| 摘 要： | 采用相对易磨性的方法比较了水淬高炉渣、滚筒转炉渣和风碎转炉渣的粉磨能耗。采用粒度分布和分形方法研究了炉渣微粉的特性。研究结果表明：水淬高炉渣易磨性最好，而滚筒转炉渣易磨性最差。水淬高炉渣微粉整体粒径分布均匀，不同粒度范围内微粉特性差异较小。而转炉渣中存在明显的难磨相，不同粒度范围内的分形分维数有明显差异。当炉渣微粉磨至很细时，单位质量滚筒转炉渣和风碎转炉渣的能耗分别约是水淬高炉渣的3.19和2.17倍。转炉渣中存在的FeO和金属铁导致其相对水淬高炉渣更难磨。滚筒转炉渣中的大量MgO·2FeO相导致其比风碎转炉渣更难磨。

| Abstract: | The specific energy consumption of grinding for such three different slag powders as water-quenching blast furnace(W-BF) slag,water-spraying basic oxygen furnace(W-BOF) slag and air-quenching basic oxygen furnace(A-BOF) slag,were compared using relative grindability method,and the characteristics of slag powder was investigated by using particle size distribution and fractal analysis.The results show that W-BF slag has better grindability than BOF slag.As for W-BF slag,its particle size distribution is regu... |
