Lub hauv paus ntsiab lus thiab kev ua haujlwm ntawm Vanadium yog dab tsi-Kev tshem tawm Refining Rau Gr5 Titanium Alloy Tubes?

Gr5 (Ti‑6Al-4V) titanium alloyboasts cov khoom zoo tshaj plaws thiab ua haujlwm raws li lub hauv paus tube substrate rau high-end khoom sectors. Raws li cov khoom siv alloying, vanadium tuaj yeem ua kom zoo dua cov khoom siv. Txawm li cas los xij, dawb vanadium thiab vanadide impurities zoo li tsim thaum lub sij hawm smelting, uas degrade qhov kev ua tau zoo ntawm cov hlab. Yog li ntawd, high-efficiency vanadium-tshem tawm refining yog ib qho tseem ceeb los lav lub raj zoo.

 

 

Gr5 titanium alloy tubes yog tsim los siv crude titanium tetrachloride li raw khoom ntawm chlorination, refining, txo, forging thiab dov. Vanadium impurities feem ntau muaj nyob rau hauv cov ntaub ntawv ntawm VOCl₃ thiab VCl₄, los ntawm crude titanium tetrachloride.

 

Qhov sib txawv ntawm qhov sib txawv ntawm vanadium impurities thiab TiCl₄ tsuas yog nyob ib ncig ntawm 10 degree, nrog kev sib cais coefficient ntawm 1.22. Pa rectification tsis tuaj yeem ua tiav lawv cov kev sib cais, yog li kev hloov kho tshuaj lom neeg tau siv dav hauv kev lag luam rau kev tshem tawm vanadium.

 

1. Txheej txheem txheej txheem

Txo cov neeg ua hauj lwm, cov neeg ua hauj lwm nyuaj los yog cov dej nag tau ntxiv los hloov cov vanadium high-valent mus rau qhov tsis zoo-soluble high-boiling-point vanadium precipitates. TiCl₄ ces purified los ntawm solid-kua sib cais los tswj impurities ntawm qhov chaw.

 

2. Lub Hom Phiaj Txheej Txheem

The objective is not to strip vanadium completely, but to retain chemically‑bonded vanadium required for the alloy and stabilize total vanadium content within 3.5%‑4.5%. Kev phom sij tsis muaj vanadium thiab vanadides yuav tsum raug tshem tawm kom tsis txhob muaj lub raj tawg nrog rau kev ua kom tsis zoo ntawm lub zog thiab corrosion kuj tshwm sim los ntawm impurity segregation.

 

 

1. Copper Wire Vanadium Tshem Tawm

Cov txheej txheem kev kho mob zoo ib txwm siv tau rau cov me me-batch high-end Gr5 titanium raj. Ntawm 80-120 degree, tooj liab xov hlau txo VOCl₃ thiab VCl₄ los tsim vanadium precipitates, thiab impurities raug tshem tawm los ntawm cov kua-kua sib cais.

2. Mineral Roj Vanadium Tshem Tawm

Mainstream industrialized txheej txheem haum rau loj-scale nruam ntau lawm. Lub teeb ntxhia roj yog ntxiv rau ntawm 90-110℃kom txo tau qhov siab-valent vanadium thiab ib txhij tshem tawm ntau yam hlau tsis huv, ua raws li kev ua kom huv los ntawm kev kho thiab pom.

Qhov zoo: Cov khoom siv tsis tshua muaj nqi, muaj peev xwm ntau lawm, muaj peev xwm loj thiab tus nqi qis.

Qhov tsis zoo: Cov kev cai nruj rau kev tswj xyuas qhov ntsuas; txaus ntshai ntawm cov roj residue, scaling thiab cov yeeb nkab thaiv; dav siv los ntawm cov tuam txhab loj thiab nruab nrab hauv tsev titanium.

 

3. Hydrogen Sulfide Vanadium Tshem Tawm

Gas-theem txo cov txheej txheem siv rau nruab nrab-rau-qib-qib titanium raw khoom thiab cov hlab. H₂S yog qhia ntawm 80-100℃kom precipitate vanadium thiab ib nrab hlau impurities.

Qhov zoo: Kev ua haujlwm yooj yim, ceev cov tshuaj tiv thaiv, cov cuab yeej siv qis.

Disadvantages: Cov tshuaj lom thiab corrosive H₂S, siab tiv thaiv ib puag ncig; poob ntawm titanium raw cov ntaub ntawv, mediocre tiav-cov khoom ua tau zoo; tau maj mam phased tawm hauv high-end teb.

 

4. Fatty Acid Vanadium Tshem Tawm

Novel ntsuab complexation-txo cov txheej txheem. Unsaturated fatty acids muab ntau dua vanadium-tshem tawm haujlwm. High-valent vanadium yog hloov mus ua tsis zoo-soluble vanadium complex precipitates.

Qhov zoo: Cov pa phem tsawg, tsis muaj cov khoom muaj kuab lom, cov khoom siv rov ua dua tshiab, kev ua haujlwm zoo ntawm vanadium-tshem tawm.

Disadvantages: Tsis paub tab technology, kim reagents, rhiab tshuaj tiv thaiv tej yam kev mob, nyiam ntawm caking; tseem nyob rau theem ntawm kev sim kev lag luam.
