Abstract

La présente invention concerne un procédé de décarburation des ferro-manganèses à forte teneur en carbone, dits << carburés >>, afin d'obtenir des ferro-manganèses à plus faible teneur en carbone, dits << affinés >>, par soufflage de divers fluides à travers des tuyères immergées protégées. Ce procédé qui utilise le soufflage, au-dessous du niveau du bain métallique, d'un gaz oxydant, de vapeur d'eau et/ou d'un gaz inerte, au moyen de tuyères immergées, protégées contre l'usure par introduction d'un fluide périphérique refroidissant, est caractérisé par deux phases principales successives, qui sont fonctions de la teneur en carbone du bain et pendant lesquelles interviennent des proportions définies des divers fluides en présence, de manière à assurer une régulation thermique prédéterminée et limitant la volatilisation du manganèse. Ce procédé s'applique spécialement bien à l'affinage des ferro-manganèses.
