Abstract: A furnace plant which at least one furnace vessel with side walls and a bottom and at least one heat source which by radiation and convection heats molten metal and/or solid metal present in the furnace vessel. At least one two- or multiphase electromagnetic side stirrer is arranged in or near the wall of the furnace vessel to act through the wall and apply a stirrer field to the molten metal. The side stirrer comprises at least two phase windings arranged around an iron core having a vertical extent, H, which essentially covers the region, D.sub.max, between the bottom and the upper surface of the molten metal at a maximum bath depth used in the furnace 15 vessel. The side stirrer is arranged with a pole pitch.tau. which exceeds twice the distance from the iron core to the molten metal, .tau.>2 dw.

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.
