Q1. Puas yog FeV50 lees paub tias yog qib tus qauv hauv cheeb tsam tsim khoom loj?
Yog-FeV50 yog dav lees paub tias yog ib qhomainstream coj mus muag qibthoob plaws Asia, Europe, thiab Americas.
Feem ntau lub teb chaws thiab kev lag luam specifications muaj xws li 50% vanadium ferroalloy variant vim nws sib npaug tus cwj pwm melting, vanadium ntom, thiab impurity tswj nyob rau hauv ib txoj kev uas haum rau BOF thiab EAF ntau lawm.
Ib qho yooj yim saib ntawm cov qib FeV ntau npaum li cas thoob ntiaj teb:
| Thaj tsam | Feem ntau siv qib |
|---|---|
| Asia | FeV 40,FeV 50, FWV 60 |
| Teb chaws Europe | FeV 50, fwv 80 |
| Tebchaws Asmeskas | FeV 50, FWV 60 |
FeV50's broad hneev taw yog ib feem keeb kwm, ib feem kev ua haujlwm - thiab feem ntau yog tsav los ntawm nws txoj kev sib raug zoo nrog ntau hom hlau.
Q2. Vim li cas FeV50 tau dhau los ua lub hauv paus hauv ntiaj teb tsis yog FeV40 lossis FeV60?
Peb lub laj thawj tswv yim piav qhia nws txoj kev tswj hwm:
Balanced vanadium cov ntsiab lus
FeV40 yuav tsum muaj ntau dua ntxiv; FeV60 xav tau kev siv tshuaj nruj dua.
FeV50 muaj qhov "hauv nruab nrab" ntau mills nyiam.
Kev xav rov qab los
Thoob plaws BOF, EAF, thiab ladle ntxiv, FeV50 feem ntau qhia txog qhov ruaj khov tshaj plaws ntawm vanadium rov qab qauv ua tsaug rau nws qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom (10-50 hli / 10-60 hli).
Keeb kwm kev saws
Ntau lub mills steel tsim lawv cov qauv dov, lub zog nkhaus, thiab kev ua kom zoo nyob ib puag ncig FeV50 xyoo dhau los.
Hloov cov qhab nia yuav xav kom rov ntsuas tag nrho cov tshuab metallurgical, yog li FeV50 tseem yog tus qauv ntawm inertia-thiab los ntawm kev ua tau zoo.
Q3. Puas yog impurity tswj rau FeV50 raws li thoob ntiaj teb cov neeg xa khoom?
Thaum lub sij hawm impurity sib txawv me ntsis los ntawm cov neeg tsim khoom, FeV50 feem ntau muajzoo -txhais txwvrau carbon, sulfur, phosphorus, aluminium, thiab silicon. Vim hais tias cov mills siv nws nyob rau hauv siab - ntim daim ntawv thov xws li kev tsim steel thiab HSLA phaj, cov neeg muag khoom tswj xyuas cov ntaub ntawv tsis huv.
Cov lus piav qhia impurity xav txog rau FeV50:
| Impurity Teb | Yam Kev Cia Siab |
|---|---|
| Cov pa roj carbon | Tswj los tiv thaiv weldability. |
| Sulfur, phosphorus | Qib qis kom tswj tau qhov toughness. |
| Aluminium, Silicon | Tswj kom ruaj khov deoxidation tus cwj pwm. |
| Cov kab ke | Khaws nqaim kom tsis txhob muaj teeb meem suav nrog. |
Qhov kev sib raug zoo no txhawb nqa FeV50 txoj cai raws li kev ntseeg siab thoob ntiaj teb - qib alloy.
Q4. Puas yog "tus qauv thoob ntiaj teb" txhais tau tias FeV50 siv rau txhua qib steel?
Tsis raws nraim.
FeV50 yog tus qauv qib hauv covkev ua lag luam, tsis yog tag nrho -lub hom phiaj kev daws teeb meem. Kev lag luam txais nws vim nws ua haujlwm zoo rau:
kev tsim steels (rebar, seem),
siab-lub zog qis- alloy phaj,
pipeline steels,
automotive structural Cheebtsam.
Tab sis cov mills xav tau kev txhaj tshuaj nruj heev los yog ultra- siab vanadium rov qab qee zaum nyiam FeV60 lossis FeV80 hloov.
Yog li FeV50 yog qhovua ntej, tsis yog kev xaiv siv tau xwb.
Q5. Puas yuav FeV50 tseem yog qib tseem ceeb yav tom ntej?
Muab cov kev coj ua tam sim no, dov thev naus laus zis, thiab kev lag luam hlau alloy, FeV50 zoo li yuav nyob hauv lub ntiaj teb lub hauv paus rau yav tom ntej. Nws qhov sib npaug ntawm vanadium concentration, melting cwj pwm, thiab cov khoom muaj ua rau nws nyuaj los hloov yam tsis muaj kev cuam tshuam cov tsim steelmaking workflows.
Tshwj tsis yog tias cov tswv yim alloy hloov pauv tau zoo heev, FeV50 yuav txuas ntxiv mus ua lub ntiaj teb cov tswv yim tshaj plaws thiab siv dav hauv qib ferrovanadium.
