High-electric-conductive anode assembly effectively solving inward-bending deformation

Abstract

A high-electric-conductive anode assembly effectively solving inward-bending deformation belongs to the technical field of anode electric-conductive devices in electrolytic aluminium industry. The invention particularly relates to a high-effective anode assembly effectively solving the inward-bending deformation, which not only solves a problem of inward bending of a steel claw, but also reduces welding quantity, is excellent in replaceability and is significantly higher than a cast steel claw in electric conductivity. The anode assembly includes a supporting cross beam which is characterized by including a first U-shaped steel board. An aluminum boss is disposed internally in the middle of the first U-shaped steel board through a bolt assembly. The upper end of the aluminum boss is stretched out from the upper part of the supporting cross beam. Two movable cross beams are respectively disposed in both the two ends of the first U-shaped steel board. Each movable cross beam includes a second U-shaped steel board which is connected to each end of the first U-shaped steel board in a sleeving manner. The second U-shaped steel boards are connected to the first U-shaped steel board through the bolt assembly in a long bar hole in the first U-shaped steel board. Two steel claw heads are respectively disposed on two ends of the bottom of the first U-shaped steel board.

Description

technical field [0001] The invention belongs to the technical field of anode conductive devices used in the electrolytic aluminum industry, and in particular relates to a highly conductive anode device that effectively solves inward bending deformation. Background technique [0002] Aluminum electrolysis production is an energy-intensive process. According to the survey, electric energy accounts for 24% of the cost of primary aluminum production in the world, while the consumption of electric energy for primary aluminum production in my country accounts for 30% to 50%. For this reason, major aluminum-making enterprises in the aluminum industry have carried out detailed analysis on the electrolysis process and electrolysis process, and researched and explored the methods and ways of saving energy and reducing consumption in the aluminum-making process. [0003] After analyzing the aluminum electrolysis process and its key equipment, it is found that the electrolytic cell bod...

Problems solved by technology

[0006] At the same time, a batch of test structures of anode devices with steel shell and aluminum core composite structure have appeared on the market, which have greatly improved the electrical conductivity, but the production cost is high, the service life is poor, the structure is resistant to thermal deformation, and the aluminum core is melted and infiltrated. Leakage and other problems are more serious; after long-term use, the aluminum core will be separated from the steel shell due to melting, resulting in a significant reduction in conductivity and cannot be repaired
