Abstract
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.
Claims24
A support structure for supporting continuous prebaked anodes in an aluminium smelting cell, comprising a pair of rigid side plates and a pair of rigid end plates rigidly connected to define an enclosed supporting structure, at least one pair of spaced rigid electrically conductive cross plates configured to provide wedging surfaces against which side surfaces of a continuous prebaked anode are held by clamping means supported by one of said side plates, means for introducing electrical current into said cross plates and elevating and lowering means carried by said supporting structure to facilitate proper positioning of the anode and feeding of the anodes with respect to the supporting structure.
