The furnace slag generated from smelting of South African vanadium-titanium magnetite was taken in an experimental study by adopting direct reduction followed by melting, and then analyzed by XRD to investigate the effect of basicity on the metallurgical properties of the slag, as well as on the separation of iron from slag. Furthermore, the effect of basicity on the melting characteristics and viscosity of the slag were also explored. Results show that melting at 1 450 ℃ with the addition of carbon at an amount of 5%, the slag has its corresponding softening temperature, hemisphere temperature and flow temperature rising gradually with the increase in basicity. With the basicity ranging from 0.9 to 1.2, the melting temperature of slag increases rapidly, and the measured and calculated viscosity of slag presents a trend of an initial decrease followed by increase. When the basicity rising from 0.9 to 1.4, the diffraction peaks of pyroxene and feldspar in the slag climb to the high value and then start to fall, and the relative contents of perovskite and calcium-aluminum spinel gradually increase after an initial decrease. It is shown that the slag with basicity of 1.2 and viscosity of 0.130 Pa·s can present better performance.

以南非钒钛磁铁矿炉渣为研究对象,通过直接还原-熔分实验并结合XRD分析结果,研究了不同碱度下钒钛磁铁矿炉渣冶金性能及渣铁分离效果的影响,同时探究了碱度对炉渣熔化特性和黏度的影响规律。结果表明,熔分温度1 450 ℃、配碳量5%时,随着碱度提高,炉渣所对应的软化温度、半球温度与流动温度逐渐升高;炉渣碱度0.9~1.2时,炉渣熔化温度增长率较快,炉渣黏度实测值和计算值均呈先下降后上升的趋势;碱度从0.9上升到1.4的过程中,炉渣中辉石和黄长石的衍射峰强度先增强后减弱,钙钛矿和钙铝尖晶石相对含量呈先下降后逐渐上升的趋势。炉渣碱度1.2时,黏度为0.130 Pa·s,炉渣性能较好。

以南非钒钛磁铁矿炉渣为研究对象,通过直接还原-熔分实验并结合XRD分析结果,研究了不同碱度下钒钛磁铁矿炉渣冶金性能及渣铁分离效果的影响,同时探究了碱度对炉渣熔化特性和黏度的影响规律。结果表明,熔分温度1 450 ℃、配碳量5%时,随着碱度提高,炉渣所对应的软化温度、半球温度与流动温度逐渐升高;炉渣碱度0.9~1.2时,炉渣熔化温度增长率较快,炉渣黏度实测值和计算值均呈先下降后上升的趋势;碱度从0.9上升到1.4的过程中,炉渣中辉石和黄长石的衍射峰强度先增强后减弱,钙钛矿和钙铝尖晶石相对含量呈先下降后逐渐上升的趋势。炉渣碱度1.2时,黏度为0.130 Pa·s,炉渣性能较好。

The furnace slag generated from smelting of South African vanadium-titanium magnetite was taken in an experimental study by adopting direct reduction followed by melting, and then analyzed by XRD to investigate the effect of basicity on the metallurgical properties of the slag, as well as on the separation of iron from slag. Furthermore, the effect of basicity on the melting characteristics and viscosity of the slag were also explored. Results show that melting at 1 450 ℃ with the addition of carbon at an amount of 5%, the slag has its corresponding softening temperature, hemisphere temperature and flow temperature rising gradually with the increase in basicity. With the basicity ranging from 0.9 to 1.2, the melting temperature of slag increases rapidly, and the measured and calculated viscosity of slag presents a trend of an initial decrease followed by increase. When the basicity rising from 0.9 to 1.4, the diffraction peaks of pyroxene and feldspar in the slag climb to the high value and then start to fall, and the relative contents of perovskite and calcium-aluminum spinel gradually increase after an initial decrease. It is shown that the slag with basicity of 1.2 and viscosity of 0.130 Pa·s can present better performance.
