LEAD SEALING OF CATHODE BARS OF ALUMINUM ELECTROLYZER Russian patent published in 1998 - IPC

FIELD: electrolytic production of aluminum, in particular, cathode assemblies of electrolyzers for production of aluminum, more specifically, designs of seals of cathode bars leads. SUBSTANCE: seal of cathode bar lead of aluminum electrolyzer includes sealing member round cathode bar made of self-hardening material and metal box connected to cathode shell with ports to pass cathode bars. Metal box has two openings. One opening serves to pass the cathode bar and the other, for supply of sealing member material. Located between sealing member and cathode bar is a layer of material ensuring sliding of cathode bar relative to sealing member. EFFECT: higher efficiency. 1 dwg
