METHOD OF DEOXIDIZING METAL

摘要

FIELD: nonferrous metallurgy. SUBSTANCE: method involves combined addition to ladle the carbon-containing and manganese oxide-containing materials followed by simultaneous addition of aluminium- and silicon-containing ferroalloys at ratio of manganese oxide-containing and carbon-containing materials and aluminium = 1:(0.05-0.50):(0.05-0.30), respectively. After outlet metal is blown with inert gas. EFFECT: decreased cost, improved manganese reduction degree.
