摘要： An impact pad (20), formed from a refractory material capable of withstanding contact with molten metal, comprises a base (12) serving in use as an impact surface for molten metal, and a sidewall (14) extending generally upwardly therefrom. The sidewall (14) terminates at an upper surface (16) which is above the base (12) in use such that the base (12) and sidewall (14) define a receptacle for receiving molten metal. The sidewall (14) contains therein at least one channel (22), the at least one channel (22) having first and second ends (24, 26); the first end (24) being relatively closer to the base (12) at its intersection with the sidewall (14) than the second end (26). The at least one channel (22) being open ended at the second end (26) or tapering such that the at least one channel (22) has zero depth at its second end (26). The invention also relates to a tundish including an (15) impact pad (20) as described above.

摘要： The invention relates to a mixing chamber (10) for use in a metal transfer vessel (for example, a tundish used in steel manufacture or a holding furnace used in aluminium manufacture). The mixing chamber comprises a base with a first series of wall components (14,16,18,20) defining a first mixing zone (22) and a second series of wall components (28, 30). A second mixing zone (56,58) is defined between at least one of the second series of wall components (28,30) and at least one of the first series of wall components (14,16,18,20). A continuous flow path is provided from the exterior of the mixing chamber to the first mixing zone, from the first mixing zone to the second mixing zone, and from the second mixing zone to the exterior of the mixing chamber. The region of the flow path between the first mixing zone and the second mixing zone being defined by a first cut-out (42) in at least one of the first wall components (28,30) and the region of the flow path between the second mixing zone (56,58) and the exterior of the mixing chamber being defined by a second cut-out (64,66) in at least one of the second wall components. The first cut-out (42) is spaced from the base and the first and second cut-outs are mutually spaced along the flow path within the second mixing zone such that in use the general directions of flow within the second mixing zone and between the first and second mixing zones are different.

摘要： A stopper rod comprises an elongate body having an inlet at an upper first end and an outlet at a lower second end. The second end of the body defining a nose for insertion into a tundish outlet. A continuous axial bore extends through the body from the inlet in the first end to the outlet in the second end. A restrictor having an inlet, an outlet and a passageway therebetween, is positioned in the axial bore such that the inlet of the restrictor is closer to the first end than the second end. A gas supply conduit is arranged to supply gas into the axial bore above the inlet of the restrictor.

摘要： A nozzle (410) for guiding molten metal comprises an inlet (106) at an upstream first end and at least one outlet (210) towards a downstream second end. An inner surface (117) is provided between the inlet (106) and the at least one outlet (210) to define a bore (118) through the nozzle (410). The bore (118) has a throat region (200) adjacent the inlet (106). An annular channel (420) is provided in the inner surface of the nozzle (410). A fluid supply means (900) is arranged to introduce fluid into the bore (118) via the annular channel (420) or downstream thereof. The throat region (200) has a convexly curved surface and the annular channel (420) is located within or adjacent the throat region (200). The invention also provides for a method of controlling the flow of molten metal through a nozzle (410), as described above, and a system for controlling the flow of molten metal. The system comprises a nozzle (410), as described above, and a stopper rod (100) configured to be received in the throat region (200) of the nozzle (410) to control the flow of molten metal through the nozzle (410).
