Abstract

En anordning for injisering av gass i smeltet metall, eksempelvis aluminium, i et ovnskanuner omfatter: (a) et røreapparat med et reservoarkammer adskilt fra ovnskammeret, en tilknytningsdel med en åpning som forbinder det indre av ovnen og reservoaret for føring av smeltet metall derimellom via tilknytningsanordnin- gen, vakuura/trykk-genererende midler forbundet med reservoarkammerets indre for vekselvis og i rekkefolge å produsere vakuum for å trekke smeltet metall inn i det indre av ovnskammeret og et positivt trykk for å utstøte det smeltete metall derfra og inn i ovnskam- meret gjennom åpningen i form av en høyhastighetsomrø- ringsstråle, og (b) en gassinjektoranordning tilpasset for å innføre gass i høyhastighetsstrålen, slik at gassen brytes opp i et stort antall små bobler som sirkulerer gjennom ovnskammeret med rørestrålen.An apparatus for injecting gas into molten metal, for example aluminum, in a furnace gun comprises: (a) a stirrer having a reservoir chamber separate from the furnace chamber, an attachment member having an opening connecting the interior of the furnace and the reservoir for passing molten metal therebetween. the connection means, vacuum / pressure generating means connected to the reservoir chamber interior to alternately and sequentially produce vacuum to draw molten metal into the interior of the furnace chamber and a positive pressure to eject the molten metal therefrom and into the furnace chamber and (b) a gas injector device adapted to introduce gas into the high-speed jet, such that the gas is broken up into a large number of small bubbles circulating through the furnace chamber with the stirring jet.
