Empirical Study on Reduction Behavior and Metallurgical Properties of Vanadia–Titania Magnetite in Blast Furnace

The loss of permeability affects the reduction ferrous burden in cohesive zone a blast furnace (BF). Vanadia–titania magnetite (VTM) various chemical compositions have different metallurgical properties. and softening-melting-dripping properties kinds VTM were investigated. results showed that core sinter or pellet is indirectly reduced to wustite (Fe,Ti)Ox, periphery contains interlinked metallic iron CaSiO3 zone. Wustite (Fe,Ti)Ox are directly melting-dripping aggregate (Fe, V, Cr) present non-dripping causes valuable components. With increase TiO2 content, substrate phase molten slag changes from melilite titanaugite, mass dripping decreases gradually. In addition, index S increased melting widened, which indicates content negatively affected performance. proportional ratio. Considering adverse effect on properties, it recommended high smelted while mixed with ordinary ores an ratio structure.
