Abstract

See full text

The design of a metal inert anode is proposed, it is made in the form of a perforated structure with through-openings, in particular formed by longitudinal and transverse anode elements intersecting each other and limited by the lateral sides of the intersecting anode elements, and contains vertical or inclined fins that protrude from the bath and are integrated with the anode elements or a current conductor. As a result, it ensures a reduction in the voltage drop in the anode and in the bubble layer under the anode, a reduction in the anode overvoltage and anode consumption, an increase in current efficiency and the reliability of the cryolite-alumina crust, which leads to an increase in the anode service life and promotes the formation of a reliable and durable cryolite-alumina crust above the melt surface, which improves process efficiency.
