Ukusetjenziswa okuthileko kwe-aluminium alloy castings emkhunjini

Ukusetjenziswa okuthileko I-Aluminium Alloy Castings emkhunjini wesikhala

Ngokuthuthukiswa okurhabako kwethekhnoloji ye-aerospace, ukufakwa kwe-aluminiyamu ziya ngokuya zisetjenziswa ekwenziweni kwemikhumbi yomkhathi. Iinhlanganisela ze-aluminium sele ziyinto eqakathekileko ekwenziweni kwemikhumbi yomkhathi ngebanga lezakhiwo zazo ezihlukileko zomzimba nezomtjhini. I-atikili le izakucoca ngokunabileko ngokusetjenziswa okuthileko kwe-aluminium alloy castings emkhunjini, kanye neenzuzo kanye neenqophiso zesikhathi esizako ezilethako.

1. Iinzuzo ze-aluminium alloy castings emkhunjini

(I) Ukulula nokuqina okukhulu

I-aluminium alloy yinto elula neqinileko yensimbi. I-gravity yayo ekhethekileko ingaba yingcenye eyodwa kwezintathu yensimbi, kodwana amandla wayo akhethekileko angama-35% aphezulu kunaleyo ye-carbon steel ejayelekileko. Ineempawu ezihle khulu zemitjhini ezifana namandla wokudonsa kanye namandla wokukhiqiza. Ukusetjenziswa kwe-aluminium alloys kungehlisa khulu ubudisi bomkhumbi begodu kuthuthukise umthwalo nokusebenza kwendiza. Ukwenza isibonelo, ama-44% wesisindo sendiza yabagibeli ye-Airbus A380 yakhiwe ngama-aluminium alloys.

(II) Ukujamelana nokugqwala okuhle khulu
Iinhlanganisela ze-aluminiyamu zinokujamelana nokugqwala okuhle nokubekezelela kuhle ama-esidi amanengi nama-alkali. Lokhu kuqakatheke khulu eenkhunjini ezisebenza emoyeni isikhathi eside. Iingcenye ze-aluminiyamu zingasetjenziselwa ukwenza igobolondo langaphandle leemphaphamtjhini, kanye namabhakede namagobolondo weensetjenziswa ezihlukahlukeneko zeenqhema zeenqhema zeenqhema.
(III) Ukudlulisa ukutjhisa okuphezulu
Ukudlulisa ukutjhisa kwe-aluminium alloy kuhle khulu, okwenza bona kukghoneke ukukhiqiza ezinye iingcenye ezitlhoga ukusebenza kuhle kokudlulisa ukutjhisa, njengama-heat sink, ama-cooler kanye namapayipi wokudlulisa ukutjhisa eenjinini zeenqhema zeenqhema.
(IV) Ubulula bokucubungula nokubunjwa
I-aluminium alloy ineplastiki ehle begodu isebenza kuhle, okwenza bona kube lula ukuyenza ibe ziingcenye ezihlukahlukeneko. Ukungezelela, i-aluminium alloy ingasetjenzwa ngeendlela ezihlukahlukeneko, ezifana nokukhipha, ukulula, ukudweba okubandako, ukuwelda, ukuphosa nezinye iindlela.

