Ferrovanadium FeV50 thiab FeV80 soj ntsuam thoob plaws Suav lag luam loj
Thaum lub Cuaj Hlis 7, 2023, Suav kev lag luam ferrovanadium hauv Suav teb tau raug soj ntsuam raws li khov kho. Ob qho ntawm cov qib kev lag luam nquag, FeV50 thiab FeV80, tau tshaj tawm nyob rau hauv qhov chaw uas rov ua dua hnub kev ntsuam xyuas dhau los, thiab tsis muaj cheeb tsam tshaj tawm ib hnub - ntawm - hnub txav. Tag nrho cov txiaj ntsig hauv tsab xov xwm no tau hais nyob rau hauv units ntawm 10,000 CNY ib metric ton, se suav nrog, raws li kev sib hais haum ntawm daim nqi txais nyiaj hauv tuam txhab.
FeV50 ntau yam tau soj ntsuam sib npaug ntawm 10.7-11.0 rau kev lag luam tseem ceeb thiab 10.8-11.0 rau cov lus tshaj tawm thoob plaws Panzhihua hauv Sichuan, Jinzhou hauv Liaoning, Xinyu hauv Jiangxi, thiab Hubei, Hebei, Henan, Hunan thiab Jiangsu. Lub uniformity yog nws tus kheej lub teeb liab: thaum yim cais lub regional kev lag luam luam tawm ntau yam nyob rau tib hnub, lub regional arbitrage tau kaw thiab mov yog txuam zeb xav tau ntawm ib tug ntau clearing theem.

Nyeem qhov FeV50 rau FeV80 Kis
Ob qib tsis raug nqi rau ib qho yooj yim ntau yam ntawm vanadium cov ntsiab lus. FeV80 nqa txog 80% vanadium tawm tsam kwv yees li 50% rau FeV50, tab sis nws cov lus hais txog qib 17.12-17.6 tsawg dua ob npaug ntawm FeV50 qib ntawm 10.7-11.0. Qhov sib txawv ntawm cov khoom siv ntxiv ntawm vanadium ntxiv rau cov nqi kho kom zoo uas xav tau kom ncav cuag cov ntsiab lus siab dua, thiab nws tau cuam tshuam ntxiv los ntawm lub pas dej me me ntawm cov neeg tsim khoom tuaj yeem ua rau qib siab. Rau kev ua haujlwm steel, kev lag luam tawm ncaj qha: FeV80 qhia ntau vanadium ib tonne ntawm tus nqi thiab tsawg dua hlau khaws, uas tseem ceeb thaum tshav kub kub muaj qhov sib npaug hlau nruj; FeV50 muaj ntau dua thiab yooj yim rau qhov chaw ntawm kev ceeb toom luv luv.
Qib thiab Standards
| Qib | Nominal V cov ntsiab lus | Hom kev siv |
|---|---|---|
| FeV 40 | txog 40% | General steel alloying qhov twg qis dua - nqi vanadium units tau txais |
| FeV 50 | txog 50% | Qib kev lag luam feem ntau; microalloyed rebar, HSLA phaj thiab structural steel |
| FeV 60 | txog 60% | Siab dua -yielding alloying rau kev thov steel chemistry |
| fwv 80 | txog 80% | High vanadium tawm los nrog qis hlau nqa; tshwj xeeb steels thiab titanium- txoj kev alloy |
Kev txwv kev txwv rau vanadium, carbon, silicon, aluminium, phosphorus thiab sulfur yog teev nyob rau hauv Suav teb los ntawm GB / T 4139. Rau kev lag luam thoob ntiaj teb, ASTM A102 thiab ISO 5451 yog cov ntaub ntawv ib txwm hais rau ferrovanadium specification thiab kev xa khoom. Kev yuav khoom tshwj xeeb yuav tsum muaj npe rau qib, cov ntsiab lus ntawm vanadium kam rau ua thiab tus neeg tsis huv qab nthab, vim tias cov ceilings txiav txim siab qhov sib ntxiv loj tshaj plaws uas tuaj yeem ua yam tsis muaj kev cuam tshuam cov hlau chemistry.
