Wina akati 'nickel base', theka la chipindacho limaganizira za injini za jeti, theka lina limaganiza zamtengo wapatali, zovuta zomwe zimakhala zovuta kwambiri kuposa momwe ziyenera kukhalira. Chowonadi, monga mwachizolowezi, chimakhazikika penapake pakati pa zosokoneza. Sichipolopolo chamatsenga, koma kuzikana ngati 'zotsika mtengo zosapanga dzimbiri' ndi njira yachangu yothera ndi gawo lolephera. Vuto lenileni silimangotchula chithunzicho; zili mu zisankho zazing'ono zikwizikwi kuchokera ku sitolo yosungunula kupita kumalo omaliza opangira makina.
Lingaliro Lolakwika Lachikulu: Zonse Zikukhudza Kutentha
Ma sheet ambiri amatsogolera ndi kutentha kwambiri, ndipo sizolakwika. Koma kuyang'ana kwambiri pa mphamvu ya 1200 ° F ndipamene mapulojekiti amayamba kuyenda. Ndawonapo zojambula zomwe zimawombera pa a maziko a nickel aloyi ngati Inconel 718 chifukwa kutentha kwa ntchito kunali kokwera, kulephera kokha chifukwa cha kuwonongeka kwa chloride-induced stress corrosion pa kutentha kochepa, kosayembekezereka. Aloyiyo inali 'yokwanira' kutentha koma yosayenerera malo enieni a mankhwala. Kodi tikuphunzirapo chiyani? Mbiri yotentha ndi mutu woyamba. Muyenera dzimbiri lonse ndi makina nkhani.
Ndiye pali nthano ya weldability. Funsani wopanga zinthu ngati angathe kuwotcherera, ayankha kuti inde. Koma kodi angayiwotcherera ndikupangitsa kuti malo omwe akhudzidwa ndi kutentha asunge zomwe mudapangira? Ndiko kukambirana kosiyana. Pambuyo pa kuwotcherera kutentha mankhwala aloyi izi si maganizo; nthawi zambiri kusiyana pakati pa kusonkhana kwa phokoso ndi kung'ung'udza kwamunda kudikirira kuchitika. Tidaphunzira izi movutikira pantchito yochulukirapo zaka zapitazo, poganiza kuti PWHT wambayo ingakhale yokwanira. Sizinatero. Kutentha kwanyengo kudazimiririka, ndipo tidakhala ndi ma oxidation amalire ambewu msanga.
Apa ndipamene kuyambika kwa mnzako ndi kukonza makina kumakhala kosakambilana. Sizokhudza kugula kuponya; ndi za kugula ndondomeko yoyendetsedwa. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka makumi atatu mu zipolopolo ndi kuika ndalama, amapeza izi. Pamene mwakhala mukuthira maziko a nickel ma aloyi kwa nthawi yayitali, mwamanga laibulale ya mbiri yamatenthedwe, mapangidwe a gating, ndi njira zodyetsera za zida izi finicky. Mutha kuwapeza pa https://www.tsingtaocnc.com. Mbiri yawo si mndandanda wazinthu; ndi mbiri yamavuto omwe adathetsedwa mu cobalt ndi nickel alloys.
Kuchokera ku Melt mpaka Machining: The Real Cost Drivers
Tiyeni tikambirane za Machining, chifukwa ndi kumene bajeti mwakachetechete magazi. Anthu amayang'ana mtengo wazinthu zopangira pa kilogalamu ndikupuma. Kenako amapeza mawu oyamba akumakina ndikupuma kwenikweni. Nickel maziko ma aloyi ngati Hastelloy X kapena Waspaloy amagwira ntchito molimba ngati china chilichonse. Chida chosawoneka bwino kapena kudya kwamanyazi sikumangochepetsa; zimapanga khungu lolimba lomwe limapangitsa kuti lotsatira likhale lolimba, lomwe lingathe kuwononga gawolo.
Chinyengo ndi nkhanza, zomwe zimamveka ngati zotsutsana. Mufunika carbide yakuthwa, yapamwamba kwambiri, yolimba kwambiri pakukhazikitsa kwanu, ndipo muyenera kulowa pansi pagawo lolimba la ntchito kamodzi. Kuwala, kudula mabala ndi mdani. Nthawi ina tidayesetsa kusungira zida zamagulu a Alloy 625, pogwiritsa ntchito kuyika kwapansi pang'ono. Nthawi yozungulira idachulukanso, tidawotcha zoyikapo katatu, ndipo kumaliza kwake sikunali kovomerezeka. 'Kusunga' kumawononga kwambiri nthawi yamakina ndikukonzanso.
Ichi ndichifukwa chake masitolo ophatikizidwa ali ndi malire. Ngati bungwe lomwelo lomwe limapanga gawolo lizipanganso pa CNCs zawo, akonza kale ndalama zoyambira. Amadziwa momwe zinthu zilili pamtunda wa magawo awo ngati akuponyedwa. Palibe kuloza chala pakati pa maziko ndi malo ogulitsira makina pamene chida chiphulika. Ku QSY, kuponya kwawo kophatikizana ndi CNC makina Kuthekera kumatanthauza kuti akuganiza za kudula komaliza panthawi yopanga nkhungu. Kuyanjanitsa kumeneku ndi kwamtengo wapatali pakuwongolera mtengo womaliza.
