Problems solved by technology

[0002] At present, the connection between the cathode steel rod and the cathode soft busbar for the aluminum electrolytic cell in the prior art is generally to connect the cathode steel rod just after the furnace is directly connected to the crimping block connected with the soft busbar through the pressure plate. The crimping surface of the cathode steel rod that has just been built is relatively rough, and there is a high voltage drop between the crimping block and the crimping surface of the cathode steel rod. High and red, which not only affects the cathode current distribution of the electrolytic cell and the stability of production, but also directly increases the power consumption per ton of aluminum and the production cost of aluminum production; The connection of the crimping block still has the problem of easy rust

Embodiment Construction

[0008] Embodiment of the present invention: earlier make 2~4 bolt connection holes on the crimping surface of the cathode steel bar (1) that has just built furnace, the flat disk of the hand-held grinder (4) that sells on the market The grinding wheel on (5) is removed, and then the sandpaper (3) for grinding is fixed on the circumference of the flat plate (5) of the hand-held grinder (4) by bonding, and the hand-held grinding wheel is held by hand The handle of the grinder (4), so that the sandpaper (3) mounted on the flat plate (5) of the hand-held grinder (4) can grind the crimping surface of the cathode steel rod (1) back and forth, and grind the crimping surface After the light is bright, place the crimping block (2) on the crimping surface after the cathode steel rod (1) is polished, and make the crimping block (2) tightly crimp on the cathode steel rod (1) through the bolt (6). ) on the crimping surface after polishing; in order to prevent the crimping surface from rust...

Abstract

The connection method of cathode steel rod and cathode soft bus I aluminum electrolytic bath includes polishing the pressure connecting plane one the cathode steel rod with emery paper fixed onto hand grinding machine disc, painting compound conducting grease to the pressure connecting surface of the pressure connecting block and the polished cathode steel rod, and connecting the pressure connecting block with the cathode steel rod tightly with screws. The present invention has the advantages of greatly reduced voltage drop in the connecting part, simple operation, reliable work, stable production of electrolytic bath and long service life of electrolytic bath.

Description

Technical field: [0001] The invention relates to a method for connecting a cathode steel bar and a cathode soft bus bar for an aluminum electrolytic cell, and belongs to the technical field of connecting a cathode soft bus bar and a cathode steel bar. Background technique: [0002] At present, the connection between the cathode steel rod and the cathode soft busbar for the aluminum electrolytic cell in the prior art is generally to connect the cathode steel rod just after the furnace is directly connected to the crimping block connected with the soft busbar through the pressure plate. The crimping surface of the cathode steel rod that has just been built is relatively rough, and there is a high voltage drop between the crimping block and the crimping surface of the cathode steel rod. High and red, which not only affects the cathode current distribution of the electrolytic cell and the stability of production, but also directly increases the power consumption per ton of alumi...
