通过试验着重分析探讨了五氧化二钒生产中熔化炉产量低的原因,是因为还原气氛太强,使已分解出的五氧化二钒又被还原成低价钒。提出了改变操作的方法,使生产每吨五氧化二钒节约煤气26.08km~3,熔化炉产量由10.7kg/m~2·h 提高到24kg/m~2·h,每年可增加经济效益219万元。 The reasons for the low output of the melting furnace in the production of vanadium pentoxide are analyzed emphatically through experiments because the reducing atmosphere is too strong so that the decomposed vanadium pentoxide is reduced to the low vanadium. Proposed to change the method of operation, so that the production per tonne of vanadium pentoxide gas savings of 26.08km ~ 3, melting furnace output from 10.7kg / m ~ 2 · h increased to 24kg / m ~ 2 · h, annual increase in economic benefits 219 Million.
