Abstract
La présente invention relève du domaine de la métallurgie et concerne, en particulier, des procédés de désoxydation de l'acier en fusion et d'alliages à l'aluminium. Elle concerne un procédé de traitement d'acier en fusion par l'aluminium. Selon ce procédé, l'aluminium est introduit dans la matière en fusion avec un alliage à base de fer, l'aluminium et l'alliage de fer se présentant sous forme d'un matériau composite dont la densité initiale est d'au moins 0,4 si on la compare à celle de l'acier en fusion, qui renferme Al, C, Si, Mn et Fe, et dont les ingrédients sont représentés comme suit en termes de pourcentages massiques: Al 25-50 C 0.05-0.90 Si 0.05-1.50 Mn 0.15-1.25, le reste étant constitué par du fer. Le matériau composite renferme de l'aluminium comme composante matricielle et d'autres ingrédients sous forme d'alliage de fer comme composante de renforcement. La dissolution de l'aluminium dans l'acier en fusion s'obtient en augmentant constamment la densité relative du matériau composite jusqu'à une valeur de 1,00-1,05. La présente invention permet d'améliorer l'efficacité du traitement de l'acier en fusion par assimilation d'aluminium et diminution des pertes d'aluminium.
