Metal plates are taught. Fig. 9 is a schematic view showing a heating portion and a temperature characteristic of a conventional induction heating device. Fig. 9a is a plan view of a heating portion of a conventional inductive device as viewed from the upper side. Head 9b and Fig. 9e are the front and right side views, respectively. In Fig. 9a, the primary coil 2, which is a heating coil, is connected, and the filament is on the magnetic core 3. The panel 4 is disposed on the upper side of the coil 2 and the magnetic core 3, and is moved in the direction of the arrow symbol and processed. Fig. 9d is a temperature characteristic diagram of the temperature of the heated metal plate. In Fig. 9d, when the metal plate is a non-magnetic body, as shown by the solid line, the temperature of the two ends of the metal plate rises, and the portion σ of the inner side of the metal plate is in the case where the metal plate is a magnetic body, although the metal The two d's of the plate are ascending 'but as shown by the dotted line, it is not produced - the kind of non-magnetic body == Wang's current temperature drop phenomenon. Usually, whether it is a metal plate of a magnetic body or a metal plate of a non-magnetic body, an eddy current is generated when the magnetic flux passes through the metal plate. As a result, 5 22203pifl Correction date: July 28, 1999 is the Chinese manual of No. 95139M6. There is no scribe correction. In the macroscopic view, the current is distributed in a state where an induced current concentrates on the peripheral portion of the metal plate. Therefore, as shown in Fig. 9d, the temperatures of both ends of the metal plate rise. However, when the induced current is concentrated at the end, the induced magnetic field generated by the concentrated current can eliminate the magnetic flux of the primary coil 2, causing the temperature of the portion of the innermost portion to be lower. It was confirmed that the temperature rise phenomenon occurred in l〇mm# at both ends of the metal plate, and the temperature drop phenomenon occurred in the vicinity of 50 mm from the both ends to the inner side. Patent Document i describes a method of joining steel sheets in the inter-heat rolling, in order to set the temperature of the corner portions of the steel sheets to be joined to be equal to the temperature of the steel sheets to be joined except for the corner portions. On the other hand, the constituent members of the electric raft are disposed directly above the butted steel sheet to generate a diamagnetic field.

Fig. 5 is a schematic view showing a heating portion of an induction heating device formed by a lateral mode according to a fifth embodiment of the present invention. Fig. 5a is a plan view of the heating portion of the induction heating device of the present invention as seen from the upper side. Figure 5b and Figure are the front and right side views of the parent. In Fig. 5b, the primary coil 2 is connected to the induction heating power source i and mounted on the upper and lower magnetic cores 3. The second, 'and the coil 5 are disposed between the metal plate 4 and the primary coil 2, respectively. Fig. 6 is a view showing a secondary coil connection diagram of a different connection method of the secondary coil of Fig. 5. In 1囷6a, the secondary coils facing up and down are connected to each other. In Fig. 6b, the direction in which the current is connected to the secondary coil in the above direction is the same direction. The sensing device formed in the lateral direction shown in FIG. 5 and FIG. 6 can be made the same as the description tool of FIG. 1 to FIG. 3 by using the element heat of the secondary coil described above. The hot portion t of the temperature characteristic is not the coil 2 of the induction heating device of the sixth embodiment of the present invention. Since the primary and secondary cut coils 5 connected to the induction heating power source 1 do not have a magnetic core, f 5 of the primary coil 2 industry environment can be disposed in the same plane. These coils are suitable for applications where the specific conditions of the set temperature and the set temperature are not used, and the compactness of the device is pursued. The arrangement of the induction heating device according to the seventh embodiment of the present invention is not shown. In Fig. 8, the induction heating power supply small primary coil 2, the magnetic core 12 1333395 22203ρίΩ is the 95139146 Chinese manual without a slash correction. This correction date: July 28曰3, metal plate 4 and secondary line _ configuration, The same as the connection _. Further, the secondary coil 5 is fixed to the moving gear % gear 74 and connected to the motor 73. The sensor 72 and the motor 73 that are moved in the secondary coil are connected to the control unit w. In FIG. 8, the data of the change in the width of the metal plate 4, the thick body, and the like are set in the control unit 71, and The W ^ is a suitable winding mode and shape of the secondary coil 5. The second control unit 71 drives the motor according to the data: break = feed = need to apply the heart I Lin T in the description of Fig. 4 The heat treatment with better accuracy is carried out in succession. Effective == == Inductive heating device of the invention can be raised and: two bundles, the temperature plate on the part of the metal plate is also OK (four) 'Even in different shapes of metal 嗖 rate ri Replacing the secondary coil 'so that the utilization of the device can be improved> + 'and the species maintains a uniform temperature score. Although the present invention has been disclosed in the preferred embodiment as above, the skilled person is not out of this section.
