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.
