INTERIOR LINING SYSTEM FOR AN ELECTROLYTIC CELL

The invention relates to an electrolytic cell comprising a chamber having sidewalls including a pair of longitudinal walls and a pair of transverse walls, a cathode inside the chamber, and a side lining including an inner layer on the periphery of the cathode and an outer layer adjoining the side walls of the chamber on the periphery of the inner layer, the side lining extending vertically beyond the cathode, characterised in that the inner layer comprises segments including a nominal segment and a conductive segment arranged one after the other along a side wall of the side walls of the chamber; the nominal segment having a nominal thermal conductivity and the conductive segment having a thermal conductivity greater than the nominal thermal conductivity, the conductive segment adjoining an area of the chamber subjected to increased thermal stress. The invention also relates to a foundry comprising an electrolytic cell having the above-mentioned characteristics.
