摘　　要：测试了ＳｒＯＳｉＯ２ＣａＯＡｌ２Ｏ３（５ ％ ）Ｎａ２Ｏ（１０％ ）ＣａＦ２（１０ ％ ） 六元渣系的熔点及粘度，绘制了等熔点曲线图及等粘度曲线图，得出了熔点及粘度与保护渣化学组成的数学关系式。通过对曲线图的分析，提出了含ＳｒＯThe melting point and viscosity of SrO SiO 2 CaO Al 2O 3(5%) Na 2O(10%) CaF 2(10%) flux system have been measured,and the curve charts of the melting point and viscosity are drawn.Moreover,the mathematical relations of properties with chemical composition are founded.The best range of chemical composition for mould flux containing SrO is presented via analyzing the curve charts.
