Aluminiyamu aloyi ali ndi makhalidwe kulemera kuwala, mphamvu mkulu, kukana dzimbiri ndi kukonza mosavuta.Aluminiyamu aloyi ntchito m'munda ndege nthawi zambiri amatchedwa aviation zotayidwa aloyi.Lili ndi mndandanda wa ubwino monga mphamvu yapamwamba, kukonza bwino ndi mawonekedwe, mtengo wotsika komanso kusungika bwino, ndipo amagwiritsidwa ntchito kwambiri muzopangidwe kake ka ndege. Kuthamanga kwa ndege, kuchepetsa kulemera kwapangidwe ndi kubisala, mphamvu zenizeni, kuuma kwapadera, kulekerera kuwonongeka, mtengo wopangira ndi kuphatikizika kwa aloyi ya aluminiyamu kumalimbikitsidwa kwambiri. , luso processing zinthu monga anagubuduza, extrusion, forging ndi kutentha mankhwala, kupanga ndi processing wa mbali zotayidwa aloyi, ndi khalidwe ndi kusintha ntchito ntchito dongosolo dongosolo chuma.
1. Aluminium alloy kapangidwe
Mfundo yofunika kwambiri ya ultra-high mphamvu zotayidwa aloyi ndi kukhathamiritsa kamangidwe ka aloyi zikuchokera, kusintha zimene zili aloyi zinthu ndi kuchepetsa zonyansa.Ndikofunikira kulimbikitsa kafukufuku limagwirira ntchito osowa lapansi ndi kufufuza zinthu zina mu aloyi aloyi. , ndi kupititsa patsogolo mphamvu, kulimba ndi dzimbiri kukana aloyi potengera limagwirira Mipikisano mpweya kulimbitsa gawo opangidwa ndi Mipikisano alloying.05, 2018 nkhani ya nonferrous zitsulo zopulumutsa mphamvu lofalitsidwa “a aluminothermic kuchepetsa njira yokonzekera zotayidwa - scandium wapakatikati aloyi, kufufuza scandium ndi anawonjezera mu zotayidwa aloyi (0.15 wt % ~ 0.25 wt %), akhoza kwambiri kusintha mphamvu ya aloyi zotayidwa, kwambiri kusintha ozizira ndi otentha Machining, kukana dzimbiri, ndi kukonzekera latsopano Kupanga zinthu zakuthambo, zamagetsi ndi madera ena okhala ndi zida zatsopano. Pulojekitiyi imatenga scandium oxide yotengedwa m'madzi onyansa a titanium dioxide nditungsten slag ngati zopangira, zotayidwa ingot monga kuchepetsa wothandizila, ndi flux wapadera, kuchepetsa aluminothermic pansi pa chikhalidwe non-vacuum, kupyolera kutentha kutchinjiriza kuponyera ndi pamwamba mankhwala kupanga apamwamba aluminium-scandium master alloy.Kupyolera mu kafukufuku pa zosungunulira dongosolo, pulojekitiyi imathandizira njira zamakono, zimachepetsa zofunikira pa chiyero cha scandium oxide ya zopangira, ndi kuchepetsa mtengo.
2. Aluminium alloy processing
Kupititsa patsogolo luso lamakono lazitsulo lachitsulo (monga kutsika kwafupipafupi kwa electromagnetic semi-continuous casting), kupanga ndi kupititsa patsogolo luso lamakono la kupanga ndege, kupeza mapangidwe apamwamba a ingot ndikuwongolera zinthu zonse za alloy kupyolera mu kusintha. Njira yokonzekera ndi kusankha koyenera kwa magawo aukadaulo; Njira yatsopano komanso yabwinoko yochizira kutentha idapangidwa kuti ipeze zinthu zonse za aluminiyamu aloyi, ndikukwaniritsa mgwirizano wamphamvu kwambiri, kulimba kwapamwamba, kulimba kwambiri komanso kukana kwa dzimbiri. China University of Water Resources and Electric Power yachita kafukufuku wokhudza kugwiritsa ntchito ukadaulo wa vacuum brazing mu zida zachitsulo zotha kupirira zotayidwa ndi aluminiyamu.Kuwotcherera kwa zitsulo zopangira zitsulo zotayidwa ndi aluminiyamu zowonongeka ndi mtundu watsopano wa teknoloji yowotcherera yomwe ili ndi zofunikira zaumisiri wapamwamba ndi kusankha zinthu. Chifukwa imagwiritsidwa ntchito kwambiri muzamlengalenga, ndondomeko iliyonse yaukadauloyi sayenera kunyalanyazidwa.Mu masterbatch asanu monga experimental chinthu, kupambana ndi inferiority kusanthula 5 mitundu ya masterbatch zipangizo motero, pansi pa chikhalidwe vakuyumu kuwotcherera kutentha mankhwala a zotayidwa aloyi zitsulo kusankha zinthu mu ntchito zothandiza zinthu zoyenera ndi yoyenera mikhalidwe experimental ntchito, chifukwa pansi zingalowe mu zinthu zingalowe mu ntchito zothandiza kuwotcherera kutentha mankhwala a aluminiyumu aloyi chuma zimakupiza, henan zotayidwa makampani co., LTD zida zotayidwa aloyi mbale conductivity pa intaneti kuzindikira, malinga ndi AMS zofunika muyezo, conductivity kuzindikira ndi mbali yofunika ya mbale zotayidwa aloyi. amagwiritsidwa ntchito m'makiyi amakampani opanga ndegek, kukhazikitsa pa intaneti kudziwika kwa aluminiyamu aloyi ndege madutsidwe mbale madutsidwe, moganizira zazamlengalenga aluminiyamu kasamalidwe pepala akukumana ndi zenizeni ndi mwamsanga mavuto kasamalidwe.
