【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。更多还原

【Abstract】 A study on melting temperature of CaO-Al₂O₃-SiO₂-MgO-CaF₂ refining 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.更多还原
