ALUMINUM CELL SELF-FIRED ANODE FORMING METHOD Russian patent published in 2007 - IPC C25C3/12 

FIELD: metallurgy of aluminum, possibly in plants for producing aluminum having aluminum cells with self-fired anodes and upper electric current lead.

SUBSTANCE: method for forming self-fired anode of aluminum cell with upper electric current lead and with lengthwise rows of anode pins connected to anode bus comprises steps of charging main and correcting anode masses onto surface of self-fired anode; extraction of anode pins; placing plugs in craters and placing anode pins onto upper level of self-fired anode. Plugs of anode mass containing binder in quantity 13 -30% and secured to lower base of anode pins are placed in said craters. Anode pins are connected to anode bus after melting plugs and after arranging them by gravity action onto upper level.

EFFECT: lowered labor consumption for replacing anode pins, reduced content of binder in under-pin mass, decreased outbursts of resinous matters to environment.
