Abstract

Ved en fremgangsmåte og en anordning til anodeskifting ved aluminiumelektrolyse i smeltebad under varmegjenvinning blir de på anodestengene (7) anordnede nye karbonanoder (10) forvarmet under utnyttelse av varmen fra de restanoder (21) og/eller det varme badmateriale (30) som er tatt ut av smeltebadet, og deretter tilført smeltebadet i forvarmet tilstand. Til varmegjenvinning og varme-;, veksling kan der anvendes en varmeveksler bestående av et flerkammersystem.
