Title (EN) DISILIFICATION PROCESS OF MANGANESE ALLOYS
(FR) PROCEDE DE DESILICIATION D"ALLIAGES DE MANGANESE
Abstract: front page image
(EN)Disilification process of manganese alloys in a liquid phase. By injecting in the liquid alloys carbon dioxide, the effect of which may be completed by an additional neutral or oxidising gas, the silicon is oxidised into SiO2. The addition of lime stone or dolomite enhances the scorification of the silica. The silicon content may hence be lowered down to at least 0. 1%. Application for producing low carbon and low silicon ferromanganese.
(FR)Procede de desiliciation d"alliages de manganese, a l"etat liquide. En injectant dans l"alliage liquide du dioxyde de carbone, dont l"effet peut etre complete par un gaz additionnel neutre ou oxydant, on oxyde le silicium en SiO2. L"addition de chaux ou de dolomie favorise la scorification de la silice. La teneur en silicium peut ainsi etre abaissee au moins jusqu"a 0,1%. Application a l"obtention de ferromanganese a bas carbone et bas silicium.
