Mukamva N06625, kapena Inconel 625 monga momwe anthu ambiri ogulitsa amatchulira, chinthu choyamba chomwe chimabwera m'maganizo nthawi zambiri chimakhala 'kutentha kwambiri' kapena 'kusagwirizana ndi dzimbiri'. Ndiwo msampha wamba. Ndikochulukira kwambiri kuposa pamenepo. Ndawonapo ma projekiti akuyimitsidwa chifukwa wina adazifotokoza akuganiza kuti ndi chinthu chamtundu umodzi pazachiwopsezo chilichonse. Si. Nkhani yeniyeni ili mu khalidwe lake panthawi yopangira komanso pansi pazikhalidwe zinazake zautumiki, osati pa datasheet. Mdierekezi, monga nthawi zonse, ali mu tsatanetsatane wa ntchito yake.
The Fabrication Reality Check
Tiyeni tikambirane Machining. Aliyense amene amayendetsa lathe kapena mphero pa 625 amadziwa mawu oti 'oh, izi zikuyenda bwino' zimapatsa ulemu. Zimagwira ntchito-zimawumitsa. Mofulumira. Ngati simukupeza ma feed ndi liwiro lanu kuyambira pomwe mukupita, sikuti mukungotaya choyikapo; mukupanga pamwamba kwambiri kuti chiphaso chotsatira chimakhala chovuta. Ndidaphunzira izi movutirapo, ndikuyesera kudula pang'onopang'ono pa shaft yomwe idatembenuzidwa kuti ndigwiritse ntchito skate ndikuwotcha pamwamba. Gawolo linali lachikale. Mufunika kukhazikika kolimba, ma geometries abwino, ndi kuwongolera kuti chida chikhale chokhazikika komanso chodula, osati kusisita. Zoziziritsa? Sefukirani. Osati zokometsera kwambiri mpaka kukokera kutentha kutali ndi malo odulidwa kuti muchepetse kuwumitsa.
Apa ndipamene kuyanjana ndi sitolo yomwe ili ndi mtunda weniweni pazinthu izi kumapanga kusiyana. Ndawunikanso ntchito kuchokera kumalo ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd.. Kuganizira kwawo kwa nthawi yayitali CNC makina ma aloyi apadera si chipolopolo chabe. Mutha kuziwona m'mapepala awo - amalowa mwatsatanetsatane wa njira zopangira zida zitsulo zopangidwa ndi nickel kusamalira kutentha ndi kupsinjika, zomwe ndizomwe 625 imafuna. Ndikumvetsetsa kothandiza komwe kumabwera popanga magawo, osati kungowatchula.
Ndiye pali kuwotcherera. Gawo la laves. Ndiye wowotcherera 625. Kutentha kochuluka kwambiri, kapena zodzaza zosayenera, ndipo mumapeza ma brittle intermetallic compounds mu weld zone. Ndimakumbukira phokoso la chotengera choponderezedwa pomwe chowotcherera chidadutsa zowoneka ndi X-ray koma zidalephera pakuyesa kupsinjika. Microanalysis inawonetsa kupanga laves. Kukonza sikunali kungosintha magawo; idasintha kukhala zitsulo zodzaza bwino kuti zithetse mapangidwewo, monga 625 Plus. Zinawonjezera mtengo, koma kunali kusiyana pakati pa kukonza ndi kulephera m'munda. Izi zikukuphunzitsani kuti kuyeneretsedwa si mwambo; ndiye maziko a umphumphu.
Beyond Corrosion: Kukhazikika kwa Magwiridwe
Inde, ndizowoneka bwino m'malo oxidizing. Koma ntchito yake ya nyenyezi, m'malingaliro mwanga, ili pakukana kwa chloride-ion stress-corrosion cracking (SCC). Tidagwiritsa ntchito popanga mapampu amadzi amchere pomwe 316L ikadasweka pakanthawi. Koma apa pali kusiyana kwake: kukana kumeneko sikungatheke. Ndawonapo kuyambika kwa pitting pansi pazikhalidwe zoyipitsitsa pomwe ma chloride amakhazikika. The alloy anakana mng'alu, koma ife tidakumanabe kuukira. Kodi tikuphunzirapo chiyani? Kusankha kwazinthu ndi njira yopangira dongosolo. Mukuyenerabe kuganizira za kuyenda, kuyeretsa mwayi, ndikugwirizanitsa ndi zipangizo zosindikizira zoyenera.
