Abstract Miniature sintering device was applied to make systematic study on a kind of imported vanadium and titanium magnetite with high chrome as well as several kinds of iron ores for sintering in production field, in order to provide the theory basis and technical parameters for sintering and ore proportioning of high chrome vanadium and titanium magnetite. The experiment results show that there is a great range of disparities between different iron ores. The imported vanadium and titanium magnetite with high chrome has a high assimilation temperature (1335℃), a bad liquid phase liquidity (liquidity index 1.95), weak strength of binding phase (1445N of the compressive strength), and bad crystal strength (365N of the compressive strength). However, the mixture of domestic iron ore and the imported magnetite with high chrome content used at the production spot has moderate assimilation temperature (1291℃), good liquid phase liquidity (liquidity index 4.20), strong strength of binding phase (2010N of the compressive strength), and comparatively good crystal strength (622N of the compressive strength). From the aspect of the above basic sintering characteristics, this kind of imported vanadium and titanium magnetite with high chrome content should be used in proportion with the mixed domestic iron fine ore during the practical sintering production as much as possible, on basis of the current raw material conditions.
