ELECTROLYSIS UNIT BOTTOM FOR OBTAINING ALUMINIUM Russian patent published in 2012 - IPC C25C3/08 

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy, and namely to devices used during aluminium manufacture with electrolytic method. Electrolysis unit bottom for obtaining of aluminium includes bottom units with slots, current-carrying bars, inter-unit connection in the form of refractory elements from silicone carbide, which are connected by means of inter-unit pulley from bottom mass and having the length equal to length of bottom unit, and the height equal to 0.35-1 of height of inter-unit joint.

EFFECT: providing the possibility of increasing service life of cathode device of aluminium electrolysis unit owing to improving the stability of inter-unit joint to sodium penetration, improving the stability to bottom destruction with compensation of its burning-out, improving grade of manufactured metal and reducing specific power consumption.
