CATHODE OF ELECTROLYTIC CELL FOR PRODUCTION OF ALUMINIUM AND METHOD OF ITS REPAIR Russian patent published in 2013 - IPC C25C3/08 

FIELD: metallurgy.

SUBSTANCE: proposed cathode comprises jacket and lining with base made of heat-insulation and refractory materials, side lining, bottom of hearth sections with cathode rods and cathode downleads. The latter are made from the stack of flexible aluminium tapes, contact plate and steel adapter to be welded as-assembled to cathode rod and plugged to cathode bus. Cathode downleads are assembled in installing the lining by welding them to cathode rods and bolting downlead contact plates to the bracket. After disassembly of side lining, cathode rods with their downleads are extracted from cathode jacket, cleaned and transferred to cutting bay. Cutting is performed along the line or in zone of joint between rod and downlead metal adapter. After skinning the metal adapter end, cathode downlead is transferred for reassembly.

EFFECT: higher reliability due to larger number of aluminium tapes.