Mphamvu yake yotentha kwambiri ndi gawo lina la malingaliro olakwika pang'ono. Anthu amayang'ana manambala amphamvu a 1000 ° F+ ndikuganiza kuti ndi a zigawo zotentha m'ma turbines. Ngakhale imagwiritsidwa ntchito pamenepo, kagawo kakang'ono kake kamakhala kagawo kapakati - titi, makina otulutsa mpweya kapena zopangira kutentha - komwe mumafunikira mphamvu zokwawa bwino komanso kukana kwa okosijeni kodabwitsa. Zomwe zili mu chromium zimakhala zokhazikika, zoteteza. Tinkagwiritsa ntchito ngati machubu owala mung'anjo yoyaka moto. Anawonjezera zinthu zam'mbuyomo ndi katatu, osati chifukwa chakuti anali amphamvu pa kutentha, koma chifukwa chakuti sanakule ndi kuchepetsa. Njira yolephereka idasintha kuchoka pakuwonda pang'onopang'ono mpaka kutopa kwakanthawi kochepa pakatha zaka zambiri.
Izi zikugwirizana ndi mbali ya maziko. Makhalidwe oponya a N06625 ndi… makamaka. Imakonda kukhala ndi microporosity ndi tsankho ngati kutentha kwa kutentha ndi nkhungu sikuyendetsedwa mwamphamvu. Sitolo yomwe imapanga ndalama kapena chipolopolo nkhungu kuponyera ndi aloyi izi bwinobwino si kuthira zitsulo; iwo akuwongolera sewero la kutentha kuchokera ku ng'anjo kupita ku shakeout. The Mtengo wa QSY Webusayiti imatchula ntchito yawo ndi ma aloyi apadera, zomwe zimaphatikizansopo gawo ili la kayendetsedwe ka kayendetsedwe kake. Mukamagula chigawo cha 625, mukuguladi protocol yotentha ya foundry.
Supply Chain ndi Formability Quirk
Kupeza 625 bar kapena mbale ndikosavuta pano kuposa zaka khumi zapitazo, koma muyenera kuyang'ana mphero ngati kabawi. Osati za chemistry, komanso mbiri yotentha komanso yocheperako. Tidalandirapo mbale yomwe idakumana ndi zolemba za AMS ndi ASTM pamapepala koma idawonetsa kusiyanasiyana kwamachitidwe ake kutalika kwake. Kufufuza kunasonyeza kuti mpheroyo inali yosagwirizana, zomwe zinachititsa kuti madera ena akhale olimba, ocheperapo. Mpheroyo idakonza bwino, koma zidatiwonongera sabata imodzi. Tsopano, sitimangotchula mulingo wokha, koma nthawi zambiri njira ina yosinthira kapena wopanga yemwe amakonda kwambiri pazofunikira.
Kuupanga kuzizira ndi chimbalangondo. Ili ndi high springback. Ngati mukuipinda, mukuipinda kwambiri pa chida ndikuyembekeza kuti ibwereranso. Kwa mawonekedwe ovuta, kupanga kutentha nthawi zambiri ndiko njira yokhayo yanzeru. Tinapanga mavuvu amtundu wina wokulitsa kuchokera papepala lopyapyala. Kuyesera koyamba kuzizira-ntchito zakuthupi kotero kuti zidataya ductility ndikusweka panthawi ya hydrotesting. Yankho lake linali kupanga pafupifupi 1200 ° F, zomwe zimafunikira zida zapadera ndi kuwongolera mpweya kuti mupewe okosijeni wambiri. Unali nkhani yachikale ya zinthu zomwe zimalamulira njira yonse yopangira.
Ichi ndichifukwa chake chitsanzo cha utumiki wathunthu cha ena ogulitsa ndi ofunika. Ngati gwero limodzi, monga tatchulazi Mtengo wa QSY, akhoza kusamalira kuponya ndalama kuti mupange mawonekedwe apafupi ndi ukonde ndikutsata ndendende CNC makina pa aloyi yemweyo, amachotsa zoopsa zambiri zogwirira ntchito, zovomerezeka, komanso zowunikira. Simukutumiza zopangira makina opangira makina omwe mwina sangamvetse zovuta zake. Chidziwitsocho chimakhala mu chilengedwe chimodzi.
