METHOD OF MANUFACTURING IRON CARBIDE

摘要

An objective of the present invention is to provide a method for accelerating the generation of iron carbide, in which an iron-containing raw material is partially reduced in a first stage reaction process, and then the partially reduced iron-containing raw material is further reduced and carburized in a second stage reaction process to form the iron carbide. For attaining the object, the partial reduction of the first stage reaction process is performed in fluidized bed reactor 19, and the further reduction and the carburization of the second stage reaction process is performed in fluidized bed reactor 39. Carbon or carbon-containing gas is added to the reaction gas of the fluidized bed reactor 39.
