CHARGE FOR MELTING OF HIGH CARBON FERROMANGANESE

摘要

FIELD: metallurgy.;SUBSTANCE: invention refers to metallurgy, particularly to processing of manganese raw material by melting in ore reducing furnaces. Charge contains manganese raw material, carbon reducer and flux. As manganese raw material there is used mixture of concentrate of rare phosphorous manganese ore with ratio P/Mn=0.0052-0.042 and high grade manganese ore with ratio P/Mn≤0.0021 at following ratio of components, wt %: carbon reducer 12-18, flux 8-20, concentrate of rare phosphorous manganese ore with ratio P/Mn=0.0052-0.042 5-40, high grade manganese ore with ratio P/Mn≤0.0021- the rest. The invention facilitates processing low grade native manganese containing materials.;EFFECT: producing carbon ferromanganese with contents of phosphorus less 0,35% without using low-phosphorous manganese slag.;2 tbl
