Abstract
A treatment of metal melts comprising the addition of chemically active substances or alloying elements with subsequent mixing taking place as a result of electromagnetic force exerted on the metal melt. The melt, which fills a substantially cylindrical vessel to above its half way mark, is raised to the vertex of the vessel by means of a rotational movement about the substantially horizontal axis of the vessel, and is then allowed to fall back or is conveyed back in the direction of the axis of the vessel to the surface of the melt, on which the chemically active substances or alloying elements have been introduced.
Claims10
A method for treating a metal melt by the addition of chemically active substances or alloying elements, the metal melt residing in a vessel having an apex and having a longitudinal axis which is substantially horizontal or inclined from the horizontal including the step of:
- filling said vessel above one half full with said melt to be treated;
- rotating said melt less than 360 degrees about said longitudinal axis of said vessel using electromagnetic force to thereby raise said melt to the apex of said vessel;
- causing said melt to fall back from the apex in the direction of said longitudinal axis of said vessel onto the surface of said melt while the melt is contemporaneously being raised to the apex of said vessel;
- and
- adding substances to said melt.
