Method for producing iron carbide |
摘要 |
An apparatus and method of producing iron carbide of predetermined quality is disclosed. The method of producing iron carbide (Fe3C) comprises reducing and carburizing an iron-containing raw material containing iron oxides (e.g., hematite) or iron hydroxides as main components, wherein the raw material is partially reduced to a reduction ratio of 50 to 65% by a gas containing mainly hydrogen in a first stage of the reaction process, then the partially reduced raw material is further reduced and carburized with a gas containing mainly hydrogen and methane in a second stage of the reaction process to provide iron carbide.
