摘　　要：　对电解铝厂实际电解质初晶温度的直接测定进行了研究,模拟出初晶温度与电解质组分以及初晶温度与分子比之间的关系模型,并利用计算机进行处理。通过测定电解质初晶温度及时给出各组分含量、分子比,研制出一种便携式初晶温度、分子比槽前分析仪。该仪器可用于电解铝厂电解质温度及分子比的现场分析。Liquidus temperature of actual samples of aluminum electrolyte was directly measured. Mathematic models about the relationships between liquidus temperature and their components and cryolite ratio were simulated and treated by computer. Cryolite ratio was obtained by the determination of liquidus temperature and a portable instrument, which can be used to determine the temperature and cryolite ratio, was made.

关 键 词：高温熔盐 初晶温度 分子比 分析仪
