摘要： A method of casting a metal alloy ingot, including the following steps: providing a one side open-ended mould including a plurality of sides and a bottom plate defining a mould cavity with a mould opening, the open-ended mould being pivotable around a horizontal rotational axis between a position so that the mould opening points upwards and a position so that the mould opening points side-wards or down-wards; positioning the open-ended mould such that the mould opening points side-wards or down-wards; providing a casting container with an upwardly positioned aperture; filling the casting container with molten metal for one casting operation; coupling the casting container to the open-ended mould so that the casting container is located below the mould while the mould opening points side-wards or down-wards; rotating the open-ended mould together with the casting container around the horizontal rotational axis for approximately 90° to 180° from a position whereby the mould opening points side-wards or down-wards to a position whereby the mould opening points upwards such that the molten metal is conveyed through the mould opening into the open-ended mould until reaching a desired thickness, whereby the molten metal in the open-ended mould is cooled directionally through its thickness where the solidification front remains substantially monoaxial.

摘要： A system for adding molten lithium and inert gas in a molten aluminium or aluminium alloy melt including, a crucible defining a chamber for melting and storing molten metal, in particular molten lithium; the crucible having a sealed lid; an inert gas delivery system for maintaining chamber overpressure using inert gas; a conduit for withdrawing a portion of the molten metal from the crucible. The conduit arranged with respect to the crucible or the sealed lid so the conduit inlet can be moved below and above the molten metal surface level and arranged for feeding molten metal from the crucible to a separate holding furnace with the help of overpressure when the conduit inlet is below the molten metal surface level and arranged for feeding inert gas from the crucible to the separate holding furnace when the conduit inlet is above the molten metal surface level.
