METHOD OF CATHODE DEVICE PREPARATION PRIOR TO ALUMINIUM ELECTROLYTIC CELL SINTERING Russian patent published in 2008 - IPC C25C3/06 C25C3/08 

FIELD: technological processes.

SUBSTANCE: method of cathode device preparation prior to aluminium electrolytic cell sintering includes installation of metal casing, shaping of fire resistant base, with further mounting of bottom sections and lateral lining, seams filling with carbon mass, at that prior to mounting of bottom sections and lateral lining, fire resistant base is heated in its whole volume up to temperature of at least 100°C until free moisture is completely removed from the whole volume of fire resistant base, at that heating of fire resistant base is either performed from the bottom via bottom of metal casing or from the top, or simultaneously from the bottom via metal casing and from the top.

EFFECT: increase of electrolytic cell service life.
