Study on Sintering Characteristics of Ultra-Poor Vanadium-Titanium Magnetite

Artificial rich ore for blast furnace use can be produced by sintering ultra-poor vanadium-titanium magnetite (PVTM) with a high-grade iron concentrate. Here, acid (R = 0.33, 0.50), self-fluxing 1.10), and high-basicity 2.60) PVTM sinters were in sinter pot. Their performances determined using the comprehensive index. The microstructures of observed metallographic microscope scanning electron microscopy equipped an energy dispersion spectrum (SEM-EDS). results suggest that had low flame front speed, productivity, uneven size distribution, poor softening properties. It did have high tumble index (TI) low-temperature reduction disintegration (RDI). worst performance (TI, RDI, reducibility (RI)), while highest reasonable excellent properties, satisfactory TI RDI values. main consolidation form was crystal stock, bonding phase silicate, silico-ferrite calcium aluminum (SFCA). values (from to low) 2.60), natural 0.33), 1.10) sinters. When production capacity pellet shortage, 0.50) could surplus from plant. This replaced part burden structural model smelting vanadium so titanium adopt ‘high-basicity + V-Ti sinter’.
