Txhais thiab Cov Khoom Tseem Ceeb ntawm Ferrovanadium
Ferrovanadium (FeV)yog ibhlau -vanadium alloyfeem ntau muaj35% -80% vanadium (V). Nws yog ib qho tseem ceeb tshaj plawsvanadium additiveshauvsteel kev lag luam. Ferrovanadium yog xa hauvpoblos yoggranulardaim ntawv nrog nyiaj -greymetallic luster.
Vanadiumyog atsis tshua muaj hlauuas muab cov haujlwm tshwj xeeb suav nrognplej refinement, txhawb zog, kev txhim kho toughness, thiabcorrosion kuj. Ntiaj teb no txhua xyoo vanadium ntau lawm yog kwv yees li100,000 tonnes, uas hais txog90%yog tsim raws liferrovanadium (FeV)siv rau hauvhlau alloys.
II. Cov khoom qib thiab National Standards
Suav teblub teb chaws tus qauvrau ferrovanadium yogGB/T 4139-2012, uas qhiakev cai, kev sim, kev tshuaj xyuas, ntim, cim, khaws cia, thiabdaim ntawv pov thawj zoo.
Raws li tus qauv no, ferrovanadium tau muab faib uacuaj qibnyob ntawmcov ntsiab lus ntawm vanadiumthiabcov ntsiab lus impurity:
| Qib | V (%) | C (%) Tsawg dua lossis sib npaug | Si (%) Tsawg dua lossis sib npaug | P (%) Tsawg dua lossis sib npaug | S (%) Tsawg dua lossis sib npaug | Al (%) Tsawg dua lossis sib npaug |
|---|---|---|---|---|---|---|
| FeV50-A | 48.0-55.0 | 0.40 | 2.0 | 0.06 | 0.04 | 1.5 |
| FeV50-B | 48.0-55.0 | 0.60 | 3.0 | 0.10 | 0.06 | 2.5 |

| FeV80-A | 78.0-82.0 | 0.15 | 1.5 | 0.05 | 0.04 | 1.5 |
| FeV80-B | 78.0-82.0 | 0.30 | 1.5 | 0.08 | 0.06 | 2.0 |
| FeV80-C | 78.0-82.0 | 0.30 | 1.5 | 0.08 | 0.06 | 2.0 |
Cov khoom tseem ceeb feem ntau yog categorized los ntawmcov ntsiab lus ntawm vanadiumua peb hom:35%-48% V, 48%-60% V, thiab70-85% V.
Rauparticle loj xav tau, ferrovanadium yog xa hauvpoblos yoggranulardaim ntawv, nrog ntau qhov loj me ntawm10-50 hli.
III. Strategic Position nyob rau hauv Steel Kev Lag Luam
Ferrovanadium yog ib qho tseem ceebtswv yim raw khoomrau covniaj hnub steel kev lag luam. Raws li iballoy additive, nws yog feem ntau siv nyob rau hauv zus tau tej covsiab-lub zog qis- alloy (HSLA) steel, cuab yeej steel, thiabvanadium microalloyed hlau.
