Lub luag haujlwm ntawm Fervanadium yog dab tsi?

Dab tsi yog qhov ua haujlwm ntawmfervanadium?

Ferroalloys muaj li ntawm vanadium thiab hlau yog tsuas yog siv raws li alloy additives nyob rau hauv steelmaking, thiab high-vanadium ferrovanadium kuj yog siv raws li ib tug additive rau non-ferrous hlau alloys.

Feem ntau siv ferrovanadium muaj 40%, 60% thiab 80% vanadium. Lub ntsiab raw khoom rau zus tau tej cov ferrovanadium nyob rau hauv kuv lub teb chaws yog vanadium-titanium magnetite. Tom qab cov npua hlau uas muaj vanadium tau txais txiaj ntsig zoo thiab muaj txiaj ntsig zoo, nws tau ua kom zoo nyob rau hauv qhov cub tawg, thiab vanadium slag tau muab rho tawm hauv qhov cub atomizing lossis hloov tshuab tshuab.

Tom qab crushing, sodium ntsev (soda tshauv, anhydrous Glauber's ntsev) yog ntxiv rau vanadium slag rau sodium oxide roasting tig lub vanadium rau hauv soluble sodium metavanadate (NaVO3). Tom qab leaching thiab purification, ammonium sulfate yog ntxiv rau precipitate ammonium polyvanadate [(NH4) 2v6o16], thiab tom qab ntawd deamination thiab melting daim ntawv flake Vanadium pentoxide. Cov khoom xyaw uas xav tau yog v2o597 ~ 99%, P<0.05%, s<0.05%, na2o+k2o<1.5%.

Tsis tas li ntawd, Vanadium pentoxide tuaj yeem raug rho tawm ncaj qha los ntawm vanadium-muaj hlau mloog zoo lossis vanadium-muaj carbonaceous shale los ntawm kev kho tshuaj.
