富铅渣与铅烧结块在还原反应中的差异研究

Study on Reduction Behaviours between Lead-rich Slag and Sinter

选用实验室制备的不同PbO含量的富铅渣与工业化生产的铅烧结块在竖管炉中用石墨坩埚进行还原反应对比试验。结果表明,烧结块和富铅渣主要以液相形式与碳反应。它们之间由于结构上的差异对还原反应的影响要小于成分的影响。

Lead-rich slags with different levels of PbO content have been prepared in laboratory. Reduction experiments have been conducted in a vertical tube furnace using graphite crucible to compare the different behaviours of lead-rich slag and sinter. It was found that both sinter and lead-rich slag react with carbon through liquid. The composition has greater influence on reduction rate than the structure.
