In order to minimize the incorrect disposal of dust generated in the basic oxygen furnace (BOF) converter and to generate a new application for this solid residue, a simple characterization route was proposed. The powder residue is used to produce self-reducing pellets and can be used in the blast furnace process. The chemical analysis of the dust was carried out using Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), and some elements as Fe, Si, P, Al and Ca were detected in high amount, as the iron which achieved about 65% concentration. Moreover, the X-ray diffraction analysis indicated that the iron was found in the phases, mainly, as magnetite (Fe3O4) and hematite (Fe2O3) while quartz (SiO2) and calcite (CaCO3) were the major impurities. The spectrometry dispersive energy (SDE) analysis confirmed the presence of such elements and the images obtained by SEM allowed visualizing the morphology of the particles. The average of particle size distribution of the dust was 0.053 mm which is suitable for self-agglomerates pellets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
