Title:
PROCESS FOR MANUFACTURING REDUCED IRON/SLAG MIXTURE
Document Type and Number:
WIPO Patent Application WO/2013/073471
Kind Code:
A1
Abstract:
Concerning reduced iron and slag which are obtained in such a semi-molten state that each of the agglomerates is not completely molten, a technique for improving the separability between reduced iron and slag is provided. A process for manufacturing a reduced iron/slag mixture, successively including: a step of agglomerating a raw material mixture which comprises an iron oxide-containing substance and a carbon material and further contains a melting point regulator; and a step of heating the obtained agglomerates so as to melt each of the agglomerates partially, and thus reducing the iron oxide contained in the agglomerates.