Vim li cas Vanadium Matters hauv Steel
Vanadium yog ib qho muaj zog carbide thiab nitride yav dhau los thiab ib qho ntawm cov nqi tshaj plaws -zoo microalloying ntxiv muaj rau cov kws tsim steel. Ntxiv ntawm kwv yees li 0.02% rau 0.15%, nws ua haujlwm los ntawm ob lub tshuab. Kev ua kom muaj zog los nag tshwm sim thaum nplua vanadium carbonitride particles tsim thaum dov thiab txias. Grain refinement tshwm sim thaum vanadium nitride particles pin austenite lis ciam teb thaum kub ua hauj lwm, tawm hauv ib tug finer thiab tougher zaum kawg microstructure. Ua ke lawv muab lub zog siab dua nrog cov nqi qis dua thiab zoo dua weldability dua li qhov hnyav ntxiv ntawm qhov tsis muaj zog ntxiv.
Cov khoom siv zoo xws li HRB400 thiab HRB500 siab - lub zog rebar ua rau GB/T 1499.2, HSLA structural phaj, linepipe steel, caij nplooj ntoos hlav steel, vanadium-alloyed tool thiab tuag steels, thiab siab - qib cam khwb cia hlau. Lub zog siv tau rau tus neeg yuav khoom yog qhov qhia txog qib kom yog cia lub hom phiaj lub zog tau ntsib nrog qhov tsawg tshaj plaws vanadium ntxiv, uas yog lub ntsiab lus tseem ceeb ntawm cov nqi alloy.
Daim ntawv teev kev yuav khoom
Qib thiab chemistry:xeev FeV40, FeV50, FeV60 los yog FeV80, lub vanadium kam rau ua thiab impurity txwv, referencing GB/T 4139, ASTM A102 los yog ISO 5451.
Loj thiab ntim:paub meej tias cov pob loj, feem ntau 10-50 hli, lossis cov hmoov mesh yuav tsum tau, ntxiv rau cov hnab ntim khoom tiv thaiv dej los yog cov nruas steel ntawm qhov hnyav hnyav.
Kev txheeb xyuas:Npaj cov qauv kev ywj pheej thiab tshuaj ntsuam xyuas los ntawm lub chaw kuaj pom zoo thiab pom zoo cov qauv kev lees paub ua ntej.
Cov ntsiab lus daws teeb meem:kev lees paub- cov nqe lus them nqi thiab nyiaj ntsuab tsim cov nqi sib txawv, yog li txhim kho lub hauv paus hauv daim ntawv cog lus es tsis yog hauv daim ntawv xa nyiaj.
Sijhawm sijhawm:ferrovanadium raug soj ntsuam txhua hnub tiv thaiv tus nqi pub khoom noj thiab kev yuav zeb, yog li cov ntaub ntawv siv tau yuav tsum tau rov qab- tshuaj xyuas ua ntej nws siv hauv kev sib tham nyob.

Qhov kev sib kis qhia txog qhov ntxiv vanadium units ntxiv rau cov nqi kho kom zoo, tsis yog cov ntsiab lus ncaj nraim, thiab nws kuj tseem cuam tshuam cov neeg tsim khoom nqaim rau qib siab dua.
Q: Cov cheeb tsam twg tau them los ntawm FeV50 kev ntsuas?
Panzhihua, Jinzhou, Xinyu, Hubei, Hebei, Henan, Hunan thiab Jiangsu, tag nrho cov ntawv luam tawm tib yam ntawm hnub ntsuas.
Q: Cov qauv twg siv rau ferrovanadium?
GB / T 4139 nyob rau hauv Suav teb, nrog ASTM A102 thiab ISO 5451 ib txwm hais rau thoob ntiaj teb specification thiab xa khoom.
Q: Puas yog cov kev ntsuas 2023 no tseem siv tau raws li tus nqi tam sim no?
Tsis yog. Lawv yog keeb kwm siv ntau yam. Ferrovanadium txav nrog tus nqi pub khoom noj thiab kev yuav zeb, yog li yuav tsum muaj kev ntsuas tam sim no rau ib daim ntawv cog lus tshiab.
