Abstract

See full text

An aluminum smelter comprising:

    (i) a series of electrolytic cells, designed for the production of aluminum, forming one or more rows,(ii) a supply station designed to supply the series of electrolytic cells with an electrolysis current,the said electricity supply station comprising two poles,(iii) a main electrical circuit through which the electrolysis current flows, having two extremities each connected to one of the poles of the supply station,(iv) at least one secondary electrical circuit comprising an electrical conductor made of superconducting material through which a current flows, running along the row or rows of electrolytic cells,characterized in that the electrical conductor made of superconducting material in the secondary electrical circuit runs along the row or rows of electrolytic cells at least twice in such a way as to make several turns in series.
