First, the cleaning device 2 sprays a predetermined cleaning liquid onto the surface of the deck plate 1 to perform a cleaning process. The deck plate 1 that has been cleaned is then heated to a predetermined temperature by an induction heating coil 3 and dried. The deck plate 1 that has passed through the induction heating coil 3 is then coated with paint by the coating device 4.
Since the deck plate 1 is kept at a high temperature by heating by the induction heating coil 3, the paint applied to its surface is rapidly cured by the heat of the deck plate 1 itself, and the paint film is fixed.

The coated steel material to be treated is fed into an induction heating coil. Therefore, since the temperature of the steel material to be treated starts to rise from the state where the paint is applied, drying progresses and the paint film is fixed without causing the boiling phenomenon.

く定着乾燥され良質な塗膜が形成される。FIG. 2 shows the change in temperature of the steel material 11 to be treated in comparison with the conventional case. FIG. 1 (1) shows the conventional case, in which the steel material 11 to be treated is first heated by induction to raise its temperature, and then enters the coating treatment in this high temperature state. For this reason, the temperature of the paint is instantaneously raised from the room temperature state immediately before application to a high temperature, and as described above, the boiling phenomenon may occur and degassing holes may occur. On the other hand, FIG. 2 (2) shows the case of an embodiment of the present invention, in which the steel material 11 to be treated is first coated by the coating device 13, and then heated by the induction heating coil 14 to raise the temperature. In this case, the temperature increase rate is determined by the heat capacity of the steel material 11 to be treated, taking into account the electric power input for induction heating and the conveyance speed, and the temperature increases almost at a gradient as shown in the figure. Since the applied paint also increases in temperature following the temperature of the steel material 11 to be treated, a sharp temperature gradient is avoided and a high-quality paint film is formed by fixing and drying without causing problems such as boiling. be done.
