Aluminium alloy rau foob pob hluav taws roj tank
Cov ntaub ntawv tsim nyog muaj feem xyuam nrog ntau yam teeb meem xws li foob pob hluav taws lub cev qauv tsim, tsim thiab ua cov cuab yeej siv, kev npaj cov khoom siv, thiab kev lag luam, thiab yog tus yuam sij rau kev txiav txim siab lub foob pob hluav taws qhov zoo thiab lub peev xwm them nyiaj.Raws li cov txheej txheem kev txhim kho ntawm cov khoom siv, cov txheej txheem kev loj hlob ntawm cov khoom siv foob pob hluav taws tuaj yeem muab faib ua plaub tiam.Thawj tiam yog 5-series aluminium alloys, uas yog, Al-Mg alloys.Cov neeg sawv cev alloys yog 5A06 thiab 5A03 alloys.Lawv tau siv los tsim P-2 foob pob hluav taws roj tank cov qauv hauv 1950s lig thiab tseem siv niaj hnub no.5A06 alloys muaj 5.8% Mg rau 6.8% Mg, 5A03 yog Al-Mg-Mn-Si alloy.Qhov thib ob tiam yog Al-Cu-raws li 2-series alloys.Lub tank tso tsheb hlau luam ntawm Tuam Tshoj lub Peb Hlis Ntuj ntev ntawm cov tsheb tsim tawm yog ua los ntawm 2A14 alloys, uas yog Al-Cu-Mg-Mn-Si alloy.Txij xyoo 1970 mus txog rau tam sim no, Tuam Tshoj pib siv 2219 alloy manufacturing tank, uas yog Al-Cu-Mn-V-Zr-Ti alloy, yog siv dav hauv kev tsim khoom ntawm ntau lub tsheb tso tsheb hlau luam.Nyob rau tib lub sijhawm, nws kuj tau siv dav hauv cov qauv ntawm riam phom tua hluav taws kub qis, uas yog cov hlau uas muaj qhov kub thiab txias thiab kev ua haujlwm zoo.
Aluminium alloy rau cabin qauv
Txij li thaum txoj kev loj hlob ntawm kev tsim tsheb nyob rau hauv Tuam Tshoj nyob rau hauv lub xyoo 1960 mus txog rau tam sim no, aluminium alloys rau lub alarm qauv ntawm lub launching tsheb yog dominated los ntawm thawj tiam thiab lub thib ob tiam alloys sawv cev los ntawm 2A12 thiab 7A09, thaum txawv teb chaws lub teb chaws tau nkag mus rau lub thib plaub tiam. Cabin structural aluminium alloys (7055 alloy thiab 7085 alloy), lawv tau siv dav vim lawv lub zog muaj zog, tsis tshua muaj quenching rhiab heev thiab rhiab heev.7055 yog Al-Zn-Mg-Cu-Zr alloy, thiab 7085 kuj yog Al-Zn-Mg-Cu-Zr alloy, tab sis nws cov impurity Fe thiab Si cov ntsiab lus tsawg heev, thiab Zn ntsiab lus siab ntawm 7.0% ~ 8.0%.Qhov thib peb tiam Al-Li alloys sawv cev los ntawm 2A97, 1460, thiab lwm yam. tau siv nyob rau hauv txawv teb chaws aerospace industries vim lawv siab zog, siab modulus, thiab siab elongation.
Particle-reinforced aluminium matrix composites muaj qhov zoo ntawm qhov siab modulus thiab siab zog, thiab tuaj yeem siv los hloov 7A09 alloys los tsim cov khoom siv semi-monocoque cabin stringers.Lub koom haum ntawm Kev Tshawb Fawb Hlau, Suav Academy ntawm Kev Tshawb Fawb, Harbin Institute of Technology, Shanghai Jiaotong University, thiab lwm yam tau ua haujlwm ntau hauv kev tshawb fawb thiab kev npaj cov particle-reinforced aluminium matrix composites, nrog kev ua tiav zoo kawg.
