Abstract

1. Installation for melting aluminium or aluminium alloys or for keeping them in a molten state, comprising a container for molten aluminium and an electric circuit with an element immersed in the aluminium, this element consisting of a material with a higher melting point than aluminium, characterised in that the element consists of silicon carbide or graphite and the circuit is operated at a low voltage of about 5 to 15 volts.
