ABSTRACT:
In the casting of ingots of aluminium alloys, containing a readily oxidizable component, in an open-ended mould, a space is enclosed over the molten metal surface adjacent the mould wall and is filled with an inert gas. The enclosure is maintained by a baffle which dips into the molten metal surface close to the baffle. The molten metal surface between the baffle and the mould wall is preferably covered by a layer of an oxide-dissolving flux, which cleanses the meniscus at the metal meniscus/mould wall interface.
