摘要： An electrode for production of aluminium metal by electrolysis of an aluminium containing compound dissolved in a molten electrolyte, where the electrowinning process is performed in smelting cells of conventional Hall-Hèroult design. The electrode comprises a calcinated carbon containing body being integrated with at least one composite metallic conductor comprising conducting elements of a Fe containing material and conducting elements of a Cu containing material. The composite conductor comprises a barrier layer material at the interface between the two conducting materials. Barrier materials of ceramic, Refractory Hard Materials (RHM), and of metallic types are proposed as well as methods for their application.

摘要： An electrolysis cell of Hall-Héroult type for producing aluminium having prebaked anodes of a carbonaceous material, and a cathode structure comprising a pot shell made out of a steel material and further having a bottom and sides supported by structural elements such as cradles and beams, wherein the cathode structure further comprises a protective and insulating lining inside the shell and a carbon based cathodic bottom with collector bars embedded therein, and where produced aluminium metal forms a layer onto said cathodic bottom, an electrolytic bath positioned above said aluminium metal where the anodes are in electrical contact with said electrolyte, wherein at least part of the steel pot shell and/or deck plates are made of a ferritic stainless steel (FSS) material. The method relates to a repair procedure for replacing parts of a commonly used carbon steel material with ferritic stainless steel material at least in parts of the steel pot shell and/or deck plates heavily exposed to corrosion and detonation. The replacement procedure can either result in a homogenous or composite material structure in affected areas.
