Abstract (en)
[origin: US4494735A] A gas injection nozzle design for use in a swirling tank reactor used in the degassing of molten metal with a fluxing gas. The nozzle design eliminates metal leakage from the reactor around the nozzle tip and gas leakage within the fluxing gas delivery line. The nozzle tip is provided with an orifice profile consisting of a straight hole opening of constant diameter or consisting of a converging-diverging profile.
