    摘要： A rotary device and methods for treating molten metal, a tubular sleeve for said rotary device and the use of said rotary device in the treatment of molten metal. The rotary device comprises: a tubular sleeve comprising a rotor head at one end, the rotor head comprising a gas outlet for dispersing gas into molten metal; and a hollow shaft extending inside the tubular sleeve such that at least a portion of the hollow shaft is enclosed by the tubular sleeve, wherein the hollow shaft is fluidly connected to the gas outlet of the rotor head, the tubular sleeve is formed from a refractory material that is resistant to corrosion and thermal shock, and the hollow shaft is formed from a material comprising graphite. A first method comprises: applying a layer of synthetic slag material onto an exposed surface of the molten metal; and stirring the molten metal using a rotary device comprising a rotor head, such that the molten metal flows past the layer of synthetic slag material. A second method comprises: applying a metal treatment agent to molten metal; stirring the molten metal using a rotary device comprising a rotor head; and discharging gas into the molten metal through the rotor head.

    摘要： The present invention relates to a feeder element for use in metal casting. The feeder element comprises a first end for mounting on a mould pattern or swing plate, an opposite second end comprising a mounting plate for mounting on a feeder sleeve and a bore between the first and second ends defined by a sidewall. The feeder element is compressible in use whereby to reduce the distance between the first and second ends. The bore has an axis that is offset from the centre of the mounting plate and an integrally formed rim extends from a periphery of said mounting plate.The feeder element of the invention finds particular utility in high pressure vertically parted sand moulding systems.

    摘要： A stopper rod for controlling the flow of molten steel from a tundish has a metal carrier element partly received in an internal passageway of the stopper rod, the carrier element compressing sealing means between a frustoconical undersurface of a laterally enlarged portion thereof and a complementary seating surface of the stopper rod passageway, there being an insert threadedly engaged with one of the carrier element and stopper rod body at a position above a laterally enlarged portion of the carrier element, with further sealing means disposed between said insert and the carrier element. Preferably the insert is a nut screwed down onto a washer which compresses the further sealing means.

    摘要： The present invention relates to an electrochemical sensor for determining the concentration of a group IA metal in a fluid such as molten metal. The sensor comprises a substantially pure quantity of the group 1A metal as a reference electrode (13) contained in a sensor housing (3), and a solid electrolyte constituting at least part of the sensor housing (3). The electrolyte is in electrical contact with the reference electrode (13) and the sensor is capable of operating at temperatures in excess of 973K. In a preferred arrangement, the sensor comprises a two part elongate conductor (15), a first part (17) of which extends from the reference electrode (13) into a refractory seal (11a), and a second part (19) of which extends from within the refractory seal (11a) externally of the sensor, the two parts (17, 19) being welded together.
