Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a strip guide device for an electrolytic cell, which performs pickling of strips and electrolytic treatment such as electroplating.

[0002]

[Prior art]

 FIG. 3 shows a vertical sectional view of an electrolytic pickling tank as an example of a conventional apparatus. In the figure, a tank 51 is filled with an electrolytic solution L, and a sink roll 52 is arranged on the inlet side and the outlet side thereof. An upper electrode 53 and a lower electrode 54 are provided above and below the pass line of the strip S, which connects the lower surfaces of both sink rolls 52.

An upper guide roll 61 and a lower guide roll 62 are rotatably arranged between the upper and lower electrodes 53 and 54 above and below the pass line.

The strip S is wound around both sink rolls 52 to run on a pass line in the electrolytic solution L, and the strip S is energized from the upper electrode 53 and the lower electrode 54 through the electrolytic solution L to perform electrolytic pickling. , Remove scales, oils, etc. on the surface.

When the strip S swings up and down during traveling, it comes into contact with the upper guide roll 61 and the lower guide roll 62. Due to this contact, the upper guide roll 61 and the lower guide roll 62 rotate to guide the strip S and prevent the strip S from contacting the upper and lower electrodes 53 and 54.

[0006]

[Problems to be solved by the device]

 In the conventional apparatus as described above, when the strip S swings up and down and comes into contact with the upper guide roll 61 and the lower guide roll 62, the upper and lower guide rolls 61 and 62 are immersed in the electrolytic solution L. In such a case, the roll inertia may not sufficiently rotate due to the roll inertia, and there is a problem that the surface of the strip S is scratched by slipping with the strip S.

It is an object of the present invention to provide a new strip guide device for an electrolytic cell which solves the above problems.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the strip guide device for an electrolytic cell of the present invention is an electrolytic cell in which the electrolytic cell is filled with an electrolytic solution and electrodes are arranged on both sides of a strip path line in the electrolytic solution. A liquid ejecting device is provided on both sides or one side of the strip pass line.

[0009]

[Action]

 The above-described strip guide device for an electrolytic cell of the present invention is configured such that the strip path line in the electrolytic cell is immersed in an electrolytic solution to run and the electrolytic solution or the plating solution is applied to both sides or one side of the strip that is electrolytically treated. Spray a liquid such as to guide the strip in a non-contact manner.

When the liquid ejecting apparatus is arranged on both sides of the strip pass line, when the traveling strip approaches either of the liquid ejecting apparatuses in an attempt to swing vertically or laterally, the strip and the liquid ejecting apparatus are separated from each other. Since the pressure between them becomes high and a force acts to move the strip away from the liquid ejecting apparatus, the strip is returned to the middle of both liquid ejecting apparatuses and stably travels on the strip pass line.

【Example】

 Hereinafter, an embodiment of the present invention will be specifically described with reference to the drawings. It should be noted that the same members as those of the conventional device are designated by the same reference numerals, and duplicate description will be omitted. FIG. 1 is a vertical sectional side view of an example of an electrolytic pickling tank, and FIG. 2 is an enlarged front view taken along the line II-II of FIG.

In these drawings, 1 is an upper floater, 2 is a lower floater, and a large number of slit-shaped injection ports 1 a, 2 a are respectively formed, and the strip S is immersed in an electrolytic solution L in an electrolytic cell 51. A plurality of upper electrodes 53 and a plurality of lower electrodes 54 arranged above and below the pass line of FIG. Each floater is connected by a supply pipe 3 to an electrolytic solution circulation supply device (not shown) installed outside the electrolytic cell 51. The electrolytic solution circulating and supplying device is connected to the electrolytic cell 51 by a discharge pipe (not shown).

Next, the operation of this device will be described. The strip S is wound around both sink rolls 52 disposed on the inlet side and the outlet side of the electrolytic bath 51 to run on the pass line in the electrolytic solution L, and current is supplied from the upper electrode 53 and the lower electrode 54 to perform electrolytic pickling. Then, the scale, fats and oils on the surface of the strip S are removed. Then, the electrolytic solution L refreshed by an electrolytic solution circulating and supplying device (not shown) is sprayed onto the strip S from the spray ports 1a and 2a of the upper floater 1 and the lower floater 2 to stabilize the running position. To guide you.

When the strip S approaches the upper or lower injection ports 1a, 2a in an attempt to swing up and down, the pressure between the strip S and the upper or lower floaters 1, 2 increases, and the strip S is removed. Since the force to move away from the floaters 1 and 2 acts, the strip S is returned to the middle of the upper floater 1 and the lower floater 2 and is stable without contacting the upper and lower electrodes 53, 54 and the upper and lower floaters 1, 2. And drive.

Further, according to the above-described embodiment, the refreshed electrolytic solution on the upper surface and the lower surface of the strip S is constantly supplied, so that the electrolytic effect can be promoted and the pickling time can be shortened.

The present invention is not limited to the above-mentioned embodiment, and can be applied to a strip path line having a vertical type.

[0017]

[Effect of device]

 As described above in detail, according to the present invention, the liquid jetting device is arranged on both sides or one side across the strip path line in the electrolytic cell to jet the liquid on the surface of the traveling strip. As a result, the strip can be guided in a non-contact manner so as to stably run on the pass line, so that the runout of the strip and the occurrence of scratches can be prevented.
