In sintering process, vanadium titanium magnetite (VTM) is easy to generate perovskite and other ferrotitanium compounds, which are very unfavorable to the blast furnace smelting of VTM. Steelmaking process can concomitantly produce a great quantity oxidized scale, its main component is FeO. Calcium ferrite can be formed by oxidized scale with lime in air atmosphere and then added to the VTM in sintering process, XRD results indicated that perovskite is not generated at low temperature but only formed when temperature was raised to 1100 oC. Therefore, low-temperature sintering can be performed in the VTM sintering process doped with calcium ferrite. In order to compare the generation routes of perovskite, this paper also discussed the reaction mechanism of CaO-Fe2O3-TiO2 ternary system.
