Ukumelana nokugqwala kwezinga lokushisa eliphezulu akuyona into yokuzikhethela—kuyisisekelo. Uma ama-nifold exhasi ecwebezela okubomvu oku-cherry, lapho izindlu eziphehla umoya zizungeza phakathi kuka-700°C kanye nokuphola ngokushesha, noma lapho ukusakazwa kwenqubo ene-asidi kudla nge-stainless standard engu-0.1 mm/ngonyaka, isigaba esisodwa kuphela sezinto ezibamba umugqa: ama-superalloy e-nickel-chromium afana ne-Inconel. Kodwa izinga lempahla eluhlaza lilodwa aliqinisekisi ukusebenza. Ukuthembeka komhlaba wangempela kuncike ekutheni Ingxenye ye-inconel yenziwe-hhayi nje ukuthi yenziwe ngani.
Kungani i-“Inconel” Inganele—Imayelana Nesakhiwo Esincane Esilawulwayo
Sibone amaphrojekthi amaningi kakhulu ehluleka hhayi ngenxa yokukhethwa kwe-alloy, kodwa ngenxa yokucubungula okungalawulwa. Iklayenti ku-North Sea oil & gas licacise i-Inconel 625 yezindlu zamavalvu okulawula umfutho ophezulu—labe selithola izingxenye ezinokugeleza okusanhlamvu okungahambisani, i-micro-porosity eduze nezindawo ezithinteke ukushisa, nokuqhekeka ngaphambi kwesikhathi ngemva kwemijikelezo yokushisa engu-4,200. Imbangela? Umphakeli usebenzise imishini ye-CNC ejwayelekile ezindaweni ezingenalutho ngaphandle kokuncishiswa kokunciphisa ingcindezi noma ukulawula ukuqinisa okuqondisayo. I-Inconel imelana ne-oxidation-kodwa kuphela uma isakhiwo sayo se-dendritic sihlala sifana, ukusabalalisa kwayo kwe-carbide kuhle futhi kuhlakazekile, kanye nezingcindezi zayo ezisele ngaphansi kwe-120 MPa.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Njalo Ingxenye ye-inconel iqala nge-billet eqinisekisiwe ye-AMS noma i-investimenti-cast preform—ungalinge ulahle isitoko esincibilike kabusha. Siqinisekisa ikhemistri nge-OES ngaphambi kokwenza imishini, silandelela indawo ngayinye ukusuka kulogi yesithando ukuya embikweni wokugcina we-CMM, futhi sifaka isixazululo se-annealing ku-1,095°C ±5°C ngokucishwa kwe-argon okulawulwayo. Yileyo ndlela esibamba ngayo usayizi wokusanhlamvu ku-ASTM E112 Level 5–6 kuwo wonke amajiyometri ayinkimbinkimbi njengezindlu zamasilinda wepompo ye-piston—izingxenye ebona ukushaya kwebha okungu-350 kanye nokugeleza kwe-back exhaust okungu-650°C.
Lapho Umshini Ojwayelekile Wehluleka-futhi Yini Esebenzayo Esikhundleni
I-Inconel 718 isika ku-1/3 izinga lokuphakelayo lika-316 okungenasici. Impilo yamathuluzi yehla ngo-70% njalo ngo-50°C iphakama ngaphezu kwezinga lokushisa elingu-600°C. Ezinye izitolo ziphendula ngokwehlisa yonke into—bese uyazibuza ukuthi kungani izikhathi zokuhola zifinyelela emavikini angu-14 futhi ubulukhuni bendawo bufinyelela u-Ra 3.2 µm esikhundleni sika-Ra 0.8 odingekayo.
Senza izinto ezintathu ngokuhlukile:
- I-Hybrid casting-machining workflows: Ngezisekelo zephampu nemizimba yama-valve, senza umumo oseduze nenethi sisebenzisa amagobolondo e-ceramic—sehlisa isikhathi somshini ngo-65% kuyilapho silondoloza ukuqondanisa okuqondile okusanhlamvu emigwaqweni yokulayisha.
- Multi-axis adaptive milling: I-Mazak INTEGREX i-200S yethu isebenzisa isinxephezelo sokuchezuka sethuluzi lesikhathi sangempela ngesikhathi sokugaya i-deep-pocket nozzles ye-Inconel 601 nozzles—igcina ukuhluka kokuqina kodonga ngaphansi kuka-±0.05 mm ngisho naku-12:1 ukujula ukuya kobubanzi izilinganiso.
- Ukuzinzisa kwangemva kwenqubo: Yonke imishini Ingxenye ye-inconel ithola impumuzo ye-vibratory stress (VSR) ku-28 Hz imizuzu engu-45 ngaphambi kokuhlolwa kokugcina—isika ukuhlanekezela ezindlini ezinezindonga ezincane ngo-80% uma kuqhathaniswa nokuguga okushisayo kuphela.
