so as to correspond to the areas to be heated H1, H2 during the heating period.

摘要： 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.
