Method for processing aluminium in a rotary or reverberating furnace

摘要: The invention relates to a method for processing aluminium in furnace consisting introducing an aluminium-containing material and possibly one or several types of salt into the furnace, melting said by heating with aid at least burner supplied combustive fuel such way that molten covered slag containing, particular alumina is produced measuring carbon monoxide and/or hydrogen concentration atmosphere smoke exit furnace. Oxygen content supplying greater than 10 % volume, preferably 21 volume. inventive also involves final phase reduction oxydation during which flow rate substantially constant while injected controlled value ranging from 3 15 volume CO without control.