2. Ukusetjenziswa okuthileko kwe-aluminium alloy castings emkhunjini
(I) Iingcenye zenjini
I-Aluminiyamu Ukunemba kwe-Alloy ukuphosa kusetjenziswa khulu ekwenzeni amalunga wenjini, njengama-turbine blade, ama-intake guide vanes kanye namadiski we-turbine. Ikambiso yokuphosa ngokunembileko ingakhiqiza iingcenye zamajamo ahlangahlangeneko begodu iqinisekise ukunemba kwazo ngobukhulu kanye nekhwalithi yendawo, ngaleyindlela kuthuthukise ukusebenza nokusebenza kuhle kwenjini. Ukwenza isibonelo, idiski ye-turbine yingcenye eqakathekileko ekufuze ibe namandla amakhulu begodu ibe lula ngombana itlhoga ukujamelana namazinga womtjhiso aphezulu khulu kanye nokugandeleleka. I-aluminium alloy die casting yindlela ehle khulu yokukhiqiza amadiski we-turbine asezingeni eliphezulu, anesimo esiyinkimbinkimbi.
(II) Iingcenye zesakhiwo sendiza
Ithekhnoloji yokuphosa i-aluminiyamu ingasetjenziselwa ukukhiqiza iingcenye zesakhiwo seenqhema zeenqhema zeenqhema, ezifana neenhlanganisi ze-fuselage, izakhiwo ezisekelako kanye namathangi wephethiloli. Ukuphosa ngokunembileko kunganciphisa ubudisi beengcenye, kuthuthukise amandla nokuqina kwesakhiwo, begodu kunikele ibhanoyi ukusebenza kuhle kokuphapha nokusebenzisa kuhle amafutha. Ukwenza isibonelo, ama-44% wesisindo sendiza yabagibeli ye-Airbus's A380 yenziwe nge-aluminium alloy.
(III) Iinsetjenziswa ze-Aerospace
Ukufakwa kwe-aluminium ngokunembileko nakho kudlala indima eqakathekileko ekwenziweni kwemitjhini ye-aerospace. Ukwenza isibonelo, ukwakhiwa kweenthuthi zeenqhema, iingcenye zokukhamba kanye namadivayisi wokuhlala. Ikambiso yokuphosa ngokunembileko ingaqinisekisa ukunemba nokuthembeka kwamadivayisi la begodu ihlangabezane neemfuneko eziqinileko zokuthunywa emkhathini.
(IV) Iingcenye zesathalayithi
I-aluminium alloy die castings nayo isetjenziswe khulu ekwenzeni amasathalayithi we-aerospace kanye neengcenye zama-rocket. Ukwenza isibonelo, igobolondo langaphandle lesathalayithi livamise ukwenziwa nge-aluminium alloy die castings enamandla amakhulu. Ukungezelela, ama-thrusters kanye nemitjhini yokukhamba nayo kufuze isebenzise i-aluminium alloy die castings ukuqinisekisa ukukhanya nokuqina kwawo.

3. Amacala wokusetjenziswa kwe-aluminium alloy castings emkhunjini womkhathi
(I) Ithekhnoloji yokukhiqiza nemikhiqizo yeengcenye eziqakathekileko zochungechunge lwe-alloy elula yeenthuthi zomkhathi
Iphrojekthi le yenze irhubhululo ngethekhnoloji yokukhiqiza isembozo somsila se-aluminium esinamandla khulu nesisezingeni eliphezulu kanye negobolondo elingaphasi le-cone, ikhabini ye-aluminiyamu ye-aluminium ehlanganisiweko ede khulu eneendonga ezincani kanye nethangi lamafutha le-aluminiyamu ye-aluminium ehlanganisiweko, kanye nekhabini ye-aluminium ye-aly ye-aluminium ehlanganisiweko, kanye nendlu ye-magnesium alloy yezinto ezikulu neziyinkimbinkimbi eziqinileko i-aluminium-magnesium alloy series ye-spacecraft. Iinqhema ezitjha ze-aluminium-magnesium alloy casting zithuthukiswe, okufaka hlangana i-aluminium alloy tail cover, lower cone shell, i-ultra-side thin-walled homogeneous homogeneous cabin, integral fuel tank, variable cross-section integral fuel tank, servo cabin, II-III stage interstage, II tail section, kanye ne-magnesium alloy cabin yesibili kanye nekhabini ye-shell shell. Ithekhnoloji le yenze ngcono izinga lethekhnoloji yokukhiqiza ukuphosa okusezingeni eliphezulu enarheni yami begodu yakhuthaza ituthuko yethekhnoloji embonini.
(II) Iragelophambili elihle khulu nokusetjenziswa kwethekhnoloji ye-aluminium alloy yeenqhema zeenqhema zeenqhema
Eminyakeni esanda kwedlula, ithekhnoloji yokukhiqiza i-aluminiyamu yeenqhema zeenqhema zenze ipumelelo ekulu yethekhnoloji, enikela ngesisombululo esitjha esilula sendawo ye-aerospace. Nayiqathaniswa neenkambo zokuphosa zendabuko, ithekhnoloji yesimanjemanje yokuphosa i-aluminium alloy inezinzuzo eziqakathekileko ezilandelako: ukuphumelela kwezakhiwo zezinto, ngokuqina kokudonsa okufinyelela ku-450-550MPa, ukunwebeka kwanda ku-8-12%, ipilo yokudinwa kwanda ngezikhathi ezi-3-5, begodu i-anisotropy yehlile yaba ngaphasi kwe-10%; ukutjhugulula ikambiso, ngokusebenzisa i-vacuum high-pressure die-casting (porosity
