Aluminiyamu aloyi kwa rocket mafuta thanki
Zipangizo zamapangidwe zimagwirizana kwambiri ndi zinthu zingapo monga kapangidwe ka rocket body, kupanga ndi kukonza ukadaulo, ukadaulo wokonzekera zinthu, komanso chuma, ndipo ndiye chinsinsi chodziwikiratu momwe rocket imanyamuka komanso kuchuluka kwa malipiro. Malinga ndi chitukuko cha dongosolo la zinthu, njira yopangira zida za rocket mafuta amatha kugawidwa m'mibadwo inayi. M'badwo woyamba ndi 5-series aluminium alloys, ndiko kuti, Al-Mg alloys. Ma aloyi oyimira ndi 5A06 ndi 5A03 aloyi. Anagwiritsidwa ntchito popanga P-2 rocket tank tank mafuta kumapeto kwa zaka za m'ma 1950 ndipo akugwiritsidwabe ntchito mpaka pano. Ma 5A06 aloyi okhala ndi 5.8% Mg mpaka 6.8% Mg, 5A03 ndi aloyi ya Al-Mg-Mn-Si. M'badwo wachiwiri ndi Al-Cu-based 2-series alloys. Matanki osungiramo magalimoto oyambira aku China a Long March amapangidwa ndi ma aloyi a 2A14, omwe ndi aloyi ya Al-Cu-Mg-Mn-Si. kuyambira m'ma 1970 mpaka pano, China anayamba kugwiritsa ntchito 2219 aloyi kupanga aloyi thanki yosungirako, amene ndi aloyi Al-Cu-Mn-V-Zr-Ti, chimagwiritsidwa ntchito popanga akasinja osiyanasiyana Launch yosungirako galimoto. Nthawi yomweyo, imagwiritsidwanso ntchito kwambiri popanga zida zoyambira kutentha kwamafuta otsika, omwe ndi aloyi yokhala ndi magwiridwe antchito otsika kwambiri komanso magwiridwe antchito athunthu.
Aluminiyamu alloy kwa kanyumba kamangidwe
Kuyambira kukula kwa magalimoto Launch ku China m'ma 1960 mpaka pano, zotayidwa kasakaniza wa kanyumba kamangidwe ka magalimoto Launch akulamulidwa ndi m'badwo woyamba ndi aloyi m'badwo wachiwiri akuimiridwa ndi 2A12 ndi 7A09, pamene mayiko akunja alowa m'badwo wachinayi wa kanyumba kamangidwe kazitsulo zotayidwa (7055 alloy ndi 7085 alloy), amagwiritsidwa ntchito kwambiri chifukwa cha mphamvu zawo zambiri, otsika kuzimitsa tilinazo ndi notch tilinazo. 7055 ndi aloyi wa Al-Zn-Mg-Cu-Zr, ndipo 7085 ndi aloyi wa Al-Zn-Mg-Cu-Zr, koma zonyansa zake za Fe ndi Si ndizochepa kwambiri, ndipo Zn zili pamwamba pa 7.0% ~ 8.0%. Ma aloyi a m'badwo wachitatu wa Al-Li woimiridwa ndi 2A97, 1460, ndi zina zotero agwiritsidwa ntchito m'mafakitale akunja amlengalenga chifukwa cha mphamvu zawo zapamwamba, modulus yapamwamba, komanso kutalika kwake.
Ma composites a aluminiyamu opangidwa ndi particle-reinforced matrix ali ndi ubwino wa modulus wapamwamba ndi mphamvu zambiri, ndipo angagwiritsidwe ntchito m'malo mwa 7A09 alloys kuti apange zomangira za semi-monocoque cabin. The Institute of Zitsulo Research, Chinese Academy of Sciences, Harbin Institute of Technology, Shanghai Jiaotong University, etc. achita ntchito yambiri mu kafukufuku ndi kukonzekera tinthu analimbitsa zotayidwa masanjidwewo composites, ndi kupambana kochititsa chidwi.
