Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of air knife, concretely is a kind of air knife for removing water mark of steel wire through plating-aiding pool. BACKGROUND

[0002] Steel wire has an important processing technology in the process flow of hot galvanizing, called plating-aiding process. Currently, clean nitrogen is used for blowing and protecting wiping process in hot galvanizing industry. The process is to use nitrogen wiping method to fill nitrogen with certain pressure at the zinc liquid surface of steel wire. Steel wire and zinc liquid will not be oxidized under the atmosphere of nitrogen, and the surface of steel wire is smooth. At the same time, nitrogen has certain pressure, which can blow and remove excess zinc to make the plating layer on the surface of steel wire smooth. The process mainly uses air knife blowing. Air knife is designed with a slit-shaped nozzle, and the airflow emitted by the nozzle is like a knife. The function is to blow off the excess zinc attached to the surface of steel, so that it returns to the zinc pot, which is the origin of "air knife".

[0003] Currently, the direction of some designed air knives is perpendicular to steel wire, which can only blow the water mark on the upper surface of steel wire, and cannot effectively blow and remove the water mark adhered to the whole surface of steel wire. Because of the difference in arrangement and blowing direction, the nitrogen air knife wiping test blows the zinc liquid on the surface of steel wire back to the zinc pot in vertical direction. During work, zinc liquid will not adhere to the air knife to cause damage to the air knife or block the blowing port. However, water will flow into the air knife during the blowing process of steel wire through plating-aiding pool. Since the water brought out by plating-aiding pool has certain corrosiveness, it will damage the structure of steel air knife and cause failure. CONTENT OF THE UTILITY MODEL
