Description

Technical Field

[0001] The utility model belongs to the technical field of flux plating tanks, in particular to a hot-dip galvanizing flux plating tank. Background Art

[0002] Hot-dip galvanizing is a process in which molten metal reacts with an iron matrix to produce an alloy layer, thereby combining the matrix and the coating. Hot-dip galvanizing involves pickling the steel parts first to remove iron oxide from the surface. After pickling, the parts are cleaned in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride before being placed in a hot-dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. In the hot-dip galvanizing process, a high-temperature aqueous solution composed of chemical raw materials such as ammonium chloride and zinc chloride is mainly used to hold the workpiece before hot-dip galvanizing. The purpose of the hot-dip galvanizing is to clean the surface of the workpiece so that the workpiece has maximum activity before the zinc is melted.

[0003] After searching, the publication number is: CN220352208U, which discloses a hot-dip galvanizing flux tank structure, which realizes the effect of sliding stirring of the solution in the flux tank. At the same time, it is convenient to remove the filter from the flux tank and to clean impurities on the filter. However, there are still some shortcomings: there is a gap between the filter and the stirring device. When cleaning the surface of the workpiece, impurities can easily fall from the gap to the bottom of the flux tank, losing the filtering effect. Therefore, improvement is needed.
