Title:
ALUMINIUM SMELTER COMPRISING ELECTRICAL CONDUCTORS MADE FROM A SUPERCONDUCTING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/007894
Kind Code:
A3
Abstract:
The invention relates to an aluminium smelter (1) comprising: (i) a series of electrolytic cells (2) intended for the production of aluminium, forming one or more rows (F); (ii) a power-feeding station (12) intended to supply the series of electrolytic cells (2) with electrolysis current (I1), said power-feeding station (12) comprising two poles; (iii) a main electric circuit (15) through which the electrolysis current (I1) flows, said electric circuit having two ends each connected to one of the poles of the power-feeding station (12); and (iv) at least one electrical conductor made from a superconducting material. The aluminium smelter is characterised in that the superconducting electrical conductor is placed fully or partially inside a chamber (20) forming a magnetic loop.
