Description

Technical Field

[0001] The utility model relates to the technical field of galvanized steel strip processing, in particular to a zinc flower generating device for galvanized steel strip. Background Art

[0002] Galvanized steel strip is a cold-rolled or hot-rolled, long and narrow steel strip plate coated with a layer of raw materials called (zinc, aluminum) to varying degrees. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. The hot-dip galvanized steel strip substrate undergoes complex physical and chemical reactions with the molten plating solution to form a corrosion-resistant, tightly structured zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel strip substrate. Therefore, it has strong corrosion resistance.

[0003] Zinc spangles usually refer to the appearance of grains formed after the hot-dip galvanized sheet is pulled out of the zinc pot and the zinc layer cools and solidifies. The size, brightness and surface morphology of zinc spangles depend on a series of factors, but are mainly related to the composition of the zinc layer and the cooling method. The principle of producing zinc spangles is to try to reduce the solidification temperature of the zinc liquid.

[0004] In the process of producing existing galvanized steel strip with zinc spangles, it is necessary to generate crystal nuclei as early as possible. The water mist method is a common way to promote the production of zinc spangles. The principle is to spray water mist (a mixture of water and steam or water and air) on the surface of the galvanized steel part when the pure zinc liquid has not solidified to form crystal nuclei. The unsolidified zinc liquid diffuses outward from this starting point to form zinc spangles. The existing zinc spangle generating device cannot maintain a relatively appropriate angle and spacing between the water mist and the galvanized steel strip, which will prevent the crystal nuclei from being generated earlier, and will cause the zinc liquid to solidify before fully forming zinc spangles, which will affect the production of zinc spangles.

[0005] Therefore, those skilled in the art provide a zinc spangle generating device for galvanized steel strip to solve the problems raised in the above background technology. Utility Model Content
