摘要： There is disclosed a continuous casting process in which contaminants from a metal melt are separated out by forcing the metal melt to undergo a rotating turbulent flow before it is cast. The desired rotating turbulent flow is achieved by disposing a suitable chamber, through which the melt flows, between the ladle and the mould.

摘要： A method of and apparatus for handling liquid steel in a tundish preparatory to teeming the steel into a continuous casting mold. Initially the tundish outlet is closed with a slidable gate which has a porous plug aligned with the outlet. Inert gas is injected into the steel through this plug to agitate the steel in the region of the tundish outlet. Inert gas injection is terminated shortly before the commencement of teeming, and oxygen rich gas is injected to react exothermically with the steel in the nozzle well area. Thereafter the porous plug slidable gate is replaced with a conventional gate having a teeming opening.

摘要： A tundish with improved flow characteristics for molten metal has an outlet in its base. The outlet is spaced longitudinally in the tundish from a pour zone. The pour zone is positioned to receive a stream of molten steel from a ladle. The outlet is provided with a refractory barrier at its upper end. A portion of the floor of the tundish circumferential to the outlet is provided with a refractory structure having an interior free volume. Structures within the tundish, such as a dam extending upwardly from the tundish floor between the pour zone and the outlet, or a well in the tundish floor surrounding the outlet, may be used to affect the flow of molten metal in the tundish.

摘要： An annular weir is fixed at a bottom of a tundish and just under a long nozzle of a ladle in a continuous casting apparatus. The annular weir includes a cavity which has a substantially circular shaped transverse section. The cavity includes: an upper side opening configured to receive a stream of molten metal from an upper side through the long nozzle; an inner protrusion which is annular in shape and which extends toward an inner side from an upper end of an inner wall of the cavity; a first space on an inner side of the inner protrusion; and a second space which communicates with the first space 13a and which is on a lower side of the first space.

摘要： A hot-top is disclosed that continuously casts an ingot by pouring molten metal down into a cylindrical space in a continuous casting mold from a molten metal flow-down port. The inner shape of a flow-down port forming part corresponds to the inner shape of a cylindrical space forming part. The hot-top forms an annular groove about the molten metal flow-down port, and has a barrier between the annular groove and the flow-down port.

摘要： A continuous casting tundish has a horizontal baffle intermediate its height. The baffle has a hole therethrough, to receive the downward flow of molten steel from the snorkel of a ladle, which flow educts steel through the hole and with it any desired additives such as alloying and/or refining agents. The space below the baffle is of lesser cross sectional area than the space above the baffle, and at least one end of the space below the baffle communicates with the space above the baffle, so that circulating flow of steel through the hole, below the baffle, and back over the baffle and again through the hole, is induced, that flow being turbulent below the baffle and laminar above the baffle. The tundish has the usual casting holes in its bottom.
