[0002] Hot-dip galvanizing is also called hot-dip galvanizing and hot-dip galvanizing. It is to immerse the rust-removed steel parts in a molten zinc solution at about 500°C to make a zinc layer adhere to the surface of the steel parts, thereby achieving the purpose of corrosion protection. Before the workpiece is hot-dip galvanized, it is necessary to use a pickling tank to remove the oil and rust on the surface of the workpiece. The existing technology has the following problems.

[0003] The existing pickling tank generally only pickles the workpiece up and down twice to replace the contact surface between the workpiece and the acid solution, thereby accelerating the pickling process to remove oxides and rust. Although it can achieve a certain effect, the effect is general and cannot significantly accelerate the pickling process. Utility Model Content
