Pamene mainjiniya afotokoza Mtengo wa 718, sikuti amangosankha zinthu-akudzipereka kuti azitha kukhazikika pa 650 ° C, kukana kupsinjika-kusweka kwa corrosion m'madera a mpweya wowawasa, ndi moyo wotopa pansi pa kutenthedwa kwa kutentha kwa cyclic. Koma zopangira zopangira sizitanthauza pang'ono popanda mnzake yemwe amadziwa bwino zomwe amachita m'sitolo. Ndiko kumene Inconel 718 fakitale imapeza kulemera kwake, osati m'mabuku, koma kubwerezabwereza magawo a magawo 200, potsatira GD&T pazololera za 0.005-mm, komanso modabwitsa ziro pakuwunika kwa nkhani yoyamba.
Chifukwa chiyani "Factory" ili yofunika kwambiri kuposa "Supplier" ya Inconel 718
Tawonapo ma projekiti ambiri akuyimitsidwa chifukwa kampani yogulitsa malonda idatulutsa Inconel 718 bar stock kuchokera ku mphero imodzi, kutenthetsa pa ng'anjo ya chipani chachitatu, kenako ndikuitumiza ku sitolo ya CNC popanda kuyang'anira zitsulo. Chotsatira? Kusiyanasiyana kwa microstructure pakati pa kutentha. Decarburization pamwamba pa ma flanges otembenuzidwa. Warpage yotsalira-yomwe imayambitsa kupsinjika pambuyo pakukonza komaliza-imapezeka pokhapokha pakuyezetsa ma hydraulic. A zoona Inconel 718 fakitale eni ake ndi unyolo: certified raw material traceability, in-house solution annealing and ukalamba cycles, ndi machining parameters ovomerezeka pa Inconel 718 yeniyeni—osati generic nickel-alloy presets.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Chigawo chilichonse cha Inconel 718 chimayamba ndi AMS 5662-certified billet, yotsimikiziridwa kudzera pa PMI ndi OES isanalowe mumayendedwe opangira. Sitimapereka chithandizo cha kutentha kunja. Zotenthetsera zathu zimatsata zolemba zenizeni za AMS 2750E pyrometer - ndipo timasunga mbiri yonse yotentha pagawo lililonse. Izi si zachilendo. Ndimomwe timagwirira ± 0.01 mm pa 320-mm-diameter piston pampu nyumba ya silinda pamene tikusunga Ra 0.4 µm pamwamba pa malo osindikizira mkati.
Kumene Makina Okhazikika Akulephera-ndi Zomwe Zimagwira Ntchito
Masitolo ena amatenga Inconel 718 ngati chitsulo chosapanga dzimbiri cholimba. Iwo samatero. Mlingo wake wowumitsa ntchito ndi 3 × wapamwamba kuposa 316SS. Mitengo ya chakudya imatsika 40% pambuyo pa chiphaso choyamba. Moyo wa chida umatsika ngati mphamvu yozizirira itsika pansi pa mipiringidzo 70. Tidaphunzira izi movutikira kupanga ma nozzles a AMS 5387 cobalt-nickel a manifolds othamanga kwambiri a hydraulic-mpaka tidasinthira ku zoziziritsa kukhosi zoziziritsa kukhosi, zokutira za ceramic zokhala ndi geometry yabwino, komanso njira zokhotakhota zomwe zimachepetsa nthawi.
Malo athu ogwirizana ndi ISO ali ndi malo opangira makina a 5-axis omwe ali ndi mphero zakuya zamagulu ovuta - monga njira zodutsa mkati mwa ma valve opanikizika okwana 420 bar. Timaphatikiza chithandizo cha kutentha * pakati pa * ntchito zikafunika: makina ovuta → njira yothetsera → kupsinjika maganizo → makina omaliza → zaka zouma. Kudumpha motsatizanazi kungayambitse kusokonekera kapena mphamvu zokolola zosagwirizana. Makasitomala omwe amadumpha kuwunika kwa uinjiniya nthawi zambiri amafunsa kuti, "N'chifukwa chiyani gulu lathu loyamba lidapambana CMM koma kulephera kuyesa kophulika?" Yankho silikhala chojambula - ndi njira yotenthetsera.
