Abstract
L'invention se rapporte à la sidérurgie. Elle concerne un procédé de déphosphoration de fonte liquide, caractérisé en ce que l'on ajoute à celle-ci: a. Un agent de déphosphoration qui peut être la chaux, un laitier de convertisseur ou un mélange de ceux-ci ; et b. Un oxydant qui est tel que l'on obtienne un laitier contenant une quantité de CaO qui représente de 0,3 à 2,5 fois la somme des quantités de SiO2 et P2 O5 et qui a un T.Fe de 15 à 50 %. Utilisation pour la production d'aciers spéciaux.
