Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing, in particular to a cooling device for hot-dip galvanizing. 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 has the advantages of uniform coating, strong adhesion and long service life.

[0003] After hot-dip galvanizing, workpieces need to be cooled. Existing hot-dip galvanizing cooling devices typically use a water pump to pump cooling water through a nozzle to cool the hot-dip galvanized steel. However, since the nozzle angles of hot-dip galvanizing cooling devices are usually fixed, it is difficult to adjust the spray cooling direction. This method can cause uneven cooling of the hot-dip galvanized workpiece, thereby reducing the cooling efficiency of the hot-dip galvanizing steel. Therefore, improvements are needed to address the existing problems. Utility Model Content

[0004] In view of the above situation, in order to overcome the current technical defects, the utility model provides a cooling device for hot-dip galvanizing with good cooling effect.
