Akatswiri opanga zakuthambo akatchula Inconel 718 ya ma turbine blade, ma nozzles amafuta, kapena mabulaketi omangika, samangosankha zinthu - akudzipereka ku gulu lopanga lomwe liyenera kuwongolera mawonekedwe a micron, kapangidwe ka tirigu wobwerezabwereza, ndi zero porosity pakuponya kulikonse. Ndicho chifukwa chake kufufuza kwa a Inconel 718 fakitale yopanga ndalama kawirikawiri zimayamba ndi mitengo yamtengo wapatali-ndipo nthawi zonse zimathera ndi kuwonekera kwa ndondomeko, kufufuza kwazitsulo, ndi chidziwitso cha hardware chotsimikiziridwa.
Chifukwa Chake Inconel 718 Imafuna Zambiri Kuposa Kuponyera Kwayekha Kudziwa Motani
Inconel 718 sichimaponyedwa ngati chitsulo chosapanga dzimbiri cha 316. Nickel yake yapamwamba (50-55%), niobium (4.75-5.5%), ndi titaniyamu (0.65-1.15%) imapanga chidwi cholimba kwambiri. Mabowo osweka amapangika mosavuta. Microsegregation imatsogolera ku Laves gawo mvula-makamaka m'magawo okhuthala. Ndipo mawindo opangira kutentha ndi opapatiza: yankho la anneal pa 950-1050 ° C, kenako kukalamba pa 720 ° C kwa maola 8 ndikutsatiridwa ndi 620 ° C kwa maola 8. Pophonya gawo limodzi, ndipo mphamvu zamakokedwe zimatsika 15%.
Tawona makasitomala akukana maere onse chifukwa cha kusiyana kwakutalika kwa manja kwa dendritic-osawoneka ndi maso koma kutsimikiziridwa ndi mapu a SEM-EDS. Ichi ndichifukwa chake kutsirizitsa pamwamba kokha sikumatanthawuza khalidwe. Ndizokhudza momwe geometry ya sera imawongolera kuzizira kwanuko. Momwe chipolopolo cha nkhungu chimatenthetsera kutentha kumakhudza kudya kwa interdendritic. Momwe mame a ng'anjo amakhudzira kuchuluka kwa oxide.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timagwiritsa ntchito Inconel 718 iliyonse ngati chochitika cha thermomechanical-osati ntchito yobwerezabwereza. Malo athu ogwirizana ndi ISO amagwiritsa ntchito zipolopolo zothandizidwa ndi vacuum, kuziziritsa kozizira pambuyo poponyedwa, komanso mbiri yanthawi yeniyeni pa kutentha kulikonse. Gulu lililonse limanyamula ma MTR athunthu: kapangidwe ka mankhwala pa ASTM B637, kukula kwambewu pa ASTM E112, ndi zotsatira zamakanika kuchokera ku zitsanzo za labotale zotsimikizika zodulidwa kuchokera kutsanuli komweko.
Kuphatikiza Koyima Kumathetsa Vuto la "Casting-to-Machining Handoff".
Ambiri opanga zinthu zakuthambo amapangira makina akunja pambuyo poponya. Izi zimapanga malo atatu olephera: kupotoza kwa kutentha panthawi yopuma kupsinjika, kusalumikizana bwino pakati pa datum ndi CNC fixture setup, komanso kusagwirizana kwapamtunda pamaso pa mphero yomaliza.
Tili ndi ma cell a CNC okhala ndi ma axis asanu pansi pa denga limodzi. Izi zikutanthauza kuti gulu lomwelo la metrology limatsimikizira gawo la Zeiss CONTURA CMM-kenako amakonza opareshoni yotsatira pogwiritsa ntchito mawonekedwe omwewo a GD&T. Palibe kumasulira kwadongosolo. Palibe kubwereza. Palibe zodabwitsa zamitundu yosiyanasiyana.
