Q1. Dab tsi yog qhov tseem ceeb ntawm qhov sib txawv uas cuam tshuam rau kev rov qab los?
Vanadium density drives ob qho tib si dosing precision thiab yaj cwj pwm.
| Qib | Kwv yees li. V Cov ntsiab lus | Kev cuam tshuam tam sim ntawd |
|---|---|---|
| FeV 50 | ~50% V | Kev zam txim ntau dua; loj ntxiv pawg txhim kho dispersion |
| FeV 60 | ~60% V | Kev ceev dua; yuav tsum tau txhaj tshuaj nruj dua thiab khov kho |
Ntau dua vanadium concentration txhais tau hais tias FeV60 xa ntau V ib kilogram, tab sis kuj ua rau nws rhiab heev rau qhov hloov pauv ntawm lub cub tawg.
Q2. FeV50 thiab FeV60 txawv li cas hauv vanadium rov qab?
FeV50 zoo li ua tiavruaj khov duahla cov cua sov vim nws yaj sai dua thiab tsis tshua cuam tshuam los ntawm kev hloov pauv ntawm slag.
FeV50 Cov yam ntxwv rov qab
Ceev dissolution thaum tapping
Tsawg oxidation raug
Ua haujlwm zoo thoob plaws qhov kub thiab txias
Yam tsawg kawg nkaus ntawm undissolved residues
FeV60 Cov yam ntxwv rov qab
Muaj zog rov qab nyob rau hauv siab, khov kho kub
Slower melting nce rhiab heev rau slag oxidation
Nws tuaj yeem tsim qhov hloov pauv rov qab thaum lub tshuab hluav taws xob hloov pauv
Yuav tsum muaj kev qhuab ntuas lub sijhawm thiab nplawm
Hauv luv luv:FeV50=sib xws; FeV60=muaj peev xwm ntau dua tab sis qhov kev ua tau zoo dua.
Q3. Vim li cas FeV60 thiaj li xav tau koob tshuaj ntau dua?
FeV60 nqa ntau dua vanadium ib kilogram, yog li txawm tias me me yuam kev tsim V viav vias loj hauv cov hlau.
Qhov txawv tseem ceeb:
| Dosing Factor | FeV 50 | FeV 60 |
|---|---|---|
| rhiab heev rau dosing yuam kev | Tsawg- nruab nrab | Siab |
| Kev cuam tshuam ntawm granularity | Nruab nrab | Muaj zog |
| Xav tau lub sij hawm nruj ntxiv | Tsawg | Siab |
| Kev cuam tshuam ntawm slag thickness | Nruab nrab | Siab |
FeV50 qhov kev ua siab ntev ntev ua rau nws tsim nyog rau cov khw muag khoom BOF / EAF nrog cov khoom sib xyaw thiab cov khoom sib txawv.
FeV60 ua tau zoo tshaj qhov uas tswj nruj thiab dov lub sij hawm zoo ib yam.
Q4. Kev sib cuam tshuam ntawm slag-hlau cuam tshuam li cas rau ob qib sib txawv?
Slag chemistry txiav txim siab npaum li cas vanadium nyob hauv cov hlau piv rau oxidizes rau hauv slag.
FeV 50:dissolves sai → txo lub sij hawm sib cuag nrog oxidizing slag → muaj zog, txhim khu kev qha rov qab.
FWV 60:dissolves qeeb → ntev raug rau FeO / MnO → siab dua ntawm oxidation poob.
Qhov no yog vim li cas FeV60 ua haujlwm zoo tshaj plaws nrog:
nyias, kua slag
qis FeO qib
muaj zog ladle stirring
ruaj khov tapping kub
Thaum slag tsis sib haum, FeV50 outperforms FeV60 yuav luag txhua zaus.
Q5. Qib twg muaj qhov zoo tshaj plaws ua ke ntawm kev rov qab + dosing stability?
Tsis muaj universal yeej; Qhov kev xaiv raug yog nyob ntawm cov txheej txheem txheej txheem:
XaivFeV 50thaum:
tapping kub sib txawv ntawm cov cua sov- mus rau - cua sov
slag oxidation yog qhov nyuaj rau tswj
dosing precision nyob ntawm qhov loj ntxiv loj
cov neeg ua haujlwm saib xyuas qhov tseem ceeb ntawm kev rov zoo ib yam li theoretical efficiency
XaivFeV 60thaum:
kub, nplawm, thiab slag tej yam kev mob yog nruj nreem tswj
alloy qhov rais xav tau V ceev dua
mills xav txo qhov hnyav ntxiv nrog kev kwv yees tau yaj
FeV60 yog ib qho kev ua tau zoo - kev xaiv, tab sis FeV50 yog qhovntau zam txim qib industrial.
txog peb
Yog tias koj txiav txim siab ntawm FeV50 thiab FeV60, qhov kev xaiv zoo tshaj yog nyob ntawmkoj lub qhov cub kub qhov rais, slag stability, stirring zog, thiab dosing yuav tsum tau-tsis yog V feem pua ntawm daim ntawv lo.
Peb muab FeV40, FeV50, FeV60, thiab FeV80 nrog tswj granularity thiab nruj impurity txwv kom paub tseeb tias tus cwj pwm ntawm vanadium.
Yog hais tias koj xav tau ib tug yaj- txoj kev- sib tw cov lus pom zoo los yog cov ncauj lus kom ntxaws, tsuas qhia:
qib / qhov loj / ntau / qhov chaw / lub qhov rais xa khoom.
