METHOD OF PRODUCING STEEL AND HYDRAULICALLY ACTIVE BINDERS FROM SLAGS Russian patent published in 1999 - IPC

Abstract RU 2127765 C1

FIELD: ferrous metallurgy. SUBSTANCE: method includes refining of pig iron with slag containing above 5% of iron oxides. Slag is reduced in the course of refining into clinker phase, separated from molten metal, discharged and cooled. Slag is used in the form of steel melting slag or Cu-converter slags after reaction with head bath, or oxidized slags from plants for incineration of wastes. EFFECT: provision of treatment of slag directly at steel plants and its conversion into hydraulically active binders. 14 cl, 5 tbl
