摘要： The device of the present invention can enhance the quality of surface appearance through a nitrogen curtain section facilitating oxidation suppressing at a lower end portion of an air knife to suppress an oxide from being generated from an upper portion of a coating bath and block adsorption of the oxide to the surface of a coated layer.This device includes lower gas discharge bars spaced apart from the surface of the coating bath by a predetermined distance and discharging a nitrogen gas in a direction of the surface of the coating bath along a circumference of the coated steel sheet; a side cover extending upwardly slopingly in a direction of the coated steel sheet from the sides of the lower gas discharge bars; and upper gas discharge bars formed at an upper end of the side cover and discharging a nitrogen gas downwardly.
