The main purpose of pickling cold-rolled steel plates is to remove oxide scale and rust on the surface to improve the surface finish and corrosion resistance of the steel plates. The pickling process usually uses dilute sulfuric acid or hydrochloric acid to corrode oxides and impurities on the surface of the steel plate, thereby purifying the surface of the steel plate. If the cold-rolled steel plate is rusted, the following measures can be taken to deal with it:
1. Mechanical treatment: Use sandpaper, wire brush, and other tools to sand to completely remove rusty surface materials.
2. Chemical treatment: You can use acidic solutions, such as dilute hydrochloric acid or pickling agents, to dissolve or remove rust on the surface of the steel plate.
3. Anti-rust treatment: The treated steel plate should be treated with anti-rust treatment in time. It can be covered with anti-rust paint, anti-rust oil, and other protective coatings to prevent it from rusting again.
4. Pay attention to environmental conditions: During storage and use, try to avoid contact with steel plates with water, humid environments, or chemical substances to reduce the possibility of rusting.
Please note that for large-area, severely corroded cold-rolled steel plates, it is recommended to consult professionals for treatment or replacement.
