Xa iinjineli ze-aerospace zichaza i-Inconel 718 yamagqabi einjini yomoya, imilomo yepetroli, okanye izibiyeli zesakhiwo, abakhethi nje izinto eziphathekayo-bayazibophelela kwikhonkco lokuvelisa elimele lihambise ulawulo lwe-micron-level dimensional, ukwakhiwa kweenkozo eziphindaphindiweyo, kunye ne-zero porosity kuyo yonke into yokuphosa. Yiyo loo nto kukhangelwa i Inconel 718 umzi-mveliso wotyalo-mali kunqabile ukuba iqale ngeekowuti zexabiso-kwaye phantse isoloko iphela ngenkqubo elubala, ukulandeleka kwe-metallurgical, kunye namava e-flight eqinisekisiweyo.
Kutheni i-Inconel 718 ifuna ngaphezulu kwe-Standard Casting Yazi-Njani
I-Inconel 718 ayiphoswanga njengentsimbi ye-316 engenasici. I-nickel yayo ephezulu (i-50-55%), i-niobium (4.75-5.5%), kunye ne-titanium (0.65-1.15%) idala i-sensitivity enzima kakhulu. Imingxunya ecuthekayo yenza lula. I-Microsegregation ikhokelela kwimvula yesigaba seLaves-ingakumbi kwiindawo ezishinyeneyo. Kwaye iifestile zokunyanga ukushisa zincinci: isisombululo se-anneal kwi-950-1050 ° C, emva koko siguga kwi-720 ° C kwiiyure ze-8 ezilandelwa yi-620 ° C kwiiyure ze-8. Uphose ipharamitha enye, kwaye amandla okuqina ehla nge-15%.
Siye sabona abathengi besala amaqashiso apheleleyo ngenxa yokwahluka kwezithuba zengalo zedendritic ezifihlakeleyo-ezingabonakali kwiliso lenyama kodwa ziqinisekiswe ngemephu ye-SEM-EDS. Yiyo loo nto ukugqitywa komphezulu kukodwa kungachazi umgangatho. Imalunga nendlela ijometri yepateni yewax elawula ngayo amazinga okupholisa asekuhlaleni. Indlela iqokobhe ngundo preheat ubushushu kuchaphazela ukutya interdendritic. Indlela indawo yombethe yesithando somlilo ekuchaphazela ngayo ukubalwa kweoksidi.
E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha i-Inconel 718 nganye yokuphosa njengesiganeko se-thermomechanical-hayi umsebenzi wokuphindaphinda imilo. Isiseko sethu esithobela i-ISO sisebenzisa ukugalelwa kweqokobhe levacuum, ukupholisa okulawulekayo emva kokuphoswa kwentsimbi, kunye neprofayile yexesha lokwenyani kumjikelo wonke wobushushu. Ibhetshi nganye ithwala ii-MTR ezipheleleyo: ukwakheka kweekhemikhali nge-ASTM B637 nganye, ubungakanani beenkozo nge-ASTM E112 nganye, kunye neziphumo zovavanyo lomatshini ukusuka kwisampulu zelebhu eqinisekisiweyo esikwe kugalelo olunye.
Udibaniso oluthe nkqo luSombulula iNgxaki “Yokuphosela-ku-Machining”
Uninzi lwababoneleli be-aerospace benza oomatshini bangaphandle emva kokuphosa. Oko kudala iindawo ezintathu zokungaphumeleli: ukugqwetheka kwe-thermal ngexesha lokuphumla koxinzelelo, ukungahambi kakuhle phakathi kwedatha yokuphosa kunye nokuseta ukulungiswa kwe-CNC, kunye nokungahambelani komgangatho wengqibelelo phambi kokugqithisa kokugqibela.
Singabanini bomgca wokuphosa wotyalo-mali kunye neeseli ze-CNC ezine-axis ezintlanu phantsi kophahla olunye. Oko kuthetha ukuba iqela elifanayo le-metrology liqinisekisa icandelo njenge-cast-cast kwi-Zeiss CONTURA CMM-ke inkqubo ngokuthe ngqo inkqubo elandelayo usebenzisa isakhelo sereferensi ye-GD & T efanayo. Akukho nguqulelo yenkqubo yolungelelwaniso. Akukho kuhlaziywa kwakhona. Akukho mahluko esitokhweni amangalisayo.
