Problems solved by technology
[0002] At present, the carbon anode steel claw protection ring used in the production process of electrolytic aluminum is usually made of carbon or carbon-containing materials. During the manufacturing process, a large amount of asphalt and tar fumes that seriously pollute the environment will be produced; In the process of use, it is easy to burn excessively, and consume electric energy in vain, and the electric energy is converted into heat energy and lost, and at the same time releases CO 2 gas, increasing CO during electrolysis 2 Gas emissions have a certain impact on the environment
In the production process of electrolytic aluminum, because there is not enough oxygen to completely burn off the carbon powder in the electrolytic cell, resulting in fire eye carbon slag, the carbon anode protection ring will also produce a certain amount of carbon powder falling into the electrolyte, which causes electrolytic aluminum In the production process, the amount of fire eye carbon slag increases and the current consumption increases. The carbon content of fire eye carbon is only about 30%, while the content of alumina and fluoride salt is 70%. The increase of fire eye carbon slag means that the raw materials for the electrolysis process are increased. Loss
The increase of carbon slag in the fire eye will also increase the probability of electric effect