Aloyi Mkati mwa Aloyi: Tsatirani Zinthu Zofunika
Kutchula Inconel 718 ndi chiyambi chabe. Ndi AMS 5662? Chithunzi cha AMS5663 Kusiyana kuli m'magawo ovomerezeka a aluminiyamu, titaniyamu, ndi niobium. Zochepa za magawo khumi pa zana zimatengera kuyankha kwa ukalamba ndi mphamvu zomaliza. Mukugwiritsa ntchito mwamphamvu kwambiri, simukugula generic 718; mukugula chemistry yosungunuka ndi lipoti lotsimikizika la kutentha.
Ndikukumbukira m'malo mwa ogulitsa omwe adatsala pang'ono kuyimitsa. Gawoli lidatsimikiziridwa kuti 718, koma linali losungunuka pang'ono lomwe limapangidwa kuti lizitha kukhazikika, osati kukhazikika kwa kutentha komwe timafunikira. Inadutsa makina otenthetsera m'chipinda, koma pansi pa katundu pa 1000 ° F, chiwombankhangacho chinali chosatheka. Kusanthula kolephera kudatengera ku chiŵerengero cha Al/Ti. Tsopano, nthawi zonse timatchula ma AMS enieni kapena nambala yosungunula ndi kufuna ma cert a mphero omwe amawonetsa chemistry yeniyeni, osati kuti ndi 'mkati mwapadera'.
Mulingo wotsatirika uwu ndiwoyambira kwa wopereka aliyense wamkulu. Ndi mbali yotopetsa, zolemba-zolemetsa zogwirira ntchito maziko a nickel ma alloys omwe amalekanitsa magawo omwe amagwira ntchito ndi omwe amalephera mwakachetechete. Dongosolo labwino la foundry si gawo la admin; ndi chida chopangira.
Nthawi Yomwe Mungaigwiritse Ntchito (Ndi Nthawi Yoyenera Kuchoka)
Zabwino kwambiri maziko a nickel ntchito yomwe ndidagwiritsapo ntchito inali seti ya ma thermowell a catalytic reformer unit. Chilengedwe chinali hydrogen sulfide, high-pressure hydrogen, ndi kutentha kwa cyclic mpaka 950 ° F. Chitsulo chosapanga dzimbiri chikanachita dzimbiri kapena kusungunuka pakapita miyezi. Zitsime za Inconel 600 zidakhala zaka zambiri. Zomwe zimayenderana bwino ndi luso la alloy: dzimbiri kwambiri komanso kutentha kwambiri.
Choyipa kwambiri chinali chomangira chomangika m'malo owononga pang'ono, otenthedwa ndi kutentha. Makasitomala anali ndi 'nickel alloy' muyeso yawo yamagawo ovuta ndipo adakana kusuntha. Tinagwiritsa ntchito Aloyi 276. Zinagwira ntchito bwino, koma mtengo wake unali wosamveka. Chitsulo chosapanga dzimbiri chosapanga dzimbiri chowirikiza chikanagwira ntchitoyo pagawo limodzi mwa magawo atatu a mtengo wake. Osalora kuti mfundo zina zikhale chipembedzo. Yang'anirani malo enieni ochitira ntchito kaye.
Uku ndiye kuweruza kothandiza komwe kumabwera chifukwa chowona magawowa muutumiki. Sizongokhudza zomwe aloyi angachite; zili ngati mphamvu zake zapadera ndizofunikira pantchitoyo. Nthawi zina, kusuntha kwa akatswiri kwambiri ndikupangira zinthu zotsika mtengo, zoyenera.
Tsogolo Sikuti Ndi Ma Aloyi Atsopano Okha
Pali zomveka zambiri zokhudzana ndi zitsulo zatsopano za ufa maziko a nickel superalloys, ndipo ndi ochititsa chidwi. Koma pazinthu zambiri zamafakitale, zopindulitsa zazikuluzikulu zimakhala zodalirika komanso kapangidwe kazopangapanga. Kodi titha kupanga tchanelo chozizirira chovuta kuti chikhale choponyera kuti tipewe kuphatikiza kolimba? Kodi tingathe kusintha utali wa fillet kuti tichotse masitepe opangira makina komanso cholumikizira kupsinjika?
Kugwirizana pakati pa mapangidwe ndi kupanga kuyenera kukhala kolimba. Kutumiza chojambula chomalizidwa, chosatheka kuponyedwa ku maziko ndikupempha mawu ndi chiyambi choipa. Kuphatikizira wothandizana nawo waukadaulo ngati QSY koyambirira, pomwe mapangidwe ake akadali amadzimadzi, amawalola kuti apereke malingaliro osintha pakumveka bwino ndi makina. Zochitika zawo kudutsa chitsulo chachitsulo, zitsulo,ndi ma aloyi apadera imawapatsa chidziwitso chambiri pazomwe zimakhala zovuta kwambiri pa ntchito ya nickel base.
Pamapeto pake, kugwira ntchito bwino ndi zipangizozi ndi kulemekeza zovuta zawo popanda kuchita mantha nazo. Ndi kusakanizikana kwa sayansi yolimbikira - kuyang'ana ma cert a mphero, kulimba kwa chitsanzo - komanso pafupifupi kumverera kwaluso pansi pa sitolo, monga kudziwa phokoso lenileni lomwe chida chiyenera kupanga pamene chikudula Inconel molondola. Kusakaniza kumeneko ndi kumene kumasintha zinthu zovuta kukhala yankho lodalirika.
