    Abstract: An immersion nozzle includes an immersion zone inserted into a long-thin mold cavity of a mold. A discharge channel extends through the nozzle for discharging molten metal into the mold cavity. The discharge channel includes an inlet region, an outlet region including a portion passing through the immersion zone, and a pool-forming chamber between the inlet region and the outlet region at a location adjacent the immersion zone. The portion of the outlet region of the discharge channel that extends through the immersion zone is widened and has a configuration to approximate the cross-sectional configuration of the mold cavity. The outlet region has, extending from the chamber in a direction of material flow, a configure approximately corresponding to the configuration of the portion of the outlet region through the immersion zone.

    Abstract: A rotary valve for controlling the discharge of molten metal from a metallurgical vessel includes a refractory rotor having a cylindrical outer peripheral surface and fitted within a recess defined by a cylindrical inner surface in a refractory stator and complementary to the outer surface. The rotor may be rotated about either a horizontal or a vertical axis relative to the stator and may be axially moved within the recess therein. The rotary valve may be mounted on the exterior of a bottom wall of a metallurgical vessel or alternatively may be mounted within a refractory lining of the metallurgical vessel, particularly in a transition area between a side wall and a bottom wall of the metallurigcal vessel. Further alternatively, the rotary valve may be mounted within the refractory lining of the bottom wall of the metallurgical vessel, with the rotor extending through the bottom wall and being actuated for movement from below the bottom wall.

    Abstract: The present invention is drawn to a regulating device of a metallurgical vessel for regulating the flow of molten metal from the vessel. The device includes a fixed refractory part defining a first cylindrical peripheral surface of the device and a movable refractory part that is rotatable and/or slidable relative to the fixed refractory part and defines a second cylindrical peripheral surface sealingly engaged with the first cylindrical peripheral surface. An actuating device is connected to the movable refractory part for rotating and/or sliding the movable refractory part relative to the fixed refractory part. The cylindrical peripheral surfaces of the refractory parts are spaced apart from one another so as to define an annular gap therebetween. In order to ensure that during operation the refractory parts can be moved relative to one another by the actuating device while preventing the penetration of molten metal into the annular gap, each of the refractory parts has a coefficient of thermal expansion which, when the device is subjected to a high temperature corresponding to the melting temperature of a molten metal, causes a clearance fit to be established between the peripheral surfaces that is effective to prevent molten metal having a melting point at the same predetermined high temperature from penetrating between the peripheral sealing surfaces while allowing the movable refractory part to be moved relative to the fixed refractory part.

    Abstract: A rotary valve for controlling the discharge of molten metal in a substantially downward direction from a metallurgical vessel includes a refractory rotor rotatable about a substantially horizontal axis. The rotor has an outer peripheral surface, either conical or cylindrical, arranged symmetrically about the axis, and the rotor has therethrough a flow channel having inlet and outer ports, at least the outlet port opening onto the outer surface. A refractory stator has therein a recess defined by an inner surface, either conical or cylindrical, complementary to the outer surface of the rotor, the stator having therethrough a discharge channel. The rotor fits within the recess in the stator, with the outer and inner surfaces thereof being complementarily positioned symmetrically about the axis. The stator and rotor are arranged in the region of the metal melt in the interior of a metallurgical vessel in and/or on the refractory lining of a side wall of the vessel and/or the refractory lining of the bottom of the vessel.
