FIELD: electricity.
SUBSTANCE: invention relates to a design of electrolyzers anode pin with a self-baking anode and an upper current lead in electrolytic production of aluminium. Anode pin comprises a steel cylindrical rod, the outer surface of which has a thread, herewith the outer surface of cylindrical part of the pin immersed in the anode is made with a tubular thread with pitch P equal to 0.2÷0.5 of length L of the anode pin, herewith the ratio of outer diameter D of the anode pin to inner diameter D1 of a cylinder inscribed by the inner thread top is within D:D1=1:0.9÷0.6, while the number of turns of the thread n ranges from 2 to 4.
EFFECT: provided is reduced power consumption for aluminum production by reducing voltage drop in the contact node of anode pin-anode due to increasing its square, reducing the force required to be applied at screwing the pin out of the anode, excluding destruction of the sintered part of the anode at extraction of the pin.
