Tower section, tower cap

Surface treatment of tower joints and tower caps: The requirement for polishing is to smooth out the welding slope on the enamel surface, round the sharp edges and corners, and remove the oxide skin and inclusions to reveal the metallic color. Oil burning decarbonization is the process of burning off adhered oils, organic matter, etc. at high temperatures. Sometimes when the carbon content of steel plates exceeds the standard requirements, high-temperature surface decarburization is also used as a compensation treatment. After the enamel tower section is damaged, it needs to be re coated at the enamel factory and subjected to heat treatment to eliminate hydrogen infiltration into the substrate at the porcelain explosion site. Sandblasting is the process of roughening the surface of the base material to increase surface free energy and specific surface area, thereby improving the adhesion between the base metal and the base glaze.