Al-Li alloys amagwiritsidwa ntchito muzamlengalenga zakunja
Kugwiritsa ntchito bwino kwambiri pamagalimoto apamlengalenga akunja ndi aloyi ya Weldalite Al-Li yopangidwa ndi Constellium ndi Quebec RDC, kuphatikiza 2195, 2196, 2098, 2198, ndi 2050 Alloy. 2195 alloy: Al-4.0Cu-1.0Li-0.4Mg-0.4Ag-0.1Zr, yomwe ndi aloyi woyamba wa Al-Li kuti agulitsidwe bwino kuti apange matanki osungira mafuta otsika kutentha kwa rocket. 2196 alloy: Al-2.8Cu-1.6Li-0.4Mg-0.4Ag-0.1Zr, kachulukidwe kakang'ono, mphamvu yayikulu, kulimba kwapang'onopang'ono, komwe kudapangidwira mbiri ya Hubble solar frame frame, yomwe imagwiritsidwa ntchito kwambiri potulutsa mbiri yandege. 2098 alloy: Al-3.5 Cu-1.1Li-0.4Mg-0.4Ag-0.1Zr, yomwe idapangidwira kupanga HSCT fuselage, chifukwa champhamvu yake yotopa, tsopano imagwiritsidwa ntchito mu F16 fighter fuselage ndi spacecraft Falcon launch tank mafuta. . 2198 aloyi: Al-3.2Cu-0.9Li-0.4Mg-0.4Ag-0.1Zr, yogwiritsidwa ntchito pogubuduza pepala la ndege zamalonda. 2050 aloyi: Al-3.5Cu-1.0Li-0.4Mg- 0.4Ag-0.4Mn-0.1Zr, amagwiritsidwa ntchito popanga mbale zakuda kuti zilowe m'malo mwa 7050-T7451 aloyi wandiweyani mbale zopangira zida za ndege zamalonda kapena zida zoyambira rocket. Poyerekeza ndi aloyi 2195, Cu + Mn zomwe zili mu aloyi ya 2050 ndizochepa kwambiri kuti zichepetse kukhudzidwa kozimitsa ndikusunga mawonekedwe apamwamba a mbale yokhuthala, mphamvu yeniyeni ndi 4% yapamwamba, modulus yeniyeni ndi 9% yapamwamba, ndipo kulimba kwa fracture kumachulukitsidwa ndi kupsinjika kwakukulu kwa dzimbiri kusweka komanso kutopa kwakukulu kukana kukula, komanso kukhazikika kwa kutentha.
Kafukufuku waku China pakupanga mphete zomwe zimagwiritsidwa ntchito popanga roketi
Malo opangira magalimoto ku China ali ku Tianjin Economic and Technological Development Zone. Amapangidwa ndi malo opangira ma rocket ndi malo opangira, malo ogulitsa ukadaulo wamlengalenga komanso malo othandizira. Zimaphatikiza kupanga magawo a rocket, kusonkhana kwamagulu, kuyesa komaliza.
Tanki yosungiramo rocket imapangidwa polumikiza masilindala okhala ndi kutalika kwa 2m mpaka 5m. Matanki osungira amapangidwa ndi aluminiyamu alloy, choncho amafunika kugwirizanitsidwa ndi kulimbikitsidwa ndi mphete zopangira aluminiyamu. Kuphatikiza apo, zolumikizira, mphete zosinthira, mafelemu osinthira ndi magawo ena a mlengalenga monga magalimoto oyambira ndi malo opangira mlengalenga amafunikanso kugwiritsa ntchito mphete zolumikizira, kotero kuti mphete zopangira ndi mtundu wovuta kwambiri wolumikizira komanso magawo amawu. Southwest Aluminium (Group) Co., Ltd., Northeast Light Alloy Co., Ltd., ndi Northwest Aluminium Co., Ltd. achita ntchito zambiri pakufufuza ndi chitukuko, kupanga ndi kukonza mphete zopangira.
Mu 2007, Southwest Aluminiyamu inagonjetsa zovuta zaukadaulo monga kuponyera kwakukulu, kutsegulira kwa billet, kupindika kwa mphete, ndi kuzizira kozizira, ndipo adapanga mphete ya aluminiyamu yokhala ndi mainchesi a 5m. Ukadaulo wapakatikati wopangira zida zidadzaza mpata wapakhomo ndipo zidagwiritsidwa ntchito bwino ku Long March-5B. Mu 2015, Southwest Aluminium adapanga mphete ya aluminiyamu yayikulu kwambiri yokhala ndi mainchesi a 9m, ndikuyika mbiri padziko lonse lapansi. Mu 2016, Southwest Aluminiyamu bwinobwino anagonjetsa angapo makiyi umisiri pachimake monga anagudubuzika kupanga ndi kutentha mankhwala, ndipo anapanga wapamwamba-lalikulu zotayidwa aloyi kupanga mphete ndi awiri a 10m, amene anapereka mbiri dziko latsopano ndi kuthetsa vuto lalikulu laumisiri. popanga galimoto yonyamula katundu yolemetsa yaku China.
Adasinthidwa ndi May Jiang kuchokera ku MAT Aluminium
