中文摘要: 对攀西钒钛磁铁精矿球团电炉冶炼进行研究,通过还原剂作用和优化的熔融还原电炉参数,可实现钒钛磁铁精矿球团冶炼过程中铁和钒钛的分离回收,其中钒被还原后富集到生铁中,而钛富集在电炉冶炼渣中。当渣型碱度(CaO/SiO2)为1.1时,还原球团的金属化率为70%,在1 500 ℃熔融还原10 min后,生铁中铁品位为97.96%,铁回收率可达98.81%,生铁中含钒0.36%,钒回收率可达62.42%,试验过程中炉渣流动性好。
Abstract:Electric furnace smelting technology was adopted to treat vanadium-titanium magnetite concentrate in Panzhihua. The results show that separation and distribution of iron and non-ferrous elements can be controlled with suitable reducing agent, appropriate metallization rate of pre-reduction pellets and optimized electric furnace smelting temperature and time. Most of vanadium is collected in pig iron, while titanium is gathered in furnace slag. Pig iron is obtained with iron grade of 97.96% and iron recovery of 98.81%, vanadium content of 0.36% and vanadium recovery of 62.42% under the conditions including alkalinity (CaO/SiO2) of 1.1, metallization rate of 70%, smelting temperature of 1 500 ℃ and smelting time of 10 min. Furnace slag exhibits good fluidity in smelting process.
