Abstract

Abstract: A study on melting temperature of CaO-Al₂O₃ -SiO₂-MgO-CaF₂refining slag has been carried out by using orthogonal experimental method. With variance analysis and significance criterion it is obtained that the optimum ingredient of the pentatomic refining slag is 25% Al₂O₃, 12% CaF₂, 7% MgO and R2 ( CaO/SiO₂) =2.5. And the regression analysis is carried out by using SPSS software to get the math relationship equation between ingredient with high reliability and melting temperature of refining slag: T_m = 1 451.3 - 6. 25CaF₂ - 7. 36R₂.

摘要： 利用正交实验的方法对CaO-Al₂O₃-SiO₂-MgO-CaF₂精炼渣的熔点进行了研究。经过方差分析和显著性检验,得出该五元精炼渣系的最佳组成为:25%Al₂O₃、12%CaF₂、7%MgO、R2(CaO/SiO₂)=2.5。并用SPSS软件回归出了可信度高的组分与精炼渣熔化温度之间的数学关系式:T_m=1 451.3-6.25CaF₂-7.36R₂。
