CHARGE FOR CARBONACEOUS FERROMANGANESE MELTING

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention concerns metallurgy field. Particularly it concerns manufacturing of ferromanganese with carbon content 5.0- 7.0 mass%. Charge contains, mass %: manganese concentrate of chemical enrichment 50.0-54.0; iron chips 1.0-3.0; coke 10.0-12.0; silicomanganese waste slug 8.0-12.0; silicon 25.0-27.0. Silicon ratio to manganese concentrates of chemical enrichment 1:2. ^ EFFECT: reducing of manganese losses at that useful manganese is 97-98%. ^ 1 tbl, 2 cl
