Abstract

PURPOSE:To obtain a plated steel sheet practically without a difference in glossiness between the front and rear by providing a couple of the upper rubber roll and lower metallic roll to interpose a traveling steel strip and crushing the protrusion of plating on the lower surface of the strip. CONSTITUTION:A couple of the upper rubber roll 11 and lower metallic roll 10 are provided on the outlet side of the final conductor roll 5a and backup roll 6a to interpose a traveling steel strip 3. The strip 3 is interposed between the rubber roll 11 and metallic roll 10, and the protrusion of plating on the lower surface of the strip 3 is crushed by the metallic roll 10 without regulating the pressure of the strip 3. The rubber roll 11 and metallic roll 10 can be set at an appropriate position on the downstream side of the conductor roll 5a and backup roll 6a, e.g. on the upstream side of a winder.

Compared to vertical electroplating equipment, horizontal electroplating equipment has
It has been widely used for galvanizing and the like since ancient times because it has the advantage of low voltage loss and does not require large strength for conductor rolls and support rolls. FIG. 2 is a schematic front view of a conventional horizontal electroplating apparatus generally used for galvanizing steel strips as materials to be plated. A plurality of electrolytic cells 2 are sequentially arranged in the horizontal electroplating apparatus 1, and each electrolytic cell 2 has a steel strip 3 to be transferred.
A pair of anodes 4.4° are arranged correspondingly above and below.

Since the pair of anode electrodes 4.4' in two series are arranged in sequence, the distance of transport of the steel strip 3 in the electrolytic cell 2 becomes long, which causes the steel strip 3 to fluctuate or become loose.In order to prevent this, A support roll 9 is generally provided. A conductor roll 5 and a backup roll 6 are installed near the inlet and outlet sides of the steel strip in each electrolytic cell, where the steel strip is negatively charged and the plating solution 7
Inside, an electrode reaction is carried out to galvanize the surface of the steel strip. In this case, a dam roll 8 is used to prevent the plating solution from flowing along with the steel strip and flowing out of the tank, and to maintain the level of the plating solution at a constant level. The electrolytic bath 2, the anode 44° conductor roll 5, and the backup roll 6 constitute a plating section.

On the other hand, on the opposite side (lower side) of the steel strip where there is no conduction crawl, the steel strip is pressed by soft material dam rolls and backup rolls, so
The convex portion of the plating on the back side of the steel strip on the opposite side of the steel strip was hardly crushed, and there was no change in the plating as described above. As a result, the appearance of the opposite side (lower side) of the steel strip is almost unchanged without becoming glossy, so the surface of the steel strip ("two sides")
The gloss of the back surface (lower surface) will be significantly different.
