Process and equipment for producing iron carbide |
摘要 |
<p>The present invention provides method and apparatus capable of producing iron carbide having any quality, both quickly and economically. The method of producing iron carbide(Fe3C) comprises reducing and carburizing iron-containing raw materials for iron making such as iron ore and the like containing iron oxides (e.g. hematite) and iron hydroxides as main components. The hematite 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 hematite is further reduced and carburized by - a gas containing mainly hydrogen and methane in a second stage of the reaction process to provide iron carbide. <IMAGE></p> |
