Tus Qauv Kev Qhia Tawm los ntawm Vatadium Cov Ntsiab Lus
Ferrovanadium yog feem ntau cov grandorized raws nwsVanadium feem pua, nrog cov qib thoob ntiaj teb tau lees paub:
| Teem nqi | Vanadium (V) cov ntsiab lus | Key impurities(Max%) | Thawj cov ntawv thov |
|---|---|---|---|
| FEV80 | 78–82% | C: {{{0. 15%, SI: 1.5%, AL: 1.5% | Aerospace alloys, High-ceev steels, nuclear reactors |
| FEV60 | 58–65% | C: {{{{{0}}}}}}}}}}}}}}}}}}} | Tuam Txheem Hlau, Cheebtsam Automotive |
| FEV50 | 48–55% | C: {{{0. 60%, Si: 2.5%, AL: 2.5% | Cov Qauv Tsim Qauv (HSLA), Pipelines |
| FEV40 | 35–45% | C: {{{{{0}}}}. 75%,}}}}}%, al: 3.0% | Kev tsim kho dav dav, tus nqi them qis |

FEV80yog qib siab-huv tshaj plaws, qhov tseem ceeb rau cov ntawv thov tseem ceeb uas yuav tsum tau muaj kev cuam tshuam tsawg.
Qib qis (piv txwv li, fev40) ua ntej them tus nqi-efficiency rau bulk steel ntau lawm.
Kev faib tawm los ntawm cov txheej txheem ntau lawm
(1) AlleileSMic Ferrovanadium
Kev ua: Txo ntawmV₂o₅ (vanadium pentoxide)Siv txhuas hmoov thiab hlau seem.
Cov yam ntxwv:
Cov ntsiab lus muaj roj carbon tsawg (<0.1% in FeV80).
Siab purity tab sis lub zog-intensive.
Siv rau cov qhab nia hwm (FEV80 / FEV60).
(2) Silicothermic / Fais Arc Rauv (EAF) Ferrovanadium
Kev ua: Txo ntawm vanadium slag lossis oxides sivsilicon (si)lossiscarbon (c)nyob rau hauv ib eF.
Cov yam ntxwv:
Ntau dua cov pa roj carbon / silicon seem (piv txwv li, fev50 / txog40).
Nqi-ua tau zoo rau huab hwm coj ntau lawm.
Kev faib tawm los ntawm kev sib ntxiv & microalloys
Ferrovanadium yuav suav nrog cov kab tseem ceeb los txhim kho cov khoom tshwj xeeb:
| Ntaus | Qhov tseem ceeb ntxiv | Lub hom phiaj |
|---|---|---|
| Nitrided fev | 3-6% nitrogen (n) | Txhim kho cov qoob loo qoob loo hauv HSLA hlau |
| High-al fev | 4-8% txhuas (al) | Txhim kho cov deoxidation hauv steelmaking |
| Qis-c fev | Pa roj carbon<0.05% | Tseem ceeb rau ultra-high-zog alloys |
