Dab tsi yog ferro niobium siv rau?
Ferrroniobium yog aNiobium - IT Hlau tus tswv AlloyFeem ntau ua haujlwm raws li aLis Feel thiab Ntxiv Desulding Tus Neeg Sawv CevNyob rau hauv high - kev ua tiav cov hlau thiab superalloys. Cov ntawv thov tseem ceeb muaj xws li:
A. Siab {{{{}} lub zog qis -} alloy (hsla) cov hlau (85% ntawm general fenb thov)
Microalloying: Ntxiv0.03-0.10% NBPab:
Qoob loo nplej: Niobium carbonitrides (NBC / NBN) PIN Austenite grainaries thaum kub dov, yielding ferrite ferrite nplej.
30-50% Ntau Tshaj Tawm Lub Zog(Piv txwv li, rajpelines, txuas hniav, skyscrapers).
Txhim kho kev nruj thiab weldability (tseem ceeb rau arctic pipelines zoo li trans - Neeg Alaska).
B. Stainless hlau (10% kev thov)
Raws cai: Tiv thaiv cov chromium carbide tsim hauv Austenitic qib (piv txwv li, 347, 321), txhim kho:
Corrosion Kuj (tshuaj lom neeg cov nroj tsuag, tso pa tawm).
High - kub lub zog (dav hlau tshuab sib xyaw).
C. Nickel -} Raws supallloys
Aerospace turbines: Niobium Cov Ntawv'' theem (ni₃nb)Hauv Inconel 718, muab:
Nkag los ntawm 700℃+.
Qeeb zog durability (rotor hniav, tom qab).
D. Cov ntawv thov tawm
Lub Tsheb Hluav Taws Xob Hluav Taws Xob: Niobium -}} {1} ion anodes (piv txwv li ™) rau ultra {{}} ceev them.
Tus superconductors: Ntshiab niobium los ntawm Fenb siv hauv MRI cov hlau nplaum thiab particle accelerators (Cern).
Dab tsi yog cov muaj pes tsawg leeg ntawm ferrroniobium?
Ferrroniobium feem ntau muaj60-70% niobium (nb), Sib npaug nrog hlau (FE) thiab tswj kev tsis sib haum xeeb. Cov Qauv Qauv:
| Lub ntsiab | Kev Sib Tw | Ua Haujlwm / Kev Cuam Tshuam |
|---|---|---|
| Niobium (nb) | 60–70% | Thawj tus neeg sawv cev |
| Tantalum (ta) | 0.5–3.0% | Co - tshwm sim nrog NB; siv tau nyob rau hauv feem ntau alloys |
| Hlau (FE) | 25–35% | Cov hlau rau kev sib cais hauv cov hlau |
| Silicon (si) | Tsawg dua los yog sib npaug rau 2.0% | Tau txais los ntawm ore / txo cov txheej txheem |
| Aluminium (AL) | Tsawg dua los yog sib npaug rau 1.0% | Residual Los Ntawm Ntau Lawm |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0.05% | Tswj Rau Hlau Huv |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0.03% | Txo qis kom tiv thaiv kev ua kom sov |
Tsab ntawv: Tsawg -} qib txhuas(Tsis pub dhau los lossis sib npaug nrog 0.5%) yog siv rau hauv cov ntawv thov huv si (piv txwv li, cov ntawv txheeb xyuas tsheb).
Dab tsi yog melting point ntawm ferrroniobium?
Ferrroniobiummelts dhau ib tug ntauVim nws li xwm txheej, tsis zoo li cov ntsiab ntshiab:
Melting ntau: 1,528-1,560 degree(Sib txawv nrog kev sib xyaw).
Piv tau:
Ntshiab niobium melts ntawm2,468 degree(Siab tshaj plaws ntawm cov lag luam kev lag luam).
Hlau melts ntawm1,538 degree.
Qhov tseem ceeb:
Lub Fenb melting ntau yam tso cai xaus rau hauv Molten Steel (feem ntau 1,600-1,650 degree) yam tsis tas yuav tsum muaj superheat dhau heev.
Ua ib pas dej ua kua uas homogenizes hauv cov ntaiv.
Lub hauv paus: >95% ntawm fenb derives los ntawmPyrohopore ore[(Na, ca) ₂nb₂o₆ (Oh, f)].
Kev ua:AlleoticMic Txo:

3nb₂o₅ + 10 al {{+ 5 al₂o₃ + tshav kub (2,200 degree)
Tov nrog hlau oxide / FE SCRAP rau cov ntsiab lus hlau.
Yield 65-70% NB, qis dua cov ntsiab lus.
Fais arc rauv (EAF):
Txo ntawm pyrofore siab rau nrog ferrosilicon / carbon.
Qis dua qib (50-60% NB).
Cov neeg tsim khoom sab saum toj: CBMM (Brazil, 85% kev thoob thoob ntiaj teb), Magris cov khoom siv (Canada).
Vim li cas thiaj xaiv ferroniobium dua li lwm txoj hauv kev?
Ua tau zoo: 5-× Ntau lub zog ua ke qoob loo ntau dua Vanadium ib chav phaus hnyav.
Tus nqi: Tus pheej yig dua li ntshiab niobium (40-50 / kg vs.40-50 / Kgvs.150 / kg rau 99.9% NB).
Kev xyuas xim: Khoom FenB zam kev txaus ntshai ntawm niobium hmoov.
