Abstract

Il est mis à disposition un procédé de déphosphoration de métal fondu durant un procédé de raffinage, utilisant une composition de chaux sous la forme de particules compactées ayant un indice de Shatter test inférieur à 20 %, conduisant à un métal raffiné ayant une teneur réduite en composants phosphorés dans une mesure telle que le métal raffiné ayant une teneur réduite en phosphore présente une teneur en phosphore inférieure à 0,02 % en poids par rapport au poids total du métal raffiné ayant une teneur réduite en phosphore.
