PCT No. PCT/AU92/00599 Sec. 371 Date Apr. 22, 1994 Sec. 102(e) Date Apr. 22, 1994 PCT Filed Nov. 6, 1992 PCT Pub. No. WO93/09274 PCT Pub. Date May 13, 1993.A support structure for supporting continuous prebaked anodes in an aluminium smelting cell comprises a pair of side plates (3) and a pair of end plates (4) connected together to form an enclosed superstructure. The supporting structure includes at least one pair of spaced cross-plates (8, 9) that are configured to provide wedging surfaces which act to support an anode (14) therebetween. Electrical current is fed to the anodes via the cross-plates. Respective pairs of cross-plates supporting adjacent anodes may be spaced to define heat exchange passages which can be used to control the temperature of the support structure. A method for operating an aluminium smelting cell at variable amperage by positive and controlled extraction of heat from the cell is also described.
