ABSTRACT:
Process and apparatus for improving fluxing gas dispersion in treating molten aluminum by increasing the fluxing gas surface area. The process includes the use of a molten body of aluminum and a gas dispersing unit in the body of molten aluminum, the dispersing unit having at least two, upper and lower dispersers (rotors) mounted on a shaft extending into the molten aluminum. The dispersing unit is rotated, and simultaneously with the rotating, a fluxing gas is added to the molten aluminum adjacent the lower disperser. The fluxing gas is dispersed by the lower disperser to provide finely divided bubbles and then re-dispersed with the upper disperser to effectively increase the fluxing gas surface area in the molten body.
