Abstract (en)
Molten magnesium alloy is continuously or semi-continuously supplied to a casting die or mould (13) at the feed point (12) thereof through a closed conduit (5) through which molten alloy is passed without contact with the atmosphere. A first section (6) of the conduit (5) takes the form of a helix immersed in a fluidized bed (8) heating the alloy to a grain refining temperature. A subsequent second section (7) of the conduit (5) in the form of a helix is immersed in a second fluidized bed (9) in which the alloy is cooled to a controlled casting temperature. The conduit (5) supplies the alloy at the level (14) of the inlet (12) to the casting die or mould (13) by control of the pressure of the molten alloy in the conduit (5).
