FIXATION METHOD OF COOLING FINS ON CATHODIC CASING OF ALUMINIUM ELECTROLYSER Russian patent published in 2009 - IPC C25C3/08 C25C3/10 

FIELD: metallurgy.

SUBSTANCE: fixation method of cooling fin on cathode casing of aluminium electrolyser, containing lining from within metallic bath with longitudinal and butt walls and bottom, installed inside rigid frame, formed by force-summing elements, includes fixation on butt walls of metallic bath of cooling fins. On longitudinal and butt walls of metallic bath there are fixed cooling fins, implemented from material with high heat conductivity factor. Fixation is implemented at heating of basis of cooling fins up to temperature and plastic deformation and connection to walls of metallic bath through pressure-exerting element with ability of detachment of cooling fins from walls of metallic bath.

EFFECT: there are provided intensification of process of aluminium electrolysis in aluminic electrolysis by means of considerable increasing of heat withdrawal by vertical walls of cathode casing, conditions for implementation of stable technological process, increasing of durability of cathode device of aluminic electrolysis, achievement of thermal contact to walls of cathode casing, comparable to welded connection with ability of recoverable fins.
