Mukamva 'Haynes 25 material seal', lingaliro laposachedwa nthawi zambiri limalumphira kumphamvu yake yotentha kwambiri - moyenerera, chifukwa cha cobalt-chromium-nickel-tungsten cobalt. Koma m'zaka zanga zomwe ndikuchita ndi zigawo zolondola, ndawonapo vuto lenileni sizomwe zimapangidwira papepala; ndiko kumasulira kwa zinthuzo kukhala chosindikizira chodalirika, chosasunthika pansi pa kupsinjika kwa kutentha ndi makina. Mapepala ambiri amatsimikizira kukana kwake kwa okosijeni mpaka 1800 ° F, koma safotokozanso zamitundu yamakina kapena kusindikiza pamwamba komwe kumafunikira ntchito yapa CNC yomwe imapanga kapena kuswa ntchitoyo. Ndi chinthu chimodzi kuchiponya icho; wina kuti amalize kukhala chisindikizo chogwira.
Makhalidwe a Aloyi ndi Zowona Zamakina
Haynes 25, kapena L605, siwopanda banga. Mlingo wake wolimbikira ntchito ndi wodziwika bwino. Mukuganiza kuti mukudula lathe, ndipo mwadzidzidzi chidacho chimangolankhula kapena kuvala msanga ngati magawo anu atsekedwa pang'ono. Tinaphunzira izi movutikira kale. Pankhope yosindikizira yoti ilumikizane ndi turbine utsi, tidagwiritsa ntchito zoyika zokhazikika za carbide. Chotsatira? Kusawoneka bwino kwa pamwamba ndi ma micro-fractures m'mphepete - osavomerezeka kuti asindikize. Zomwe zimafunikira kukhazikitsidwa kolimba, zida zakuthwa zokhala ndi chowotcha chabwino, ndipo nthawi zambiri, kusinthira ku magiredi a ceramic kapena CBN kuti mumalize mapasi kuti mukwaniritse zofunikira za Ra 16 kapena kuposa.
Apa ndipamene zochitika za foundry zimakhala zovuta. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi zaka makumi atatu mu zipolopolo ndi kuponya ndalama, akumvetsa kuti khalidwe loponyera limapereka 50% ya nkhondo ya Machining. Haynes 25 yopanda kanthu yopanda kanthu yokhala ndi shrinkage yamkati kapena zophatikizika zitha kuwononga chisindikizo panthawi ya makina, ngakhale wogwiritsa ntchito CNC ali ndi luso lotani. Kuyika kwawo pazitsulo zapadera kumatanthawuza kuti akufufuza malo oyenera kapena kuwongolera chemistry yosungunuka kuti achepetse zovutazi kuyambira pachiyambi.
Kusindikiza geometry palokha kumawonjezera zigawo. Chisindikizo chosavuta cha nkhope? Mwina molunjika. Koma mukaphatikiza zinthu zovuta monga ma groove-bancing grooves kapena anti-rotation slots molunjika mu gawo la Haynes 25, makina opanga makinawa amayenera kuyankha chifukwa cha chizolowezi cha alloy. Tidayenera kusintha ma clamping ndi machitidwe kuti tipewe kusokoneza nkhope yosindikiza. Ndi njira yogwira mtima, osati yongopangidwa.
Mapangidwe a Zisindikizo ndi Zovuta Zogwiritsa Ntchito
Kupanga msonkhano wosindikizira kuzungulira Haynes 25 ndi gawo lina. Kukula kwake kwamafuta kumasiyana kwambiri ndi zida zokwerera wamba monga Inconel kapena zitsulo zina. Mu chisindikizo chosasunthika cha valve yotentha kwambiri, nthawi ina tinagwirizanitsa mpando wa Haynes 25 ndi tsinde la alloy. M'nyengo yozizira, kutentha kwapang'onopang'ono kumapangitsa kuti pakhale njira yowonongeka. Kodi tikuphunzirapo chiyani? Chisindikizo sichimangokhala gawo la Haynes; ndi dongosolo lonse la zinthu. Muyenera kutengera kukula kwa matenthedwe kapena, bwino apo, yesani pamikhalidwe yoyeserera.
