Abstract
The invention relates to a method for removing inclusions of foreign matter (for example slag inclusions) from a bath of molten metal. The method is characterized in that molten metal located in a bath in a vessel is rotated about a vertical axis by means of at least one electromagnetic stirrer, to cause the inclusions to move towards the center of the vessel where they agglomerate and float up to the bath surface. Molten metal substantially free from inclusions can then be tapped off from a lower part of the vessel, to one side of said axis.
