🏗️ 1. Steel Micro-Alloying & High-Lub zog qis-Alloy (HSLA) Steel
Kwv yees li 85% ntawm ferro vanadium tso zis nkag rau hauv kev lag luam steel. Thaum ntxiv rau qhov ntau ntawm0.05% rau 0.20% Vrau hauv cov kua hlau, vanadium cov ntaub ntawv ruaj khov carbonitrides (VC, VN) thaum txias. Cov precipitates ua tiav ob lub hom phiaj metallurgical ib txhij: lawvpin austenite grain ciam teblos tsim finer ferrite nplej, thiab lawv muabnag lossis daus reinforcingnyob rau hauv lub ferrite theem nws tus kheej.
Qhov tshwm sim yog ib tsev neeg ntawmsiab-lub zog qis- alloy (HSLA) steelsuas xa 20-30% siab zog yield zog tshaj cov pa roj carbon monoxide dawb tsis muaj kev txi weldability lossis ductility. Suav txheemGB/T 1499.2-2018rau kub- dov ribbed tuav tam sim no lees paub HRB 600 qib, ib qib uas niaj hnub ua tiav ntawm vanadium micro-alloying. Los ntawm kev sib piv, cov laus HRB 335 qib tau raug tshem tawm ntawm tus qauv nkaus.
Tiag -Kev xa tawm thoob ntiaj teb yog qhov dav. Vanadium-cov kabmob rebar txhawb nqa cov skyscrapers, railway tunnels, ntev - ncua txuas hniav, thiab dams nyob rau hauv seismically active cheeb tsam. Korean thiab Japanese OEMs qhia qis-carbonFeV40–FeV50rau automotive chassis Cheebtsam, qhov twg qaug zog lub neej thiab nruj dimension tolerances yuav tsum tau. Hauv cov khoom siv roj thiab roj, vanadium- muaj zog linepipe steel ua tau raws li API 5L X80 cov kev cai thaum tuav Charpy toughness ntawm sub- xoom kub.
Ib qho hauv qab -koom kom zoo dua yog cov txheej txheem sib xws. Vanadium carbonitrides muaj ntau dua solubility tshaj niobium carbonitrides ntawm reheating kub, uas txhais tau hais tias V-cov kabmob steels tsis tshua muaj siab rau reheat rauv kub variation. Mills tshaj tawm cov khoom siv sib xws ntau ntau- rau- ntau, txo qis qis qis thiab cov neeg siv khoom thov.
⚙️ 2. Khoom Hlau & Tuag Hlau
Cov cuab yeej steel xav tau qhov siab tshaj plaws purity FeV qib vim tias cov pa roj carbon thiab sulfur residuals ncaj qha cuam tshuam rau hardenability, red hardness, thiab dimension stability thaum kho cua sov.FeV80-A, nrog cov pa roj carbon capped ntawm 0.15% thiab sulfur ntawm 0.04%, yog qib kev xaiv los tsimsiab - steel ceev (HSS)thiab txias- ua haujlwm tuag steels xws li AISI M2, M35, D2, thiab A2.
Hauv cov alloys no, cov ntsiab lus vanadium tuaj yeem ncav cuag 1% txog 5%. Lub vanadium ua cov ntaub ntawv nyuaj heev MC- hom carbides uas tiv taus softening ntawm siab txiav kub thiab txhim kho hnav tsis kam tiv thaiv cov khoom ua haujlwm abrasive. Ib daim ntawv qhia HSS raug hu rau 1.8–2.2% V; ntawm cov qib no, siv FeV50 yuav qhia ntau dhau nrog cov hlau thiab carbon, diluting lub alloy tsim. FeV80-A daws qhov no los ntawm kev xa cov vanadium ntau dua ib kilogram nrog cov kab mob tsawg.
Cov cuab yeej tuag casting sawv cev rau lwm qhov siab - ntu nqi. Kub- ua haujlwm tuag hlau zoo li H13 (AISI) vam khom nruab nrab vanadium (0.8–1.2%) los tiv thaiv thermal qaug zog tawg thaum rov ua cua sov thiab cua txias. Cov cuab yeej Japanese thiab German- cov neeg tsim khoom siv hlau feem ntau cog lus rau FeV80-A nrog kev txwv ntxiv ntawm txhuas thiab phosphorus dhau ntawm GB / T 4139-2012 lub rooj, uas cuam tshuam txog cov kev cai ntawm cov khoom siv zoo tshaj plaws steel.
