Electrolytic Aluminum cathode aluminum rod

In the process of electrolytic aluminum production, series mode is adopted between electrolytic cells.The cathode of the electrolytic cell uses carbon as the cathode.Aluminum busbar connection between electrolytic cells,The aluminum bus is connected with the cathode carbon block by cathode steel rod .In the electrolytic production process, the bottom layer of the electrolyzer near the cathode is 20-30cm aluminum liquid, and the top layer is 15-22cm electrolyte. The anode is immersed in the electrolyte liquid, and the average voltage of the electrolyzer is : 3.9-4.3v from the bottom 4-5cm0 to the palm of the electrolyzer .V average =V anode +V bus +V electrolyte +V bottom +V effect +V connection bus equalization.

Tons of aluminum dc power consumption =2980X average voltage + current efficiency.Therefore, the only way to reduce the tons of aluminum dc power consumption is to reduce the average voltage and improve current efficiency. At present, the competition in electrolytic aluminum market is becoming increasingly fierce, and reducing energy consumption has become the key factor for the development of aluminum electrolytic production.Due to the damaged cathode carbon block in the overhaul tank, the steel rod was melted, and there was no conductive connector, so it was forced to stop the tank for overhaul. In view of this situation, the electrolytic aluminum cathode aluminum rod was designed.

Electrolytic aluminium cathode rods under the environment of higher than the melting point of 660 ° C were not melting.First, the bottom pressure drop can be reduced, saving tons of aluminum power consumption;The other is to realize that the electrolytic cell will not be forced to stop because the cathode has no conductive rod, thus greatly extending the life of the electrolytic cell, reducing investment, saving cost and increasing efficiency .The third will not affect the quality of the primary aluminum liquid because the original steel rod is melted.
