Iyo abashinzwe icyogajuru bagaragaje Inconel 718 kuri blade ya turbine, lisansi ya lisansi, cyangwa imitwe yubatswe, ntabwo bahitamo ibikoresho-biyemeje urwego rukora rugomba gutanga urwego ruciriritse rwa micron, imiterere yisubiramo, hamwe na zeru muri buri casting. Niyo mpamvu gushakisha an Inconel 718 uruganda rushora imari gake cyane itangirana nibiciro - kandi hafi ya byose birangirana no gukorera mu mucyo, gukurikiranwa na metallurgical, hamwe nuburambe bwibikoresho byindege byagaragaye.
Kuki Inconel 718 isaba ibirenze ibyo gukina bisanzwe-Uburyo
Inconel 718 ntabwo ikozwe nka 316 ibyuma bitagira umwanda. Nikel nyinshi (50-55%), niobium (4,75-5.5%), hamwe na titanium (0,65-1.15%) itera ibyiyumvo bikabije. Kugabanya imyenge bigabanuka byoroshye. Microsegregation iganisha ku mvura igwa-cyane cyane mubice byimbitse. Kandi idirishya ryo gutunganya ubushyuhe ni rito: igisubizo anneal kuri 950-1050 ° C, hanyuma ugasaza kuri 720 ° C mumasaha 8 ugakurikirwa na 620 ° C kumasaha 8. Kubura ikintu kimwe, kandi imbaraga zingana zigabanuka 15%.
Twabonye abakiriya banga ubufindo bwose kubera gutandukanya amaboko ya dendritic yoroheje atandukanye - bitamenyekana mumaso ariko byemejwe hakoreshejwe ikarita ya SEM-EDS. Niyo mpamvu kurangiza hejuru yonyine bidasobanura ubuziranenge. Nibyerekeranye nuburyo ibishashara geometrie igenzura igipimo cyo gukonjesha cyaho. Uburyo ibishishwa byerekana ubushyuhe bugira ingaruka ku kugaburira interdendritic. Ukuntu itanura ryikime cyikime bigira ingaruka kumibare ya oxyde.
Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dufata buri mukinnyi wa Inconel 718 nkibikorwa bya termo-mashini-ntabwo ari umurimo wo kwigana imiterere. Uruganda rwa ISO rwujuje ibyangombwa rukoresha vacuum ifashwa nigikonoshwa, kugenzura-gukonjesha nyuma ya annealing, hamwe nubushyuhe bwigihe-bushyashya kuri buri cyerekezo cyubushyuhe. Buri cyiciro gitwara MTRs yuzuye: ibigize imiti kuri ASTM B637, ingano yingano kuri ASTM E112, hamwe n ibisubizo byikizamini cya mashini bivuye muri laboratoire yemewe yaciwe kumasuka amwe.
Kwishyira hamwe guhagaritse gukemura ikibazo cya "Casting-to-Machine Handoff"
Abatanga ibyogajuru benshi batanga imashini nyuma yo gukina. Ibyo bitera ingingo eshatu zananiranye: kugoreka ubushyuhe mugihe cyo kugabanya imihangayiko, kudahuza hagati yo guta datum na CNC fixture, hamwe nuburinganire bwubuso budahuye mbere yo gusya bwa nyuma.
Dufite umurongo wo gushora imari hamwe na selile eshanu za CNC munsi yinzu. Ibyo bivuze ko itsinda rimwe rya metrologiya ryemeza igice kimwe kuri Zeiss CONTURA CMM - hanyuma igahita itegura ibikorwa bizakurikiraho ukoresheje ikarita imwe ya GD&T. Nta guhuza sisitemu yo guhindura. Nta kongera kubara. Ntibitangaje gutandukana.
Kurugero: lisansi yumukiriya isabwa ± 0,025 mm yuburebure bwurukuta kurubavu rwa mm 1,2. Ababitanze mbere batunganije izo mbavu nyuma yo guterwa - ariko guhangayika gusigaye byatumye umuheto wa mm 0,04 mubice 30%. Twongeye gushushanya amarembo kugirango tugabanye imashanyarazi yumuriro, twongeramo imbaraga zo kugabanuka kuri 850 ° C mbere yo kuyikora nabi, kandi dukoresha inzira yo gusya trochoidal hamwe na 0.1 mm zubujyakuzimu. Umusaruro wavuye kuri 68% ugera kuri 99.2%.
Uku kwishyira hamwe kandi gushoboza uburyo bwo kuvanga-nko gutera inshundura hafi ya net hamwe na 0.3 mm y'amafaranga yatanzwe, hanyuma ukarangiza ibintu bifatika bifunga amashanyarazi hamwe na amashanyarazi ya Ra ≤ 0.2 µm. Nta gusya kwa kabiri. Nta ngaruka za microcrack.
Kwemeza-Kwisi-Kwisi: Kuva Gushushanya Kubikoresho Byindege
Impapuro zihariye ntizinanirwa. Ibigize. Turagerageza-kugerageza buri kirere cyo mu kirere cya Inconel 718 - ntabwo ari hydrostatike gusa, ahubwo hamwe no kwigana imikorere. Icyemezo cyamazu ya pompe giheruka harimo gupima umuvuduko wikigereranyo kuri 420 kumirongo 10,000 mugihe ukurikirana ibyuka bihumanya. Ibice bibiri byerekanaga umukono wa micro-leak kuri cycle 7.842. Impamvu? Ibishishwa bito byacitse mugihe cya dewaxing, bitagaragara kuri X-ray ariko bikamenyekana hakoreshejwe irangi ryinjira ryongerewe imbaraga na ultrasonic agitation.
Ubu dukoresha ibishishwa byose bya Inconel 718 dukoresheje igenzura ryikora rya optique mbere yo gusuka - kugenzura micro-crack, gutwikira uburinganire bwuburinganire, hamwe nibisigisigi bya binder. Yongeraho amasaha 4.2 kuri tombora ariko ikuraho 92% yo kwangwa-gutinda.
Abakiriya bacu bohereza ibyo bice muri TEM 1 yo mu kirere OEM muri Amerika y'Amajyaruguru n'Uburayi. Bishingikiriza kumurongo wuzuye: buri casting itwara QR code ihuza numero yubushyuhe bwibikoresho fatizo, igikonoshwa cyicyuma, igiti cy itanura, raporo ya CMM, nicyemezo cya NDT. Nta kintu na kimwe gifatwa. Ibintu byose birapimwe.
Guhitamo Inconel yawe 718 Uruganda rwo Gutera Ishoramari - Niki Mubyukuri
Ntubaze “Urashobora gutera Inconel 718?” Baza aho:
- Nibihe bicuruzwa byawe birebire bikomeza gukoresha AMS 5662 Inconel 718-utatandukanije ibintu?

Ibi bibazo bitandukanya ibikoresho bikurikiza ibisobanuro kubantu bumva impamvu buri spec ibaho. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Turabasubiza dukoresheje amakuru - ntabwo ari udutabo. Kuberako iyo ibice byawe bikora kuri 650 ° C munsi ya 12,000 RPM, kwihanganira ntabwo ari theoretical. Ni itandukaniro hagati yo gutsinda ubutumwa no gutsindwa gukabije.
Niba ukeneye an Inconel 718 uruganda rushora imari yubatswe kubyogajuru-byo kubazwa-ntabwo ari ubushobozi bwo guta gusa-tangirana na nyirubwite, ibyuma bya metallurgjique, hamwe na zeru-guhuzagurika. Ibisigaye birakurikira.