Thandizo lapamtunda ndi nkhani yotsutsana. Ena amalumbirira ndi plating ya chrome yopepuka kapena njira yapadera ya nitriding kuti alimbikitse kukana kwa nkhope yosindikiza. Komabe, ndi Haynes 25's chromium oxide wosanjikiza wopangidwa ndi kutentha, kuwonjezera zokutira kwina nthawi zina kumatha kuphulika kapena kutsika, ndikupanga zinyalala zomwe zimakwera pamwamba. Muzinthu zovuta kwambiri zomwe timagwiritsa ntchito - kuganiza zamlengalenga kapena zida zothandizira zopangira magetsi - zokonda zimatsamira pazitsulo zopangidwa mwaluso komanso zopukutidwa. Kukhulupirika kwa gawo lachilengedwe la oxide ndikofunika kwambiri.
Kusanthula kulephera nthawi zambiri kumawonetsa ntchito zachiwiri. Chisindikizo cha chisindikizo chikhoza kuyesa mayesero, koma kulephera kugwira ntchito chifukwa cha kuwonongeka kwa kasamalidwe. Haynes 25, ngakhale atakhala wolimba, amatha kukopeka. Tidakhazikitsa ma protocol okhwima a post-machining pogwiritsira ntchito zida zopanda zitsulo komanso zoteteza m'mphepete, makamaka titaona kuti zisindikizo zingapo zabwino zimakanidwa chifukwa cha ma burrs omwe amayambitsidwa poyeretsa pamanja. Ndizinthu zamba zomwe zimalekanitsa chisindikizo chogwira ntchito kuchokera ku chodalirika.
Case in Point: Chisindikizo cha Turbine Bypass Valve
Chitsanzo cha konkire chinali pulojekiti yobwezeretsanso makina opangira mpweya wapamtunda. Chisindikizo choyambirira mu choyimitsa valavu chodutsa chinali kulephera msanga chifukwa cha kuphatikizika kwa kutopa kwambiri komanso kutsika kwamafuta. Wogulayo adatchula Haynes 25 kuti alowe m'malo. Vutoli linali gawo lopyapyala la gawolo pafupi ndi milomo yotseka, yomwe imakonda kusokonekera panthawi yolumikizira njira yomwe imafunikira pambuyo popanga makina kuti achepetse kupsinjika.
Njira yathu, yopangidwa ndi kuyesa ndi zolakwika, idakhudza kukonza movutikira, njira yochepetsera kupsinjika, kenako kumaliza kupanga ndikuchotsa kochepa. Kulimbitsidwa komaliza kwa cone yosindikiza ya digirii 45 kunachitika pamwambo. Tidagwirizana kwambiri ndi makina opanga makina ku Mtengo wa QSY pa izi, kugwiritsa ntchito kwawo CNC makina ukatswiri wa zovuta zamkati zamkati. Kukhoza kwawo kulekerera zolimba pa fomu yopangira ndalama zinali mwayi waukulu, kuchepetsa nthawi yathu yomaliza yopangira makina komanso chiwopsezo.
Kupambanako kudadalira kuwongolera kapangidwe kambewu. Njere yolimba yochokera ku njira yopangira kutentha kosayenera imachepetsa kutopa kwapang'onopang'ono, ngakhale kuuma kwake kunali kolondola. Tidamaliza kunena za momwe ng'anjo imalamuliridwa kwambiri panthawi yotentha yomaliza kuti tipewe kuwonongeka kulikonse kapena kuwonongeka kwamoto, komwe kukanasokoneza mawonekedwe a chisindikizocho. Gawoli lakhala likugwira ntchito kwa miyezi yopitilira 18 tsopano popanda zovuta zomwe zanenedwa - kupambana pang'ono komwe kunatsimikizira njirayo.
