[0002] Hot-dip galvanizing, also known as hot-dip galvanizing and hot-dip galvanizing, is an effective method for metal corrosion protection, mainly used in metal structural facilities in various industries. The hot-dip galvanizing process is to immerse the rust-removed steel parts in a zinc solution melted at about 500°C, so that a zinc layer adheres to the surface of the steel components, thereby achieving the purpose of corrosion protection. At present, a copper tube water spray device is used to cool the hot-dip galvanized steel wire. This type of water spray device directly sprays water from one side to the surface of the hot-dip galvanized steel wire for cooling. Under the action of the water spray, the upper solidified galvanized layer on the surface of the steel wire moves along the direction of the water spray, resulting in a thick coating on the side of the water spray device of the plated steel wire, and a thin coating on the side facing the water spray device, which affects the quality of the galvanized steel wire.
