摘要： An article of refractory hollowware for use in a runner assembly for casting molten metals e.g. ferrous metals, has at least one inner surface adapted to increase the internal surface contact area of the article. The surface is so arranged as to effect at least two abrupt changes of direction of flow of molten metal flowing through the article. Use of the article minimizes the level of non-metallic inclusions in ingots and castings.

摘要： A sealing structure is disposed between a metal-casting ingot mold bottom portion and a bottom plate to prevent the leakage of molten steel between the mold and plate. A clay rope disposed in a closed configuration corresponding to the bottom of the ingot mold is affixed to the cardboard sheet with an adhesive system. Overlapping portions of the cardboard sheet are grasped to position the clay rope directly under the ingot mold, and the mold is lowered onto the bottom plate. Hot glue (or pressure sensitive adhesive tape and/or white glue) holds the clay rope on the cardboard sheet. The clay rope is offset at a central portion of the sheet to allow folding of the sheet for transport.

摘要： A method of purifying steel in a tundish, especially to remove alumina inclusions, comprises passing the steel through at least one refractory board having apertures through it and introducing inert gas into the steel at the upstream side of the foot of the board to cause a stream of bubbles to flow over the upstream side of the board. One of the boards may comprise a ceramic filter element. The boards may be non-vertical and have integral gas supply means. The apertures may taper, may have axes angled from perpendicular to the board's plane and may have high alumina content surfaces. The upstream side of the board may have an exothermic layer.

摘要： A rotary device for dispersing a gas in molten metal, for example argon in molten aluminium, contained in a vessel, comprises a hollow shaft and a hollow rotor fixedly attached to the shaft, the rotor having a plurality of vanes each extending from the shaft, or a location adjacent the shaft, towards the periphery of the rotor whereby the hollow interior of the rotor is divided into a plurality of compartments, at least one aperture in the top or bottom of the rotor adjacent the shaft and at least one aperture in the peripheral surface of the rotor such that when the rotor rotates molten metal can enter each of the compartments through the aperture or apertures in the top or bottom, and flow outwardly through the peripheral aperture or apertures and at least one duct for the passage of the gas extending from the hollow interior of the shaft to each of said compartments. The gas and molten metal are mixed together within the rotor and on emerging from the rotor the gas is dispersed throughout the body of the molten metal as a stream of very small bubbles.

摘要： A particulate flux composition suitable for desulphurizing and/or dephosphorizing molten ferrous metals and for use as a mould flux comprises prefused particles comprising calcium oxide and at least one other component, such as alumina, iron oxide, calcium fluoride, magnesium fluoride, sodium fluoride, silica, sodium oxide, zirconium oxide, titanium oxide or sodium borate, and in which each particle has a substantially vitreous amorphous structure. The composition is highly resistant to hydration and does not introduce hydrogen into the molten metal.

摘要： A method of sealing a joint between component parts of a metal mould for metal casting comprises applying in the area where the seal is desired an elongated sealing element and a compressible cover separating the sealing element from each of the surfaces to be sealed together. The method is especially useful for sealing the joint between an ingot mould for steel ingots and a base plate for the mould.

摘要： A seal between an ingot mould and a base plate or between a head-box and an ingot mould is formed from a pack of flat, flexible strips, for example, of cardboard or aluminium interlinked at spaced intervals along the strips. The joints between any one strip and an adjacent strip next to one face thereof are staggered in relation to the joints between the one strip and the adjacent strip next to the other face thereof. The pack is expanded lengthwise to separate the strips where they are unjoined and form generally hexagon shaped cells and is then placed on the base plate with the longitudinal edges of the strips of the pack on the base plate. The expanded pack is arranged lengthwise into a closed figure corresponding to the shape of the ingot mould. The ingot mould is then placed on top of the expanded pack which is crushed between the ingot mould and the base plate to form the required seal. A head-box seal is similarly made between the top face of the ingot mould and the head-box.
