The specific process of anti-oxidation of the copper mould tube
Anti-oxidation of copper mould tube:
1. A passivation film is formed on the surface of the copper mould tube to prevent the surface from darkening, and improve its corrosion resistance, discoloration resistance, and oxidation resistance without affecting the welding performance. Especially when using copper mould tubes, passivation treatment after polishing, the original solution of the amount of anti-oxidant can be used directly.
2. The temperature is 20 to 50 degrees Celsius, and the time is 3 to 5 minutes. The anti-oxidation protective agent is an anti-oxidation process after the copper polishing process. During use, the workpiece should be immersed in the chemical and slightly shaken so that the workpiece can fully contact the chemical . The anti-oxidation protective agent has no pungent odor, easy to operate with high production efficiency. However, after the workpiece is treated with chemical water, the surface must be cleaned with clean water or pure water, otherwise it will affect the surface of the workpiece.

In continuous casting, low corrosion resistance often occurs, which directly leads to uneven composition and will eventually affect the smelting quality. In or
