Iyo abashakashatsi mu kirere bakeneye ibyuma bya turbine, lisansi ya lisansi, cyangwa imitwe yubatswe ifite 700 ° C munsi yubushyuhe bwumuriro -gushora imari Inconel 718 ntabwo ari amahitamo gusa. Nibyingenzi. Ariko ntabwo uruganda rwose rutanga microstructure imwe, gusubiramo ibipimo, cyangwa nkuburinganire bwubutaka bukenewe kubintu biguruka. Twabonye ibice byanze nyuma y $ 200K mugukoresha ibikoresho-bitatewe nubusembwa bwibishushanyo mbonera, ahubwo ni ukubera ko inzu yabakinnyi yabuze igenzura rya metallurgjique yo kugabura ingano n’imyororokere ya delta muri zone yibasiwe nubushyuhe.
Kuki Inconel 718 isaba ibirenze gushora imari isanzwe
Inconel 718 ntabwo yatewe nka 316 idafite umwanda. Matelike ya nikel-chromium hamwe na niobium na titanium ikomera bigira ingaruka zikomeye ku gipimo cyo gukonja, ubushyuhe bwashushe, ndetse nubushuhe bw’ibidukikije mugihe cyumye. Byihuta cyane? Kwinjirira muri Lave icyiciro cyo gutandukanya. Biratinda cyane? Gama ya gamma-kabiri-yibanze igabanya ubuzima bwumunaniro. Dupima buri gihe intera ya dendrite (DAS) kumirongo-kandi tukanga ibyiciro aho DAS irenga 25 µm, nubwo imbaraga zingana zihura na spec. Kuberako mu kirere, gutanga umusaruro byonyine ntibiteganya gukwirakwira mu nteko zizunguruka.
Niyo mpamvu ari ukuri gushora imari Inconel 718 uruganda igomba guhuza ubushobozi butatu butavugwaho rumwe: vacuum induction gushonga hamwe no kugenzura neza ogisijeni (<5pm) Gutera umucanga ntibizagabanya. Centrifugal casting itangiza icyerekezo kibogamye. Gusa ishoramari ryuzuye ritanga imbaraga za isotropic no kwihanganira gukomeye - ± 0,05 mm hejuru yikirere gikomeye - ibyo FAA AC 20-108 na EASA CS-E bisaba igice cya 21G cyemewe.
Niki Gishyiraho Urwego Rushinzwe-Ibikorwa Bitandukanye (Kurenga Impamyabumenyi)
Impamyabumenyi nka AS9100 Rev D cyangwa NADCAP Ubushyuhe Bwakubwira iduka * isaba * kubahiriza. Imikorere-yisi igaragara mumyitwarire ine igaragara:
- Gukurikirana ibikoresho kugeza kumashanyarazi—Ntabwo ari imibare myinshi, ariko raporo yuzuye yerekana amashusho (ICP-OES + OES), amakarita yerekana ingano, hamwe namakuru yikizamini cyo guturika yabitswe kuri EN 10204 3.1
- Kwemeza inzira mbere yo gusuka-Ubushakashatsi bwerekana inzira yo gukomera ukoresheje MAGMASOFT®; kugenzura ko ibibanza bishyushye bihuye na X-ray porosity scan
- Nta "agasanduku k'umukara" karangiza- gutoranya ibipimo byinjiye kuri buri gice, ntabwo kuri buri mwanya; Ubuso bukabije (Ra) bwapimwe na profilometero yo guhuza hejuru yimikorere, ntabwo ari coupons gusa
- Kunanirwa muburyo bwo kunanirwa guteka-Niba igishushanyo cyawe guhamagarira urukuta rwa mm-0.8 muri firime yuzuye, bazabishyira ahagaragara nkibyago byinshi kuri microporosity kandi batange byibuze umubyimba wa mm 1,2 ushyigikiwe na FEA mbere
Bamwe barashobora kuvuga ko ibishingwe byo hanze bidashobora guhuza inzira yuburengerazuba. Ariko, twagenzuye ibikoresho muri Qingdao aho abashoramari bahindura ibishishwa byo gutwika bishingiye ku gihe nyacyo cyo gusoma cya thermocouple uhereye ku cyuma cyerekana ikime-ntabwo ari imbonerahamwe ihamye yubushyuhe. Urwo rwego rwo kugenzura imihindagurikire y'ikirere rutandukanya ibicuruzwa biva mu mahanga n'abafatanyabikorwa bafata buri murimo wa Inconel 718 nk'igeragezwa rya metallurgie hamwe n'ingaruka zemewe n'indege.
