CURRENT SUPPLY LEAD TO ALUMINUM CELLS Russian patent published in 2005 - IPC

FIELD: non-ferrous metallurgy, possibly systems for sustaining operation modes of aluminum cells, mainly devices for connecting cathode bus with cathode rod of aluminum cell.

SUBSTANCE: current supply lead includes electric current supply unit in the form of set of flexible aluminum bands. One end of said set is rigidly connected with cathode bus; its other end is detachably connected with steel cathode rod through adapter whose contact surface is coated with copper layer. Current supply lead also includes additional adapter for connecting ends of set of flexible aluminum bands with cathode bus and with two metallic plates. Said adapter has П-shaped recess; ends of set of flexible aluminum bands are connected one to other, to lower planes of П-shaped recesses of adapters and to metallic plates by means of explosion welding. At side of cathode rod adapter and metallic plate are made of steel. At side of cathode bus adapter and metallic plate are made of aluminum. At side of cathode bus adapter and metallic plate are made of steel. Layer of aluminum is applied onto lower surface of adapter.

EFFECT: lowered electric current loss in place of contact of current supply lead and cathode rod, improved mechanical strength of connection.
