Title:
溶鉄製造方法および溶鉄製造装置
Document Type and Number:
Japanese Patent JP4214157
Kind Code:
B2
Abstract:
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.
