烧结钛精矿特性分析及钛渣冶炼工业试验研究

Characteristics analysis and industrial test of smelting titanium slag using sintered ilmenite concentrate

以攀枝花钛精矿为基础,通过成分、物相结构、熔化特性、理论测算等综合分析,表明烧结钛精矿与钛精矿原矿相比,有利于还原反应的快速进行,可缩短冶炼时间并降低冶炼电耗。进一步通过工业试验证明:采用烧结钛精矿冶炼过程反应速度快,吨渣电耗可以降低101.02 kWh/t,100 t料冶炼时间可以缩短0.6 h/炉。

On the basis of panzhihua ilmentie concentrate,through the comprehensive analysis of composition,phase structure,melting characteristics,theoretical calculation and so on,the results show that compared with the original ilmentie concentrate,the sintered ilmentie concentrate is beneficial to the rapid reduction reaction,which can shorten the smelting time and reduce the smelting power consumption.The further industrial test shows that the reaction speed of smelting with sintered ilmentie concentrate is fast,and the power consumption of titanium slag smelting can be reduced by 101.02 kWh/t,and the smelting time of 100 t material can be shortened by 0.6 h/furnace.
