Description

Technical Field

[0001] The utility model relates to the technology of metal castings. Specifically, it relates to a device for passivation treatment of the surface of metal castings. Background Art

[0002] Passivation refers to the process in which a metal is oxidized by a strong oxidant or an electrochemical method to make the surface become an inactive state, that is, the passivation process. It is a method to make the metal surface transform into a state that is not easily oxidized and delay the corrosion rate of the metal. In addition, the phenomenon that a chemically active metal or alloy has its chemical activity greatly reduced and becomes a noble metal state is also called passivation. Nitric acid cleaning is usually referred to as passivation.

[0003] During the use of the existing device for passivation treatment of the surface of metal castings, the metal castings are usually adsorbed by a magnetic adsorption method and then transported to the passivation tank. However, for materials that do not have magnetism, they are generally transported manually and then put into the passivation tank, which is time-consuming and laborious.
