Abstract

PURPOSE: To eliminate the fluttering and vibrating of a metallic strip by arranging high-pressure water spraying nozzles in positions facing backup rolls across the metallic strip. CONSTITUTION: The metallic strip 1 is progressed between the backup roll 2a and the high-pressure water spraying nozzle 3a arranged to face each other, by which the rear surface of the metallic strip 1 is washed with the high- pressure water. In succession, the metallic strip is progressed between the backup roll 2b and the high-pressure water spraying nozzle 3b arranged to face each other, by which the front surface of the metallic strip 1 is washed with the high-pressure water. While this device is not always limited to the case the backup rolls are used, the device may also be used for a scrubber tank or rinsing tank for which spraying of general cleaning sections is used. As a result, dealing with a smaller space and higher-speed passing material in addition to the decreasing of the pump driving power by the lowered pressure of spraying is made possible.

り、Ｙはばたつき振動の振幅を示している。The high pressure water spray cleaning is applied to the front and back surfaces of the running metal strip 1 with a certain tension as shown in FIG. In this case, high-pressure water is sprayed from the front and back at exactly the same location on the metal strip 1 in order to prevent fluttering of the strip, but the fluttering vibration of the metal strip 1 is unavoidable. There has been a problem of contact with the cleaning device or uneven cleaning of the metal strip. This problem also occurred when washing only one side of the strip with high pressure water. In this figure, 3a to 3j are high-pressure water spray nozzles, and Y indicates the amplitude of fluttering vibration.

There was a limit. In addition, in a line that requires high-speed threading, the number of high pressure water washing header rows that satisfy the required washing energy is 10
There were 30 columns, and the equipment tended to be large.

Thus, the problem of flapping vibration of the running metal strip is eliminated. Furthermore, since the problem of fluttering vibrations has disappeared, it is now possible to freely bring the distance between the high-pressure water spray nozzle and the metal strip close to an appropriate range due to this problem, and also in terms of energy. It is advantageous and can deal with the cleaning of high-speed strip material.

の小スペース化に結びつけることができる。FIG. 2 shows the relationship between the distance of the high-pressure water spray nozzle and the impact force received by the object to be sprayed.
Since this relationship and the distance between the high-pressure water spray nozzles can be freely set close to each other, it is possible to reduce the spray pressure, which has been required for the distance between the high-pressure water spray nozzles. Also, on the surface side where the spray of the metal strip bent along the backup roll hits,
Since the warpage is given, an action of expanding fine irregularities on the surface occurs, and the cleaning effect is enhanced. As a result, the spray flow rate and pressure required for cleaning can be reduced. This also leads to a reduction in the number of spray headers installed, which can lead to a smaller space for cleaning equipment.

The metal strip 1 advances between the backup roll 2a and the high-pressure water spray nozzle 3a, which are arranged opposite to each other, the lower surface of the metal strip 1 is washed with high-pressure water, and subsequently, the backup roll 2b which is arranged oppositely. And the high pressure water spray nozzle 3b, the upper surface of the metal strip 1 is washed with high pressure water.

なった。FIG. 3 shows a metal strip high-pressure water cleaning apparatus according to another embodiment of the present invention. By bringing the backup roll 2a and the backup roll 2b closer to each other in this manner, it is possible to contribute to a reduction in the space of the cleaning device. By the way, when the cold-rolled steel sheet was degreased and washed with the high-pressure water washing apparatus shown in FIG. 1, the fluttering vibration of the metal strip, which was a conventional problem, was completely eliminated, and there was no particular problem even if the spray distance was reduced. . With respect to the cleaning effect, by increasing the spray distance and increasing the impact force, a sufficient cleaning effect as compared with the conventional one was obtained even with the same pressure as the conventional one. Therefore, it has become possible to deal with high-speed strip material.

能となる効果もある。According to the present invention, in high-pressure water washing of oil-coated metal strips after rolling, the rolls are installed as backups at the high-pressure water spray locations of the metal strips, so that flapping vibrations of the metal strips can be eliminated. Further, since the spray distance can be freely approached to the metal strip, there is an effect that it is possible to reduce the pump power by reducing the pressure of the spray, reduce the space, and deal with high-speed strip material.
