以CaO-SiO2-MgO-Al2O3-TiO2系含钛高炉渣为研究对象，分别研究TiO2和MgO质量分数对含钛高炉渣结晶行为的影响。结果表明：在1 500 ℃时没有晶体析出，渣系主要以玻璃相存在；当温度为1 460、1 420和1 380 ℃时，析出的晶体主要为镁铝尖晶石相和（或）钙钛矿相；当TiO2质量分数由10%增加至25%时，镁铝尖晶石相的析出温度明显降低，钙钛矿相的析出温度升高；当MgO质量分数由10%增加至14%时，镁铝尖晶石相的析出温度明显提高，钙钛矿相的析出温度没有明显改变，但钙钛矿相的析出比例增加。
This paper takes CaO-SiO2-MgO-Al2O3-TiO2 in titanium-bearing blast furnace slag as the research objects， and studies the effect of TiO2 and MgO mass fractions on the crystallization behavior of titanium-bearing blast furnace slag. The results show that the slag mainly exists as a glass phase and no crystals precipitate at 1 500 ℃. When the temperature is 1 460， 1 420， and 1 380 ℃， the precipitated crystals are mainly the Mg-Al spinel phase and/or perovskite phase. When the mass fraction of TiO2 increases from 10% to 25%， the precipitation temperature of the Mg-Al spinel phase decreases significantly， and the precipitation temperature of the perovskite phase increases. When the mass fraction of MgO increases from 10% to 14%， the precipitation temperature of the Mg-Al spinel phase remarkably increases， and the precipitation temperature of the perovskite phase does not change， but the precipitation proportions of the perovskite phase increases.
