1. Nqi -sensitive siv steels
FeV40 yog siv dav hauvrebar, hlau pas nrig, thiab dav siv steelsqhov twg cov kev cai metallurgical tsis nruj li hauv microalloyed lossis automotive steels.
Cov laj thawj zoo rau xaiv FeV40 suav nrog:
tus nqi qis dua ib ton,
dav dav,
yoo mov noj,
txaus cov ntsiab lus vanadium rau nruab nrab ntxiv dag zog.
Rau cov mills uas tsim cov qauv-qib rebar lossis cov qauv txheej txheem, FeV40 muaj txoj hauv kev lag luam kom tau raws li lub hom phiaj muaj zog.
2. Steelworks uas nyiam siab - ntim alloying yooj
Vim tias FeV40 muaj vanadium tsawg dua, txhua qhov sib ntxiv ua rau V tsawg dua rau cov yaj.
Qhov no ua rau cov neeg ua haujlwm tau yooj yim dua rau:
zoo -tu vanadium theem,
kho thaum tapping,
zam dhau -alloying,
teb rau - lub sij hawm xeem cov txiaj ntsig.
Rau cov khw muag khoom yaj uas nquag kho chemistry ntawm yoov, FeV40 muab kev tswj kom zoo dua piv nrog cov siab - ntom alloys zoo li FeV80.
3. Daim ntawv thov qhov kev hloov pauv ntawm vanadium rov qab tau txais
FeV40 yog siv rau hauv cov xwm txheej uas rov qab hloov pauv tsis cuam tshuam rau cov khoom zoo.
Piv txwv muaj xws li:
nruab nrab - steels,
qib qis alloy steels,
steels uas tsis tas yuav nruj microstructure tswj.
Hauv cov xwm txheej no, FeV40 sib xyaw ua haujlwm nrog kev pheej yig.
4. Foundry thiab casting daim ntaub ntawv
Foundries qee zaum xaiv FeV40 rau:
nruab nrab alloying ntawm cam khwb cia hlau,
ua tiav qhov cuam tshuam tsis kam,
txhim kho cov yam ntxwv ntawm hnav lossis hardness.
Nws qhov qis vanadium ntom ntom yog qhov tseem ceeb thaum tsuas yog kev hloov kho me me uas xav tau yam tsis tau tshaj tawm lub hom phiaj vanadium.
5. Vim li cas thiaj xaiv FeV40 hloov FeV50 lossis FeV80?
FeV40 feem ntau yog xaiv rauvim nyiaj txiag thiab kev ua haujlwm:
Tsawg alloying nqi
Kev tswj tshuaj tau yooj yim dua
Muaj txaus vanadium rau cov dav dav - lub zog steels
Muaj dav dav hauv qee thaj tsam
Tsawg qhov kev pheej hmoo ntawm pov tseg vim overdosing
Hauv siab-kawg steels, FeV80 yog tus qauv ntsuas; nyob rau hauv nruab nrab-ntau yam steels, FeV50 yog ib txwm muaj;
tab sis nyob rau hauv tus nqi- tsav ntau lawm,FeV40 muab qhov sib npaug zoo tshaj plaws.
6. Thaum FeV40 yuav tsis haum
Nws yog ib qho tseem ceeb kom nco ntsoov tias FeV40 tsis zoo rau:
HSLA steels yuav tsum tau ua kom cov nplej zoo meej
automotive steels
qib pipeline
cov cuab yeej steels lossis hnav-cov hlau tsis muaj zog
Cov ntawv thov no cia siab rau qhov ruaj khov vanadium rov qab thiab siab dua V ntom -ib yam dab tsi FeV40 tsis tuaj yeem muab tau zoo.
Hais txog peb cov khoom
Yog tias koj tab tom tsim cov hlau los yog cov hlau alloy dav dav thiab xav tau cov tswv yim, tus nqi - siv tau los ntawm vanadium, FeV40 feem ntau yog qhov kev xaiv pheej yig tshaj plaws.
Peb muabFeV40, FeV50, FeV60, thiab FeV80nrog chemistry zoo ib yam, txhim khu kev qha muaj, thiab hloov pauv hloov pauv qhov rais.
Qhia kojqib, kom muaj nuj nqis, qhov chaw, thiab lub qhov rais xa khoom, thiab kuv yuav npaj cov lus qhia meej, sib tw kom koj tuaj yeem sib piv cov kev xaiv sai sai thoob plaws plaub qib ferrovanadium.
