    • An induction heating device for inductively heating an object to be heated which is formed of conductive material has a holder. The holder is positioned outside the object. The device has an exciting coil for inductively heating the object. The exciting coil is supported by the holder. The exciting coil is composed of a plurality of turns of conductor forming a layer, which is positioned along the object. The device also has a demagnetizing coil which is positioned along the layer of the exciting coil. In the demagnetizing coil, a back electromotive force is induced in accordance with a magnetic field produced by the exciting coil, so as to cancel the magnetic field. Stability in the temperature control for the object such as a heating roller can be improved by effective function of the demagnetizing coil. The device can be miniaturized and configured at low cost.
    • 用于感应加热由导电材料形成的被加热物的感应加热装置具有保持器。 支架位于物体外部。 该装置具有用于感应加热物体的励磁线圈。 励磁线圈由支架支撑。 励磁线圈由形成层的导体的多个匝组成,沿着物体定位。 该装置还具有沿着激励线圈的层定位的去磁线圈。 在去磁线圈中,根据由励磁线圈产生的磁场感应出反电动势,以抵消磁场。 可以通过退磁线圈的有效功能来提高对加热辊等物体的温度控制的稳定性。 该设备可以以低成本小型化和配置。
