Abstract

1431622 Cathode block assemblies for fused electrolyte cells SWISS ALUMINIUM Ltd 5 Feb 1974 [9 Feb 1973] 05310/74 Heading C7B A cathode block assembly, for a fused electrolyte cell e.g. containing a charge of alumina dissolved in molten cryolite, comprises a carbon block 1 having a groove 2 in which lies a conductive bar 3, each side 4, 5 of the groove having at least one recess 6, 7, and a cast iron mantle 10 which lies in the space (11) between the bar and groove surfaces 4, 5, 14 and has a projection 13 extending into each recess to anchor the mantle in the block.
