に開示されている。2. Description of the Related Art In a continuous electroplating apparatus, as is well known, an electrode is used as an anode, and a plated steel strip is used as a cathode, and plating is continuously performed while energizing in a plating solution. As described above, when the plated steel strip passes through the electrode position, an accompanying flow of the plating solution occurs due to the passage of the plated steel strip, a negative pressure is applied between the electrode and the plated steel strip, and the plated steel strip contacts the electrode. Scratches. In order to avoid such difficulties, a tapered surface is formed that slopes in the width direction of the inner surface of the electrode toward the plate passing direction, and a liquid film is formed between the plated steel strip and the insulator to insulate the plated steel strip. It is disclosed in Japanese Patent Publication No. 6-13759 to avoid contact with the electrode by preventing contact with the body.

ある。That is, the plating solution retaining projections 2
A liquid pressure is generated in most parts of the electrodes 1 and 1a in the width direction, the liquid pressure is continuously maintained by the continuous passing of the plated steel strip 3, and the plating solution retaining projections 5 provided on the edge masks 4 and 4a. As a result, the plating solution flowing out of the width direction of the passing position of the plated steel strip 3 is suppressed, and a stable plating solution pressure (retaining portion) is formed and held by the plating solution retaining projections 2.
Electrodes at both ends in the width direction of the plated steel strip 3 are prevented by the plating solution stagnation portion (plating solution pressure) formed immediately below the plating solution stagnation projections 5 while preventing contact with the electrodes 1, 1a at the center in the width direction. 1, 1a is reliably prevented. In the passing of the plated steel strip 3, a crown is formed on a passing roll to prevent rocking (meandering) in the width direction of the plated steel strip 3, and both ends in the width direction of the plated steel strip 3 in the passing. The department is
Since the tension is slightly lower than that at the center in the width direction, it easily swings and easily contacts the electrodes 1 and 1a. However, as described above, the plating solution staying projections 5 disposed on the edge masks 4 and 4a cause the plating steel strip to have a large thickness. Plating solution stagnation portions (plating solution pressure) are formed at both ends in the three width directions, and contact with the electrodes 1, 1a at both ends in the width direction of the plated steel strip 3 can be reliably prevented. The plating solution retaining projections 2 and the plating solution retaining projections 5 are arranged on the electrodes 1, 1a and the edge masks 4, 4a at positions opposite to both surfaces (front and back surfaces) of the plated steel strip 3. .

形成することができる。The projection height of the plating solution retaining projections 2 provided on the inner surfaces of the electrodes 1 and 1a as described above is 2 to 35 mm, and a plurality of strips are provided in the direction of three plated steel strips. Thus, a plating solution stagnation portion is generated at the center in the width direction of the plated steel strip 3 to maintain the liquid pressure and avoid generation of a negative pressure between the electrodes 1, 1a and the plated steel strip 3. The height of the plating solution retaining projections 5 provided on the edge masks 4 and 4a is 2 to 35 mm, and the plating steel strip 3 is projected from both ends in the width direction to the center at a length of 5 to 200 mm. By arranging a plurality of bodies in the direction in which the plated steel strip 3 passes,
The plating solution is prevented from flowing out of the width direction of the pass-through position to prevent the plating steel strip 3 from being in contact with the electrodes 1 and 1a at both ends in the width direction. Since it is possible to suppress the flow out of the band 3 passing plate position to the outside in the width direction, it is possible to reliably form the plating solution pressure in the center in the width direction of the plated steel band 3.

The liquid pressure tends to be negative between the electrode on the exit side and the strip-plated steel strip, and the liquid pressure becomes negative even between the electrode on the input side and the strip-plated steel strip if the sheet is passed at a higher speed. hand,
Since the contact of the plated steel strip with the electrodes occurs, the electrodes 1, 1a on the entry side and the edge masks 4, 4 are changed depending on the passing speed.
The plating solution staying projections 2 and the plating solution staying projections 5 are disposed only on a as described above. Also, when there is a possibility that contact between the electrode and the plated steel strip may occur on the entry side, as described above, the plating solution stagnation projection 2 and the electrode 1 and 1a and the edge masks 4 and 4a on the entry side may also be used. The plating solution retaining projections 5 are provided.