Mtengo motsutsana ndi Mtengo: Kuwerengera Kweniyeni
Tinene mosabisa: N06625 ndi okwera mtengo. Ma nickel ndi niobium amawona izi. Kulungamitsidwa sikumabwera chifukwa chokhala 'chabwino kukhala' kapena 'premium.' Zimachokera ku kusanthula kwathunthu kwa umwini komwe kumaphatikizapo nthawi yopuma, ntchito yowonjezera, ndi chitetezo. Tinalowa m'malo mwa carbon steel quench tank agitator shaft ndi imodzi yopangidwa kuchokera ku 625. Chitsulocho chinatenga miyezi 8 mu caustic, malo odzaza ndi kloridi. 625 shaft ikugwirabe ntchito patatha zaka 7. Mtengo wakutsogolo unali 5x, koma kupewa kuzimitsa kasanu kuti m'malo mwake kudalipira m'miyezi 18. Mtengo uli mu ntchito yosalekeza, osati mtengo woyambira.
Komabe, muyenera kusamala kuti musagwiritse ntchito mopitirira muyeso. Si nthawi zonse yankho. Kwa malo owononga pang'ono pomwe 2205 duplex zitsulo zosapanga dzimbiri zitha kukhala zokwanira, kugwiritsa ntchito 625 ndikolakwika kwachuma komanso nthawi zina luso. Duplex ili ndi mphamvu zambiri, kotero mutha kugwiritsa ntchito zochepa, ndipo nthawi zambiri imakhala yosavuta kuwotcherera. Chosankhacho chimafuna kuwunikiranso mosasamala za mawonekedwe enieni a mankhwala, kutentha, kupsinjika, komanso moyo womwe mukufuna. Ndakhala gawo la magawo a uinjiniya wamtengo wapatali pomwe tidakangana bwino kuti titsike kuchoka pa 625 kupita ku super duplex, kupulumutsa 30% pamtengo wamtengo wapatali popanda kutayika kwa ntchito pa mlandu womwewo.
Izi zimabwereranso ku ukatswiri wa wopanga. Wokondedwa wabwino samangoti 'inde' kuzinthu zakuthupi. Iwo amazifunsa izo. Atha kuyang'ana chithunzi cha 625 gawo ndikufunsa kuti, 'Mukuwona chiyani? Kodi mwaganizirapo za X pa gawoli?' Kukambitsirana kumeneko, kobadwa kuchokera ku zochitika zamanja ndi kupambana ndi kulephera kwa zipangizozi, ndi kumene umisiri weniweni umachitika. Ndi kusiyana pakati pa kugula chitsulo ndi kupanga njira yothetsera.
Kumaliza Popanda Uta Pa izo
Chifukwa chake, N06625. Ndi kavalo, koma wokwiya. Mtengo wake si wachibadwidwe; zimazindikirika kokha mwa kupeka molondola, mwachidziwitso komanso kugwiritsa ntchito moyenera. Mapepala a deta amakupatsani malire, koma chidziwitso cha momwe chimayendera pansi pa chida, momwe chimathamangira mu nkhungu, momwe chimachitira pansi pa nyali - ndicho luso. Ndicho chimene chimalekanitsa chigawo chogwira ntchito kuchokera ku chodalirika.
Mukayang'ana ogulitsa, luso limenelo ndiye metric wofunikira. Kodi angakambirane zovuta za kutentha kwa interpass pa chowotcherera chamitundu yambiri? Kodi ali ndi njira zolembedwa zochepetsera kuuma kwa ntchito panthawi ya makina? Pazigawo zotayidwa, kodi zikuwonetsa kuwongolera kwanyengo yonse yosungunuka yosungunuka? Izi ndi zizindikiro zowoneka za luso.
Pamapeto pake, kugwira ntchito ndi alloy iyi ndi njira yophunzirira mosalekeza. Pulojekiti iliyonse imawonjezera mfundo. Kuthamanga bwino kumakuphunzitsani zomwe zimagwira ntchito. Kulephera, komwe nthawi zambiri kumakhala mphunzitsi wamphamvu, kumakuwonetsani komwe kuli malire obisika. Cholinga ndikumanga laibulale yamkati yachidziwitsocho, kotero nthawi ina N06625 ikadzafika pa desiki, kuweruza kwanu momwe mungagwiritsire ntchito ndikuigwiritsa ntchito kumangokhala akuthwa pang'ono, okhazikika, komanso ogwira mtima. Ndiwo maziko enieni a akatswiri ndi zinthu izi.
