Magawo 400 a aloyi amapereka kukana kwa dzimbiri kosayerekezeka m'mafakitale ankhanza, am'madzi, komanso ma chloride apamwamba kwambiri, makamaka komwe zitsulo zosapanga dzimbiri zimalephera. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tapanga zida zopitilira 12,000 za Aloyi 400 kuyambira 2018 za matupi a hydraulic valve, nyumba zapampopi zakunyanja, ndi makina opangira mpweya wowawasa. Gawo lirilonse limayamba ndi ASTM B164-certified billet, imakumana ndi kupsinjika-kuchepetsa kupsinjika CNC isanatembenuke, ndikumaliza ndi Ra ≤0.8 μm pamwamba kukhulupirika-palibe kuchotserapo.
Chifukwa Chake Magawo a Alloy 400 Amaposa Njira Zina mu Real-World Service
Makasitomala amafunsa kuti: "Bwanji osangogwiritsa ntchito 316 zosapanga dzimbiri kapena duplex?" Yankho lagona mu khalidwe la electrochemical-osati timabuku ta malonda. Aloyi 400 (Ni-Cu, ~ 67% Ni / 30% Cu) imakana kuchepetsa zidulo monga hydrofluoric ndi sulfuric komwe kulephera kumalephera. Tawona mavavu a 316 akuwononga m'miyezi ya 9 mkati mwa mzere wotengera phosphoric acid; m'malo Aloyi 400 pisitoni ndodo inatenga zaka 4.7. Kusatetezedwa kwake pakubowola kwamadzi am'nyanja komanso kuwonongeka kwa dzimbiri sikungoyerekeza - kumatsimikiziridwa mu labu yathu yovomerezeka ya ISO 17025 pogwiritsa ntchito mayeso a kumiza a ASTM G36 ndi kuyesa kwapang'onopang'ono kwa ASTM F1113.
Koma Alloy 400 si pulagi-ndi-sewero. Kutsika kwake kowumitsa ntchito kumafuna zida zapadera: zoyikapo za carbide zokhala ndi nkhope zopukutidwa, zodulidwa mozama (≤0.3 mm), ndi zoziziritsa kumadzi za kusefukira kwamphamvu kwa bar 65. Wokasitomala m'modzi anayesa kuyipanga pa lathe ya cholowa yokhala ndi zida za HSS-zidabweretsa 42% kuchulukirachulukira ndi macheza opitilira GD&T kulolerana kwa ± 0.025 mm. Tsopano tikuphatikizanso kuwunika kwaulere kwa RFQ iliyonse, kuyika zovuta zomwe zingachitike ngati kupotoza kwakhoma kocheperako kapena kusagwirizana kwakukula kwamafuta panthawi ya chithandizo cha kutentha.
Kumene Precision Machining Amakumana ndi Corrosion-Critical Geometry
Zolephera zambiri sizimachitika chifukwa cha kusankha kwazinthu-koma kuphatikizika kwa geometry. Malo osindikizira olakwika pa Alloy 400 pressure valve body amatha kuthamangitsa dzimbiri ndi 300%. Ichi ndichifukwa chake ndondomeko yathu imayika ma metrology pazigawo zitatu: kutsimikizira koyambirira kwa CMM kwa kutsika kwamitengo yaiwisi, kuyeza kolondola kwa ulusi wotsogola (kofunikira pa API 6A tsinde la valve pachipata), ndi kutsimikizira komaliza kwa pamwamba kudzera pa interferometry yoyera.
Nthawi zonse timatulutsa magawo omwe ogulitsa wamba amatsika: 120-mm-diameter Alloy 400 cylinder liners ndi 0.01 mm makulidwe a khoma kutalika kwa 450 mm; mapampu nyumba zobowola zosazungulira zimafuna ± 0.008 mm cylindricity; ndi ma nozzles opindika okhala ndi mainchesi 0.005 mm pakati pa malo olowera ndi otuluka. Izi si kulolerana - timawatsimikizira. Chilichonse chomwe chatumizidwa chimaphatikizanso malipoti athunthu otsatiridwa ndi miyezo ya NIST, kuphatikiza malipoti oyesa mphero omwe akuwonetsa zenizeni za Cu/Ni/Fe/C—osati “zogwirizana ndi zomwe zanenedwazo.”
