Abstract
Sealing devices are provided as configured for use with cathode devices of an electrolytic cell for production of aluminum. In particular, the seals are specifically configured to provide an outlet seal for the cathode bars. The sealing devices are made of a material that is elastic, gas-proof, and heat-proof, and can create a hermetic seal around the cathode bar in such a way as to be able to move synchronously or asynchronously with the movement of the cathode bar as it undergoes thermally induced movement during aluminum production.
