multihearth roaster

The paper expounds detailedly the temperature control in the technology of roasting vanadium slag with sodium carbonate in eight-layered roast furnace in order to getting vanadates from the waste slag from experiments to industry produce in small scale until formal industry produce in large scale.

阐述了用八层焙烧炉进行钠化焙烧钒渣提钒焙烧工艺,先后在实验室、小规模试生产以及正式工业生产中,对焙烧工艺温度进行探索与确定。
