A Study on Analysis of Sinter Microstructure and Phase Morphology

Sinter is a blast furnace input material obtained by heating to 900-1200 oC without full melting and adhering each other with superficial melting. It considered as multi-phase its sinter heterogeneous microstructure. In general, the main mineral phases are hematite, magnetite, silicoferrite of calcium aluminium (SFCA) silicates. By determining SFCA structure in material, sintering process will be made more stable important parameters affecting quality examined. from iron ore, steel industry products auxiliary materials. The scope this project determination amount formed bonding SiO2, CaO, Fe2O3, Al2O3 MgO compounds monitoring value parameter enterprise. samples having different characteristic features ready for X-ray diffraction (XRD) optical microscopy inspections polishing, etching freezing epoxy mineralogical researches. Before raw data analysis evaluated at Autoquan, they converted into Autoquan format then, read XRD device composition revealed analyses. Detailed view investigated so complete scanning electron microscope (SEM) analyses analyses; elemental valence conditions elements researched energy dispersive spectroscopy (EDS) method. Hematite, ferrite phase structures formations studied subject temperature during studies conducted on samples. Furthermore, it variations SFCA, SFCA-I SFCA-II within matrix parameters. ensured interpret results through rietveld
