发明名称 METHOD OF PRODUCING PIG IRON WITH USE OF BLAST-FURNACE PROCESS AT METALLURGICAL ENTERPRISE
摘要 FIELD: metallurgical processes, more specifically, technology of pig iron production. SUBSTANCE: method includes charging into blast furnace of burden materials which consist of flux sinter, pellets, solid fuel and metal additions, blowing into furnace of atmospheric or combined blast and also supply to furnace of rate-earth metals in amount of 0.001-0.7 wt.% and strontium in amount of 0.01-1.0 wt.% which were particularly charged simultaneously with introduction of flux sinter and/or in its composition and partially in composition of burden materials in the form of metal- and oxides-containing compositions. EFFECT: higher quality of pig iron due to raised intensity and depth of desulfurization at stage of blast-furnace process. 18 cl, 1 tbl
