采用TSJ-3型微型烧结机研究了钒钛磁铁矿的液相基础性能，然后运用FactSage6.3软件中Equilib模型研究了温度、碱度和焙烧气氛对钒钛磁铁矿液相量（实际液相生成量与理论液相生成量的比值）和主要固相物质变化的影响。结果表明：烧结温度对液相量的影响非常大，随着烧结温度升高，液相量逐渐加大，但是料层高度不同其液相量也略有不同；碱度与液相量存在单调关系，即随着碱度升高，液相量增大；在氧化气氛逐渐增强的过程中，液相量增加但增速缓慢，过多地通入氧气，液相量不增反降。重点对比了不同碱度条件下软件模拟与实际烧结的结果，烧结试验与理论计算结果基本一致。

The base properties of vanadium-titanium magnetite sintered were studied by TSJ-3 Micro sintering machine and then the influences of alkalinity,temperature and calcination atmosphere on the vanadium-titanium magnetite phase formation and the solid phase material were also analyzed by FactSage6.3.The results indicated that the sintering tempera-ture has a great impact on the liquid content. With the increase of sintering temperature,the liquid phase was gradually in-creased,but material layer with different heights also leads to slightly different liquid content. Monotonicity was found be-tween alkalinity and liquid volume and the alkalinity increased with the increase of liquid phase. With the gradual increase of the oxidizing atmosphere,liquid content is increased,but the growth rate is slow. While with too much oxygen injected, liquid content will be reduced. By comparing the results of software simulation and actual sintering,the results of sintering test were basically consistent with the theoretical calculations.
