The present invention relates to a facility for surface treatment of a steel sheet, and more particularly, to a water removing apparatus of the surface of the plated steel sheet to remove the moisture adhering to the surface of the plated steel sheet during the strip plating operation in the electroplating process.

In general, plating of a steel sheet is an operation of coating a surface of the steel sheet with a material that maintains a stable state or a material that suppresses elements of the surface reaction of the steel sheet in order to prevent the steel sheet from being oxidized and corroded.

As a method for plating, a method of controlling environmental conditions using acid vapor removal in the air, a method of properly selecting a material that stabilizes a surface state or a material that suppresses an element of a surface reaction, and an environment of a surface by plating or painting And electrochemical control using a sacrificial electrode (or an inert electrode).

In particular, electro zinc plating, which is one of electrochemical control methods, is mainly used for manufacturing automotive surface-treated steel sheets, and plating is performed using zinc-nickel or zinc-iron.

The equipment in which the electro-galvanizing operation is performed is a vertical type to plate using an anode electrode located horizontally above and below the strip according to the structure of the plating cell, and the plating is performed using an anode electrode installed vertically on the vertical path of the strip. It is classified into a vertical type or curved shape which adheres to a large diameter conductor roll and performs plating by using a roll and an anode electrode located below the roll as the roll rotates.

In particular, the curved type was developed for one-side plating and called a carousel (CAROSEL: Consumable Anode One-Side Electrogalvanizing Line).

In the carousel type plating, an electrolytic solution containing a plating material is filled in a plating cell, and the plating material is applied to an anode electrode in an adjacent position while the steel sheet to be plated is wrapped in a current-carrying roll rotated by a motor. The steel sheet is plated by the action of transferring to the surface of the steel sheet.