Zolakwika Zamakampani ndi Supplier Synergy
Lingaliro lolakwika lodziwika bwino ndikuti kuponya 'super alloy' ngati Haynes 25 pavuto losindikiza kumangothetsa. Osati zoona. Ndawonapo zisindikizo zopangidwa mopitilira muyeso pomwe cholumikizira chosavuta, chotsika mtengo chokhala ndi zokutira zoyenera bwino chikadachita mokwanira. Kulungamitsidwa kwa Haynes 25 kuyenera kukhala kuphatikiza kowoneka bwino kwa mpweya wa okosijeni, kutentha kopitilira 1500 ° F, ndikufunika mphamvu zamapangidwe. Apo ayi, mukungowotcha bajeti.
Ichi ndichifukwa chake kuyanjana ndi ogulitsa omwe amamvetsetsa ulendo wonse kuchokera kusungunuka kupita ku makina ndikofunikira. A luso foundry ndi makina monga Mtengo wa QSY si wogulitsa chabe; iwo ndi gwero. Mukakambirana a Haynes 25 chisindikizo chakuthupi pulojekiti ndi iwo, zokambirana zitha kufalikira kuchokera ku njira yabwino yoponyera (yawo chipolopolo nkhungu kuponyera zitha kukhala zabwinoko kwa ma geometries ena kuposa kuyika ndalama pa aloyiyi) kuti mutumize zofunikira za NDT, mpaka pokonzekera ma CNC ops omaliza. Kupitilira kumeneko kumachepetsa mipata ya chidziwitso yomwe imabweretsa kulephera kwamunda.
Mfundo ina yothandiza ndi nthawi yotsogolera komanso kufufuza zinthu. Genuine Haynes 25 sakhala pa alumali nthawi zonse. Wopereka ndi ntchito kwa nthawi yayitali mu ma aloyi apadera nthawi zambiri amakhazikitsa ma chain chain a stock certified stock. Pazisindikizo zovuta, mumafunika ma cert athunthu a mphero, ndipo nthawi zambiri, kutsimikizika kowonjezera kwa chemistry. Awa si malo oti mudule ndi zinthu zosatsimikizika 'zofanana', chifukwa kusindikiza kumalumikizidwa mwachindunji ndi kapangidwe ka aloyi.
Malingaliro Omaliza: Ndi Zokhudza Njirayi
Ndiye, nchiyani chimapangitsa chisindikizo chopambana cha Haynes 25? Nthawi zambiri si nthawi imodzi ya eureka. Ndiko kuphatikizika kwa kusankha koyenera kwa zinthu, kuwerengera kodziwitsa za kachitidwe katenthedwe, makina olondola komanso odziwa zambiri, komanso kusamalira mosamala. Zinthuzo ndizokhoza, koma sizokhululukira njira zazifupi.
Makampani akusintha kwa ogulitsa ophatikizika-omwe amatha kuponyera, kutentha kutentha, ndi makina pansi padenga limodzi-ndizomveka pazinthu zotere. Imalimbitsa malupu obwereza. Ngati nkhope yosindikiza ikuwonetsa kusokonezeka pakuwunika komaliza, katswiri wamakina amatha kukaonana ndi metallurgist yemwe amayang'anira chithandizo cha kutentha, komanso injiniya wopeza yemwe adapanga njira yolowera. Kuthetsa mavutowa ndikofunika kwambiri.
Pamapeto pake, mawu ofunikira ndi 'umphumphu' - kukhulupirika kwazitsulo kwa gawo la Haynes 25 komanso kukhulupirika kwazomwe amapanga. Zonse zikagwirizana, mumapeza chisindikizo chomwe sichimangokumana ndi pepala, koma chimagwira ntchito molimba mtima, yonjenjemera, yothamanga panjinga yamafakitale. Ndicho cholinga chenicheni, ndipo chimakwaniritsidwa mwatsatanetsatane wa msonkhano, osati pa kabuku ka malonda.
