Dab tsi yog kev siv ntawmfervanadium?
FeV yog cov hlau tsis tshua muaj nrog ntau yam kev siv. Nws tau nkag siab tias vanadium feem ntau yog siv hauv cov hlau los hloov cov khoom ntawm cov hlau. Tib lub sijhawm, ferrovanadium tau raug coj mus muag hauv Tebchaws Meskas, Canada, Europe, Nyiv, Australia thiab lwm lub tebchaws. Nws cov kev lag luam siv yog tsuas yog siv rau cua zog lub zog cia, photovoltaic zog cia thiab daim phiaj peak tswj. FeV80 yog dav siv nyob rau hauv ib txwm teb xws li tshuaj dawb, pleev xim, thiab papermaking, thiab cov txheej txheem titanium yog siv nyob rau hauv aerospace, tub rog thiab lwm yam teb. Cov kws tshaj lij kwv yees tias nrog kev txhim kho sai ntawm lub zog tshiab thiab kev txhim kho cov kev xav tau ntawm cov hlau, cov ntawv thov yav tom ntej ntawm ob cov ntaub ntawv no yuav dav heev.
Iron Vanadium yog lub npe hu ua "modern industrial monosodium glutamate" thiab yog dav siv hauv steel, tshuaj lom neeg kev lag luam, aerospace thiab lwm yam kev lag luam. 85% ntawm nws yog siv hauv kev lag luam steel. Ntxiv Vanadium Hlau rau hlau tuaj yeem txhim kho cov hlau hnav tsis kam, lub zog, hardness, ductility thiab lwm yam khoom. Ntxiv 0.1% Industrial Ferrovanadium tuaj yeem ua kom lub zog ntawm cov hlau los ntawm 10%-20%, txo qhov hnyav ntawm cov qauv los ntawm 15%-25%, thiab txo tus nqi los ntawm 8%{{ 8 }}%.
Txawm hais tias ferrovanadium muaj ntau yam zoo, nws yooj yim ua rau ib puag ncig muaj kuab paug thaum lub sijhawm tsim khoom. Muaj ntau cov pa phem thiab cov pa phem thiab cov dej khib nyiab tawm thaum lub sij hawm FeV alloy refining txheej txheem. Cov pa tso pa muaj hydrogen chloride, sulfur dioxide thiab sulfuric acid, uas muaj kev cuam tshuam loj heev rau cov nroj tsuag thiab qoob loo; cov dej khib nyiab muaj hexavalent chromium, cadmium, arsenic thiab lwm yam kuab paug, uas muaj teeb meem rau tib neeg thiab tsiaj txhu thiab tuaj yeem tsim cov kua qaub los nag. Tam sim no, kev tsim khoom tau hloov mus rau cov teb chaws tsis muaj kev tsim kho thiab cheeb tsam.
Tsis tas li ntawd, Vanadium Iron Alloy tseem hu ua "kev sib tw hlau". Ferrovanadium thiab nws cov alloys muaj cov khoom zoo heev xws li kev tiv thaiv corrosion, siab zog, siab thiab kub tsis tshua muaj zog, tsis muaj hlau nplaum, zoo tib neeg adaptability, zoo nco thiab superconductivity. Vim nws lub teeb yuag thiab lub zog siab, nws tau siv dav hauv aerospace thiab lwm qhov chaw. Nyob rau hauv xyoo tas los no, nws daim ntawv thov tau maj mam nthuav mus rau pej xeem kev lag luam xws li nkoj tsim, petrochemical khoom, offshore platforms, khoom siv fais fab, kev kho mob, thiab cov khoom siv.
Muaj ob txoj hauv kev rau rho tawm hlau vanadium los ntawm magnetite: txoj kev tua hluav taws yog rho tawm cov hlau vanadium ncaj qha los ntawm kev mloog zoo lossis vanadium slag, thiab txoj kev ntub dej yog rho tawm hlau vanadium ncaj qha los ntawm kev mloog zoo. Tam sim no, kuv lub teb chaws tsuas yog siv txoj hauv kev ntawm kev rho tawm ncaj qha ntawm fervanadium. Pyrogenic vanadium extraction txheej txheem: Lub ore hnav khaub ncaws khoom vanadium concentrate yog smelted ncaj qha rau hauv lub moj tej tawg cub tawg los yog hluav taws xob rauv, thiaj li hais tias feem ntau ntawm cov vanadium nyob rau hauv lub ore nkag mus rau molten hlau, thiab ces cov dej uas muaj vanadium raug xa mus rau lub converter rau oxygen tshuab. kom ntxiv dag zog rau vanadium hauv slag. Ua vanadium slag. Vanadium peroxide yog tau los ntawm vanadium slag los ntawm roasting, leaching thiab pom. Ib qho txiaj ntsig zoo ntawm txoj kev no yog qhov siab rov qab ntawm vanadium.
Kuv vam tias cov lus qhia ntxaws saum toj no tuaj yeem ua rau txhua tus nkag siab zoo dua ntawm Iron Vanadium Alloy. Feem ntau hais lus, cov khoom siv raw khoom no tsis tsuas yog muaj ntau yam kev siv, tab sis kuj muaj tus nqi lag luam siab. Txawm li cas los xij, vim qhov nyuaj ntawm cov txheej txheem refining, nws cov nqi hauv kev ua lag luam kuj tseem siab.