Mwachitsanzo: mafuta ochuluka a kasitomala amafunikira ± 0.025 mm makulidwe a khoma pa nthiti za 1.2 mm. Wowagulitsira m'mbuyomu adapanga nthitizo ataponya - koma kupsinjika kotsalira kunapangitsa uta wa 0.04 mm mu 30% ya magawo. Tinakonzanso khomo kuti tichepetse kutentha, kuwonjezera mphamvu yochepetsera nkhawa pa 850 ° C tisanapange makina ovuta, ndikugwiritsanso ntchito njira za trochoidal mphero ndi kuya kwa 0.1 mm radial. Zokolola zidalumpha kuchoka pa 68% kufika pa 99.2%.
Kuphatikiza uku kumathandizanso njira zosakanizidwa-monga kuponya mawonekedwe apafupi ndi ukonde ndi 0.3 mm stock allowance, kenako kumaliza malo ovuta osindikizira ndi electrochemical polishing ku Ra ≤ 0.2 µm. Palibe akupera yachiwiri. Palibe chiopsezo cha microcrack.
Kutsimikizika Kwapadziko Lonse: Kuchokera Kujambula kupita ku Flight Hardware
Mapepala apadera samalephera. Components kuchita. Chifukwa chake timayesa kuyesa kwa ndege iliyonse ya Inconel 718-osati hydrostatically, koma ndi kayeseleledwe kogwira ntchito. Dongosolo lanyumba laposachedwa lapampu limaphatikizapo kuyezetsa kuthamanga kwa cyclic pa bar 420 kwa mizungu 10,000 ndikuwunika kutulutsa kwamphamvu. Magawo awiri adawonetsa siginecha yaying'ono yotayikira pa 7,842. Choyambitsa? Minor chipolopolo nkhungu akulimbana pa dewaxing, wosaoneka ndi X-ray koma detectable kudzera utoto lolowera kumatheka ndi akupanga mukubwadamuka.
Tsopano timayendetsa zipolopolo zonse za Inconel 718 poyang'ana zisanadze zodziwikiratu - kuyang'ana ming'alu yaying'ono, makulidwe ofanana, ndi zotsalira za binder. Imawonjezera maola 4.2 pagawo lililonse koma imachotsa 92% yakukanidwa mochedwa.
Makasitomala athu amatumiza magawowa ku Tier 1 Aerospace OEMs kudutsa North America ndi Europe. Amadalira kutsata kwathu kwathunthu: kuponyedwa kulikonse kumakhala ndi nambala ya QR yolumikizana ndi nambala yake ya kutentha, ID ya zipolopolo, chipika cha ng'anjo, lipoti la CMM, ndi chiphaso cha NDT. Palibe chomwe chimaganiziridwa. Zonse zimayesedwa.
Kusankha Fakitale Yanu ya Inconel 718 Investment Casting-Chofunika Kwambiri
Osafunsa "Kodi mutha kuponya Inconel 718?" Funsani m'malo mwake:
- Kodi AMS 5662 Inconel 718 ndi iti yomwe mumapanga mosalekeza-popanda kusokonekera?
- Kodi mumachita kuyesa kwamphamvu pamakuponi amboni omwe amachotsedwa pakuthira kulikonse?
- Kodi mungapereke mamapu oyendera mbewu omwe akuwonetsa momwe dendrite amayendera potengera njira zonyamula?
- Kodi mumatsimikizira bwanji kukhulupirika kwa nkhungu musanalowe zitsulo?
- Kodi chivomerezo chanu cha nkhani yoyamba ndi yotani pa zojambula zakuthambo zomwe zili ndi zofunikira za AS9102?
Mafunsowa amalekanitsa malo omwe amatsatira zotsimikizika kuchokera kwa iwo omwe amamvetsetsa chifukwa chake chilichonse chilipo. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timawayankha ndi data-osati timabuku. Chifukwa pamene gawo lanu likugwira ntchito pa 650 ° C pansi pa 12,000 RPM, kulolerana sikongoyerekeza. Ndiko kusiyana pakati pa kupambana kwa utumwi ndi kulephera koopsa.
Ngati mukufuna Inconel 718 fakitale yopanga ndalama zopangira kuyankha pazamlengalenga-osati kungoponyera mphamvu-kuyamba ndi umwini wazinthu, kukhwima kwazitsulo, ndi kutsata ziro-kunyengerera. Ena onse amatsatira.
