Problems solved by technology

[0002] In today's aluminum electrolysis industry, metal aluminum is obtained by electrolysis of alumina. When aluminum is electrolyzed, alumina is in the electrolytic cell, and the temperature in the electrolytic cell is very high, reaching thousands of degrees. Since the electrolytic cell is composed of a cathode and a refractory brick After a period of time, it will cause leakage in some places of the electrolytic cell
If there is a leakage tank, it will cause the electrolytic cell to not work normally and must be repaired. On the one hand, the electrolytic cell cannot perform electrolytic aluminum work, and the output will drop. On the other hand, due to the maintenance of the electrolytic cell, the economic loss will be relatively large; It may also lead to casualties of workers operating on site
Therefore, it is very important to be able to predict the leakage of the electrolytic cell online in real time in the electrolysis workshop. Since the temperature in the cell is as high as thousands of degrees during the electrolysis of aluminum, it is impossible to observe the leakage in real time from the inside of the electrolytic cell. Currently, there is no such An accurate and effective detection method for leakage of aluminum electrolytic cell
