对碱度为１．５～２．５，ＦｅＯ％＜０．６～１．０的精炼渣进行了发泡性能的研究。实验在竖式电阻炉和２００ｋｇ中频感应炉内进行。分别测试了精炼渣碱度、精炼渣中助熔剂含量和发泡剂组成等因素对渣起泡率η＊、发泡持续时间τ和发泡指数Σ的影响
The basicity of 1.5 ~ 2.5, FeO% <0.6 ~ 1.0 refining slag foaming properties were studied. Experiments in the vertical resistance furnace and 200kg IF induction furnace. The effects of factors such as basicity of refining slag, content of flux in refining slag and composition of foaming agent on foaming rate η *, foaming duration τ and foaming index Σ were tested respectively
