Xa iinjineli ze-aerospace zidinga iiblade zeinjini yomoya, imilomo yepetroli, okanye izibiyeli ezibambe i-700°C phantsi koxinzelelo lomjikelo lobushushu—utyalo-mali lokuphosa i-Inconel 718 ayisiyiyo nje inketho. Yisiseko. Kodwa ayizizo zonke iifektri ezihambisa i-microstructure efanayo, ukuphindaphindwa komgangatho, okanye ingqibelelo yomgangatho wokuphosa efunekayo kwizinto ezibalulekileyo zokubhabha. Siye sabona iindawo ezikhatywayo emva kwe-200K yeedola kwi-tooling investment-kungekhona ngenxa yeziphene zokuyila, kodwa ngenxa yokuba indlu yokuphosa yayingenalo ulawulo lwetsimbi malunga nokusabalalisa ubungakanani beenkozo kunye nemvula yesigaba se-delta kwindawo echaphazelekayo kubushushu.
Kutheni i-Inconel 718 ifuna Ngakumbi kunoTyalo-mali oluMgangatho lokuCasa
I-Inconel 718 ayiphoswanga njenge-316 engenasici. I-nickel-chromium matrix yayo ene-niobium kunye ne-titanium yokuqina kwezigaba isabela kabukhali kwiqondo lokupholisa, ubushushu bokutshisa phambi kokungunda, kunye nokufuma kwe-ambient ngexesha lokomiswa kweqokobhe. Ukupholisa ngokukhawuleza kakhulu? I-Embrittlement evela kwi-Laves isigaba sokuhlukaniswa. Ukucotha kakhulu? I-gamma-double-prime erhabaxa ithoba ubomi bokudinwa. Siqhele ukwenza umlinganiselo wesithuba sengalo yedendrite (DAS) kumacandelo anqamlezileyo-kwaye siyala iibhetshi apho i-DAS idlula i-25 µm, nokuba amandla okuqina adibana ne-spec. Ngenxa yokuba kwi-aerospace, amandla esivuno ewodwa awakuxeleli kwangaphambili ukwanda kokuqhekeka kwiindibano ezijikelezayo.
Yiyo loo nto iyinyaniso utyalo-mali lokuphosa i-Inconel 718 ifektri kufuneka idibanise izakhono ezintathu ezingenakuxoxisana: i-vacuum induction melting kunye nolawulo oluchanekileyo lwe-oxygen (<5 ppm), iinkqubo ze-ceramic shell ezilinganiswe kwi-1200 ° C + ngaphandle kokufuduka kwe-silica, kunye nesisombululo se-post-cast sonyango lobushushu kunye ne-± 3 ° C yesithando somlilo kwi-1-meter imithwalo. Ukuchithwa kwesanti akuyi kuyinqumla. I-Centrifugal casting yazisa ukuthambekela komkhombandlela. Ukuphosa utyalo-mali oluchanekileyo kuphela olunikezela amandla e-isotropic kunye nokunyamezelana okuqinileyo-± 0.05 mm kwiindawo ezibalulekileyo ze-airfoil-i-FAA AC 20-108 kunye ne-EASA CS-E zifuna iNqanaba le-21G imvume yokuvelisa.
Yintoni eyahlula i-Foundry eSebenza ngokuPhezulu (Ngaphaya kweziQinisekiso)
Iziqinisekiso ezifana ne-AS9100 Rev D okanye i-NADCAP Heat Treat zikuxelela ukuba ivenkile ithobela *amabango*. Ukusebenza kwehlabathi lokwenyani kubonakala kwiindlela ezine ezibonakalayo:
- Ukulandeleka kwezinto phantsi ukuya kwibhetshi enyibilikayo-hayi nje amanani amaninzi, kodwa iingxelo ezigcweleyo ze-spectrographic (ICP-OES + OES), iimephu zokuhamba okuziinkozo, kunye nedatha yovavanyo lokuqhekeka kwe-creep egcinwe kwi-EN 10204 3.1 nganye.
- Ukuqinisekiswa kwenkqubo phambi kokugalelwa kokuqala-imodeli ye-thermal yeendlela zokuqinisa usebenzisa i-MAGMASOFT®; uqinisekiso oluqikelele ukuba iindawo ezishushu zihambelana ne-X-reyi ye-porosity scan
- Akukho "ibhokisi emnyama" egqityiweyo-iparamitha zombane ezifakwe kwindawo nganye, hayi ngeshifti nganye; uburhabaxa bomphezulu (Ra) obulinganiswa ngeeprofilometers zoqhagamshelwano kwimigangatho esebenzayo, hayi nje amakhuphoni amangqina
- Ukwaziwa kwemowudi yokusilela kufakwe ekucaphuleni-ukuba umzobo wakho ubiza udonga lwe-0.8-mm kwi-fillet yoxinzelelo oluphezulu, baya kuyihlaba umkhosi njengomngcipheko ophezulu we-microporosity kwaye bacebise ubuncinci be-1.2-mm ubukhulu obuxhaswe lulungelelwaniso lwangaphambili lwe-FEA.
