Abstract: Advantages of iron-rich pellet use in steelmaking in electric furnaces as compared to steelmaking scrap were reviewed. Decomposition of carbon and hydrocarbon oxides with carbon release was observed at the Kachkanar iron-rich pellet cooling in shaft furnaces, where they were reduced. The released carbon interacts with iron oxides and alloying elements. Derivatorgraphic research was carried out, which allowed establishing the temperature ranges of the iron oxide and alloying element reduction process as well as reaction mechanism depending on the carbon amount. To investigate the nature of alloying element distribution among the metal and slag phases a mineralogical analysis was carried out for carbon containing iron-rich Kachkanar pellets. The carried out research on alloying element (vanadium, titanium, manganese) distribution in Kachkanar iron-rich pellets after their post-reduction allowed process flow development for preparation of charge materials for steelmaking using spongy iron. A process was developed for vanadium and titanium containing alloying element production from iron-rich pellets containing carbon. © Published under licence by IOP Publishing Ltd.