Umzekelo: i-fuel manifold yomthengi efunekayo ± 0.025 mm ubukhulu bodonga kwiimbambo eziyi-1.2 mm. Umnikezeli wabo wangaphambili walungisa ezo mbambo emva kokuphosa-kodwa uxinzelelo olushiyekileyo lubangele i-0.04 mm isaphetha kwi-30% yamalungu. Sayila ngokutsha isango lokungena ukuze kuncitshiswe ukuthambeka kwe-thermal, songeza ukubamba ukuphelisa uxinzelelo kwi-850 ° C ngaphambi komatshini orhabaxa, kwaye sasebenzisa iindlela zokusila ze-trochoidal ezinobunzulu be-radial eyi-0.1 mm. Isivuno sinyuke ukusuka kuma-68% ukuya kuma-99.2%.
Oku kudityaniswa kukwavumela iinkqubo ze-hybridi-ezifana nokuphosa iimilo ezikufutshane-netha kunye ne-0.3 mm yesibonelelo sesitokhwe, emva koko kugqitywe iindawo ezibalulekileyo zokutywinwa nge-electrochemical polishing ku-Ra ≤ 0.2 µm. Akukho kusila okwesibini. Akukho mngcipheko we-microcrack.
Ukuqinisekiswa kwehlabathi lokwenyani: Ukusuka kwiMizobo ukuya kwiFlight Hardware
Amaphepha athile awasileli. Amacandelo enza. Ke sivavanya i-Inconel 718 ye-aerospace casting-kungekhona nje nge-hydrostatically, kodwa ngokulinganisa okusebenzayo. Umyalelo wezindlu wempompo wamva nje uquka uvavanyo loxinzelelo lwe-cyclic kwibha ye-420 kwimijikelezo ye-10,000 ngelixa ubeka iliso ekukhutshweni kwe-acoustic. Iiyunithi ezimbini zibonise utyikityo oluvuza kancinci kumjikelo we-7,842. Unobangela weengcambu? Ukuqhekeka kobunjwa obuncinci beqokobhe ngexesha le-dewaxing, engabonakali kwi-X-reyi kodwa ibonakala ngedayi engeneyo ephuculwe kukuphazamiseka kwe-ultrasonic.
Ngoku siqhuba zonke iigobolondo ze-Inconel 718 ngokujonga i-automated optical pre-galue-ijonga iicracks ezincinci, ukufana kokuqina, kunye nentsalela ye-binder. Yongeza iiyure ze-4.2 kwiqashiso nganye kodwa isusa i-92% yokukhatywa kwasemva kwexesha.
Abathengi bethu bathumela la macandelo kwii-OEM ze-Tier 1 ze-aerospace kuwo wonke uMntla Merika naseYurophu. Baxhomekeke ekulandeleni kwethu okugcweleyo: i-casting nganye iphethe ikhowudi ye-QR edibanisa nenombolo yayo yokushisa ekrwada, i-ID ye-shell batch, i-furnace log, ingxelo ye-CMM, kunye nesiqinisekiso se-NDT. Akukho nto icingelwayo. Yonke into iyalinganiswa.
Ukukhetha i-Inconel yakho ye-718 Investment Casting Factory-Yintoni eyona nto ibalulekileyo
Sukubuza "Ngaba unokuphosa i-Inconel 718?" Buza endaweni yoko:
- Yeyiphi imveliso yakho ende eqhubekayo ye-AMS 5662 Inconel 718-ngaphandle kokuphambuka kwezinto?
- Ngaba uyalwenza uvavanyo olushushu olushushu kwiikhuphoni zamangqina ezitsalwa kulo lonke ugalelo?
- Ngaba ungabonelela ngeemephu zokuhamba okuziinkozo ezibonisa ukuqhelaniswa nedendrite ngokunxulumene neendlela zokulayisha?
- Uqinisekisa njani ukuthembeka kokungunda kweqokobhe phambi kokungena kwentsimbi?
- Uthini umyinge wakho wokuvunywa kwenqaku lokuqala lomzobo we-aerospace kunye neemfuno ze-AS9102?
Le mibuzo yahlula izixhobo ezilandela i-specs kwabo baqondayo ukuba kutheni i-spec nganye ikhona. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Sibaphendula ngedatha-hayi iincwadana. Ngenxa yokuba xa icandelo lakho lisebenza kwi-650 ° C phantsi kwe-12,000 RPM, ukunyamezela akuyiyo ithiyori. Ngumahluko phakathi kwempumelelo yobuthunywa kunye nokusilela okuyintlekele.
Ukuba ufuna i Inconel 718 umzi-mveliso wotyalo-mali eyakhelwe uxanduva lokuphendula kwi-aerospace-hayi nje amandla okuphosa-qala ngobunini benkqubo, ukuqina kwe-metallurgical, kunye ne-zero-compromise traceability. Okuseleyo kulandela.
