Akatswiri opanga zakuthambo akafuna masamba a turbine, ma nozzles amafuta, kapena mabulaketi okhazikika omwe amakhazikika pa 700 ° C pansi pa kupsinjika kwa cyclic matenthedwe—kuponya ndalama Inconel 718 si njira yokhayo. Ndilo maziko. Koma si fakitale iliyonse yomwe imapereka mawonekedwe ang'onoang'ono, kubwerezabwereza, kapena kukhulupirika kwapamtunda komwe kumafunikira pazinthu zofunika kwambiri pakuwuluka. Tawonapo magawo akanidwa pambuyo pa $ 200K pakugulitsa zida - osati chifukwa cha zolakwika zamapangidwe, koma chifukwa nyumba yoponyeramo inalibe mphamvu zowongolera zachitsulo pakugawa kukula kwa tirigu ndi mvula yagawo la delta m'dera lomwe lakhudzidwa ndi kutentha.
Chifukwa chiyani Inconel 718 Imafunikira Zambiri Kuposa Kuyika Kwazachuma Kwanthawi Zonse
Inconel 718 sichimaponyedwa ngati 316 zosapanga dzimbiri. Matrix ake a nickel-chromium okhala ndi niobium ndi titaniyamu owumitsa magawo amakhudzidwa kwambiri ndi kuzizira, kutentha kwa nkhungu kusanayambe kutentha, komanso chinyezi chozungulira poyanika zipolopolo. Kutsitsa kofulumira kwambiri? Embrittlement kuchokera ku Laves phase segregation. Mochedwa kwambiri? Coarse gamma-double-prime imachepetsa moyo wotopa. Nthawi zambiri timayesa dendrite arm spacing (DAS) m'magawo opingasa-ndi kukana magulu omwe DAS imadutsa 25 µm, ngakhale mphamvu zamakokedwe zikugwirizana ndi zina. Chifukwa mumlengalenga, mphamvu zokolola zokha sizimalosera kufalikira kwa ming'alu pamisonkhano yozungulira.
Chifukwa chake chowonadi ndalama kuponya Inconel 718 fakitale Ayenera kuphatikiza mphamvu zitatu zomwe sizingagwirizane: kusungunula kwa vacuum ndi kuwongolera bwino kwa okosijeni (<5 ppm), makina a zipolopolo za ceramic adavotera 1200 ° C+ popanda kusuntha kwa silika, ndi chithandizo cha kutentha kwa post-cast ndi ± 3 ° C ng'anjo yofanana pa katundu wa mita imodzi. Kuponya mchenga sikudula. Kuponyedwa kwa Centrifugal kumayambitsa kukondera. Kuyika ndalama molongosoka kokha kumapereka mphamvu ya isotropic ndi kulolerana kolimba—± 0.05 mm pamalo ovuta kwambiri a airfoil—omwe FAA AC 20-108 ndi EASA CS-E amafunikira kuti avomereze Gawo la 21G.
Zomwe Zimasiyanitsa Foundry Yogwira Ntchito Kwambiri (Kupitirira Zitsimikizo)
Zitsimikizo ngati AS9100 Rev D kapena NADCAP Heat Treat zimakuwuzani kuti shopu ikutsatiridwa. Zochitika zenizeni padziko lapansi zimawonekera muzinthu zinayi zowoneka:
- Kufufuza kwazinthu mpaka pagulu losungunuka-osati manambala ambiri okha, koma malipoti owoneka bwino (ICP-OES + OES), mamapu oyenda tirigu, ndi data yoyeserera yophulika yosungidwa pa EN 10204 3.1
- Kutsimikizira ndondomeko musanathire koyamba-Kutentha kwachitsanzo kwa njira zolimba pogwiritsa ntchito MAGMASOFT®; kutsimikizira kuti malo otentha amagwirizana ndi ma X-ray porosity scans
- Palibe "bokosi lakuda" kumaliza-zigawo za electropolishing zomwe zayikidwa pagawo lililonse, osati kusintha kulikonse; pamwamba roughness (Ra) kuyeza ndi profilometers kukhudzana pamalo ogwirira ntchito, osati makuponi umboni
- Kulephera mumalowedwe chidziwitso chophimbidwa mu mawu-ngati kujambula kwanu kumafuna khoma la 0.8-mm mufillet yopanikizika kwambiri, amawonetsa kuti ili pachiwopsezo chachikulu cha microporosity ndikuwonetsetsa kuti makulidwe ochepera a 1.2-mm mothandizidwa ndi kulumikizana kwa FEA kusanachitike.
