ELECTRIC CURRENT LEAD UNIT OF ALUMINIUM CELLS Russian patent published in 2001 - IPC

Abstract RU 2165482 C2

FIELD: equipment for aluminium production. SUBSTANCE: electric current lead unit of aluminium cell includes steel and aluminium portions mutually joined through bimetallic adapter made by explosion welding. Novelty is wavy surface of interface steel-aluminium in bimetallic adapter. Said surface is formed by means of alternating linear protrusions at side of steel and aluminium portions of adapter. Relation of height to total thickness of steel and aluminium protrusions is in range 0.5-2; height consists 0.2-0.5 of thickness value of aluminium portion of adapter. Protrusions on interface surface are in the form of dovetails. EFFECT: enhanced operational reliability of current lead, its increased useful life period, lowered energy losses. 3 cl, 2 dwg
