Cov qib ntawm Ferro Vanadium

1. High-Qib Ferrovanadium (FEV80 & FEV75)

Vanadium ntsiab lus: 75-85% (FEV80 feem ntau muaj 78-82% v, thaum FEV75 muaj 70-75% v).

Impurities: qib qis ntawm cov pa roj carbon (<0.15%), sulfur (<0.05%), and phosphorus (<0.05%).

Cov ntawv thov: Siv rau hauv cov kev siv ntau tshaj plaws alloys, Aerospace cov hlau, thiab cov khoom lag luam hlau uas muaj zog dua yog qhov tseem ceeb.

2. Nruab nrab-qib Ferrovanadium (FEV50 & FEV60)

Vanadium ntsiab lus: 50-65%.

Impurities: me ntsis cov pa roj carbon ntau dua (<0.4%) and silicon (<2.0%) compared to high-grade FeV.

Cov Kev Siv: Tib yam hauv kev tsim kho cov hlau, xa xov, thiab tsheb kho tsheb kom muaj zog thiab muaj zog.

3. Tsawg-qib Ferrovanadium (FEV40 & hauv qab)

Vanadium ntsiab lus: 35-45%.

Impurities: ntau dua carbon (<0.6%) and silicon (<3.0%), but more cost-effective.

Cov ntawv thov: Siv nyob rau hauv kev txhawb nqa cov tuav (rebar), dav dav qauv hlau, thiab cam khwb cia hlau rau kev ntxiv me ntsis.

Qib Tshwj Xeeb (Nitrided Fev, Fev-Al alloys)

Nitrided Fev: muaj vanadium nitride (vn) rau microalloyed steels xav tau cov qoob loo gragined.

Fev-Al alloys: siv hauv titanium alloys thiab cov vuam vuam hluav taws xob.

Qhov kev xaiv ntawm qib yog nyob ntawmTus nqi, yuav tsum tau Vanadium cov ntsiab lus, thiab cov txheej txheem steelmakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakakingCov. High-qib fev yog nyiam rau cov ntawv thov tseem ceeb, thaum low-qib fev yog yig rau bulk ntau lawm.
