Abstract
Provided is a method for managing an operation of a producing process for obtaining an iron carbide product having a goal composition in a two-stages reaction process. A first-stage reaction process for partially reducing an iron-containing material for iron making is carried out, and a second-stage reaction process for performing further reduction and carburization is then carried out. A solid sample is taken at an outlet of a reactor for the first-stage reaction process to measure a reduction ratio of the solid sample. By regulating a parameter capable of changing a reduction ratio of the first-stage reaction process, an IC ratio obtained after the second-stage reaction process can be adjusted.
