Abstract

Fremgangsmåte og apparat for forbedring av dispergeringen av flussmiddelgass ved behand- ling av smeltet aluminium ved å øke overflate- arealet for flussmiddelgassen. Fremgangsmåten omfatter anvendelse av et smeltet legeme av aluminium og en gassdispergeringsenhet i le- gemet av smeltet aluminium, hvor dispergerings- enheten har minst to, nemlig evre og nedre, dispergeringsanordninger (rotorer) som er mon- tert på en aksel som strekker seg inn i det smeltede aluminium. Dispergeringsenheten ro- teres og samtidig med rotasjonen settes en flussmiddelgass til det smeltede aluminium nær den nedre dispergeringsanordning. Flussmiddel- gassen dispergeres ved hjelp av den nedre dis- pergeringsanordning slik at det tilveiebringes finfordelte bobler og disse gjendispergeres ved hjelp av den øvre dispergeringsanordning for effektivt å øke overflatearealet for flussmid- delgassen i det smeltede legeme.
