Description

Automation equipment for quickly centrifuging galvanized part and working method thereof

Technical Field

The invention relates to an automatic device, in particular to an automatic device capable of quickly centrifuging galvanized workpieces to remove zinc liquid with more residual surfaces.

Background

Hot dip galvanizing is a process in which molten metal reacts with an iron substrate to produce an alloy layer, thereby bonding both the substrate and the coating. The hot galvanizing is carried out by pickling steel parts, cleaning the steel parts in an ammonium chloride or zinc chloride aqueous solution or an ammonium chloride and zinc chloride mixed aqueous solution tank after pickling in order to remove iron oxide on the surfaces of the steel parts, and then sending the steel parts into a hot dipping tank. The hot galvanizing has the advantages of uniform plating, strong adhesive force, long service life and the like.

However, after galvanized parts are galvanized, more molten zinc remains on the surfaces, and the thickness of the galvanized film of the parts is not uniform due to the residual molten zinc on the surfaces, which affects the quality and the aesthetic degree of the products. In order to deal with the problem, a common method is to put the galvanized workpiece into a centrifuge for centrifugation and throw out the excessive liquid in time to obtain the galvanized workpiece with uniform film and stable thickness.
