Technical Field

The application relates to the field of galvanizing equipment, in particular to a cooling system for hot galvanizing.

Background

After the workpiece is galvanized, the workpiece is placed into a cooling pool for cooling, and the cooled workpiece is placed into a passivation pool for further processing. Passivation is a film forming process in the galvanizing process, because zinc is an active metal, if passivation treatment is not carried out after the workpiece is galvanized, a coating layer becomes dark quickly, and white color appears in succession. In order to reduce the chemical activity of zinc, a solution is often used to form a layer on the surface of the zinc layer.

An operator puts a plurality of workpieces into the cooling tank through the lifting tool, after the workpieces are cooled, the operator controls the lifting tool to lift the workpieces from the cooling tank, the workpieces are suspended, water on the surfaces of the workpieces and in the workpieces is drained, and finally the workpieces are put into the passivation tank, so that the situation that water on the workpieces enters the passivation tank to dilute solution in the passivation tank is reduced.
