摘　　要：测试了ＢａＯ－ＳｉＯ２－ＣａＯ—Ａｌ２Ｏ３（５％）—Ｎａ２Ｏ（１０％）ＣａＦ２（１０％）六元渣系的熔点及粘度。绘出了熔点曲线图及粘度曲线田。求出了性质与化学组成的数学关系式。在此基础上，提出了含ＢａＯ保护渣恰当的组成范围。The testing of the melting-points and viscosity of BaO-SiO2-CaO-Al2O3(5%)-Na2O(10%)-CaF2(1 0%)six-part slag system is completed. Then the curve charts of the melting-points and viscosity are drawn. Moreover, the mathematical relations between properties andchemical compostion are found out.As a result,the proper range of chemical composition for BaO-contained mould fluxes is therefore presented.
