する。[Detailed description of the invention] [Technical field to which the invention pertains] This invention is a baking treatment in which when a thin steel plate to which a coating liquid is applied passes through a heating coil, the steel plate is heated to evaporate the solvent in the coating liquid. The present invention relates to an induction heating device that performs heating.

As shown in FIG. 3, the conventional coil shape for this type of induction heating device has a gap between the conductors of the coil 2 to release steam 4 generated when the thin steel plate 1 is heated to the outside of the coil. I have secured it.

みならず品質の不良を生じることがある。 However, as shown in Figure 4, the cross section of the coil shows that cooling water 3 is flowed into the hollow part of the coil conductor 2a in order to cool down the self-heating of the coil conductor 2a, and an insulating layer is used to protect the conductive part from insulation. 2b, but when the steam 4 passes through the gap between the coil conductors, it forms a dew point on the surface of the insulating layer 2b, becomes water droplets 5, and drips onto the top surface of the thin steel sheet 1, reducing only the appearance of the thin steel sheet. This may result in poor quality.

ための大きな障害となつていた。 Therefore, for example, the utility model application was published in 175395 (Sho 57-175395).
In the publication, a U-shaped groove is provided as a measure against dripping of steam. However, this method has a complicated structure and the cross section of the current-carrying part of the coil conductor is small by the gap, which has been a major obstacle to improving electrical efficiency.

This invention improves electrical efficiency by eliminating gaps between the coil conductors, and also forcibly releases steam generated from the thin steel plate to the outside of the coil, thereby achieving high electrical efficiency and induction without causing defects in the product steel plate. The purpose is to provide a heating device.

In order to maximize the cross-sectional area of the current-carrying part of the heating coil, the steam generated from the thin steel plate is forced to the outside of the coil through a ventilation duct installed in the coil, so that the conductors can be tightly wound by eliminating gaps between the conductors. It is intended to be released.

FIG. 1 is a cross-sectional perspective view showing an embodiment of the present invention, in which a heating coil 2 is tightly wound, a ventilation duct 12 is disposed inside this coil, and a coating liquid is applied inside this ventilation duct. A thin steel plate 1 passes through.
Intake air 13a is forced into the ventilation duct 12 via the connection duct 11 from the ventilation fan 10, and is discharged into the atmosphere as exhaust air 13b containing steam. A slit 14 is provided at the other end of the ventilation duct 12 to allow the thin steel plate 1 to pass through, thereby preventing leakage of the intake air 13a. FIG. 2 is a projection view of the device according to the present invention seen from the air discharge side, and the coil whose conductor hollow part is water-cooled is connected to the connecting terminal 8 from the AC power source 9.
Then, the power is turned on through the drawer part 2c, and the thin steel plate 1
heat up. The ventilation duct 12 is made of a non-magnetic, non-conductive material (for example, an airless insulator), and its ceiling is sloped as shown in Figure 2, so in the unlikely event that the ceiling inside the duct Even if water droplets are generated, surface tension causes them to travel along the ceiling plate and reach the side panels (vertical portions) without directly dropping onto the top surface of the thin steel plate 1.

Furthermore, if a suitable thermally insulating material is used for the ventilation duct 12, the ventilation duct 12 can be brought into contact with the inside of the coil 2, and the space inside the ventilation duct can be used effectively, and the dimensions of the coil 2 can be reduced.

According to this invention, a ventilation duct that surrounds the thin steel plate is provided inside the heating coil, and by forcing air between the ducts, the solvent vapor generated from the thin steel plate is forced to the outside of the duct, and the vapor reaches its dew point. Since it is released into the atmosphere without being tied, the quality of the product surface is maintained without the vapor liquefying and dripping onto the surface of the thin steel sheet. In addition, this duct allows the solvent vapor to flow outside the duct, i.e. through the coil opening (steel plate entrance/exit).
Since the energy is discharged using the energy, it is not necessary to provide a ventilation gap between the coil conductors, and as a result, the coil can be tightly wound and the cross-sectional area of the current-carrying part can be expanded, so that high electrical efficiency can be obtained. Furthermore, since the coil does not come into contact with steam, the coil insulation will not be damaged by exposure to vapors such as organic solvents, resulting in a long service life, and the ventilation duct has a heat retention effect, improving thermal efficiency.