Lokhu akuwona umbono. Kuyindlela esilethe ngayo izingxenye zepompo ye-cobalt-alloy 6 engu-217 AMS 5387 ku-OEM ye-hydraulic yaseJalimane—enokuthobelana kwe-GD&T Zone okugcinwe ku-±0.015 mm kuma-datum angu-12 abalulekile, ukusebenza kabusha okuyiziro, kanye nokulandeleka okugcwele kokuncibilika kwenombolo kanye nezingodo zomjikelezo wokwelapha ukushisa.
Izindleko Ezifihliwe Zokukhetha Okubalulekile "Kwanele".
Abanye onjiniyela bazenzakalela ku-Inconel 600 ezindaweni ezicebile ngesulfure. Isebenza—izinyanga eziyisithupha. Bese ukuhlasela kwe-intergranular kuqala kuma-HAZ weld. Abanye bacacisa i-Inconel 625 yesevisi ye-chloride—ingaziba ukuthi isengozini yokubola ngaphansi kwe-pH 4.5 kanye no-80°C.
Asimane nje siqhathanise ama-alloys namashadi okushisa. Senza imephu yemvilophu egcwele yokusebenza: izinga lokushisa eliphakeme, izinga lerempu eshisayo, isivinini soketshezi, i-pH, i-chloride ppm, nephrofayela yokulayisha ngomshini. Kumaphampu omjovo wamakhemikhali aphesheya kolwandle, sishintshe iklayenti lisuka ku-Inconel 625 laya ku-Inconel 686—sengeza u-3% we-tungsten no-1.6% niobium—ukuze sinwebe impilo yesevisi kusukela ezinyangeni ezingu-9 kuya kwezingu-34 ngo-120°C, 15,000 ppm Cl⁻ brine. Kumarola agqokwa kakhulu e-winch center shaft ezimotweni zobunjiniyela, sisebenzisa izimbondela ze-cobalt-nickel ezisekelwe ku-T800 ezisetshenziswa nge-plasma transfer arc—sizuze ubulukhuni bobuso obungu-62 HRC nge-zero delamination ngemva kwemijikelezo yetorque eyizigidi ezingu-2.1.
Ukukhethwa kwezinto akukona ukuhlola kwedatha. Izingxoxo ze-metallurgical-nendawo yakho, i-geometry yakho, nezindlela zakho zokwehluleka.
Ukusuka Ekudwebeni Kuya Ekulethweni: Iyiphi Ingxenye Ethembekile Ye-Inconel Manufacturing Eyidingayo Empeleni
Ukuthembeka kuqala ngaphambi kokuthi kundiza i-chip yokuqala. Sibuyekeza zonke izimemezelo ze-GD&T—hhayi ukuthobelana, kodwa ukuze kwenziwe. Ukubekezelela isikhundla kwe-Ø0.02 mm ku-flange engu-300 mm? Kungenzeka—kodwa kuphela ngezindawo ezingaphansi komhlaba kanye nokuqinisekiswa kwe-CMM enomoya. Sihlaba umkhosi labo kusenesikhathi. Siphinde sihlole ukudonseka kuma-diaphragm e-Inconel 718 adonswe ngokujulile sisebenzisa i-digital image correlation (DIC), sibikezela ukwenziwa kwasendaweni kohlobo ngaphambi kokusikwa kwamathuluzi.
Isikhungo sethu esithobelana ne-ISO siphatha uchungechunge olugcwele: ukutholakala kwempahla eluhlaza okuqinisekisiwe, ukutshala izimali eziphasejini zangaphakathi eziyinkimbinkimbi, i-5-axis CNC yezici zangaphandle ezikwazi ukubekezelela, ukwelashwa kokushisa kwe-vacuum, nokuqedwa kwendawo—okuhlanganisa ukupholishwa ngogesi kokuhlanganiswa kwephampu yemithi kanye nezingubo ezine-anodized eziqinile zamagiya okuwina olwandle. Ukuhlolwa kokugcina kufaka phakathi ukuhlolwa kokungena kodayi nge-ASTM E1417 ngayinye, ukuskena kwe-ultrasonic nge-ASTM E1961 ngayinye, nokuhlolwa kwengcindezi yokusebenza ku-1.5× ingcindezi yokusebenza.
Uma udinga i Ingxenye ye-inconel esindayo—hhayi nje ukulingana—thintana ne-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ngqo. Siphendula imibuzo yobunjiniyela phakathi kwamahora angu-4 ebhizinisi. Sabelana ngezitifiketi zezinto ezingavuthiwe ngaphambi kokuqinisekiswa kwe-oda. Futhi sithumela imibiko enobukhulu ngayo yonke impahla ethunyelwayo.