3, Aluminium alloy kapangidwe
Limagwirira wa mphamvu ndi kulimba, dzimbiri nkhawa ndi kutopa dzimbiri kwa kopitilira muyeso-mkulu mphamvu zotayidwa aloyi anaphunziridwa mozama.Develop latsopano akamaumba teknoloji.Pakati pawo, ukalamba akamaumba luso Chili kukalamba Buku ndi Machining, amene sangathe kusintha ntchito ya aluminium alloy komanso amachepetsa mtengo wopanga ndege.Ili ndi chiyembekezo chogwiritsa ntchito popanga zida zopindika pamtunda, ndipo ndi kafukufuku yemwe akuyang'ana kwambiri kunyumba ndi kunja. Capital Aerospace Machinery Co., Ltd. kwa Azamlengalenga kuwala zitsulo zipangizo.Iwo amakhulupirira kuti poyerekeza ndi zitsulo zina 3D umisiri kusindikiza, arc fuseji zowonjezera kupanga ali ndi makhalidwe a mtengo otsika kupanga ndi mkulu kupanga dzuwa, amene amapereka mwayi kuthetsa vutoli.The kafukufuku udindo wa arc fuse zoonjezera kupanga luso zipangizo kuwala zitsulo zipangizo monga monga aluminium alloy ndi titaniyamu aloyi kunyumba ndi kunja akuwunikiridwa.Mavuto akulu ndi njira zachitukuko zikuwonetsedwa. Pomaliza, chitukuko chaukadaulo wamba wamba monga kupsinjika ndi kuwongolera mawonekedwe, mapulogalamu okonzekera njira, kuyang'anira pa intaneti ndi kuwongolera mayankho akupanga njira yopangira zida zazikulu za arc fuse. analyzed.Chinalco kum'mwera chakumadzulo zotayidwa gulu (zochepa) udindo kampani anagubuduza chomera cha pretensioning pa zotayidwa aloyi quenching mapindikidwe wa mbale kuwongola kayeseleledwe anali kusanthula, ndi zotayidwa aloyi wandiweyani mbale amene ankagwiritsa ntchito m'munda wa zakuthambo, n'zosavuta kukhala katundu wolemera. mbale Kugubuduza pambuyo quenching mavuto mapindikidwe, mwachindunji zimakhudza lonse la wandiweyani mbale zokolola, mtundu wa ulamuliro Baibulo ndi luso kuwongola amawunikidwa, kuthetsa bwino vuto la mapindikidwe a zotayidwa aloyi wandiweyani mbale, zotayidwa aloyi wandiweyani mbale palokha mtengo wabwino ndi ntchito. College of Materials Science ndi Engineering, Hebei University of Science ndiTechnology waphunzira anataya nkhungu kuponyera luso la zotayidwa aloyi, amene wakhala "teknoloji yatsopano kuponyera m'zaka za zana la 21" chifukwa cha ubwino wabwino zachuma ndi katundu wabwino wa castings.The chitukuko cha makampani amalimbikitsa chitukuko cha zotayidwa aloyi anataya nkhungu kuponyera. luso ndi kupangitsa kukhala mbali yofunika ya kuponya luso development.This pepala makamaka imayambitsa kafukufuku udindo ndi ntchito udindo wa zitsulo zotayidwa aloyi anataya nkhungu kuponyera luso mu mbali ya zipangizo maonekedwe, ❖ kuyanika luso, kupanga luso ndi kayeseleledwe manambala, etc., ndi amayembekezera izo.
4.Chiyembekezo
Kukula kwa aluminiyamu aloyi ndi mphamvu mkulu ndi kulimbikira mkulu ndi chitukuko makamaka pa kuukitsa mphamvu zakuthupi, plasticity, toughness, kukana dzimbiri ndi kukana kutopa ndi zina zotero ntchito mabuku kupanga kafukufuku, aloyi ake atsopano angathe mwa kusintha aloyi zikuchokera, kutengera zinthu zatsopano alloying, njira monga kutengera processing watsopano ndi kupanga luso chitukuko, koma ntchito kafukufuku akadali yotopetsa yaitali.Research ndi chitukuko ayenera kulabadira mfundo ziwiri: choyamba, aloyi watsopano si zikuchokera aloyi, koma ziyenera kuphatikizapo aloyi zikuchokera, processing luso ndi ntchito, atatu okha ophatikizana kukhala zabwino aloyi zakuthupi; Chachiwiri, chitukuko cha zipangizo aloyi latsopano sangathe kukhala mu labotale, chofunika kwambiri ndi kuchita kupanga misa pansi. Mwachidule, ndi kuzama kwa kafukufuku pa Ultra-high mphamvu zotayidwa aloyi., padzakhala ukadaulo wamankhwala wosungunula wangwiro komanso njira yochizira kutentha, ukadaulo wapamwamba kwambiri wowumba komanso mawonekedwe amtundu wa aluminiyamu wamphamvu kwambiri, motero kulimbikitsa kugwiritsa ntchito aloyi ya aluminiyamu yamphamvu kwambiri muzamlengalenga.
