中文摘要: 以攀枝花高钛型高炉渣为主要原料,采用正交试验设计法研究了高炉渣主要组分(CaO/SiO2、TiO2、Al2O3、MgO)对其半球点温度、流动温度及黏度的影响。结果表明,高炉渣主要组分对其半球点温度影响的大小顺序为:R2>TiO2>MgO>Al2O3;对流动温度的影响顺序为:Al2O3>R2>MgO>TiO2;对黏度的影响顺序为:R2>Al2O3>TiO2>MgO;随着碱度增加,熔化温度及黏度呈先升高后降低的规律;随着TiO2含量的增加,熔化温度呈先升高后略有降低的趋势,黏度呈先降低后增加的趋势;随着Al2O3含量增加,半球点温度呈先减小后增大的趋势,流动温度大致呈逐渐增大的趋势,黏度呈先降低后升高再降低的变化趋势;随着MgO含量的增加,熔化温度有一定的降低,黏度呈先升高后降低的趋势。
Abstract:With titanium-bearing blast furnace slag in Panzhihua as raw materials, the effects of main components of blast furnace slag( CaO/SiO2, TiO2, Al2O3, MgO ) on melting characteristics and viscosity properties was studied through orthogonal design in this paper. The results showed that the order of various factors affected on slag’s hemisphere point temperature is: R2>TiO2>MgO>Al2O3, and the order on flowing temperature is: Al2O3>R2>MgO>TiO2, and the order on viscosity is: R2>Al2O3>TiO2>MgO. The melting temperature increases with the increasing of alkalinity and TiO2 content and then decrease, however, the temperature continuously decreases with the increasing of MgO content in the experiment range. The viscosity increases with the increasing of alkalinity and MgO content and then decrease. With the increasing of TiO2 content and MgO content, the viscosity decreases firstly, then increases. With the increasing of Al2O3 content, the slag’s hemisphere point temperature decreases at first then increases, and the flowing temperature decreases basically.
