Problems solved by technology

[0002] In the production process of electrolytic aluminum, before the anode carbon block is immersed in the electrolyte, the upper part is covered with a covering material, but the rest of the surrounding area is exposed to high temperature environment, causing oxidation. When oxidation occurs, slag, cracks, and block loss will occur. Seriously affect the economic benefits of aluminum electrolysis plants
[0003] The problem of anodic oxidation in China has also begun to attract the attention of electrolytic aluminum enterprises in recent years. Individual enterprises and design units have begun to test anodic anti-oxidation technologies and methods. Method, a company uses borax, industrial phosphoric acid, kaolin, water, etc. to make a coating and coat it on the surface of the oxidized carbon block. etc., can make the anode carbon block play the purpose of anti-oxidation, but the process is complicated and the effect is not obvious. At the same time, because these methods are all manually operated, the efficiency is low, and it cannot be widely used.
