为了研究含氟渣系成分变化对熔化温度的影响,根据五因素二次正交旋转回归法设计渣系配方,使用CQKJ-Ⅱ型高温矿渣熔化温度特性测定仪,采用半球法对CaF2-SiO2-Al2O3-CaO-MgO渣系的熔化温度进行测定;建立了五元含氟渣系熔化温度的回归模型,研究了各组元对熔化温度的影响。结果表明:当CaF2的含量(质量分数)在10%~70%时,各组元相互作用对精炼渣熔化温度有着显著影响。
In order to study the influence of the composition of the fluorine-containing slag system on the melting temperature, the slag system was designed according to the five-factor quadratic orthogonal rotation regression method. Using the CQKJ-Ⅱ high temperature slag melting temperature characterization instrument, Al2O3-CaO-MgO slag system. The regression model of the melting temperature of five-element fluorine-containing slag system was established and the influence of each component on the melting temperature was also studied. The results show that when the content of CaF2 (mass fraction) is 10% ~ 70%, the interaction of each component has a significant effect on the melting temperature of the refined slag.
