Aliyense amalankhula za Inconel 625 ngati kuti ndi chipolopolo chamatsenga cha kutentha kwambiri. Ndi, makamaka. Koma ngati mwazipangadi, kuzikulunga, kapena kuziyikamo, mukudziwa kuti matsenga amabwera ndi msonkho waukulu. Sikuti 'super alloy'; ndi kudzipereka.
The Hype vs. The Lathe
Mukuwona pepala lodziwika bwino: kukana kwa okosijeni kosangalatsa mpaka 1800 ° F, mphamvu yayikulu, yadda yadda. Chimene sali mutu wamutu ndi momwe zimagwirira ntchito. Mumatenga chida chokongola, chakuthwa ndikudulapo Mtengo wa 625, khalani ndi chip chabwino, ndipo mwadzidzidzi simukudulanso - mukungopaka ndi kutulutsa kutentha kokwanira kuti chida chanu chifewetse, osati chogwirira ntchito. Pamwamba pamakhala molimba kuposa momwe mudayambira. Ndawona mayendedwe omwe adagwira ntchito bwino pa 316L akungowonongeka. Mufunika makina olimba, ma geometries abwino, komanso minyewa kuti muziyenda pang'onopang'ono ndi chakudya cholemera komanso chosasinthasintha. Kukayika ndi imfa.
Kuziziritsa sikochita kusankha, ndi njira. Mufunika kuthamanga kwambiri kuti mufike pamphepete kuti muthyole chotchinga cha kutentha ndikutsuka tchipisi. Ngati tchipisi tibwereranso, ndiye kuti masewerawa atha ndi chida. Ndimakumbukira ntchito yomwe tinali kukonza gulu lalikulu la valve kuchokera ku Mtengo wa 625 kuponyera. Tinkaganiza kuti tayiyitanira, koma pamapeto omaliza otopetsa, tinthu tating'onoting'ono tidakulungidwa pa bala. Idasiya chiwopsezo pa ID kotero kuti tidasiya gawolo. Phunziro la $ 20,000 pakuwongolera chip.
Komanso fufuzani zinthu za masheya kapena zoponya. Sikuti onse 625 amapangidwa mofanana. Mchitidwe wosungunula, kapangidwe ka tirigu - zimakhudza kwambiri maginito. Kuponyera porous kumawononga zida mwachangu kuposa momwe munganenere kalasi. Mufunika wogulitsa yemwe amamvetsetsa izi kuyambira poyambira, osati nyumba yosungiramo katundu yokhala ndi macheka.
Kuwotcherera: Kumene Mayeso a Chemistry Amachitika
Kuwotcherera Mtengo wa 625 ndizochepa za kujowina komanso zambiri za kusunga katundu wake. Mdani wamkulu ndi mpweya wa carbide m'dera lomwe lakhudzidwa ndi kutentha (HAZ). Mumatentha kwambiri kwa nthawi yayitali, ndipo ma chromium carbides amapanga m'malire a tirigu. Mwadzidzidzi, chinthu chanu chodabwitsa chomwe sichimadwala chimakhala ndi kanjira kakang'ono kowukira pafupi ndi chowotcherera. Zikuwoneka bwino, koma sizigwira ntchito.
Muyenera kuwongolera mwamphamvu pakulowetsa kutentha. Mikanda yotsika, mikanda yolimba, zoyima zambiri kuti izizizire. Ndipo muyenera kugwiritsa ntchito chodzaza choyenera-kawirikawiri zitsulo zodzaza 625 zokha kapena nthawi zina ERNiCrMo-3. Kugwiritsa ntchito zodzaza zosapanga dzimbiri chifukwa ndizothandiza ndikulephera kotsimikizika. Ndawonapo ntchito zokonza pamapampu pomwe wina adachita zomwezo. Chowotchereracho chinali ndi mphamvu, koma chinasweka chifukwa cha chloride stress corrosion m'miyezi isanu ndi umodzi. The post-mortem inasonyeza mzere wolimba kumene chemistry inasintha.
Kuyeretsa kusanachitike komanso pambuyo pa kuwotcherera ndikwachipembedzo. Palibe mafuta, palibe sulfure, palibe kanthu. Kuipitsidwa kulikonse kumalowetsedwa mu weld dziwe ndikupanga magawo osalimba. Ndi mulingo waukhondo womwe umamva ngati wachitidwa opaleshoni.
The Casting Conundrum
Kutulutsa phokoso mkati Mtengo wa 625 ndi luso. Aloyiyo imakhala ndi kuzizira kwautali, zomwe zimapangitsa kuti zisawonongeke komanso kung'ambika kotentha ngati khomo ndi kukwera sikuli bwino. Simungangothira ngati chitsulo chachitsulo. Choyambira chiyenera kuwongolera kutentha kwa nkhungu, kuchuluka kwa kuthirira, chilichonse.