Kuchokera Kuyimba Mpaka Kumaliza: Chifukwa Chake Kuphatikizika Kwamagawo Kuli Kofunikira
Ogulitsa ena amatulutsa Alloy 400 kuponyera ndiye makina. Sititero. Chifukwa chiyani? Chifukwa kusankhana kwa dendritic mu as-cast Alloy 400 kumapangitsa madera olemera a Cu-odziwika kuti aziwukira mwamakonda. Njira yathu yopangira mchenga imagwiritsa ntchito mitengo yokhazikika yokhazikika komanso kukhazikika kwapambuyo pa 1150 ° C kwa maola 4 - kutsimikiziridwa ndi kusanthula kwa microprobe. Izi zimathetsa banding, zimatsimikizira kugawa kwa 67.2 ± 0.3% Ni, ndikupereka kuuma kosasinthasintha (130-160 HBW) kudutsa gawo lonse.
Kuwongolera uku kumafikira pakumaliza. Electropolishing imagwira ntchito bwino pa Alloy 400 chifukwa cha mawonekedwe ake amitundu iwiri. M'malo mwake, timagwiritsa ntchito eni eni a citric-nitric passivation blend akutsatiridwa ndi akupanga kuyeretsa m'madzi a deionized-ovomerezeka pa ASTM A967 Njira D. Makasitomala amafotokoza 2.3 × moyo wautali wautumiki mu malupu ozizirira odzaza ndi chloride poyerekeza ndi njira zina zopukutidwa ndi makina.
Kusankha Aloyi Yabwino 400 Part Partner-Beyond the Data Sheet
Yang'anani zizindikiro zitatu: Choyamba, umboni wa kusanthula kwenikweni kwa dziko - osati mawu omvera. Timasunga zolemba za anthu zofufuza zomwe zimayambitsa (zosadziwika) zomwe zimaphimba hydrogen embrittlement mu ntchito ya H₂S ndi kulumikiza galvanic ndi ma flanges a carbon steel. Chachiwiri, zowongolera zolembedwa: Kodi zimatchula nthawi yonyowa? Mtengo wotsitsa? Kutsimikizika kwa kukula kwambewu pa ASTM E112? Chachitatu, kulabadira ma callouts a GD&T —makamaka mbiri, kutha, komanso kuphatikiza. Ngati chojambula chanu chikuwonetsa zosintha za MMC kapena zoyeserera za datum, gulu lawo logwira mawu liyenera kulankhula chilankhulocho bwino.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito motere chifukwa mbali zolimbana ndi dzimbiri sizinthu. Ndiwothandizira dongosolo. Kulephera kwa gawo limodzi la Alloy 400 mu gawo lowongolera la subsea kumatha kuyambitsa $ 2.4M pamitengo yotsika. Ichi ndichifukwa chake timawona dongosolo lililonse-kuyambira pa prototype mpaka kupanga-monga ntchito yofunika kwambiri. Timatumiza magawo a Alloy 400 ku North America, Europe, ndi Southeast Asia ndi zinthu zonse zowoneka bwino, certification ya dimensional, ndi chithandizo chaumisiri chomwe chimapangidwa mu mawuwo - osawonjezedwa ngati chiwongola dzanja.
Pazofunsira zomwe zimafuna kuti ziro zisinthidwe pakukana dzimbiri, kukhulupirika kwa mawonekedwe, komanso kusasinthika kwazitsulo - Aloyi 400 mbali zochokera ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amapangidwa kuti azichita, amatsimikiziridwa kuti atsimikizire, ndikuperekedwa kuti machitidwe aziyenda.