Al-Li alloys siv nyob rau hauv txawv teb chaws aerospace
Daim ntawv thov kev vam meej tshaj plaws ntawm lub tsheb aerospace txawv teb chaws yog Weldalite Al-Li alloy tsim los ntawm Constellium thiab Quebec RDC, suav nrog 2195, 2196, 2098, 2198, thiab 2050 Alloy.2195 alloy: Al-4.0Cu-1.0Li-0.4Mg-0.4Ag-0.1Zr, uas yog thawj Al-Li alloy tau ua tiav kev lag luam rau kev tsim cov roj tso tsheb hlau luam uas tsis kub kub rau foob pob hluav taws.2196 alloy: Al-2.8Cu-1.6Li-0.4Mg-0.4Ag-0.1Zr, tsawg ntom, siab zog, siab tawg toughness, Ameslikas tsim rau Hubble hnub ci vaj huam sib luag ncej profiles, tam sim no feem ntau yog siv rau extruding aircraft profiles.2098 alloy: Al-3.5 Cu-1.1Li-0.4Mg-0.4Ag-0.1Zr, Ameslikas tsim rau kev tsim khoom ntawm HSCT fuselage, vim nws lub zog qaug zog, nws yog tam sim no siv nyob rau hauv F16 fighter fuselage thiab spacecraft Falcon tso roj tank .2198 alloy: Al-3.2Cu-0.9Li-0.4Mg-0.4Ag-0.1Zr, siv rau dov daim ntawv lag luam dav hlau.2050 alloy: Al-3.5Cu-1.0Li-0.4Mg- 0.4Ag-0.4Mn-0.1Zr, siv los tsim cov phaj tuab los hloov 7050-T7451 alloy tuab daim hlau rau kev tsim cov khoom lag luam dav hlau lossis foob pob ua ntxaij launching Cheebtsam.Piv nrog rau 2195 alloy, Cu + Mn cov ntsiab lus ntawm 2050 alloy yog qhov tsawg los txo qhov quenching rhiab heev thiab tswj cov khoom siv siab ntawm cov phaj tuab, lub zog tshwj xeeb yog 4% siab dua, qhov tshwj xeeb modulus yog 9% siab dua, thiab cov pob txha toughness yog nce nrog kev nyuaj siab corrosion cracking kuj thiab siab qaug zog tawg kev loj hlob kuj, nrog rau kub stability.
Tuam Tshoj txoj kev tshawb fawb ntawm forging rings siv nyob rau hauv foob pob ua ntxaij qauv
Tuam Tshoj lub chaw tsim khoom tsim tsheb yog nyob rau hauv Tianjin Economic thiab Technological Development Zone.Nws yog tsim los ntawm kev tshawb fawb foob pob hluav taws thiab thaj chaw tsim khoom, thaj chaw siv thev naus laus zis thev naus laus zis kev lag luam thiab thaj chaw txhawb nqa.Nws integrates foob pob ua ntxaij qhov chaw tsim khoom, cov khoom sib dhos, kev sib dhos zaum kawg.
Lub foob pob hluav taws tso cia tank yog tsim los ntawm kev sib txuas cov thooj voos kheej kheej nrog qhov ntev ntawm 2m mus rau 5m.Lub tso tsheb hlau luam yog ua los ntawm txhuas alloy, yog li lawv yuav tsum tau txuas thiab ntxiv dag zog rau aluminium alloy forging rings.Tsis tas li ntawd, cov khoom sib txuas, cov nplhaib hloov pauv, hloov cov thav duab thiab lwm qhov chaw ntawm lub dav hlau xws li tso tsheb thiab chaw nres tsheb kuj yuav tsum tau siv cov hlua sib txuas, yog li forging rings yog ib qho tseem ceeb heev ntawm kev sib txuas thiab cov khoom siv.Southwest Aluminium (Group) Co., Ltd., Northeast Light Alloy Co., Ltd., thiab Northwest Aluminium Co., Ltd. tau ua haujlwm ntau hauv kev tshawb fawb thiab kev tsim kho, tsim thiab ua cov nplhaib forging.
Nyob rau hauv 2007, Southwest Aluminium kov yeej kev teeb meem xws li loj-scale casting, forging billet qhib, nplhaib dov, thiab txias deformation, thiab tsim ib tug aluminium alloy forging nplhaib nrog ib txoj kab uas hla ntawm 5m.Cov tub ntxhais tseem ceeb forging thev naus laus zis tau ua tiav qhov sib txawv hauv tsev thiab tau ua tiav rau Lub Peb Hlis Ntuj-5B.Nyob rau hauv 2015, Southwest Aluminium tau tsim thawj super-loj aluminium alloy tag nrho forging nplhaib nrog ib txoj kab uas hla ntawm 9m, teeb tsa lub ntiaj teb cov ntaub ntawv.Nyob rau hauv 2016, Southwest Aluminium tau ntse kov yeej ib tug xov tooj ntawm cov tseem ceeb technologies xws li dov txoj kev thiab kev kho cua sov, thiab tsim ib tug super-loj aluminium alloy forging nplhaib nrog ib txoj kab uas hla ntawm 10m, uas teem ib tug tshiab ntiaj teb no cov ntaub ntawv thiab daws tau ib tug tseem ceeb kev teeb meem. rau txoj kev loj hlob ntawm Tuam Tshoj lub heavy-duty launch tsheb.
