Abstract (en)
[origin: EP1749894A1] An iron ore, a carbonaceous material and a CaO-based auxiliary raw material are used as raw materials for sintering. The rawmaterials for sintering are charged into a sinteringmachine to form a raw material layer. A plurality of particles for manufacturing a reduced iron, which are produced by agglomerating at least the iron ore and the carbonaceous material, form a part of the raw material layer. The raw material layer is sintered and a part of the iron ore is reduced by sintering, thereby producing the semi-reduced sinter containing metallic Fe.
