Description

Technical Field

[0001] The invention relates to the technical field of hot-dip galvanizing, and in particular to a superheated steam generator device for a vacuum galvanizing blowpipe line. Background Art

[0002] Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to first pickle the steel parts to remove the iron oxide on the surface of the steel parts. After pickling, they are cleaned in an ammonium chloride or zinc chloride aqueous solution or a mixed ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life.

[0003] Before hot-dip galvanizing of existing metal products, it is necessary to spray a plating agent on the metal to help the metal galvanizing. However, the spraying effect of the existing plating agent is not uniform enough. At the same time, spraying the plating agent inside the steam generator will cause the residual plating agent to adhere to the inner wall of the steam generator, making it inconvenient for subsequent users to clean the inside of the steam generator. In addition, the plating agent cannot be recycled, which also increases the cost of use. Summary of the invention
