Abstract

Apparatus for the continuous or semi-continuous casting of molten aluminium to form an ingot in the mould (8) of a casting machine, including a launder (4), a casting mould and feed means (2) which is coupled to the launder and extends into the casting mould. The feed means is connected to the underside of a tundish (3), and the tundish is provided with an inlet member (10) for admitting molten aluminium from the launder (4) into the tundish. The tundish is also provided with pressure-reducing means (5) for lowering the absolute gas pressure in the part of the tundish which is above the molten aluminium admitted into the tundish.
