The abstract of the report is devoted to mathematical modeling of the kinetics of the process of metallic iron reduction from a single piece of iron ore reduced to the state of wustite, the main links of which are the melting of wustite and the reduction of metallic iron with the formation of carbon monoxide. The mathematical model developed by the author assumes the solution of the Stefan problem by the Duzinberre method for a piece of reduced ore (wustite). Its use allows studying the kinetics of the last stage of the process of stepwise reduction of iron with its carburization when using solid carbon as a reducing agent at the required sizes of iron ore pieces and various temperatures of the reduction process. The developed mathematical model can be used subsequently to develop a mathematical model of the complete process of obtaining iron from iron ore materials, consisting of successive stages of indirect (CO gas) and direct (solid carbon) reduction.
