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 |
Daim Ntawv Thov-Kev Kawm Tshwj Xeeb
(1) Qib steelmaking
HSLA hlau: Fev50 / FEV60 rau kev tsim kho thiab xa xov.
Tuam & Tuag Hlau: Fev80 rau coj Kuj (piv txwv li, HSS, D2 Cuab Yeej Hlau).
(2) alloys tshwj xeeb
Titanium-Aluminium-Vanadium (Ti -6 al {{3} v): Aerospace-Qib Fev80.
Vanadium redox roj teeb (vrfbs): Ultra-high-purity-purity vanadium electrolyte (99.9% v).
Cheeb Tsam & Txheej Txheem Kev Lag Luam
Txawv tebchaws / kev lag luam tswj hwm cov lus qhia tshwj xeeb:
| Lub hom phiaj | Cov qhab nia sib npaug | Yuav tsum tau ua |
|---|---|---|
| ASTM A1027 (US) | FEV40, FEV50, FEV80 | Nruj liulfur / phosphorus txwv |
| ISO 5451 (EU) | FEV50, FEV60 | Qhov tseem ceeb ntawm cov titanium (ti<0.05%) |
| GB / T 4139 (Suav Teb) | FEV40, FEV80 | Tso cai ntau dua silicon cov ntsiab lus |
Xwm Txheej & Niche Pawg
Rov ua ferrovanadium: Siv los ntawm steel slag lossis siv catalysts (~ 20% qis dua v cov ntsiab lus).
Nanopowder fev: Rau kev tsim khoom ntxiv (grain loj<100 nm).
