【摘要】 在CaO-SiO₂-Al₂O₃系碱度为0.38～O.9的范围内,测定了添加剂Na₂O、CaF₂和B₂O₃对其熔化温度、粘度、密度和表面张力的影响,添加剂的加入量为2～15％.文章中简述了几个性质的测定方法,对粘度、表面张力等性质在固体保护渣中的作用进行了讨论.更多还原

【Abstract】 Measurements of the melting point, viscosity, density and surface tension, as affected by additions Na₂O, CaF₂ and B₂O₃ with composition of 2-15% were made for the CaO-SiO₂-Al₂O₃ systems with basicity over a range of 0.38-0.90. This paper describes the experimental method, and discusses the effect of these properties for solid protective slag on the quality of ingot.更多还原
