摘    要：对转炉和含锌、 铅高炉尘泥的部分物性、 化学成分、 物相种类及分布尤其是含锌、铅物相分布的研究表明：两种尘泥的粒度均较小；转炉尘泥堆密度较大，铁含量较高；高炉尘泥的锌、 铅、 碳含量较高， 其中的大多数锌、铅氧化物均匀附着在硅酸盐和焦碳末粒子上。 这些特点有利于对两种尘泥采用造球-直接还原方法处理。

Abstract: The study of partial intrinsic properties, chemical composition and phase condition (especially the istribution of containing Zn, Pb phases) of the converter sludge and bearing-Zn-Pb blast furnace sludge showed that the particle size of the two kinds of sludges are all very small, the pile density of the converter sludge is much larger than that of blast furnace sludge; and the zinc, lead and carbon contents of blast furnace sludge are much larger than that of converter sludge, moreover most zinc oxide and lead oxide are attached on the particles of coke powder and silicates. These characteristics of sludges make it suitable to deal with them by pellet making and diretly reducingpellets.
