Abstract

The invention provides an electromagnetic brake (4) at the outlet channel (2) of a melting furnace or a vessel containing molten metal to brake or stop the flow of molten metal (3). A magnetic field (7) is imposed perpendicularly to the flow of molten metal (3) through the outlet channel (2) and an electric current (11) also can be imposed perpendicularly to the magnetic field (7) and to the direction of flow (3) in order to reduce or stop the flow of molten metal.
