Document Type and Number:

WIPO Patent Application WO/2005/111248

Kind Code:

A1

Abstract:

An iron ore, a carbon material and a CaO based auxiliary material are used as materials for sintering, and the materials for sintering are charged into a sintering apparatus and constitute a material layer, wherein a plurality of particles for producing reduced iron prepared by forming at least the iron ore and the carbon material account for a part of the above material layer. The above material layer is sintered and a part of the iron ore is reduced, to thereby produce a semi-reduced sintered ore which contains metallic Fe.
