Abstract

PROCEDE POUR ACCROITRE LA LONGEVITE DU GARNISSAGE A TENEUR EN MAGNESITE DE FOURS A ARC ELECTRIQUE DANS LESQUELS DES CHARGES SOLIDES SONT MISES EN FUSION PUIS AFFINEES SOUS SCORIE A TENEUR EN CHAUX ET EN OXYDE DE MAGNESIUM. SELON L'INVENTION ON AJOUTE A LA CHARGE DU FOUR DE LA CHAUX DE DOLOMITE, EN QUANTITE POUVANT ATTEINDRE 25 A 30KG PAR TONNE D'ACIER. CETTE CHAUX PEUT ETRE PULVERULENTE ET REPANDUE SUR LE SCORIE A L'AIDE D'UNE LANCE MOBILE.
