Abstract
The results of a research of the fluxes usage effect on the physicochemical properties of sinter from mill scale are presented. The conducted studies have shown the expediency of introducing fluxes into the composition of the sintering charge. However, each flux in the form of quartzite or limestone (dolomitic) has its own advantage. When quartzite is used as a flux, X-ray phase analysis and microsection of the agglomerate confirm the presence of metallic iron. The introduction of limestone (dolomitic) into the sinter charge allows to produce a fluxed sinter. When using sinter for metal smelting, the fluxed sinter will allow limestone to be removed from the furnaces. The conclusion of which leads to the saving of a significant amount of heat spent on dissociation СаСО3 and MgСO3, thus saving fuel. Magnesio-ferrite formation (MgFe2O4), periclase (MgO), alumina in fluxed sinter is primarily due to the use of limestone (dolomitic). Magnesium contained in limestone dissociated with magnetite to form MgFe2O4 and MgO. To confirm the reliability of X-ray phase analysis, samples of the fluxed agglomerate were examined by scanning electron microscopy with the INCA Energy microanalysis system. Also, the average elemental composition of the sinter according to EDS analysis is shown in the figures and tables.
