https://doi.org/10.17073/0368-0797-2016-10-697-703

Abstract

The paper presents the research results of obtaining processes of metalized products by the method of solid-phase iron reduction from oxides of iron ores with the usage of coals of diff erent technological grades as a reducing agent. The authors give the results of hightemperature experiments on the kinetics study of the process of solidphase iron reduction from its oxides. According to the research results the coal optimum fl ows have been defi ned, as well as temperature and time parameters of the metallization process, which are necessary to obtain metalized materials with the specifi ed composition and the metallization degree.
