Control of temperature and operation of inert electrodes during production of aluminium metal

摘要: The present invention relates to methods for operating and controlling the temperature of inert electrodes during production molten aluminium by electrolysis an aluminous ore, preferably alumina, dissolved in salts, a fluoride based electrolyte, cell with vertical or essentially electrode configuration. describes designing and/or inclined position metal, where said have that may deviate from electrolyte temperature, thereby dissolution materials preventing solid deposit formation on electrodes. is also applicable cells utilising horisontal configuration, traditional Hall-Heroult retrofitted anodes.
