Definitions
- a material - for example an aluminum alloy - is transferred from the molten state to the solidified state by continuously feeding the alloyed or unalloyed melt into a short, water-cooled ring mold.
- the ring mold is closed off by a lowerable foot block on a casting table. By lowering the casting table, the cast ingot is produced with continuous replenishment of the mold space.
- the ring mold and the solidified cast product are cooled using water.
- molds with a ceramic structure on the mold (“hot top”) are also used, which reduce the temperature gradient in the solidifying melt, resulting in a more uniform structure Bar cross-section and a thinner edge shell with increased surface quality. Casting lengths are usually between 3 and 7 meters. (F. Ostermann “Aluminum Application Technology”, Springer, 2007, 2nd edition, p. 419f.).
- the melt of the aluminum alloy can optionally also contain one or more of the following elements in the proportions specified below: max. 0.2 wt.% Chromium max. 0.04 wt.% Zinc max. 0.02 wt .-% copper
- the weight ratio of iron to chromium to manganese (Fe:Cr:Mn) in the melt of the aluminum alloy is at least approximately 1:1:4.
- Figure 5 a schematic sketch to explain the production of the preliminary product according to the invention.

Abstract
L'invention concerne un procédé de fabrication d'un matériau de départ pour des éléments structuraux forgés en aluminium. Le procédé comprend la production d'un alliage d'aluminium contenant 0,7 à 1,8 % en poids de silicium, 0,5 à 1,4 % en poids de magnésium, 0,3 à 1,2 % en poids de manganèse, 0,005 à 0,5 % en poids de zirconium, 0,001 à 0,1 % en poids de titane et au plus 0,3 % en poids de fer au moyen d'une coulée continue par trempe directe. La masse fondue est guidée de telle sorte qu'elle n'entre pas en contact avec une surface solide lors de la trempe.
