METHOD FOR PROTECTING GRAPHITE LINING OF ALUMINIUM CELL Russian patent published in 2001 - IPC

Abstract RU 2164556 C2

FIELD: equipment for aluminium production. SUBSTANCE: method comprises steps of forming (before closing contacts of electric circuit of aluminium cell) onto anode projection bottom layer of electric resistance from charge containing boron anhydride or boron acid, titanium dioxide and coke; after forming such layer pouring onto anode projection bottom melt metal and closing contacts of electric circuit for applying electric current or pouring metal onto bottom after forming electric resistance layer and then applying electric current. EFFECT: improved strength of graphite lining, enhanced efficiency of aluminium cell, increased useful life period of cell, enhanced quality of produced aluminium, lowered electric energy and labor consumption. 3 cl, 3 dwg, 3 ex