Apa ndi pamene zochitika pazaka zambiri zimakhala zofunikira. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka zawo 30 zachipolopolo ndi kupanga ndalama, zikanapanga chidziwitso chenichenicho. Amadziwa kuwongolera nyumba ya turbine mu nkhungu kuti muchepetse kupsinjika, kapena kupanga dongosolo la chakudya chamtundu wokhuthala wosinthira kukhala khoma lopyapyala. Ndi chidziwitso cha mafuko omwe simungapeze kuchokera m'mabuku.
Mbiri yawo mu zitsulo zopangidwa ndi nickel ndi CNC Machining ndiye chinsinsi. Iwo sakungopanga mawonekedwe; akuganiza momwe gawo lomaliza lidzawunikiridwa ndi kuwotcherera. Kodi amasiya katundu wokwanira pa nkhope zovuta? Kodi amayika mzere wolekanitsa kuti achepetse kumaliza ntchito pamalo osindikizira? Malingaliro ophatikizika amenewo amapulumutsa ndalama zambiri pansi.
Nthawi Yomwe Mungaigwiritse Ntchito (Ndi Nthawi Yoyenera Kuchoka)
Ndiye ndi mutu wonsewu, mugwiritse ntchito bwanji? Zosavuta: pamene palibe china chomwe chimapulumuka. Malo okhala m'madzi am'nyanja okhala ndi chloride wambiri. Flue gasi desulfurization systems. Zomangira zotentha kwambiri zokhala ndi gasi wowawasa. Ndiwokhazikika pamagawo ovuta, osasuntha pamakina amphamvu a chem/petrochemical.
Koma ndabwerera m'mbuyo pa zowunikira. Wofuna chithandizo ankafuna zonse Mtengo wa 625 zambiri za utumiki wochepa wa asidi organic pa 300 ° F. Ndizo overkill. Tidasanthula mtengo wa moyo wonse ndikuyerekeza ndi ma duplex apamwamba kwambiri. Duplex idapambana pamtengo woyambira, mtengo wopangira, ndipo ikadatha zaka 20 zopanga. Nthawi zina mainjiniya amatchula 625 chifukwa ili pamndandanda wazinthu zosagwira dzimbiri, osati chifukwa ndizosankha zachuma. Chimodzi mwa ntchito ndi kudziwa nthawi yoti mutsike.
Mphindi ina yochokapo ndi pamene mapangidwe ake ali ndi ngodya zakuthwa kapena amafunikira makina ovuta kwambiri, ozama. Zopsyinjika zomwe mumayambitsa zingakhale zosafunikira. Nthawi zina, kukonzanso chigawocho kuti chikhale chosavuta kupanga ndikwanzeru kuposa kulimbana ndi zinthuzo.
The Real-World Supply Chain
Simumangoyitanitsa Inconel 625. Mukuyenerera gwero. Kwa castings, mukuyang'ana maziko omwe angapereke cert zakuthupi zomwe zimayambira kutentha, zokhala ndi chemistry ndi makina. Mutha kutchulanso ndondomeko yanu yochizira kutentha—kusungunula pa 2150°F ±25°F kutsatiridwa ndi kuzimitsa mwachangu ndi muyezo wosungunula ma carbides owopsawo.
Kwa mnzanu wantchito yonse, mukufuna munthu amene amayang'anira ulendo wonse. Kuyang'ana kuchuluka kwa QSY-kuchokera pakuyika ndalama za ma aloyi apadera mpaka makina omaliza a CNC-omwe amathetsa kuloza zala zambiri. Ngati pali cholakwika chopezeka pakupanga makina, ndiye kuti alithetse, osati mkangano pakati pa maziko ndi malo ogulitsira makina. Kupitilira kumeneko ndi kwakukulu kwa magawo ovuta, amtengo wapatali.
Nthawi yotsogolera ndi yaitali. Zinthu zabwino sizikhala pa alumali. Kuthekera kwabwino kumasungidwa. Aliyense amene akulonjeza kuti asintha mwachangu akudula ngodya, motsimikizika. Konzekerani kwa miyezi, osati masabata.
Pomaliza, Mtengo wa 625 ndi chinthu chodabwitsa chomwe chimafuna ulemu. Si chinthu chofunika; ndi mgwirizano pakati pa wopanga, wopanga zitsulo, woyambitsa, ndi wamakina. Konzani unyolowo bwino, ndipo mupeza chinthu chomwe chimapitilira mbewu yomwe idayikidwamo. Muphonye ulalo, ndipo mumapeza pepala lolemera kwambiri. Kusiyana kuli mwatsatanetsatane, mwatsatanetsatane momwe amapangidwira.
