摘　　要：含钛高炉渣的熔化性温度是影响高炉炉渣冶金特性的关键因素。以工业生产含钛高炉渣为原料,进行正交试验研究,其结果表明：随着碱度的提高,熔化性温度上升,粘度也升高;MgO从6%增加到8%或8.5%时,熔化温度曲线温度转折点即熔化性温度从1 435℃降低到1 380℃;TiO2含量在16%~20%的条件下,渣中MgO在8%左右,Al2O3含量在9%~13%之间,TiO2对炉渣粘度与熔化性温度影响不大。Melting temperature is a key factor affecting metallurgical characteristics of titanium-bearing blast furnace slag.Result of an orthogonal test,which was conducted with industrially-produced titanium-bearing blast furnace slag as raw material,shows that,as alkalinity and melting temperature increases,and viscosity also increases;When MgO content rises from 6% to 8% or 8.5%,turning point of melting temperature curve goes down from 1 435 ℃ to 1 385 ℃;Under condition of TiO2 content of 16 ~ 20%,MgO content stays around 8%,Al2O3 content between 9% and 13%,and TiO2 has little effect on slag viscosity and melting temperature.
