Problems solved by technology

[0004] In order to overcome the shortcomings of the current general-purpose cathode carbon block steel rod group, the iron-carbon contact voltage drop between the cathode steel rod and the cathode carbon block is too high, and the resistivity is too large, the present invention proposes a new method that can reduce the number of cathode carbon blocks The design and construction scheme of the contact voltage drop between the iron-carbon bond and the cathode steel rod

Embodiment Construction

[0012] The technical scheme of a new type of cathode carbon block steel rod group is shown in the attached drawing figure 1 , figure 2 Shown, the biggest difference with existing common cathode carbon block steel rod group is that only a cathode steel rod (2) was set in the past in the same cathode carbon block (1) steel rod groove (5), and steel rod (2) two There are steel rods tamping paste (3) on both sides, which are connected with the cathode carbon block (1). And what new technology scheme adopted is two cathode steel rods (2), there is steel rod tamping paste (3) in the middle of two steel rods (2), and what the outer surface of two cathode steel rods (2) adopts high temperature resistant The conductive glue (4) is connected with the cathode carbon block (1).

[0013] The conductive glue (4) between iron and carbon must have high temperature resistance. Usually, resin is used as a bonding agent, graphite powder or boron carbide powder is used as aggregate, and it is ...

Abstract

The invention relates to a cathode carbon block steel bar group applied to an aluminium electrolytic tank structure technology. The cathode carbon block steel bar group has a biggest difference from the universal steel bar group of the cathode block at present that: only one cathode steel bar is arranged in a steel bar groove of the cathode block; and the two sides of a steel bar are both provided with steel bar ramming pastes which are connected with the cathode block.Compared with the prior art, the novel steel bar group of the cathode block adopts a new technical scheme that: two cathode steel bars are arranged in the steel bar groove; the steel bar ramming pastes are arranged between two steel bars, and the outer side faces of the two cathode steel bars are connected with the cathode block through a high-resistant conductive adhesive. The novel steel bar group of the cathode block is used for constructing a cathode lining of an aluminium electrolysis cell and can greatly reduce contact voltage of iron and carbon so as to achieve the aim of reducing power consumption of structural resistance of the aluminium electrolysis cell.

Description

technical field [0001] A new type of cathode carbon block steel rod group is applied to the masonry of the cathode conductive inner lining of the prebaked aluminum electrolytic cell. technical background [0002] Cathode carbon block and cathode steel rod are the main conductive material components for the cathode conductive lining of the aluminum electrolytic cell. A cathode rigid rod is placed in the middle of the rectangular steel rod groove, and there is a gap of about 15 mm between the two sides of the cathode steel rod and the rectangular steel rod groove and the top, and the gap is made of special graphite carbon steel Rod paste is used as filling material, which is tamped firmly with manual pneumatic tools, and the cathode steel rod and cathode carbon block are assembled together as the conductive part of the cathode lining of the aluminum electrolytic cell. [0003] The current general-purpose cathode carbon block steel rod group in the cathode block steel rod groo...
