[0002] The flux coating is mainly used to remove the surface oxide of copper wire and play a secondary protection role in the hot-dip galvanizing production process. It can also play an interfacial active role, which is indispensable in the hot-dip galvanizing production. When the existing hot-dip galvanizing process is in production, it is often constructed in a larger factory building, which occupies a large area and has a large space waste rate. In addition, during the hot-dip galvanizing process, it is always necessary to manually scrape off the zinc on the surface of the zinc pool due to the temperature drop, so that there will be no large pieces of uneven metal zinc attached to the steel surface after hot-dip galvanizing. This process is relatively dangerous, and workers also have to wear thicker protective gear, which is very inconvenient. Improvements are needed to address the above problems. Utility Model Content

A moving block 12 is threadedly connected to the reciprocating screw 11. The structural characteristics of the reciprocating screw 11 can enable the moving block 12 to move back and forth periodically; an L-shaped rod 13 is fixedly installed on the moving block 12, and a plurality of connecting rods 14 are evenly fixedly installed on the L-shaped rod 13. A scraper 15 is fixedly installed at the lower end of the connecting rod 14. The scraper 15 contacts the zinc liquid on the hot zinc pool 9 and can scrape off the solidified zinc liquid and zinc slag on the surface; an air knife 16 is symmetrically fixedly installed at the opening of the hot zinc pool 9. The gas of the air knife 16 is nitrogen. A large amount of high-pressure nitrogen sprayed by the air knife 16 isolates external oxygen, greatly reduces the probability of zinc reacting with oxygen in the air, reduces the generation of zinc slag and product defects caused by zinc slag adhering to the strip steel, and can also make the overall galvanizing more uniform.

[0023] As a technical optimization scheme of the utility model, the pretreatment component includes a pickling tank 17 and an immersion tank 18 located on the base 1. The pickling tank 17 can be placed in a solution of hydrochloric acid or sulfuric acid with a good ratio; the immersion tank 18 is placed in an immersion plating solvent; partitions 19 are symmetrically fixedly installed on the base 1, and hot air dryers 20 are symmetrically fixedly installed on the partitions 19, so as to quickly dry the material as a whole, facilitate the direct implementation of the next operation, and reduce time waste.

[0028] Working principle:

[0029] Now hang the material through the hook 8, control the bottom plate 5 to move on the linear hanging rail 3, and when it moves to the top of the pickling tank 17, control the electric hoist 6 to descend, and immerse the material in the pickling tank 17. After a period of time, control the material to enter the leaching tank 18 for immersion, and then control the bottom plate 5 to pass through the annular hanging rail 4 and enter the top of the hot zinc tank 9 to lower the material. After lowering, the motor 10 works to drive the scraper 15 to move back and forth, and scrape the zinc slag and solidified zinc on the surface to one side. After rotating and scraping for a period of time, stop working, turn on the air knife 16 and start blowing, and control the material to rise. When passing through the air knife 16, the excess zinc liquid on the material will be blown off, and at the same time, it can quickly dissipate heat and reduce the contact time with oxygen, thereby having better product quality.

The specific implementation method is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
