    摘要: A method and product improve the positioning of loose anti-skulling material in the outlet nozzle zone of a metallurgical pouring vessel. The formation of skull in the outlet nozzle zone of a metallurgical pouring vessel is inhibited by positioning in the outlet nozzle zone an elongated container containing loose anti-skulling material, the container being formed of an intumescent material so that when heated it expands to fill the gap between itself and the walls of the nozzle and releases the anti-skulling material.

    摘要: An insulation sheath for a pipe in a furnace is provided. The sheath has excellent insulation properties together with adequate resistance to the corrosive environment and thermal shock conditions. A pre-formed, substantially C-shaped, elongate member shaped to conform to the pipe over a portion of its circumference, the member comprising an inner layer of bonded insulating material integrally-bonded to a protective outer layer of refractory material. The inner layer is preferably formed of bonded ceramic fibre.

    摘要: An exothermic composition comprises a particulate readily oxidizable metal such as aluminum, magnesium or silicon and an organic fluorine-containing compound, and usually an oxidizing agent for the readily oxidizable metal. The preferred organic fluorine-containing compound is polytetrafluoroethylene. The composition may also contain a binder, a particulate refractory material, refractory fibres and/or organic fibres. The composition may be used in the casting of molten metal, either in particulate form or as a preformed shape such as a sleeve or board, to cover or surround molten metal in the feeder of a casting mould or in the head or head box of an ingot mould.

    摘要: The invention relates to a means of purifying molten metal, particularly steel, by the removal of impurities/inclusions during continuous casting.The molten metal (3) is passed in a tundish (1) through a vertical array of baffles (8) that are spaced apart transversely across the tundish to provide restricted flow channels (12). The baffles (8) may be flat boards or tiles (9a, 9b) and are preferably used in contact with a weir (7) and dam (10), upstream and downstream respectively of the baffles.The speed and direction of flow of the molten metal can thereby be controlled and directed to give more effective dwell time in contact with a surface covering layer (11) of flux.
