Khoom Description
Ferro Vanadium: koj puas xav tau ntau tus thwjtim?yog ib qho ferroalloy tsim los ntawm vanadium thiab hlau. Nws yog tsuas yog siv los ua alloy additive hauv steelmaking. High-vanadium ferrovanadium kuj yog siv los ua ib qho ntxiv rau cov hlau tsis muaj hlau.
Cov hlau thiab titanium master alloy (hlau-vanadium binary alloy) tau los ntawm kev txo qis muaj vanadium cov ntsiab lus tsis tsawg dua 35.0% (qhov hnyav) thiab tsis ntau tshaj 85.0% (qhov hnyav) .
Raws li ib tug tswv cuab ntawm vanadium tsev neeg lub caij nyob rau hauv lub sij hawm ntawm lub ntsiab lus, vanadium muaj ib tug melting point ntawm 1887 degrees thiab ib tug boiling point ntawm 3337 degrees. Ntshiab vanadium yog ci dawb, tawv hauv kev ntxhib los mos, thiab muaj lub cev-chaw rau peb-dimensional qauv.
Kwv yees li 80% ntawm vanadium yog siv ua ke nrog hlau ua ib qho khoom siv hlau hauv hlau. Cov hlau uas muaj vanadium muaj zog heev thiab muaj zog, tab sis feem ntau muaj tsawg dua 1% vanadium.
Cov khoom parameter
Feem ntau siv ferrovanadium muaj 40%, 60% thiab 80% vanadium. Lub ntsiab raw khoom rau Tuam Tshoj ferrovanadium ntau lawm yog vanadium-titanium magnetite. Tom qab tau txais txiaj ntsig thiab kev nplua nuj, vanadium-muaj cov npua hlau yog smelted los ntawm lub qhov cub tawg, thiab vanadium slag raug rho tawm thaum lub sij hawm atomizing rauv los yog converter tshuab. Tom qab lub vanadium slag yog crushed, sodium ntsev (soda tshauv, rooj ntsev los yog anhydrous Glauber's ntsev) yog ntxiv rau sodium oxidation roasting tig lub vanadium rau soluble sodium metavanadate (NaVO3). Tom qab leaching thiab purification, ammonium sulfate yog ntxiv rau precipitate polyvanadate. Ammonium [(NH4) 2V6O16] ces yaj los ntawm deamination thiab muab pov rau hauv flake-zoo li vanadium pentoxide. Cov khoom xyaw uas xav tau yog V2O597 ~ 99%, P<0.05%, S<0.05%, Na2O+K2O<1.5%. In addition, vanadium pentoxide is also extracted directly from vanadium-containing iron concentrate or vanadium-containing carbonaceous shale through chemical treatment.
siv cov khoom
Ferrovanadium feem ntau yog siv los ua cov khoom siv hlau alloy hauv steelmaking. Tom qab ntxiv ferrovanadium rau steel, hardness, lub zog, hnav tsis kam thiab ductility ntawm cov hlau tuaj yeem txhim kho tau zoo, thiab kev ua haujlwm ntawm cov hlau tuaj yeem txhim kho. Ferrovanadium feem ntau yog siv rau hauv kev tsim cov pa roj carbon steel, low-alloy zog steel, high-alloy steel, cuab yeej steel thiab cam khwb cia hlau.
Cov hlau vanadium feem ntau yog siv rau hauv cov hlau tsis muaj hlau los tsim cov vanadium-titanium alloys, xws li Ti-6Al-4V, Ti-6Al-6V{{6} }Sn thiab Ti-8Al-1V-Mo. Ti-6Al{11}}V alloy yog cov khoom siv kub kub zoo heev uas siv los tsim cov dav hlau thiab foob pob hluav taws. Nws muaj nuj nqis heev hauv Tebchaws Meskas, thiab nws cov khoom tso tawm rau ntau tshaj li ib nrab ntawm titanium-based vanadium alloys. Hlau vanadium kuj tseem siv tau rau hauv cov khoom sib nqus, cam khwb cia hlau, cemented carbide, superconducting cov ntaub ntawv thiab cov ntaub ntawv nuclear reactor.
