The sintering characteristics of vanadium-titanium ore are summarized, and the main reasons for the poor strength of vanadium titanium sinter and the serious phenomenon of low temperature reduction pulverization are analyzed; and then the technical measures that can improve the sintering index of vanadium-titanium ore are introduced, such as increasing the binder phase of ferrite, controlling the fuel ratio, controlling the sintering temperature, adding limonite, strengthening briquetting, composite briquetting and spraying CaCl₂/B₂O₃ solution on the surface of the sinter; finally, the problems and solutions faced by vanadium-titanium ore strengthening sintering in iron and steel enterprises are prospected.
