Abstract
A method and apparatus for continuously stream treating molten metal is disclosed. A controlled vortex flow of the molten metal is stimulated and a stream of particulate treating agent, such as magnesium ferrosilicon, or pure magnesium mixed with other ferro alloys, is directed onto a predetermined zone of the vortical flow. A stream choke is employed downstream of the vortex flow to control dwell time of the flow in the vortex and to regulate downstream mixing. This method increases magnesium recovery, provides flexibility to change charge weights, eliminates residue in treating apparatus, and promotes dissolution of the treating agent within a desired zone.
