Abstract

Existing methods and apparatuses for forming the non-oxidation atmosphere for a strip deposited in a molten metal for coating the strip and subsequently exposed in the air have several problems including the need to open and close the typical box type structure causing difficulty in maintaining a stable nitrogen atmosphere and the design of the structure resulting in high nitrogen use and associated cost. Described is an apparatus installed between a surface of a coating bath for hot-dip coating and an air knife facility for controlling a thickness of a coating metal attached to a surface of a strip to form a nitrogen cloud (curtain) around the strip coming from the coating bath is provided. Specifically, the apparatus of the present invention is spaced apart from the surface 10 of the coating bath by a predetermined distance, the apparatus includes: a body 3 having a semi-cylindrical shape, in which a lower surface thereof is opened toward the surface 10 of the coating bath, a slit 32 formed on an upper surface of the body 3 for allowing the strip 100 to pass therethrough, lower gas discharge parts 33 formed at a circumference of a lower end portion of the body 3 for jetting a nitrogen gas toward the surface 10 of the coating bath to block an ambient air, and inner gas discharge parts 31 disposed on both sides of the strip 100 in a facing manner across a lower surface of the body 3 in a width direction of the strip 100 for jetting a nitrogen gas toward the strip 100, wherein a plurality of injection nozzles 34 for jetting a nitrogen gas toward the strip 100 are formed within the body 3.
