Abstract

A method and its corresponding apparatus for the treatment of a stream of molten metal by introducing a reaction additive into said stream, in which said additive is caused to fall on said metal either while or just before causing a vertex in said stream. Of molten metal, the additive being dragged under the surface of the molten metal and reacting with it, effecting this process in an airtight container.
