Zusammenfassung: | The invention relates to an anti-corrosion process for a tower crane bracket. The anti-corrosion process comprises the following steps: S1, physically cleaning the surface of the bracket; s2, chemically cleaning the surface of the stent; s4, surface treatment is conducted, specifically, the surface of the support is subjected to sanding treatment through a sand mill, so that the surface roughness of the support reaches Ra100; s5, primary coating powder treatment: coating the coating powder on the surface of the bracket, and pressing through a pressing plate, so that the thickness of the coating powder reaches 1-2mm; s6, primary heat treatment is conducted, specifically, the support is heated at the temperature of 1200-1500 DEG C, so that the wrapping powder on the surface is subjected to hot melting; s7, secondary powder wrapping treatment, wherein aluminum oxide powder is sprayed to the surface of the support through a high-pressure spraying machine to form a secondary powder wrapping layer with the thicknes |
