Q1. Dab tsi yog qhov tseem ceeb sib txawv uas cuam tshuam rau kev tawg?
Qhov txawv tseem ceeb yogvanadium ceev.
FeV80 muaj kwv yees li78-82% vanadium, thaum FeV50 muaj nyob ib ncig ntawm50%.
Qhov no hloov ob yam:
Melting dynamics- FeV80 yog denser thiab melts qeeb dua.
Thaum tshav kub kub nqus ib kilogram- FeV80 yuav tsum tau thermal input kom yaj tag.
Ib qho yooj yim txheej txheem cej luam:
| Qib | Kwv yees li. V% | Tus txheeb ze Dissolution Rate |
|---|---|---|
| FeV 50 | ~50% | Faster, ntau uniform |
| fwv 80 | ~78–82% | Tsawg dua, kub dua -nyob |
Qhov sib txawv no tau tshaj tawm thaum tapping lossis lig - theem ntaiv ntxiv.
Q2. Vim li cas FeV50 yaj sai dua nyob rau hauv feem ntau ntawm cov cua sov txoj kev?
Peb lub tswv yim yog vim li cas:
Tsawg ceev:FeV50 nyob thiab melts sai dua, tshwj xeeb tshaj yog nyob rau hauv BOF thiab EAF tapping ntws.
Common size ranges:FeV50 yog dav siv nyob rau hauv 10-50 mm los yog 10-60 mm qhov ntau thiab tsawg uas sib npaug thaj tsam ntawm qhov chaw thiab melting stability.
Tsawg vanadium concentration:Tsawg cua sov yuav tsum tau ib kilogram ntawm alloy.
Qhov no ua rau FeV50 zam ntau dua nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias.
Q3. Thaum twg FeV80 qhov kev tawg qeeb qeeb dhau los ua qhov nyuaj?
FeV80 tuaj yeem nkag siab raws li qee yam xwm txheej:
kais luv luv - rau - lub sijhawm hloov pauv,
qis dua - dua - qhov ntsuas kub zoo tshaj plaws,
tuab lossis siab -viscosity slag txheej,
rauv txoj kev nrog tsawg stirring.
Yog tias kev sib cais tsis tiav, cov neeg ua haujlwm yuav pom:
txo vanadium rov qab,
qeeb alloy homogenization,
VC/VN nag xob nag cua lub sij hawm.
Vim tias FeV80 yog qhov ntom ntom, cov seem seem yuav nyob ntev dua ua ntej ua kom tag nrho.
Q4. Yuav ua li cas FeV50 thiab FeV80 piv nyob rau hauv cov nqe lus ntawm vanadium rov qab?
Contrary to intuition, FeV80 uatsis ib txwmmuab kev rov qab zoo dua, txawm tias nws qhov ntau dua V concentration. Kev rov qab los nyob ntawm hnyav heevlub sijhawm tawgthiabkev sib cuam tshuam.
Kev sib piv cov tswv yim:
| Qhov xwm txheej | FeV50 Kev coj tus cwj pwm | FeV80 Tus cwj pwm |
|---|---|---|
| Kub yaj kub | Rov qab muaj zog | Rov qab muaj zog, tab sis pib qeeb |
| Nruab nrab kub | ruaj khov | Tej zaum yuav qhia txog kev ncua ib nrab |
| Thick slag npog | Kev cuam tshuam nruab nrab | Muaj zog cuam tshuam; siab dua oxidation |
| Fast tapping sequence | Ua haujlwm zoo | Muaj kev pheej hmoo ntawm kev ua tsis tiav melting |
Vim tias FeV80 nkag mus tom qab thiab yaj qeeb dua, nws tuaj yeem ntsib ntau dua oxidation nyob ze ntawm slag-hlau interface.
Q5. Thaum twg mills yuav tsum xaiv FeV50 vs FeV80 raws li tus cwj pwm sib cais?
Xaiv FeV50Thaum koj xav tau kev tawg sai sai, kev rov ua tau zoo, thiab qhov loj me uas haum rau BOF / EAF txoj haujlwm.
Xaiv FeV80thaum micro- alloying xav tauhigh vanadium ntomthiab koj tuaj yeem txhawb nqa nws qhov kev sib cais nrog qhov kub txaus, nplawm lub zog, lossis lub qhov rais melting ntev dua.
FeV80 ua rau kev txiav txim siab nruj - cov kev pab cuam noj tshuaj; FeV50 tseem yog qhov kev zam txim ntau dua rau kev siab - ntim txoj kev.
txog Peb
Yog tias koj piv FeV50 thiab FeV80 rau koj txoj kev yaj, qhov kev txiav txim siab yuav tsum muaj kev cuam tshuamkub profile, slag cwj pwm, yaj lub sij hawm, thiab rov qab lub hom phiaj-tsis yog feem pua ntawm vanadium xwb.
Peb muab FeV40, FeV50, FeV60, thiab FeV80 nrog tswj granularity kom ruaj khov.
Yog tias koj xav tau qhov tshwj xeeb -cov lus pom zoo sib xws lossis cov lus hais meej, tsuas yog qhia:
qib / qhov loj / qhov ntau / qhov chaw / lub qhov rais xa khoom.
Kuv mam li npaj cov ncauj lus kom ntxaws ua ke nrog cov ntaub ntawv COA.
