程において大量の不良品を出すことにつながる。However, Canlite, which is a steel sheet for tinplate processed in a continuous annealing facility line (C.A.P.L.), has a lower product orthogonality rate than other tinplate products. As a non-direct factor, spot stains account for a large proportion. The spot stains are water or oil splashes between the electrolytic cleaning of the continuous annealing line and the front of the furnace and adheres to the strip, and a thick oxide film or adsorption film is formed on the adhered parts during annealing. The oxide film or the adsorption film is divided and remains in the plating pretreatment without being removed, and the areas with good plating are distributed in rows along the scratches, and the dirty areas are in rows and islands. The mixture has a uniform mixture distribution and a difference in gloss occurs. This cannot be confirmed in the tin plate, and the appearance defect is not found until the tin plate rises after plating, and as a result, a large number of defective products are produced in the tin plate manufacturing process.

点汚れの発生を防ぐことができる。In the present invention, since the air wiper is arranged between the ringer roll and the dryer, the splashed water adhering to the strip is blown off by the air wiper, and the splashed water suction device is provided in the casing surrounding the ringer roll. As a result, it is possible to suck the splashed water that hits the casing and bounces back and prevents the splashed water from adhering to the strip. As a result, it is possible to prevent the generation of surface spot stains due to splashed water.

上する。According to the present invention, since the air wiper is arranged between the ringer roll and the drier, the splashed water adhering to the strip is blown off by the air wiper, which results from the splashed water adhering to the strip in the plating step. The occurrence of spot stains can be prevented, and by providing a splash water suction device in the casing surrounding the ringer roll,
Since the splashed water that hits the casing and rebounds is sucked in to reliably prevent it from adhering to the strip, it is possible to prevent the generation of spot stains on the surface due to the splashed water that has adhered to the strip in the plating process after annealing, and to prevent Yield is improved.
