粉状五氧化二钒熔片过程中品位降低原因的分析

ANALYSIS ON THE REASON OF GRADE REDUCING IN THE MELTING PROCESS OF POWDERY VANADIUM PENTOXIDE

针对五氧化二钒生产中,五氧化二钒熔片过程造成片钒品位降低的现象,分析造成品位降低的因素为炉衬材质、烘干效果、脱氨效果,并通过试验进行了验证,对生产过程提出指导。

For the vanadium pentoxide grade reducing in melting process of powdery vanadium pentoxide,this paper analyzed the factors which affect the quality of vanadium are furance lining materials,dehydrating and the effects of removing ammonia. These are verified by the experiment. It will provide guidance for the production process.
