Abstract
Method and apparatus for adding solids to molten metal by continuously feeding both the solids and the metal into a vortex forming chamber from which the mixture is discharged at the core of the vortex as a free-falling, hollow-centered stream.
Claims5
A method for adding solid additives to molten metal comprising:
- feeding a stream of molten metal continuously into a vortex forming zone in such manner that the flow of metal in said zone is caused to rotate and to form a hollow-centered vortex, said method being characterized by:
- (1) continuously feeding the solid additive to be admixed with the metal onto the surface of the rotating metal vortex,
- (2) discharging the metal-additive mixture from said vortex forming zone in a controlled manner such that the mixture forms a free-falling, hollow-centered fluid stream, said stream remaining hollow-centered for its entire length, and
- (3) collecting the discharged mixture in a receiving zone.
