Pamene mainjiniya afotokoza Aloyi 21 kwa mavavu othamanga kwambiri a hydraulic kapena mapampu olimbana ndi dzimbiri, samangosankha chinthu - akubetcha pa kukhazikika kwa dimensional, microstructural consistency, ndi zero batch-to-batch drift mu mphamvu zokolola. Ichi ndichifukwa chake kufufuza kuchokera ku zenizeni Aloyi 21 fakitale zofunika kwambiri kuposa kale. Osati zopezeka zonse zomwe zimatha kupirira ± 0.02 mm pa 350 mm cobalt-nickel casting ndikusunga kapangidwe kambewu ka AMS 5387 pambuyo pochiritsa kutentha. Tawona mapulojekiti ambiri akuchedwa ndi ogulitsa omwe amatenga Aloyi 21 ngati "chitsulo cha nickel alloy" - kenaka amalimbana ndi macheza a makina, kusweka kosayembekezereka kwa intergranular panthawi yopuma kupsinjika, kapena kutha kwa pamwamba komwe kumalephera kutsimikizira kutsitsi kwa mchere.
Chifukwa chiyani Aloyi 21 Imafunika Kuposa Kutha Kwa Nickel Aloyi Wamba
Aloyi 21 (UNS N02021) si ntchito yachibadwa monga Inconel 600. Zomwe zili ndi 20% molybdenum zimapereka kukana kwapadera kuchepetsa ma acid - komanso zimapangitsa kuti zikhale zovuta kwambiri kuponya mwaukhondo ndi makina popanda kuuma kwa ntchito. Mu shopu yathu, tataya magulu atatu oyeserera a silinda ya pampu ya piston tisanakonzekere kutulutsa mpweya wa nkhungu yamchenga ndi kuthamanga kwa preheat. Zochitika zenizeni padziko lapansi zikuwonetsa: ngati wopereka wanu sanagwiritse ntchito zosachepera 15 zopangira zida za Alloy 21 pansi pa ISO 9001 traceability, yembekezerani kusuntha kopitilira muyeso wa GD&T - makamaka pazigawo zopyapyala zochepera 4 mm.
Timayesa mabilu a Alloy 21 omwe akubwera pogwiritsa ntchito spark-OES ndikutsimikizira kukula kwambewu pa ASTM E112. Chifukwa chiyani? Chifukwa lipoti losayenderana la kasitomala wina lidawonetsa kutentha kumodzi komwe kumakhala ndi njere zolimba - kuyambira nthawi yomwe ng'anjo imanyowa nthawi yayitali pamphero. Gulu limenelo linapambana chemistry koma linalephera moyo wotopa pakuyesa kumunda. A zoona Aloyi 21 fakitale sichimangovomereza ma certs - imatsimikizira zitsulo pakhomo.
Mphamvu Zinayi Zosakambirana Zomwe Muyenera Kuzitsimikizira
Musanasaine NDA kapena kugawana zojambula zanu za GD&T, funsani mafunso awa - ndipo funsani umboni:
- Kodi mumaponya Alloy 21 m'nyumba - kapena kusungunuka kwakunja? Kusungunula kwapanyumba komwe kumatulutsa kumayambitsa kusiyanasiyana kwa kuchuluka kwa kuphatikiza komanso zomwe zili ndi gasi. Timasungunula ndikutsanulira Aloyi 21 m'malo athu a vacuum-arc remelt (VAR) kuti tiwongolere kuchuluka kwa okosijeni pansi pa 12 ppm.
- Kodi makina anu a CNC angagwire mphero yonse ya Aloyi 21 yowuma pa 45 HRC? Zida zamtundu wa carbide zimapatuka. Timagwiritsa ntchito mphero zokhala ndi nsonga za ceramic zokhala ndi zopota zolimba za hydrostatic - ndikuwunika mavalidwe a zida pogwiritsa ntchito masensa a nthawi yeniyeni.
- Kodi mumapanga njira yothetsera kukalamba ndi kukalamba m'nyumba - ndi ma thermocouples otsimikizika ndi ng'anjo zowongoleredwa? Mphamvu za Alloy 21 zimatengera matenthedwe enieni. Digiri imodzi yotsika paukalamba imasinthira mphamvu yokhazikika mpaka 80 MPa.
- Kodi gawo lililonse limapatsidwa ID yapadera - yowoneka bwino pakutentha kwazinthu, tsiku loponyedwa, kusintha kwa makina, ndi lipoti la CMM? Kwa matupi amafuta ndi gasi, izi sizosankha. Imafunika ndi API 6A Annex F.
Zomwe Zimachitika Mukadumpha Fakitale Yapadera
Ogula ena amayesa kupulumutsa ndalama poyendetsa magawo a Alloy 21 kupita ku malo ogulitsa ntchito. Chotsatira? Mitundu itatu yolephera yomwe timatsata timatsata makasitomala 42:
- Micro-cracking m'madera omwe akhudzidwa ndi kutentha - chifukwa cha kuwongolera kutentha kwa interpass panthawi ya TIG kuwotcherera kwa ma flanges a Aloyi 21;
- Kusakhazikika kwa Dimensional pambuyo pakukonza komaliza - chifukwa chotsalira kupsyinjika kumasulidwa m'zigawo zomwe sizinachepetse nkhawa musanamalize;
- Kuyika pamwamba pa malo a chloride - kutsatiridwa ndi kuchepa kwa chromium komwe kumabwera kuchokera kukupera mwamphamvu popanda kungokhala.
Tidakonza zonse zitatu - koma titagulitsa zida zodzipatulira za Alloy 21, mavuni ochepetsa kupsinjika pang'onopang'ono, ndi malo osambira a citric-acid passivation ovomerezeka pa ASTM A967. Zomangamanga zimenezo sizotsika mtengo. Koma ndizotsika mtengo kuposa kuyika ma roller 17 a winch center shaft pakati pachombo chothandizira chakunyanja.
Kumanga Kudalirika, Kutentha Kumodzi Pamodzi
Kudalirika kumayamba chip choyamba chisanawuluke. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Dongosolo lililonse la Aloyi 21 limayamba ndikuwunikanso zomwe mukufuna - osati miyeso yokha. Timafunsa kuti: Kodi kupanikizika kwakukulu kwa ntchito ndi chiyani? Ndi ntchito yotani yomwe ikuyembekezeka? Kodi izi ziwona kukwera kwa matenthedwe a cyclic? Mawuwa amatsimikizira ngati tikulimbikitsa kupanga mchenga + kumaliza kukonza kapena kuyika ndalama + kuchotsa zinthu zochepa.
Nthawi yathu yotsogola ya maoda apakati a Alloy 21 ndi masabata 12 - osati chifukwa tikuchedwa, koma chifukwa timakonza zotentha m'mabolodi asanu ndi limodzi kuti titsimikizire mbiri yamafuta osasinthika. Sitithamangira Aloyi 21. Timalemekeza. Ndipo pamene valavu yanu iyenera kupulumuka maulendo a 15,000 pa 3,000 psi popanda kutayikira, chilangocho chimakhala malire anu a chitetezo.
Ngati mukufuna zida zolondola za Alloy 21 zomwe zimapangidwira kuti zigwire ntchito - osati kungoyerekeza - yambani ndi fakitale yomwe imagwiritsa ntchito zitsulo monga uinjiniya, osati mayendedwe. Ndicho chimene chimatanthawuza chenicheni Aloyi 21 fakitale.
