METHOD FOR PRODUCING METALLIC IRON

摘要

Provided is a method for producing metallic iron, which can be performed at a low temperature and which is a method for producing metallic iron by heating and reducing a starting mixture comprising a carbonaceous reducing agent and an iron oxide-containing substance in order to produce metallic iron wherein the carbonaceous reducing agent has a volatile content of 20 to 60 mass% and the gas derived from the carbonaceous reducing agent is a CO-CO2-H2 gas. The method for producing metallic iron comprises a step for producing solid Fe3C by heating the starting mixture in an atmosphere containing the CO-CO2-H2 gas; a step for melting the Fe3C; and a step for cementation of reduced iron via the molten Fe3C.