✈️ 3. Titanium Alloys rau Aerospace
Txawm hais tias ferro vanadium tsis ntxiv ncaj qha rau molten titanium (lub reactivity ntawm titanium nrog hlau yuav muaj teeb meem),fwv 80ua hauj lwm raws li ib tug tseem ceeb master alloy precursor nyob rau hauv zus tau tej cov titanium -vanadium alloys. Tus piv txwv nto moo tshaj plaws yogTi-6Al-4V, uas suav rau ntau tshaj li ib nrab ntawm tag nrho cov titanium alloy tso zis nyob rau hauv lub tebchaws United States thiab dominates aerospace structural applications.
Hauv cov saw hlau no, siab -purity FeV80 yog thawj zaug hloov mus rau vanadium hlau los yog vanadium- aluminium master alloy los ntawm kev txo cov tshuaj los yog cov txheej txheem electrolytic. Lub vanadium ces nkag mus rau titanium yaj ntawm aluminothermic los yog electron-beam txias-heart remelting txoj kev. Lub vanadium stabilizes theem beta hauv titanium, txhim kho chav -kub lub zog, qaug zog tawg tsis kam, thiab forgeability piv rau unalloyed titanium.
Tshaj li Ti-6Al-4V, aerospace daim ntawv thov txuas mus rauTi-6Al-6V-2SnthiabTi-8Al-1V-Mo, qhov twg vanadium pab txhawb cov khoom muaj zog- kev daws teeb meem ntxiv dag zog thiab nkag siab ntawm qhov kub nruab nrab. Rocket motor case, compressor discs, landing gear forgings, and airframe brackets tag nrho lawv cov ntsiab lus vanadium rov qab mus rau ferro vanadium uas ua rau hluav taws xob -arc lossis aluminothermic furnaces.
🧪 4. Chemical Catalysts & Industrial Chemicals
Vanadium ntau lub xeev oxidation (+2 rau +5) ua rau nws yog ib qho tshwj xeeb catalyst rau oxidation cov tshuaj tiv thaiv. Thaum kawg catalyst yog feem ntauVanadium pentoxide (V₂O₅), ferro vanadium-tshwj xeeb tshaj yog siab-vanadium FeV80-ua raws li cov ntsiab lus vanadium nyob rau hauv cov khoom ua ntej. Cov neeg tsim khoom siv tshuaj yuav FeV thiab hloov nws mus rau ammonium metavanadate lossis V₂O₅ flakes ntawm hydrometallurgical ua.
Kev siv tshuaj lom neeg loj tshaj plaws yog qhovtiv tauj txheej txheem rau kev tsim cov sulfuric acid. Txhawb V₂O₅ catalysts ntawm silica lossis diatomite ua haujlwm ntawm 400-600 degree, oxidizing sulfur dioxide rau sulfur trioxide nrog kev xaiv ntau tshaj 98%. Ntiaj teb no sulfuric acid ntau tshaj 250 lab tonnes txhua xyoo; Ib feem tseem ceeb ntawm vanadium catalyst cov lus nug yog thaum kawg tau los ntawm ferro vanadium feedstock.
Lwm qhov hluav taws xob tseem ceeb yogtxiv neej anhydride ntau lawm, qhov twg vanadium -phosphorus oxide (VPO) catalysts oxidize butane rau txiv neej anhydride. Cov tshuaj nruab nrab no pub cov khoom siv tsis zoo polyester resins, tshuaj ua liaj ua teb, thiab zaub mov acidulants. Ferro vanadium cov neeg tsim khoom uas ua haujlwm rau cov neeg siv khoom siv tshuaj lom neeg feem ntau txwv nruj dua cov sulfur thiab phosphorus ntau dua li tus qauv GB / T 4139-2012 qab nthab, vim tias cov impurities tshuaj lom hauv qab catalyst formulations.
🔩 5. Kev Siv Khoom Siv Ntxiv
