FIELD: metallurgy. ^ SUBSTANCE: invention relates to nonferrous metallurgy, particularly relates to structure of cathode assembly of aluminium electrolytic cell and can be used at designing of new and reconstruction of operating electrolytic cells. Cathode assembly of aluminium electrolytic cell, containing - casing, coal baked in the hearth blocks, fixed in block by baked in the hearth mass current-carrying components and refractory plates, located under coal baked in the hearth blocks, current-carrying components are implemented in the form of packet of aluminium foil, located under each coal baked in the hearth block by all its surface, herewith coal baked in the hearth blocks are implemented as solid without bottom clearance. ^ EFFECT: there is provided increasing of durability of cathode assembly ensured by reduction of value of heat stress between block and current-carrying component, and also reduction of electricity consumption ensured by decreasing of contact electrical resistance and improvement of electrolytic aluminium ensured by excluding of pollution of it by iron. ^ 2 cl, 1 dwg, 1 tbl |
