Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 5 show an embodiment of the present invention.

In the figure, the same components as those in FIG. 6 are denoted by the same reference numerals, and the description thereof will be omitted. Hereinafter, only the configuration unique to the present invention will be described.

On the exit side of the rolling mill 1, a drying chamber 11 and a suction chamber 12 are sequentially provided so as to cover the upper and lower surfaces of the rolled material 4, respectively.

Then, the rolled material 4 is placed in the drying chamber 11 in the width direction 1.
3, a reverse screw 14 extending through the screw driver 14 is connected to one end of the reverse screw 14 to which a motor 15 for adjusting the position is connected.
A pair of nut members 1 symmetrically with respect to the width center line of the rolled material 4
6, a width direction position adjusting device 17 is formed, and a microwave oscillator 18 that oscillates microwaves toward the rolled material 4 is provided on a surface of the nut member 16 on the rolled material 4 side.

On the other hand, a vapor suction machine 20 is connected to the suction chamber 12 via a suction duct 19.

Further, on the entrance side of the drying chamber 11, a moisture detecting device 22 for detecting a position where the moisture 21 adheres to the surface of the rolled material 4 is provided.

As the moisture detecting device 22, for example, a device in which a large number of light receiving elements are arranged in the width direction 13 of the rolled material 4,
A combination of a monitor camera and an image processing device is used.

Then, a moisture adhesion position detection signal 23 from the moisture detection device 22 is inputted, and the position adjustment motor 1 is inputted.
5 is provided with a control device 26 for sending a control command 24 for moving the microwave oscillator 18 to the position where the moisture 21 adheres and for sending a control command 25 for oscillating the microwave to the microwave oscillator 18.

In FIG. 4, reference numeral 27 denotes a gap formed between both ends of the upper and lower rolling rolls 2.

Next, the operation will be described.

In the rolling mill 1, the rolling material 4 is rolled by the rolling rolls 2. At this time, in order to control the temperature of the rolling rolls 2 with respect to the heat input from the rolling material 4 and the heat generated during rolling. The cooling liquid 6 is sprayed on the rolling roll 2.

As shown in FIG. 4, the cooling liquid 6 passes through the gap 27 between both ends of the upper and lower rolling rolls 2 where the rolled material 4 is not caught. In addition, the rolled material 4 mainly adheres moisture 21 to both ends.

Therefore, the moisture detecting device 22 provided on the exit side of the rolling mill 1 detects the position of the water 21 adhering to the rolled material 4 and outputs the obtained moisture adhering position detection signal 23 to the control device 26.
Send to

Then, the control device 26 controls the moisture detection device 2
2, a control command 24 is sent to the position adjusting motor 15 based on the moisture adhesion position detection signal 23, and the reverse screw 14 is driven to rotate through the nut member 16 screwed to the reverse screw 14. , Microwave oscillator 1
8 is moved symmetrically with reference to the width center line of the rolled material 4, and is moved to the position where the water 21 adheres to the rolled material 4.

When the microwave oscillator 18 is moved, the control device 26 sends a control command 25 to the microwave oscillator 18 to oscillate a microwave having a high frequency of 1000 times the high frequency toward the moisture 21.

As a result, the water 21 is heated from the inside by the principle of dielectric heating and is evaporated in a short time.

By using microwaves in this way, not only the case where hot air is used, but also the drying time is reduced to about half compared to the case where high frequency is used, and about 40% of energy saving is achieved. Is obtained.

Then, the steam evaporated from the rolled material 4 by the microwave is sucked by the steam suction machine 20 through the suction duct 19 connected to the suction chamber 12, and is discharged to the atmosphere.

It should be noted that the present invention is not limited to only the above-described embodiment, and that one microwave oscillator or three or more microwave oscillators may be provided. The direction and position adjustment device is not limited to the combination of the reverse screw and the position adjustment motor.The moisture detection device may be something other than a device using a light receiving element or a monitor camera.The moisture removal device is directly connected to the rolling mill. Needless to say, it may be installed at a place remote from the rolling mill in the line, and it is needless to say that various changes can be made without departing from the gist of the present invention.
