Technical Field
[0001] The utility model relates to the technical field of coating spraying, in particular to a corrosion-resistant spraying device for the surface of a ductile iron casting. Background Art
[0002] Ductile iron castings are a special type of cast iron parts, also known as ductile iron or ductile iron. They are made by adding alloying elements such as magnesium and rare earth to ordinary cast iron and performing spheroidizing treatment during the solidification process of the casting. Spraying anti-corrosion agents on ductile iron castings is a measure to protect them from external corrosion. Spraying anti-corrosion agents can form a protective film to block the erosion of external oxygen, moisture and chemicals, and extend the service life of ductile iron castings. However, when spraying anti-corrosion agents, direct spraying is used to spray ductile iron castings. For some curved surfaces of ductile iron castings, it is easy to miss spraying and over-spraying, resulting in uneven coating. In addition, as the paint flows along the curved surface to form droplets, it is easy to produce paint bulges, affecting the spraying effect.
[0003] In view of the above problems, a ductile iron casting surface anti-corrosion spraying device is proposed to solve the above problems. Utility Model Content
