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 outlet 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.

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: An apparatus is disclosed for use in replacing a worn pouring pipe by moving a pouring pipe from a waiting position to a pouring position beneath a discharge opening of a metallurgical vessel, and for use in adjusting flow of molten metal from the metallurgical vessel through the discharge opening. For this purpose, slide rails are provided beneath the metallurgical vessel for supporting head plates of pouring pipe in the waiting position, the pouring position and a discharge position. Also, a linear actuator is provided for pushing the pouring pipe from the waiting position to the pouring position, and can be detachably coupled to the head plate of the pouring pipe so that it can move the pouring pipe in opposing direction to adjust the flow of molten metal through the discharge opening between zero flow and full flow. A base plate can be optionally provided between the metallurgical vessel and the head plates of the pouring pipe, and a second linear actuator can be provied for sliding the base plate relative to the discharge opening of the metallurgical vessel and/or relative to the head plate of the pouring pipe in the pouring position.

Abstract: An apparatus for closing and/or regulating the discharge or tapping of molten metal from a metallurgical vessel includes a refractory outer pipe member having therethrough a discharge passage defining outer and inner openings and a refractory inner pipe member positioned within the outer pipe member, the inner pipe member having therethrough a passage defining outer and inner openings. A first of the pipe members is movable with respect to a second of the pipe members between open and closed positions. In the opened position, the discharge passages of the pipe members are aligned to define a molten metal discharge channel for passage therethrough in a flow direction of molten metal from an inlet opening to an outlet opening of the discharge channel. The cross-sectional area of the discharge channel is a minimum at the inlet opening and is increased between the inlet opening and the outlet opening.

Abstract: A process of making carbon-bonded refractory shapes by preparing a mix of refractory materials, pitch or tar and a binder resin, molding the mix into shapes and hardening the shapes. A starting mix is used which, based on the added quantity by weight of pitch or tar, contains 1 to 10 weight % of hollow fibers. The refractory shapes have the advantage that they exhibit less cracking, and hardly any, or even no, breaking occurs during their fabrication.

Abstract: A closing and/or regulating apparatus for tapping molten metal from the interior of the metallurgical vessel includes an inner refractory pipe having extending through a wall thereof at least one opening and an outer refractory pipe fitted over the inner pipe and having extending through a wall thereof at least one opening. Outer and inner surfaces of the inner and outer pipes, respectively, define mating sealing surfaces. One of the pipes is fixedly mounted to a metallurgical vessel, and the other pipe is movable axially and/or rotatably relative to the one pipe to thereby selectively bring the openings to the two pipes relatively into and out of alignment. The inner pipe has adjacent an inner end thereof at a position inwardly of the opening therein a closure closing the interior of the inner pipe. The outer pipe defines therein a space forming a gas distribution chamber at a location confronting the closure. A gas, for example an inert gas, is introduced into the gas distribution chamber such that the gas passes therefrom between the sealing surfaces and into the openings.

Abstract: A closing and/or regulating apparatus for tapping molten metal from the interior or a metallurgical vessel includes a vertical inner pipe having extending through a wall thereof at least one opening for the passage of molten metal. An outer pipe is fitted over the inner pipe and has extending through a wall thereof at least one opening. One of the pipes is to be mounted stationarily with respect to a metallurgical vessel, and the other of the pipes is displaceable relative to such one pipe in a vertical axial direction through a working stroke at which the openings of the pipes may be brought into alignment to thereby discharge molten metal downwardly through the interior of the inner pipe. The dimension of the opening in the stationary pipe in such direction is greater than the dimension of the opening in the displaceable pipe in such direction. The circumferential dimension of the opening in the displaceable pipe is substantially the same as the circumferential dimension of a lower portion of the opening in the stationary pipe.
