Q1. Qhov "50" hauv FeV50 txhais tau li cas?
Qhov "50" sawv cev rau tuscov ntsiab lus ntawm vanadiumnyob rau hauv cov alloy-kwv yees50% V los ntawm huab hwm coj.
Nws uatsis yogpiav qhia txog purity, melting kub, los yog efficiency.
Nws tsuas qhia ntau npaum li cas cov ntsiab lus vanadium cov hlau xa tuaj thaum ntxiv rau cov hlau molten.
Nov yog qhov sib piv nrawm thoob plaws qib ferrovanadium:
| Qib | Hom Vanadium Cov ntsiab lus (%) |
|---|---|
| FeV 40 | ~40% |
| FeV 50 | ~50% |
| FeV 60 | ~60% |
| fwv 80 | ~78–82% |
Vim hais tias vanadium yog cov khoom nquag, qhov feem pua ncaj qha txiav txim siab npaum li cas cov hlau yuav tsum raug them kom ncav cuag lub hom phiaj V cov ntsiab lus hauv cov hlau.
Q2. Vim li cas vanadium feem pua tseem ceeb heev rau steelmakers?
V% tswj ntau npaum li cas ferrovanadium ib lub zeb yuav tsum tau noj. Txij li thaum FeV50 muaj ib nrab ntawm vanadium, muab khoom1 kg ntawm vanadiumyuav tsum roughly2 kq fev50, kho los ntawm tus nqi rov qab.
Cov qib V siab dua txo cov tonnage lub cev ntxiv, tab sis lawv yuav tsis tas li tus nqi ntau dua -zoo nyob ntawm kev ua lag luam thiab cov cwj pwm yaj. Qhov no yog vim li cas FeV50 tseem yog qhov kev xaiv tseem ceeb: kev kwv yees muaj pes tsawg leeg, muaj nyob ruaj khov, thiab nkag siab dav dav cov qauv rov qab.
Q3. Puas yog FeV50's vanadium cov ntsiab lus cuam tshuam rau yaj thiab rov qab los rau hauv qhov cub?
Indirectly, yog.
Thaum V% nws tus kheej tsis hloov qhov kub thiab txias heev, FeV50 nyiam muabbalanced dissolution cwj pwmvim nws qhov loj me (10–50 mm lossis 10–60 mm) thiab tswj cov impurity profile.
Ob pawg nrog tib V% tseem tuaj yeem coj txawv txawv yog tias granularity lossis impurities deviate. Rau feem ntau cov mills, qhov kev kwv yees V xa tuaj thiab tswj tau qhov ceev ntawm FeV50 muab cov vanadium rov qab zoo ib yam thoob plaws BOF, EAF, thiab ladle ntxiv.
Q4. Lwm qhov tshwj xeeb tseem ceeb dua li "50"?
Vanadium feem pua tsuas yog ib qho ntawm cov puzzle. Steelmakers saib ze rau ntawm impurity theem thiab granularity vim hais tias ob qho tib si cuam tshuam rau yield, slag cwj pwm, thiab kev tswj kev suav nrog.
| Specification Field | Vim Li Cas Nws Tseem Ceeb |
|---|---|
| Cov pa roj carbon (C) | Influences weldability thiab lub zog sib npaug. |
| Sulfur (S) thiab Phosphorus (P) | Tight txwv tiv thaiv brittleness thiab toughness poob. |
| Aluminium (Al), Silicon (Si) | Muaj feem cuam tshuam rau deoxidation thiab slag chemistry. |
| Particle loj | Txiav txim siab ceev ceev thiab vanadium rov qab. |
Hauv kev xyaum, ib lub zeb sib piv FeV50 los ntawm cov chaw muag khoom sib txawv feem ntau txiav txim siab raws li cov kev txhawb nqa no ntau dua li ntawm V% ib leeg.
Q5. Puas yog "50" pab txiav txim siab tus nqi alloy -kev ua tau zoo?
Zoo heev li.
Steelmakers feem ntau piv FeV50 nrog FeV60 lossis FeV80 tsis yog los ntawm tus nqi tab sis los ntawmtus nqi ib kilogram ntawm vanadium.
Vim tias FeV50 zaum hauv nruab nrab, nws feem ntau muaj qhov muaj nyob ruaj khov thiab kev kwv yees kev lag luam -tshwj xeeb tshaj yog thaum yaj rov qab thiab qhov loj me me sib xws.
Qhov no yog vim li cas "50" yog ntau tshaj li ib daim ntawv lo; nws txuas ncaj qha mus rau tus nqi noj, metallurgical efficiency, thiab tag nrho cov nqi alloy.
txog Peb
Yog tias koj tab tom ntsuas FeV50 rau koj txoj kev hlau, qhov tseem ceeb yog qhov sib pivqib, qhov loj me, thiab kev txwv tsis pub dhaurau koj lub cub tawg es tsis txhob cia siab rau qhov feem pua vanadium ib leeg.
Peb muab FeV40, FeV50, FeV60, thiab FeV80 nrog cov zis txhua hli ruaj khov thiab zoo sib xws.
Yog tias koj xav tau, kuv tuaj yeem pab koj txiav txim siab qib zoo thiab npaj cov lus hais meej meej -tsuas yog qhia:
qib / qhov loj / qhov ntau / qhov chaw / lub qhov rais xa khoom.
Kuv mam li muab cov lus qhia meej meej - sib npaug nrog rau COA cov ntsiab lus.
