Anticracking reinforced conductive method for assembling anode and structure thereof

Abstract

The invention discloses a method for preventing crack and reinforcing conductivity of an assembled anode and a structure thereof. The invention adopts an aluminum steel anti-cracking conducting strip which can be connected with an aluminum guide bar and a steel claw beam by welding respectively to be connected with the outside of the existing aluminum guide bar and steel claw beam which are connected into a whole, wherein the aluminum steel anti-cracking conducting strip is made by welding an aluminum plate and a steel plate together by an aluminum steel explosive welding plate. The inventioncan effectively prevent a prebaked anode cell assembly from breaking and early cracking, and can improve the electric conductivity of the anode cell assembly and realize the effect of energy conservation and consumption reduction.

Description

technical field [0001] The invention relates to an anti-cracking and strengthening conductive method and structure of an assembled anode, which belongs to the technical field of welding strengthening of aluminum guide rods and aluminum steel beams of prebaked anodes in electrolytic aluminum production. Background technique [0002] As we all know, the prebaked anode is the heart of the prebaked aluminum electrolytic cell. During the firing start-up and operation of the pre-baked anode block, the assembly quality of the pre-baked anode block is to ensure whether its working condition is normal and stable in the process of aluminum electrolysis, to avoid such as bias current phenomenon, sick cell and accidental cell, and to obtain a good electrolytic cell. The key to technical and economic indicators.

AI Technical Summary

Problems solved by technology

[0003] The traditional prebaked anode adopts the peripheral groove welding method between the aluminum-steel explosion welding piece, the aluminum guide rod and the aluminum-steel beam. The welding part is a weak point, that is, the welding contact surface is not enough, and the welding strength is not enough to resist accidents. When the external strong shearing force and excessive pulling force, especially when the steel claw is red due to excessive current, the connection part is very easy to become a weak point of rupture

Once the connection parts are damaged and broken, it is easy to cause the anode to fall off, which will inevitably lead to accidents and affect normal production.
