| 摘要 |
The disclosure relates to improvements of technology for producing metallic iron by thermally reducing an iron source such as iron ore with a carbonaceous reductant such as coke by including efficiently reducing iron oxides into metallic iron at a lower operation temperature while conducting carburization, and efficiently separating the generated metallic iron from slag-forming components such as gangue components contained in raw material ore whereby metallic iron with controlled carbon concentrations can be produced in high yield.
