<p>A process for producing particulate iron metal through the reducing fusion of a feed material mixture comprising an iron oxide-containing substance, e.g., iron ore, and a carbonaceous reducing agent, e.g., a carbon-containing material, in a moving-bed type heating/reducing oven, wherein especially the content of the sulfur which has come into the particulate iron metal from the carbon-containing material such as coal is minimized. Thus, high-quality particulate iron metal reduced in sulfur content is obtained. The amounts of CaO-, MgO-, and SiO2-containing substances contained in the feed material mixture are regulated so that the slug-forming ingredients have a basicity (CaO+MgO)/SiO2, as determined from the contents of CaO, MgO, and SiO2 in the feed material mixture, of 1.3 to 2.3 and further have an MgO content (MgO) of 5 to 13 wt.%.</p> |
