Embodiment Construction

[0008] The anode carbon block group shown in accompanying drawing 1 and 2 is to form solid conductor (5) after pouring conductive slurry in the gap between the carbon bowl of phosphorus iron ring (4) and carbon block (6) and the cavity Partial cross-sectional view of the longitudinal side, the other longitudinal side is the same, but the length is different, omitted. Generally, the upper part of the anode carbon block group is an aluminum guide rod (1), and the lower part is connected with an aluminum-iron explosive block (2), an anode steel claw (3) and a carbon block (6), and the upper part of the carbon block (6) has a carbon Bowl, the legs of the anode steel claws (3) stretch into the carbon bowl, and there is a phosphorus iron ring (4) between the anode steel claws (3) and the carbon bowl. The conductive paste can be of many kinds, and it is prepared by adding the fine powder of the conductor into the solvent. The solvent should have good fluidity and volatility. For exam...

Abstract

A process for reducing electric resistance of anode carbon block group relates to improvement of inner structure of the anode carbon block group for aluminum electrolysis. Principally, an electric-conductive paste is poured into the hollow spaces and constringency gaps between the phosphorus hoop and the carbon bowls of carbon blocks, wherein the pulpous state electric conductor forms a solid conductor after drying, and then the phosphorus hoop and the carbon bowl walls of carbon blocks are cemented together more appropriately and more firmly. Said anode carbon block group can commendably eliminate the gaps and hollow spaces between the phosphorus hoop and the carbon bowls of carbon blocks, and then reduces the electric resistance and improves the electroconductivity at these positions, therefore it can drop down the voltage without changing the electrolytic tank pole clearance. If the voltage is not dropped down, the pole clearance is improved. Said invention can efficaciously reducethe electric power consumption per ton of aluminum and improve the electric effect.

Description

1. Technical field: [0001] The invention relates to the improvement of the internal structure of the anode carbon block group used for aluminum decomposition. 2. Background technology: [0002] The anode carbon block group is an important component of the aluminum electrolytic cell and mainly plays a conductive role. The anode carbon block group is generally composed of five parts: anode carbon block, steel claw, aluminum-iron explosive block, aluminum guide rod, and phosphorus pig iron casting ring. The phosphorus pig iron ring is formed by casting the molten phosphorus pig iron liquid in the gap between the carbon bowl and the steel claw of the carbon anode and cooling it. Its purpose is to connect the steel claw leg with the carbon block and play a conductive role. body function. The melting point of phosphorus pig iron is about 1400 degrees. The liquid phosphorus pig iron in the molten state must be cooled to room temperature rapidly after casting, and the volume shrin...
