Abstract

PROBLEM TO BE SOLVED: To impart corrosion resistance to the journal parts of a backup roll by providing the journal parts with corrosion resistant sleeves, forming first protective layers by thermal spraying on the outer peripheries of these sleeves and forming second protective layers consisting of a fluororesin on the surfaces of these first protective layers. SOLUTION: The sleeves 4 made of a stainless steel are mounted at the exposed parts from the coating parts 3, such as urethane, of the journal parts 2 of the backup roll 11 consisting of an ordinary steel to impart the corrosion resistance to the base material of the journal parts 2. The surfaces of these sleeves 4 are thermally sprayed with alumina (Al2 O3 ) as the first protective layers 5 and these layers are subjected to a sealing treatment, by which the corrosion resistance of the exposed parts is improved. Further, the surfaces of the first thermally sprayed layers 5 subjected to the sealing treatment are coated with the fluororesin of the second protective layers 6 to drastically lower the surface roughness and friction coefft. of the surfaces of the exposed parts. As a result, the contact of the plating liquid and the base material of the journal parts 2 is interrupted and the chemical reaction thereof is prevented. The plating liquid adhered on the second protective layers 6 is crystallized and the removal of the plating liquid crystal is facilitated.

2. Description of the Related Art As shown in FIG. 3, a horizontal type electroplating equipment includes a strip A which moves horizontally as shown in FIG.
While passing the plating solution supplied from 4 through the plating bath immersed, electricity is supplied from the electrode 13 to the conductor roll 12 to plate the strip A. The backup roll 11 in the electroplating equipment rotates according to the passing of the strip A with the strip A sandwiched from below to hold the conductor roll 12 and prevent the plating solution from flowing out. Since this backup roll 11 is used to provide electrical insulation and corrosion resistance, to shut off the plating tank and the tank, and to drain the liquid, the surface is coated with a material having corrosion resistance and elasticity. . As shown in FIG. 2, the conventional backup roll 11 has a structure in which a hollow cylinder of ordinary steel is used as a roll body 1 and the surfaces of the main body and the journal 2 of ordinary steel are covered with urethane 3 or the like.

However, in the above-mentioned conventional backup roll, the entire journal of ordinary steel is not covered with urethane or the like, and is exposed near the bearing portion. If it adheres to the exposed portion of the journal, there is a problem that this portion is corroded. In recent years, the demand for quality improvement from customers has increased,
In order to produce a highly efficient plated steel sheet, there is a tendency to increase the flow rate of a plating solution in a plating facility. For this reason,
The plating solution scattered to the journal part also increased, and the corrosion of the journal part tended to be promoted.

However, when complete sealing such as using an oil seal is performed to prevent the scattered plating solution, crystallization of the attached plating solution cannot be avoided due to the characteristics of the plating solution. This causes the seal portion to stick, leading to poor rotation of the backup roll. For this reason, only a simple one such as a conventional drainer can be used for the seal, and splashing of the plating solution to the journal part has to be tolerated to some extent. Also, the fact that the plating solution scattered to the journal part 2 is crystallized means that
This means that a chemical reaction occurs with the ordinary steel that is the backup roll body, and the plating solution that has once adhered and crystallized cannot be removed.

However, for the above-mentioned reason, to newly manufacture the backup roll 11 from a corrosion-resistant material in order to improve the corrosion resistance of the backup roll main body 11, not only the cost is newly generated but also the existing backup roll is completely It becomes unusable and has a very large asset loss. Therefore, the present invention solves the above-mentioned problems, and provides the journal portion 2 with corrosion resistance using an existing roll.
It is an object of the present invention to provide a backup roll for an electroplating facility that can easily remove a plating solution adhered and crystallized.
