Abstract (en)
[origin: WO2004027119A2] The invention relates to a method for pre-heating a stack (1) provided with anodes (10) and cathodes (5) for electrolysis aluminium production. Said method comprises a first stage which is carried out prior to power supply to the stack when a layer of granulated conductive material is placed and crushed between anodes and cathodes. Said invention is characterised in that the granulated conductive material is graphite-based and the crushed layer thereof extends in the form of fixed contacts (13) only on the part of the top surface (14) of each anode.
