FIELD: ferrous metallurgy. SUBSTANCE: method of processing reactor raw material into cementite involves preliminarily heating this material in oxygen atmosphere. The thus obtained cementite is directly used to produce steel. Preliminary heating first leads to oxidizing raw material, then to desulfurization thereof if contains sulfur compounds, and, in the third place, to partially dehydrating raw material. Conditions for accomplishing mentioned processes are specified. EFFECT: facilitated processing of iron ore into steel. 24 cl, 8 dwg, 4 tbl
