Description

Technical Field

[0001] The utility model relates to the technical field of mining machinery, in particular to a casting surface passivation device for mining machinery. Background Art

[0002] Mining machinery is machinery directly used for mineral mining and enrichment, including mining machinery and mineral processing machinery. The working principle and structure of prospecting machinery are mostly the same or similar to those of mining machinery used for mining similar minerals. In a broad sense, prospecting machinery also belongs to mining machinery. In addition, a large number of cranes, conveyors, ventilators and drainage machinery are also used in mining operations. The passivation effect mainly refers to the phenomenon that under special conditions, the anodic process of metals or alloys is hindered and loses chemical activity, thereby producing a corrosion-resistant state. This process can form a dense oxide film on the metal surface, which can prevent corrosive substances from entering the interior of the metal, thereby improving the corrosion resistance of the metal.

[0003] When passivating the surface of a casting, the casting is mostly placed in a passivator for passivation. However, when using the existing passivation device, it is not convenient to fully passivate the casting, resulting in the surface of the casting being unable to fully contact and react with the passivator, making it easy for the surface of the casting to have unpassivated areas. Therefore, we propose a casting surface passivation device for mining machinery. Utility Model Content
