Maboti a Monel amapereka mphamvu zosayerekezeka ndi dzimbiri pomwe zomangira wamba zimalephera—mapampu amadzi a m’nyanja, mavavu a gasi wowawasa, ma hydraulic manifolds a m’mphepete mwa nyanja. Tapanga ma bolts opitilira 12,000 a Monel K-500 ndi Monel 400 opangira nyumba zopopera zothamanga kwambiri kuyambira 2019. Iliyonse idapulumuka kuyezetsa kopopera mchere kupitilira maola 3,000 popanda kubowola. Kumeneko sikuli kachitidwe kongoyerekeza. Ndiko kudalirika kotsimikizika pamunda pansi pa katundu weniweni wa cyclic, kugwedezeka kwamafuta, komanso mlengalenga wodzaza ndi chloride.
Maboti a Monel sikuti ndi "chitsulo chosapanga dzimbiri-kuphatikiza." Ndi ma aloyi a nickel-copper—nthawi zambiri 67% faifi tambala, 23% yamkuwa, kuphatikiza zing’onozing’ono koma zofunikira kwambiri za aluminiyamu ndi titaniyamu mu K-500. Kapangidwe kameneka kamapanga ma microstructures olimba kwambiri omwe amakana kusweka kwa dzimbiri kuposa zitsulo zosapanga dzimbiri 316 kapenanso ziwiri. Pamsonkhano wina wamakasitomala wakunyanja, kusintha kuchokera ku Inconel 625 bolt kupita ku Monel K-500 kunachepetsa ma frequency a bolt ndi 70% pa miyezi 18. Chifukwa chiyani? Chifukwa Monel imasunga mphamvu zokolola kuposa 1,000 MPa pomwe imalimbana ndi dzimbiri pa pH 2-12 ndi kutentha mpaka 480 ° C.
Koma mabawuti a Monel amafuna ulemu—osati kusimikiridwa kokha. Chiwopsezo chawo chogwira ntchito ndizovuta kwambiri. Kupopera kamodzi kolakwika panthawi yodula ulusi kumatha kuthyola chopanda kanthu. Tawona makasitomala akutaya magulu onse chifukwa adagwiritsa ntchito matepi wamba a HSS m'malo mwa zida za carbide zotumiza zoziziritsa kukhosi. Monel imayendetsanso kutentha bwino. Popanda kuwongolera bwino kwa kutentha panthawi ya makina, kuyatsa kwapadera kumafewetsa muzu wa ulusi—kuchepetsa moyo wa kutopa pakati. Ichi ndichifukwa chake timatenthetsa malo opanda kanthu mpaka 120 ° C tisanalowe ulusi, gwiritsani ntchito mphero zoziziritsidwa ndi cryogenic, ndikutsimikizira kuuma kwa magawo atatu a radial pagawo lililonse. Palibe njira yachidule yomwe ingakhalepo ndi aloyiyi.
- Kusankha zinthu ndizofunikira kwambiri kuposa nambala ya giredi. Monel 400 imagwirizana ndi madzi a m'nyanja osasunthika; Monel K-500 imawonjezera kulimbitsa ukalamba pakusunga ma torque amphamvu pamapampu ozungulira.
- Ulusi wa geometry siwosankha - umagwira ntchito. Ulusi wa Unified National Fine (UNF) umachita bwino kwambiri kuposa mazenera owoneka bwino m'malo ogwedezeka kwambiri pogawa katundu wa clamp molingana.
- Kumaliza kwapamwamba kumakhudza kuyambika kwa dzimbiri. Ra ≤ 0.4 μm imalepheretsa ting'onoting'ono tating'ono pomwe ma chloride amakhazikika; electropolishing amachepetsa kungokhala wosanjikiza zolakwika ndi 92% motsutsana ndi makina opukuta okha.
Ena angatsutse ma bolts a Monel amawononga ndalama zambiri-mpaka 4 × kuposa A2-70 zosapanga dzimbiri. Komabe, mtengo wonse wa umwini umafotokoza nkhani yosiyana. Wogwiritsa ntchito wina waku North Sea adatsata ma hydraulic manifold 14 m'miyezi 24. Ndi ma bolts osapanga dzimbiri, adayimitsa 19 mosakonzekera kuti alowe m'malo mwa bawuti ndikuyikanso gasket. Ndi ma bawuti a Monel K-500, adathamanga miyezi 22 popanda kutayikira kumodzi. Ndalama zogwirira ntchito, nthawi yocheperako, komanso zotsimikizira chitetezo zimatsika ndi $217,000 pachaka. Kulimbana ndi kutu si chinthu. Kukonzekera kochedwetsedwa-ndi chiopsezo chochedwetsedwa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. makina mabawuti a Monel pogwiritsa ntchito malo ovomerezeka a CNC a ISO 9001 okhala ndi chipukuta misozi nthawi yeniyeni. Timatulutsa ma billets ovomerezeka a AMS 4675, kutsimikizira momwe mbewu zimayendera musanapange, ndikuwunikanso akupanga pa batch iliyonse kuti tidziwe zophatikizika. Njira yathu imaphatikizapo njira yothetsera annealing pa 980 ° C ± 5 ° C, kuzimitsa madzi mofulumira, kenako kukalamba pa 650 ° C kwa maola 16 - makamaka pa ASTM B564. Bawuti iliyonse imakhala ndi kutsata kokwanira: nambala ya kutentha, lipoti loyeserera, kuyesa kwa dzimbiri kwapakati (ASTM G28A), ndi data ya CMM yosungidwa zaka 10. Mukafuna mabawuti a Monel omwe amakhala ndi torque pambuyo pa kukakamiza kwa 50,000 mu 95 ° C brine - sitikuganiza. Timayesa, kutsimikizira, ndi chitsimikizo.
Kuyang'ana m'tsogolo, mabawuti a Monel akusintha kupitilira kukhazikika. Tsopano tikuyika ma geji amtundu wamtundu wa Monel 400 bolt shanks kuti tiwunikiretu nthawi yeniyeni pamakina ofunikira. Mapangidwe a m'badwo wotsatira amaphatikiza tinjira tating'ono tomwe titha kuperekera mafuta ophatikizika panthawi yogwira ntchito - kukulitsa nthawi yantchito mumayendedwe akutali amafuta. Tsogolo silili la ma bolt amphamvu a Monel. Ndi za anzeru - opangidwa ndi cholinga, ovomerezeka ndi deta, komanso omangidwa pomwe kulephera sikungatheke. Ngati ntchito yanu ikufuna kusokoneza kukhulupirika, chemistry, kapena kusasinthasintha, ma bolts si chisankho chanu chabwino. Ndiwo kusankha kwanu kokha.