Abanye banokuphikisa ukuba iziseko zaselunxwemeni azikwazi ukuhambelana nobungqongqo benkqubo yaseNtshona. Nangona kunjalo, siye saphicotha izibonelelo eQingdao apho abaqhubi bahlengahlengisa igobolondo lokutshiswa kwegobolondo ngokusekwe kufundo lwexesha langempela le-thermocouple ukusuka kwi-sensor point point-hayi itafile yexesha elimiselweyo lobushushu. Elo nqanaba lolawulo oluguquguqukayo lahlula abatyali bempahla kumaqabane aphatha umsebenzi ngamnye we-Inconel 718 njengovavanyo lwesinyithi oluneziphumo eziqinisekisiweyo zokubhabha.
Indlela Udibaniso oluthe nkqo luSombulula ngamanqaku eentlungu zeMveliso yokwenyani
Amakhonkco okubonelela nge-aerospace ayawa xa kusakhiwa, ukwenziwa ngoomatshini, kunye nokuhlola kuhlala kwizakhiwo ezahlukeneyo-okanye okubi ngakumbi, kumazwe ahlukeneyo. Silandele iiprojekthi zilibazisekile iiveki ezili-11 ngenxa yokuba umthengisi othunyiweyo uthunyelwe kwivenkile ye-CNC engakhange ilinganise i-probe yayo ye-Inconel yokwandiswa kwe-thermal coefficient. Isiphumo? I-37% yamalungu oomatshini awaphumelelanga ukuqinisekiswa kokugqibela kweCMM kwidatum B.
Yiyo ke loo nto ibalulekileyo yokuthengisa ngaphandle komthungo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Iqela elifanayo eliseta iqokobhe le-ceramic likwacwangcisa i-5-axis ye-DMG MORI NT uthotho lwe-machining ekufutshane-usebenzisa iindlela zesixhobo ezilungiselelwe ukuthambekela kokuqina komsebenzi ka-Inconel. Akukho ukulungiswa kwakhona. Akukho zimpazamo zesixokelelwano sokuguqulela. Akukho kulinda i-callouts ye-GD&T ukuba itolikwe kuyo yonke imiqobo yolwimi. Indawo yabo ehambelana ne-ISO iqhuba ukuphosa, ukushisa ukushisa, i-CNC, kunye ne-CMM kwindawo enye elawulwa yimozulu-ukusika ixesha elihamba phambili nge-40% kwi-oda eliphakathi kunye ne-slashing scrap evela ekunxibelelaneni kakubi.
Iiprothokholi zabo zokuhlola ezibhaliweyo zibandakanya ukuqinisekiswa okunyanzelekileyo kwe-etch-and-micrograph yolwahlulo lwe-interdendritic kwiqashiso ngalinye lesithathu. Bafumana iibhilidi ze-Inconel 718 kuphela kwii-mills ezinesatifikethi se-AMS 5662-kunye nezatifikethi ze-cross-check ngokuchasene neengxelo zovavanyo lwe-mill ngaphambi kokukhulula. Olu ayiloluhlu lokuthotyelwa koluhlu. Kukuncitshiswa komngcipheko owenziwe kukuhamba komsebenzi.
Ukukhetha uTyalo-mali lwakho lokuphosa i-Inconel 718 Factory: Uluhlu lokuHlola oluSebenzayo
Phambi kokusayina i-NDA, buza le mibuzo mihlanu-kwaye ufune ubungqina, hayi izithembiso:
- Ngaba ungasibonisa ingxelo yamva nje yerediyo (ASTM E192) kwi-Inconel 718 yokuphosa ehambelana nejometri yethu kunye nodidi lobunzima?
- Sithini isithuba sakho esikhulu esiqinisekisiweyo se-dendrite ingalo kwiindonga ezingaphantsi kwe-2 mm ubukhulu-kwaye uyiqinisekisa njani?
- Ngaba uyalwenza unyango lwesisombululo sobushushu endlwini? Ukuba ewe, yintoni iqondo lobushushu lesithando sakho kwi-AMS 2750E nganye?
- Uyiphatha njani idimensional drift phakathi kwe-as-cast kunye ne-post-heat-treat-states? Nika i-algorithm yakho yembuyekezo ecuthekileyo.
- Ngaba unokwabelana ngephakheji ye-PPAP egqityiweyo-kubandakanya i-MSA, iitshathi ze-SPC zemilinganiselo ebalulekileyo, kunye nokulandelelwa kwe-cert yezinto eziphathekayo-kwicandelo elifanayo le-aerospace?
Ukuba iimpendulo ziza njengamanqaku embumbulu ngaphandle kwedatha, hamba. Ukuba bayathandabuza kumbuzo #2, hamba. Ilungelo utyalo-mali lokuphosa i-Inconel 718 ifektri uthetha ngeemicrons, izidanga ngokukaCelsius, nangemifanekiso emincinane—hayi amazwi okuthengisa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngale ndlela yonke imihla. Akunjalo nje-kodwa njengenkqubo eqhelekileyo. Ugxininiso lwabo luhlala lumxinwa: amacandelo amashishini aphezulu alloy apho ukungaphumeleli kungeyona inketho. Njengoko i-aerospace ityhalela kumlinganiselo ophezulu wokudlula kunye namathuba amade enkonzo, olo qeqesho luba ngumahluko phakathi kwesiqinisekiso kunye nokukhatywa. Ikamva alikho kwelona siseko likhulu—kodwa lelo elilinganisa imida yeenkozo njengewotshi, ligcina wonke umjikelo we-thermal, kwaye liphatha umzobo wakho njengekhontrakthi yesinyithi.
