Background
In the production process of electrolytic aluminum, the conductive anode group is used as an important power supply mechanism of the electrolytic cell, and the resistivity and the voltage drop of the conductive anode group have direct influence on the comprehensive energy consumption and the production cost of the electrolytic aluminum production. The conductive anode group is composed of an aluminum guide rod, an anode steel claw and an anode carbon block. The anode steel claw comprises a steel claw head, a steel claw beam and a steel claw foot, and the combination form of the anode steel claw can be assembled by adopting an integral casting or section welding mode. In the composition of the conductive anode, the anode steel claw is mainly made of solid cast steel or Q235 profile, the resistivity is high, and the voltage drop is increased and the energy consumption is increased in the electrolytic aluminum production process, so that the production cost per ton of aluminum is influenced. How to improve the comprehensive conductivity of the anode group of the electrolytic cell has important significance for realizing energy conservation and consumption reduction in the electrolytic aluminum industry.

Intuitively, the conductive anode prepared by the method adopts the aluminum core to replace the original steel solid structure, so that the resistivity of the conductive anode group can be reduced to a certain extent, but more problems exist in the specific implementation process: firstly, in the process of pouring aluminum liquid in the steel claw, due to the principle of thermal expansion and cold contraction, after the aluminum liquid is solidified and cooled, a gap is formed between the aluminum liquid and the steel claw shell, and the poor conductivity of the gap aggravates the electric quantity loss; secondly, in the running process of the electrolytic cell, the temperature of the electrolytic cell is as high as 960 ℃, and the metal aluminum with the melting point of 660 ℃ can be melted at high temperature, so that the power of the electrolytic cell is unstable, and the energy consumption is increased dramatically; thirdly, the molten aluminum metal will further erode the steel stud shell, risking perforation leakage and the like.
