Bubbling Behaviour in Molten Metals

Recent cineradiographic observations of gas injection into liquid metals plus bubble frequency measurements are used to develop a sequential mechanism for bubble growth and release from non-wetted nozzles at low gas flow rates. The bubble volumes at release are consistent with results in iron-carbon alloys over a wide range of variables, and are much larger than would be expected on the basis of aqueous systems. This is because all previous …
