Problems solved by technology

[0005] In addition, when phosphorus pig iron casting technology is used, the carbon block itself is a good metal liquid sealing material. After this part is processed, the sealing function of the material itself is wasted. It is not economical to fill this part

Abstract

A cathode assembly method that does not require filling and fixing the middle part of the carbon block, which relates to the technical field of electrolytic aluminum smelting, the steel rod groove of the cathode carbon block is not connected, and the middle part is separated by the carbon block body, and it is not necessary to carry out this part during assembly. The filling is firm, and when the phosphorus pig iron is cast and assembled, it is not necessary to use refractory materials to make a plug to separate the liquid phosphorus pig iron on both sides. The beneficial effects of the present invention are: when the cathode carbon block is assembled with the cathode steel rod, the process of filling and fixing the middle part of the carbon block can be omitted (applicable to ordinary assembly and phosphorus pig iron casting assembly); when phosphorus pig iron is used for casting assembly, The installation, disassembly and filling and fastening process of the refractory plug in the middle part of the carbon block are omitted, and the advantage of reducing the assembly cost of the cathode carbon block is more obvious.

Description

technical field [0001] The invention relates to the technical field of electrolytic aluminum smelting, in particular to a cathode assembly method that does not require filling and fixing the middle part of a carbon block. Background technique [0002] Domestic and foreign cathode carbon block manufacturers, when processing cathode carbon blocks, in order to reduce processing costs and reduce processing procedures, the steel rod grooves used to place cathode steel rods are through-processed. Moreover, at present, domestic electrolytic aluminum enterprises all adopt the carbon block assembly process of symmetrically installing two cathode steel rods in a steel rod groove (one company used to use one through steel rod technology, but this technology has been eliminated at present, and no enterprise is using it). There is a distance between 2 steel bars ranging from 200 to 300mm (different groove designs of different companies have different dimensions). The middle part of the s...