Uburyo Vertical Kwishyira hamwe ikemura ibibazo byububabare nyabwo
Iminyururu yo mu kirere isenyuka iyo guta, gutunganya, no kugenzura bibera mu nyubako zitandukanye - cyangwa ibibi, ibihugu bitandukanye. Twakurikiranye imishinga yatinze ibyumweru 11 kubera ko utanga casting yoherejwe mu iduka rya CNC ritigeze rihindura iperereza ryayo kuri coefficient ya Inconel yo kwagura ubushyuhe. Igisubizo? 37% byimashini zananiwe kugenzura CMM yanyuma kuri datum B.
Niyo mpamvu rero amaboko adasubirwaho afite akamaro. Kuri QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Itsinda rimwe rishyiraho igikonoshwa ceramic kandi rirategura gahunda ya 5-axis DMG MORI NT yo gutunganya hafi-net-ukoresheje inzira zikoreshwa neza kugirango Inconel ikore akazi. Nta kongera gushiraho. Nta guhuza amakosa yo guhindura sisitemu. Nta gutegereza guhamagarwa kwa GD&T gusobanurwa hakurya y'ururimi. Ikigo cyabo cyujuje ISO gikora casting, kuvura ubushyuhe, CNC, na CMM ahantu hamwe hagenzurwa n’ikirere - kugabanya igihe cyo kuyobora ku kigero cya 40% ku bicuruzwa bito bito ndetse no guca ibicuruzwa bivuye mu itumanaho nabi.
Igenzura ryanditse ryanditse ririmo etch-na-micrografi yo kugenzura gutandukanya interdendritic kuri buri gice cya gatatu. Bakomora fagitire ya Inconel 718 gusa mu ruganda rufite ibyemezo bya AMS 5662 - hamwe na cheque-cheque yerekana raporo y'ibizamini by'urusyo mbere yo gupakurura. Ibi ntabwo ari urutonde rwubahirizwa. Ni kugabanya ingaruka zakozwe mubikorwa.
Guhitamo Igishoro cyawe Gutera Inconel 718 Uruganda: Urutonde Rufatika
Mbere yo gushyira umukono kuri NDA, baza ibibazo bitanu - hanyuma usabe ibimenyetso, ntabwo ari amasezerano:
- Urashobora kutwereka raporo ya radiografiya iheruka (ASTM E192) kuri Inconel 718 casting ihuye na geometrie yacu hamwe nicyiciro cyibiro?
- Ni ubuhe butumwa bwawe bwemewe bwa dendrite butandukanya urukuta munsi ya mm 2 z'ubugari - kandi wabigenzura ute?
- Ukora igisubizo cyubushyuhe murugo? Niba ari yego, ni ubuhe bushyuhe bw'itanura ryawe kuri AMS 2750E?
- Nigute ushobora gukemura ibipimo bigenda hagati ya as-cast na post-ubushyuhe-buvura? Tanga kugabanuka kwa algorithm.
- Urashobora gusangira paki yuzuye ya PPAP-harimo MSA, imbonerahamwe ya SPC kubipimo bikomeye, hamwe nibikoresho byerekana ibimenyetso-kubintu bisa nikirere?
Niba ibisubizo biza nkamasasu adafite amakuru, genda. Niba batindiganya kubibazo # 2, genda. Uburenganzira gushora imari Inconel 718 uruganda ivuga muri microne, dogere selisiyusi, na microstructure amashusho - ntabwo ari amagambo yo kwamamaza.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ikora ubu buryo buri munsi. Ntabwo ari ibintu bidasanzwe - ahubwo ni inzira isanzwe. Intego zabo ziguma zifunganye: ibice byinshi byinganda zinganda aho gutsindwa atari amahitamo. Mugihe icyogajuru gisunika hejuru yikigereranyo cyo hejuru kandi intera ndende ya serivisi, iyo disipuline iba itandukaniro hagati yubushobozi no kwangwa. Igihe kizaza ntabwo ari icy'uruganda runini - ahubwo ni urupima imbibi z'ingano nk'amasaha, yandika buri cyiciro cy’ubushyuhe, kandi ifata igishushanyo cyawe nk'amasezerano ya metallurgji.
