Abstract
An elongated nozzle assembly for closing and/or regulating the discharge from a metallurgical vessel of molten metal in the form of a wide strip includes refractory tubular stator and rotor members each having extending through a tubular wall thereof a discharge opening in the form of a slot elongated in the direction of coincident longitudinal axes thereof. The stator and rotor members are assembled with one member fitting in a sealing manner within the other member, thus forming inner and outer members. The inner member has therein a cavity elongated in the direction of the axes of the members and into which opens the discharge opening of the inner member. A first longitudinal end of the cavity is closed by an end wall of the inner member. A second longitudinal end of the cavity is opened axially through an inlet opening in the respective longitudinal end of the inner member. The inlet opening communicates via the cavity with the discharge opening of the inner member.
