CONNECTION OF BUS TO CATHODE BAR OF ALUMINUM ELECTROLYZER Russian patent published in 2003 - IPC

Abstract RU 2220230 C2

FIELD: non-ferrous metallurgy, provision for operation of electrolyzer producing aluminum. SUBSTANCE: connection of bus to cathode bar of aluminum electrolyzer has flexible cathode lowering in the form of strips made fast to bus and linked rigidly by means of releasable connection having form of fixing elements through bimetal plates to end of cathode bar which surfaces are worked for electric contact. Novelty of invention lies in manufacture of bimetal plate from steel and copper parts, strips of cathode lowering are interconnected and linked to steel part of plate by explosion welding to form single adapter in joint of cathode lowering to bimetal plate. Steel part of bimetal plate has bevel, strips of cathode lowering are connected to steel part of plate along straight surface and bevel surface. EFFECT: reduced electric losses in point of contact with cathode bar and in point of connection of cathode lowering to adapter. 1 cl, 2 dwg
