Abstract

The slag foaming caused by Ti(C,N) is the main limitation of smelting vanadium–titanium magnetite by blast furnace. COREX, with unique pure oxygen injection that avoids the formation of Ti(C,N), has a huge potential advantage for the smelting of vanadium–titanium magnetite. In the present study, the detailed characterization was performed on the softening and melting behavior of V–Ti bearing burden under simulated COREX conditions. Results indicated that the added V–Ti bearing pellet (VTP) led to the increase of T10 and decreases of T40, TS and Td for mixed burden due to the generation of FeO·TiO2. Every 10 pct increase in VTP ratio reduced ΔT3 by 13.7 °C. Furthermore, the effect of VTP on burden dropping changed from inhibition (TiO2 → TiC) to promotion (\({({\mathrm{Si}}_{2}{\mathrm{O}}_{5}^{2-})}_{n}\to {({\mathrm{SiO}}_{3}^{2-})}_{n}\)) with increased VTP ratio, causing the burden dropping rate first to decrease from 70.0 to 13.5 and then increase to 96.6 pct, weakening the foaming of slag. When the VTP ratio reached 47.25 wt pct, the burden bed still had good gas permeability; its SD and PPeak caused by slag foaming were 8.06 kPa and 218.41 kPa·°C. The vanadium content in residual iron also exceeded 0.2 wt pct, the minimum requirement for extracting vanadium from molten iron.
