60 Ferro Vanadium

Ferro vanadium 60yog ib qho alloy tau los ntawm kev txo qis, nrog cov ntsiab lus vanadium tsis tsawg dua 35.0% thiab tsis ntau tshaj 85.0%. Lub vanadium uas muaj hlau concentrate tau los ntawm kev pab ntawm vanadium titanium magnetite ore raug xa mus rau sintering thiab ironmaking txheej txheem kom tau txais vanadium uas muaj hlau molten. Lub vanadium uas muaj molten hlau yog ces muab rho tawm los ntawm converter kom tau vanadium slag, nrog ib tug vanadium rov qab tus nqi ntawm 46.28%. Yog tias kev siv dav dav ntawm steel slag thiab lwm yam raug txiav txim siab, qhov tseeb ntawm vanadium rov qab tus nqi yog me ntsis siab dua qhov no, mus txog ntau dua 53%. Vanadium slag tau dhau los ua cov txheej txheem xws li roasting, leaching, thiab vanadium nag lossis daus kom tau ammonium polyvanadate. Ammonium polyvanadate tau dhau los ua cov txheej txheem xws li roasting thiab txo kom tau V2O5 lossis V2O3, uas yog ntxiv txo los ntawm electro aluminothermal txoj kev los tsim ferrovanadium.

Cov txheej txheem ntau lawm thiab khoom siv rau silicon thermal smelting ntawm ferrovanadium:

Cov khoom siv raw siv hauv cov txheej txheem silicon thermal yog raws li hauv qab no:

V2O5: Thickness tsis tshaj 5mm, thaiv qhov loj tsis tshaj 200mm; Ferrosilicon: feem ntau yog siv 75% ferrosilicon nrog lub thaiv qhov loj ntawm 20-30 hli;

Lime: should be well calcined, with effective CaO>85%, P<0.15%, and a block size of 30-50mm;

Aluminium thaiv: 30-40mm block loj;

Cov hlau khib nyiab: Cov hlau khib nyiab los yog cov hlau nplaum hlau nplaum xaiv los ntawm vanadium slag yuav tsum huv thiab tsis xeb. Cov hlau khib nyiab lossis lwm cov khoom siv hlau zoo kuj tuaj yeem siv tau, tab sis cov ntaub ntawv no yuav tsum muaj C Tsawg dua lossis sib npaug ntawm 0.5% thiab P Tsawg dua lossis sib npaug rau 0.035% .

Production process flow:

Lub tshuab smelting ferrovanadium siv hluav taws xob silicon thermal txoj kev yog cov paub tab, thiab smelting yog nqa tawm nyob rau hauv ib tug hluav taws xob arc rauv;
Lub sij hawm txo tau muab faib ua lub sij hawm txo thiab lub sij hawm ua kom zoo. Lub sij hawm txo tau muab faib ua ob theem smelting thiab thib peb theem smelting txoj kev. Cov hlau silicon ntau dhau yog siv los txo cov slag refined ntawm lub cub tawg kom txog thaum lub slag muaj tsawg dua 0.35% V2O5. Cov khib nyiab pov tseg tau tawm ntawm qhov cub kom pib ua kom zoo, thiab tom qab ntawd sib tov ntawm vanadium pentoxide thiab txiv qaub ntxiv rau kev ua kom zoo.
Thaum Si cov ntsiab lus nyob rau hauv cov hlau yog tsawg dua 2%, lub refined slag tawm muaj 10% ~ 15% V2O5 thiab xa rov qab mus rau lub cub tawg tom ntej siv.
