CATHODE SECTION OF ALUMINUM CELL MOUNTING METHOD Russian patent published in 2008 - IPC C25C3/08 

FIELD: processes for mounting cathode devices of aluminum cell.

SUBSTANCE: method comprises steps of arranging electric current supply metallic rod in groove of carbon unit on layer of electrically conducting yielding material solidified at mounting process; then filling gap between lateral walls of groove and surface of metallic rod till height consisting of 0.6 - 0.9 of rod height with carbon containing electric-contact plastic mass and filling remaining portion of said gap with refractory gas -impermeable paste and providing solidification of said paste. Mounting process of cathode sections according to invention allows provide high quality and reproducibility of reliable electro-mechanical contact of system "hearth unit - electric current supply rod", integrity of cathode units and hearth during operation.

EFFECT: increased useful time period, improved technical and economic parameters of cell.
