Problems solved by technology

In the electrolytic cell, the environmental conditions are extremely complex and harsh. In the environment where the temperature reaches 400-900 ° C, there is a strong magnetic field, and a large current of hundreds of thousands of amperes is continuously conducted, ordinary bonding materials will be damaged in a very short time. Phenomena such as hot melting, volatilization, and polycondensation lead to rapid denaturation of ordinary materials, loss of adhesive grip, residues of various impurities that will pollute the aluminum liquid, and a great increase in resistance. There is also the risk of the continuous anode carbon block falling off. Unable to meet the needs of continuous production of anode carbon blocks

Embodiment 6

[0061] An application of a sintered solidified material in the field of electrolytic aluminum. The sintered solidified material is applied to the continuation of the aluminum electrolytic prebaked anode carbon block through softening and sintering. The sintered solidified material is made into a thin sheet through pretreatment, and it is to be placed in the electrolytic cell. When the online anode is consumed to the point that a new anode needs to be added, the thin plate-shaped sintered and solidified material is sandwiched between two carbon blocks when the anode is connected. The sintered and solidified material in the shape of a thin sheet is softened first, and then sintered and solidified until the two anode carbon blocks are bonded into one.

Description

technical field [0001] The invention relates to the field of aluminum electrolysis, in particular to a sintered and solidified material for solidifying and connecting prebaked anode carbon blocks. Background technique [0002] The aluminum smelting electrolysis process is to use the anode carbon block suspended on the upper part of the tank and the cathode fixed at the bottom of the tank to conduct high-current direct current in the electrolytic tank. The main component in the tank is alumina (Al 2 o 3 ) electrolyte for electrolysis, the oxygen atoms react with the anode carbon block to generate CO 2 , CO gas is discharged, pure aluminum melt is generated at the bottom of the tank, and the smelting of metal aluminum is completed. Therefore, the anode carbon block participates in the reaction and is continuously consumed during the production process, and new anodes need to be replaced regularly. At present, the anodes used in the aluminum electrolysis process are all preb...
