摘要: 使用RTW-10型熔体物性综合测定仪,测定CaO-SiO2-MgO-Al2O3-TiO2渣系粘度随温度的变化,并计算其熔化性温度,研究渣系高温冶金性能. 结果表明,渣中TiO2含量由1.0%升高至2.2%时,炉渣的熔化性温度和粘度均降低;随渣中Al2O3含量的提高,炉渣的熔化性温度上升,炉渣粘度增大;在高温区,炉渣粘度小于0.7 Pa×s,炉渣仍具有良好的流动性. MgO含量由8.5%升高至10.5%时,熔化性温度逐渐降低,炉渣粘度变化较小. 对于工业生产中炉渣TiO2含量较低的高炉,可考虑增加含钛原料的使用,以进行护炉操作.

Abstract: RTW-10 integrated instrument for measurement of melt properties was used to measure the variation of viscosity of CaO-SiO2-MgO-Al2O3-TiO2 slag system with temperature, its melting temperature calculated, and the high-temperature metallurgical properties of the slag were studied. The results showed that when TiO2 content in the slag increased from 1.0% to 2.2%, both the melting temperature and viscosity decreased. With increasing of the Al2O3 content, the melting temperature and viscosity of the slag increased, but in high temperature range, the slag viscosity was less than 0.7 Pa·s, it still had good fluidity. When the MgO content increased from 8.5% to 10.5%, the slag melting temperature decreased, but the slag viscosity slightly changed. For industrial production with lower TiO2 content blast furnace slag, increasing the use of titanium-containing raw material could provide the protection of furnace operation.

Key words: blast furnace, titanium slag, metallurgical property, melting temperature, viscosity
