Abstract
FIELD: ferrous metallurgy; methods for production of low-phosphorus low-iron charge slag for smelting of ferroalloys based on vanadium, chromium and manganese. SUBSTANCE: introduced additionally into melted charge is material containing oxide of same metal at mass ratio of charge metal and oxide components of (0.15-0.4):1. When metal component of charge is used in form of crumbs of ferromanganese (Mn 65%, P 0.35%, C 8%) and oxide component in form of slime of blast furnace production of ferromanganese (FeO 6.5%; Mn 21.7%; PO0.35%, C 11.8) charge slag is obtained which contains Mn 45.9-52.3%, FeO 0.7-0.85%, PO0.062-0.075%. This slag is useful in production of manganese-containing alloys satisfying the requirements of the ferroalloys standards in force. EFFECT: increased yield of charge slag enriched with oxide of leading element and its higher degree of enrichment.
