冶金炉渣硫化物容量指数与碱度的关系

Correlation between sulphide Capacity Index and Slag Basicity

采用１３００～１６００℃各种渣系的７６组平衡实验条件下和１２４组准平衡条件下工业实验数据，研究了本文所引入的硫化物容量指数与光学碱度、Ｂｅｌｌ比率、氧离子摩水分数的关系。结果表明，硫化物容量指数与炉渣各种表达方式的碱度之间有较好对应关系，但在准平衡的工业实验条件下，上述关系相对较离散。因此可认为，硫化物容量指数作为炉渣碱度的一种表示方法的观点似不能适用于所有条件。

the relationships between sulphide capacity index and optical basicity,oxygen ion mole fraction,Bells ratio were investigated based on extensive lab scale e-qilibrium and industry scale iso-eqilibrium experimental data in the range 1300～1600 ℃,Although the sulphide capacity index has good relations with slag basicitiesaccording to the data obtained in the lab scale eqilibrium experimental condition,thesimilar relations do not exist according to the data obtained in the industry scale iso-eqilibrium industry experimental condition,So it is concluded that the sulphlde capac-ity index,which was used as a mearsure of slag basicity,can not be empolyed for vir-tually all oxide slags of interest in the field of iron and steelmaking.
