摘要： Apparatus is provided for removing or disrupting a blockage from the pour opening (11) of a molten metal containment vessel (10). The vessel has an elongated conduit (20, 21) extending from the pour opening outwardly of the vessel for passage of molten metal from the vessel via the pour opening and the conduit to an outlet of the conduit; and the apparatus comprises a gas conduit (31, 36) connectible to a supply of pressurised gas (48) (e.g. oxygen or an inert gas) and extending into the molten metal conduit through the outlet of said conduit to provide a barrel (31) which is secured in said conduit and aimed at the pour opening (11); and a projectile (32) loaded in the barrel and, on admission of pressurised gas to the gas conduit, propellable towards the pour opening to impact on any blockage therein. The projectile may comprise a leading end portion comprising material adapted to generate a chemical reaction to facilitate removal or disruption of the blockage.

摘要： Metal teeming apparatus comprises a molten metal supply vessel or ladle (10) a receiving vessel or tundish (18) and a submerged pouring tube (16) fitted to an outlet (14) of a gate valve (12). The pouring tube (16) has a venting duct (25) for exhausting entrapped air from the tube when the valve (12) is first opened to commence a teem. The duct (25) is generally U-shaped. It has one limb (26) extending out of the discharge end (20) of the tube (16) and another limb (27) extending alongside the tube to a position above the metal (M) in vessel (18). A downturned part of the limb (27) has an air outlet while the limb (26) has air inlets (36) in its wall. Anchors (40) which secure the limb (26) in the pouring tube (16) protect the inlets (36) from ingress of molten metal at the onset of teeming.

摘要： Teeming control apparatus (10) comprises an outlet duct (15) installable e.g. in a tundish (11) and providing at least one exit opening (24). Movable in the duct is a valve member (16) having an enlargement (20) at one end cooperable with a valve seat (18) at the mouth or inlet end of the duct, to open or close the duct (15) to entry of melt from the tundish. The valve member (16) is configured at its other end (26) so as to vary the effective size of the exit opening(s) (24) and thereby provide control over the teeming flow rate from the apparatus.

摘要： Flow of molten steel from a tundish to a continuous casting mould is controlled by a sliding gate valve (10). The gate valve comprises a stationary refractory member (14) having a metal pouring orifice (18) and a slidable refractory member (37) also having a metal pouring orifice (42) and movable between an open condition in which its orifice (42) is aligned with the orifice (18) of the stationary member, and a closed condition in which the two orifices are out of alignment. Freezing of molten steel at the sliding gate valve when it is closed is prevented by imparting an incremental stepping motion to the slidable member (37) in its closed condition.

摘要： The invention relates to a sliding gate valve (10) for controlling the flow of molten metal from a vessel (12). The valve (10) comprises an orificed fixed plate (14) and an orificed sliding plate (15) slidingly mounted on a hinged support sub-assembly (18, 22). The sliding plate (15) is biased into face to face contact with the fixed plate (14). The biasing means (25, 26) applies the biasing force directly on to the contact plane defined by the meeting faces of the two plates (14, 15).
