Abstract

SELON L'INVENTION, ON UTILISE EN COMBINAISON, AU COURS DE LA DESOXYDATION, DEUX FERRO-ALLIAGES CASIAL - DESIGNES DANS CE QUI SUIT PAR CASIAL ET CASIAL - SERVANT D'ADDITIFS DE DESOXYDATION, DE TELLE FACON QUE LA FRACTION DES DEUX AGENTS DE DESOXYDATION DANS LE MELANGE DE DESOXYDATION UTILISE SOIT DETERMINE EN FONCTION DE LA TENEUR EN C DE L'ACIER. LE RAPPORT EN POURCENTAGE EN POIDS CA:SI DANS LE FERRO-ALLIAGE CASIAL UTILISE DOIT SE SITUER ENTRE 1:18 ET 1:8 ET LA TENEUR EN AL ENTRE 1,0 ET 1,8OU LES FACTEURS X ET X PRENNENT LES VALEURS SUIVANTES: 70SI0,1, OU SI REPRESENTE LA TENEUR EN SI DES FERRO-ALLIAGES CASIAL ET CASIAL, EXPRIMEE EN POURCENTAGE EN POIDS.
