Abstract
A device for detecting slag flowing with a stream of molten metal dischar through an outlet opening in a metallurgical vessel includes a sensor positioned in the area of a base plate of the vessel to surround the stream of molten metal without being contacted thereby. The sensor has a sending coil and a receiving coil associated with a reference coil. At least the sending and receiving coils are positioned within a housing formed of a non-magnetic material. The housing encompasses the coils and defines therearound a protective casing that alters electromagnetic fields emanating from the base plate and the stream of molten metal and that is resistant to mechanical stresses.