Ena anganene kuti zoyambira zam'mphepete mwa nyanja sizingafanane ndi zovuta zaku Western. Komabe, tafufuza malo ku Qingdao komwe ogwira ntchito amasintha ma curve akuwotcha zipolopolo potengera kuwerengera kwanthawi yeniyeni ya thermocouple kuchokera pa sensa ya mame-osati tebulo lokhazikika la nthawi yotentha. Kuwongolera kosinthika kumeneku kumalekanitsa oponya katundu kuchokera kwa anzawo omwe amagwira ntchito iliyonse ya Inconel 718 ngati kuyesa kwazitsulo komwe kumakhala ndi zotsatira zotsimikiziridwa ndi ndege.
Momwe Kuphatikizika Kwamawonekedwe Kumathetsera Zowawa Zenizeni Zopanga
Unyolo wazamlengalenga umagwa pamene kuponyera, kukonza makina, ndi kuyendera kumakhala m'nyumba zosiyana - kapena kuipitsitsa, mayiko osiyana. Tatsata mapulojekiti omwe adachedwa kwa milungu 11 chifukwa wogulitsa adatumizidwa ku shopu ya CNC yomwe inali isanawerengere kafukufuku wake pa kuchuluka kwa matenthedwe a Inconel. Chotsatira? 37% ya magawo opangidwa ndi makina adalephera kutsimikizira komaliza kwa CMM padatum B.
Ichi ndichifukwa chake kuchita masewera olimbitsa thupi ndikofunikira. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., gulu lomwelo lomwe limayika chipolopolo cha ceramic limapanganso mndandanda wa ma 5-axis DMG MORI NT opangira makina oyandikira-kugwiritsa ntchito zida zokongoletsedwa ndi chizolowezi choumitsa ntchito cha Inconel. Palibe kukonzanso. Palibe zolakwika zomasulira zamakina. Palibe kudikirira kuti ma callout a GD&T amasuliridwe pazolepheretsa zilankhulo. Malo awo ogwirizana ndi ISO amayendetsa kuponyera, kutentha, CNC, ndi CMM mu malo amodzi olamulidwa ndi nyengo-kudula nthawi yotsogolera ndi 40% pa malamulo apakati ndi kuphwanya zinyalala za kusamvana.
Zolemba zawo zowunikira zimaphatikizanso kutsimikizika kwa etch-and-micrograph kwa tsankho la interdendritic pagawo lililonse lachitatu. Amatulutsa mabilu a Inconel 718 kuchokera ku mphero zomwe zili ndi certification ya AMS 5662-ndi ziphaso zoyang'ana motsutsana ndi malipoti oyesa mphero musanatsitse. Uku sikutsata mndandanda. Kuchepetsa chiopsezo kumapangidwira mumayendedwe a ntchito.
Kusankha Investment Casting Inconel 718 Factory: Mndandanda Wothandiza
Musanasaine NDA, funsani mafunso asanu awa, ndipo funsani umboni, osati malonjezo:
- Kodi mungatiwonetse lipoti laposachedwa la radiographic (ASTM E192) pa Inconel 718 yomwe ikufanana ndi geometry yathu ndi kalasi yathu yolemetsa?
- Kodi mutalikirana bwanji m'manja mwanu wotsimikizika wa dendrite pamakoma osakwana 2 mm ndipo mumawatsimikizira bwanji?
- Kodi mumagwira ntchito yochizira kutentha m'nyumba? Ngati inde, kutentha kwa ng'anjo yanu ndi kotani pa AMS 2750E?
- Kodi mumatani kuti muzitha kusuntha pakati pa ma as-cast ndi post-heat-treat states? Perekani ma aligorivimu anu ocheperako.
- Kodi mutha kugawana nawo phukusi la PPAP lomalizidwa - kuphatikiza ma MSA, ma chart a SPC amiyeso yovuta kwambiri, komanso kutsatiridwa kwa cert cert - pagawo lofananira lazamlengalenga?
Ngati mayankho abwera ngati zipolopolo zopanda data, chokanipo. Ngati akukayikira pafunso #2, chokanipo. Ufulu ndalama kuponya Inconel 718 fakitale amalankhula m’ma microns, madigiri seshasi, ndi zithunzi za microstructure —osati mawu oti atsatse malonda.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito mwanjira imeneyi tsiku lililonse. Osati monga kuchotsera-koma monga ndondomeko yokhazikika. Cholinga chawo chimakhalabe chochepa: zigawo za mafakitale apamwamba kwambiri pomwe kulephera sikungatheke. Pamene mlengalenga ukukankhira ku ziwerengero zapamwamba zodutsa ndi nthawi yayitali ya mautumiki, chilango chimenecho chimakhala kusiyana pakati pa kuyenerera ndi kukana. Tsogolo siliri la maziko aakulu kwambiri - koma la amene amayesa malire a tirigu ngati mawotchi, amalemba mawotchi onse, ndikuwona zojambula zanu ngati mgwirizano wazitsulo.
