Abstract

La présente invention concerne un procédé de traitement de la fonte en fusion qui utilise un inoculant qui comporte : de 15 à 80 % en poids de Si ; soit du La de pureté allant de 80 à 100 % en poids, soit du Ce de pureté allant de 80 à 100 % en poids, en tant qu'élément des terres rares ; du Ca; et de l'Al ; le complément étant constitué de Fe et d'impuretés inévitables. Le procédé comprend un procédé d'inoculation de fonte en fusion, dans lequel l'inoculant est ajouté à la fonte en fusion de sorte que les quantités en éléments constitutifs ajoutés par rapport à la fonte en fusion sont de 0,001 à 0,009 % en poids de La ou de Ce, de 0,001 à 0,02 % en poids de Ca, et de 0,001 à 0,02 % en poids d'Al.
