Abstract
Apparatus for the continuous or semi-continuous casting of molten aluminium to form an ingot in the mould (8) of a casting machine, comprising a launder (4), a casting mould and feed means (2) which are coupled to the launder and extend into the casting mould, and wherein the feed means are connected to the underside of a tundish (3), said tundish is provided with an inlet member (10) for admitting molten aluminium from the launder (4) into the tundish and further with pressure-reducing means (5) for lowering the absolute gas pressure in that part of the tundish which is above the molten aluminium admitted into the tundish.
Claims14
Apparatus for the continuous or semi-continuous casting of molten aluminium to form an ingot in the mould of a casting machine, the apparatus comprising a launder, a casting mould and feed means which are coupled to the launder and extend into the casting mould, characterized in that the feed means are connected to the underside of a tundish, said tundish is provided with an inlet member for admitting molten aluminium from the launder into the tundish and further with pressure-reducing means for lowering the absolute gas pressure in that part of the tundish which is above the molten aluminium admitted into the tundish.
Method for the continuous or semi-continuous casting of molten aluminium to form an ingot in the mould of a casting machine, comprising the steps of casting molten aluminium via a launder and by using feed means which are coupled to said launder and extend into a casting mould, characterized in that the absolute gas pressure is being lowered, by means of pressure-reducing means, above the molten aluminium admitted into a tundish, said tundish being coupled at its underside to the feed means and is further provided with an inlet member for admitting molten aluminium from launder into the tundish.
