    • 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.
    • 提供感应加热装置和感应加热方法。 工件加热的整个区域,即使是大的工件,也可以容易且大致均匀地加热到预定的高温,并且即使在加热期间工件以不均匀的方式变形,也能够均匀地加热。 当被加热区域H1,H2被建立在工件W上以沿一个方向延伸并且待加热区域H1,H2被感应加热时,被加热区域H1,H2的一个边缘上的变形量 与另一个不同。 该感应加热装置包括:当工件W被感应加热时面向加热区域H1,H2的一部分的加热线圈451; 以及用于相对地沿着一个方向传送工件W和加热线圈451的相对传送装置,并且加热线圈451被布置成在加热期间对应于待加热区域H1,H2。
