Description

TECHNICAL FIELD

[0001] The application relates to a galvanizing device for steel wire processing. BACKGROUND

[0002] Steel wire is a widely used basic material in industrial production, and its corrosion resistance directly affects the service life and safety of the product. In order to improve the corrosion resistance of steel wire, the industry generally uses hot-dip galvanizing process to treat the surface of steel wire, which covers a layer of zinc on the surface of steel wire to form a reliable corrosion barrier. The production process of steel wire hot-dip galvanizing mainly includes pretreatment, solvent treatment, hot-dip zinc and take-up, etc. In the pretreatment stage, the surface of the steel wire is pickled and rusted to remove impurities and oxide layers; then a solvent containing ammonium chloride is coated on the surface of the steel wire and dried, and then the steel wire is immersed in molten zinc to complete hot-dip zinc, and finally a zinc layer is formed on the surface of the steel wire.

[0003] After the hot-dip zinc process, the zinc layer on the surface of the steel wire is usually uneven in thickness and has excess zinc, which needs to be removed by wiping to ensure the uniformity of the zinc layer thickness and improve the galvanizing quality. At present, the industry commonly uses gas wiping to complete this process, for example, Chinese patent CN110172659B discloses a steel wire non-contact gas wiping galvanizing device, which is provided with a strip-shaped through hole on the gas collecting box in the transverse direction, a first fixed bolt is slidably arranged in the strip-shaped through hole, the first fixed bolt passes through the strip-shaped through hole and is locked on the fixed frame, one end of the connecting pipe is communicated with the gas collecting box, and the gas knife is communicated with the other end of the connecting pipe, so that the steel wire and the gas knife are more reasonably arranged, the outer surface of the steel wire is completely contacted with the gas, and the wiping effect and the production quality of the steel wire are ensured. However, when the steel wire is just completed hot-dip zinc, the surface zinc layer is in a molten state, but the gas used for wiping is usually at room temperature. After the gas contacts with the high-temperature zinc layer, the zinc layer will quickly cool and solidify, making it difficult to completely wipe off the excess zinc layer. At the same time, the original zinc layer thickness after galvanizing is different, and the cooled and solidified zinc layer will further exacerbate the uneven thickness problem, resulting in poor wiping effect, poor zinc layer thickness consistency and serious impact on the galvanizing quality of the steel wire. SUMMARY

[0004] The application provides a preheating type galvanizing device for steel wire processing, which solves the problem that the existing galvanizing device is prone to cause rapid cooling and solidification of the zinc layer due to low gas temperature when wiping the excess zinc layer on the surface of the steel wire after galvanizing, resulting in poor wiping effect and uneven zinc layer thickness.
