摘 要: 對轉(zhuǎn)爐和含鋅、 鉛高爐塵泥的部分物性、 化學(xué)成分、 物相種類及分布尤其是含鋅、鉛物相分布的研究表明：兩種塵泥的粒度均較小；轉(zhuǎn)爐塵泥堆密度較大，鐵含量較高；高爐塵泥的鋅、 鉛、 碳含量較高， 其中的大多數(shù)鋅、鉛氧化物均勻附著在硅酸鹽和焦碳末粒子上。 這些特點(diǎn)有利于對兩種塵泥采用造球-直接還原方法處理。

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 reducing
pellets.
