CHARGE FOR PRODUCTION OF STEEL-MELTING FLUX Russian patent published in 2003 - IPC

FIELD: ferrous metallurgy, particularly, for production of flux for steel melting production. SUBSTANCE: charge components are mixed by their combined wet grinding, averaging in basins and subsequent roasting in rotating furnace. Charge includes material containing iron oxides and silicon, dolomite and hydrated wastes of dolomite roasting with the following amounts of components, wt. %: dolomite 20-70; hydrated wastes of dolomite roasting 20-70; the balance material containing iron oxides and silicon. EFFECT: reduced heat consumption for flux production and higher quality of flux due to averaging and increase of homogeneity of charge. 2 tbl, 1 ex