Cast + Machine = Ntchito Yeniyeni Yapadziko Lonse Mungathe Kuyeza
Inconel 718 singopangidwa kapena kupangidwa. Pazigawo zazikulu, zofunika kwambiri - maziko a pampu, zodzigudubuza za winch center, ma valve a m'mphepete mwa nyanja - kuyika ndalama kumapereka mawonekedwe apafupi ndi ukonde ndikuyenda bwino kwa mbewu. Koma kuponya kokha sikokwanira. Zowoneka ngati zoponyedwa zilibe kukana kutopa kofunikira pazigawo zozungulira. Chifukwa chake Inconel 718 fakitale amaphatikiza kuyika kwa ndalama ndi kumalizidwa kolondola kwa CNC: kuponyedwa ku ± 0.3 mm, kenako nkhope zosindikizira pamakina, zokhala ndi magazini, ndi mafomu a ulusi mpaka ± 0.008 mm ndi kutsimikizika kwathunthu kwa GD&T.
Timasunga kulumikizana kwaukadaulo ndi ogulitsa zinthu pakuwongolera kukula kwambewu (ASTM E112), kuphatikizika (ASTM E45), ndi zomwe zili mu delta-ferrite. Kuponyedwa kulikonse kumalandira kuwunika kwa radiographic (ASTM E94) ndi kuyezetsa kwamadzimadzi (ASTM E165). Palibe kupatula - ngakhale ma prototypes. Chifukwa mumafuta & gasi kapena kugwiritsa ntchito nyanja zam'madzi, gulu limodzi la porosity pakukweza nkhawa si "kupatuka kwakung'ono." Ndi kulephera kwamunda kuyembekezera kuchitika.
Kusankha Mnzanu wa Inconel 718: Zosakambirana Zitatu
Musanasaine PO, funsani mafunso awa-ndipo funsani umboni:
- Kodi mungandiwonetse zipika zanu zitatu zomaliza za Inconel 718? Osati kokha kutentha kokhotakhota—komanso kapangidwe ka ng’anjo ya ng’anjo, machulukidwe, nthaŵi zonyowa, ndi kuziziritsa pa AMS 2750E iliyonse.
- Kodi mumatsimikizira pambuyo pa kutentha kwa microstructure? Timapanga SEM/EDS pazigawo zodutsana kuti titsimikizire γ′ kugawa kwachangu komanso kusapezeka kwa δ-gawo pamalire a tirigu.
- Ndi nthawi iti yomwe mungakhale nayo yoyipa kwambiri pa dongosolo la magawo 15 a nyumba ya silinda ya 220-mm-yokhala ndi ma cert athunthu, malipoti a CMM, ndi zolemba za NDT? Yankho lathu ndi masiku 28 a kalendala. Osati "masabata 4-6." Osati "zimadalira." Timazitsata mu nthawi yeniyeni.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. sichidziyika ngati "fakitale ya Inconel 718" yotsatsa. Ndife amodzi - chifukwa tsiku lililonse, akatswiri athu amakasitomala amasintha ma feed potengera zomwe zidavala nthawi yeniyeni, akatswiri athu azitsulo amawunika kuuma koyerekeza ndi zotsatira zoyeserera, ndipo gulu lathu la QA limayimitsa pokhapokha poyesa magwiridwe antchito afanana ndi ntchito zomwe kasitomala amakumana nazo. Ndiko kusiyana pakati pa kufufuza ndi kuthetsa.
Ngati polojekiti yanu yotsatira ikufuna magawo a Inconel 718 omwe apulumuka maola 10,000 pa 600 ° C, asindikize modalirika pa bar 400, kapena tembenuzani popanda kudandaula pa 1,800 rpm-yambani ndi mnzanu yemwe kukhulupirika kwake kumakhala muzitsulo zawo za ng'anjo, osati tsamba lawo la webusaiti. Ufulu Inconel 718 fakitale sichimalonjeza ungwiro. Imapereka zodziwikiratu - gawo limodzi lotenthedwa, lopangidwa mwatsatanetsatane, lodziwika bwino panthawi imodzi.
