全钒钛矿高炉冶炼合理炉料结构的探讨

在模拟高炉冶炼过程的条件下,研究了各种类型钒钛铁矿石(烧结矿、球团矿、块矿)的低温、高温还原和熔滴性能,特别是钒钛烧结矿碱度与高温冶金性能的关系及其对低、高温区域还原过程和钛还原行为的影响。在此基础上确认了全钒钛铁矿石高炉冶炼的合理炉料结构是高碱度烧结矿加酸性氧化球团矿。但在攀钢现有工艺和设备条件下,首要的是提高烧结矿的碱度。

Study on Reasonable Burden Structure of Smelting Vanadium Titaniferreus Magnetite in Blast Furnace

Under the condition of imitating the smelting process.the investigation has been carried out to the properties of melt dropping behaviours and reduction for several kinds of vanadium titaniferrous magnetites,such as sinter,pellet and lump ores;and especially the relation between the mineral constitute basicity of ores and its high temperature metallurgical quality is studied with its influence on the reduction process at the low and high temperature zones and the titanium reduction. So the reasonable burden mixture of smelting vanadium titaniferrous magnetites is high basicity sinter and acidity pellet. However,with the existing conditions of the steel plant.it is essential to improve the basicity of the sinter.
