Koj puas paub lub tshuab forging ntawm titanium alloy?
Titanium alloys muaj cov khoom zoo xws li lub zog siab, zoo corrosion kuj, tsis muaj hlau nplaum, thiab kev ua haujlwm vuam zoo, nrog rau cov khoom zoo xws li superconductivity, hydrogen cia, thiab nco. Titanium alloys tau siv dav hauv qee qhov kev txiav txim siab xws li aerospace, kev lag luam tub rog, kev tsim kho dej hiav txwv thiab kev lag luam petrochemical.
Nyob rau hauv daim ntawv thov ntawm ntau yam titanium alloy khoom,Qib 5 Titanium Forgingfeem ntau yog siv nyob rau hauv lub sij hawm uas yuav tsum tau muaj zog, siab toughness thiab siab ntseeg, xws li roj turbine compressor discs thiab kho mob pob txha. Yog li ntawd, tsis tsuas yog qhov siab qhov tseeb yog qhov yuav tsum tau ua rau forgings, tab sis kuj tseem muaj cov khoom siv nrog cov yam ntxwv zoo thiab kev ruaj ntseg siab.
Daim ntawv thov ib nrab ntawm Qib 5 Titanium Forging
1. Aerospace teb
50% ntawm titanium cov ntaub ntawv nyob rau hauv lub ntiaj teb no yog siv nyob rau hauv lub aerospace teb. 30% ntawm lub cev ntawm cov tub rog aircraft siv titanium alloy, thiab tus nqi ntawm titanium siv nyob rau hauv civil aircraft yog maj mam nce. Raws li cov lus ceeb toom, tus nqi ntawm titanium siv hauv Boeing 787 tau mus txog ntau dua 15%, thiab tus neeg sawv cev ntawm titanium alloy siv nyob rau hauv airframe yog Ti-6Al-4V alloy, uas muaj kev nyab xeeb tshaj plaws. . Nyob rau hauv lub tshav pob ntawm aerospace, titanium alloy forgings yog siv nyob rau hauv roj tso tsheb hlau luam ntawm foob pob ua ntxaij thiab satellite propulsion xyaw, hniav ntawm cov kua roj turbo twj tso kua mis thiab inlet seem ntawm cov twj tso kua mis.
2. Chav turbine hniav rau kev tsim hluav taws xob
Ua kom ntev ntawm cov hniav ntawm chav turbines rau thermal zog tsim yog ib qho kev ntsuas zoo los txhim kho lub zog tsim hluav taws xob, tab sis lengthening cov hniav yuav ua rau kom cov load ntawm lub rotor [i]. Kev siv cov titanium alloy forgings raws li cov hniav tuaj yeem txo cov load, thiab kev siv 1m ntev Ti-6Al-4V alloy hniav tom kawg ntawm high-speed rotating chav turbines tau siv nyob rau hauv 1991.
Forging Technology ntawm Titanium Alloy
Nyob rau hauv thermal ua ntawm titanium alloys, cov cua kub kub yog qhov tseem ceeb heev. Thaum qhov kub thiab txias qis, qhov deformation tsis kam yog ntau dua, thiab nws yooj yim los tsim cov kab nrib pleb thiab lwm yam tsis xws luag. Nyob rau tib lub sijhawm, nws kuj tseem muaj kev vam khom rau qhov deformation ceev thaum ua haujlwm thermal. Sib npaug los yog siab dua, tuaj yeem txo qis hauv forging kub thaum lub sij hawm forging.
1. Forging tshuab ntawm cav discs
Forging thev naus laus zis ntawm cav discs Cov discs siv nyob rau hauv aircraft engine xav tau siab qaug zog thiab tawg toughness. Ti-6Al-2Sn-4Zr-6Mo alloy plated qhov chaw yog siv nyob rau hauv 700K nruab nrab kub cheeb tsam. Cov txheej txheem kev ua ib txwm yog forging nyob rau hauv - cheeb tsam, thiab nws cov qauv yog theem thiab equiaxed nplej thiab nplua acicular ob-theem qauv, thiab cov pob txha toughness tus nqi yog tsawg. Txhawm rau txhim kho qhov taw tes no, ib txoj kev forging rhuab hauv cheeb tsam tau tsim.
Txoj kev forging yog cua sov forging saum toj no theem hloov kub, uas yuav ua rau recrystallization, yog li qhov kub thiab txias deformation muaj feem xyuam rau cov khoom siv, thiab reheating thaum lub sij hawm forging yog tsis tso cai kom tsis txhob deformation. Yog li ntawd, forging kub thiab deformation yuav tsum nruj me ntsis tswj nyob rau hauv forging. Rau Ti-6Al-2Sn-4Zr-Mo alloy, kev ua haujlwm kub yog nyob rau hauv thaj tsam ntawm 1073 ~ 1323K, thiab yuav tsum muaj kev ua haujlwm txaus deformation. Cov qauv forging yog tag nrho cov koob-zoo li tus, thiab tus nqi tawg toughness yog txhim kho.
2. Turbine hniav forging tshuab
Turbine hniav yog nyias, thiab qhov kub thiab txias poob sai heev thaum lub sij hawm forging txheej txheem, yog li cov pwm yuav tsum tau precisely tsim. Tam sim no, ib lub tshuab tau tsim los siv lub zog ntawm kev nce thiab nqis los ua kom zoo li cov hniav nto.
3. Nplhaib tsim tshuab
Lub cav kiv cua casing thiab compressor casing tag nrho siv Ti-6Al-4V alloy dov txuas. Rau cov khoom siv titanium alloy nrog cov khoom siv siab heev, txo cov khoom nkag ntawm cov khoom siv tau zoo heev rau kev txo nqi. Feem ntau, qhov ze-huv thev naus laus zis (yog hais txog kev tsim tshuab uas tuaj yeem siv los ua cov khoom siv tshuab tom qab ib feem tau tsim, tsuas yog ib qho me me ntawm kev ua haujlwm lossis tsis tas yuav tsum tau ua), siv cov thev naus laus zis no, cov ntaub ntawv yuav tsum tau ua. raug txo los ntawm ntau tshaj 55%.
Thaum ua cov nplhaib tuab, txhawm rau kom tsis txhob muaj cov kab nrib pleb, nws yog ib qho tsim nyog yuav tsum muab lub zog compaction ntau npaum li qhov ua tau, thiab yuav tsum tau them nyiaj rau kev tswj cov qauv thiab qhov kub thiab txias ntawm lub nplhaib thaum ua haujlwm. Nyob rau hauv luv luv, zus tau tej cov titanium alloy forgings yuav tsum tau ua kom zoo kub thiab deformation kom tau zoo forgings.
Vim li no, hauv kev tsim cov txheej txheem ntawm Qib 5 Titanium Forging, cov yam ntxwv ntawm titanium alloy yuav tsum tau siv tag nrho. Txhawm rau kom tau txais cov khoom zoo zoo, forging kub thiab yas deformation yuav tsum tau tswj kom zoo thaum lub sijhawm tsim khoom.
