MONEL Alloy K-500 (UNS N05500/ WR2.4375) ndi aloyi ya nickel-copper yomwe imaphatikiza ubwino wa kukana kwa dzimbiri ndi kuuma kwakukulu kwa MONEL alloy 400. Aluminiyamu ndi titaniyamu zinawonjezeredwa ku maziko a nickel-copper ndi kutenthedwa. pansi pamikhalidwe yoyendetsedwa kuti ipangitse tinthu tating'onoting'ono ta Ni3 (Ti, AI) m'munsi mwa nickel-copper, motero kuwongolera magwiridwe antchito.Kugwiritsa ntchito ntchito yotentha kuti mukwaniritse mvula nthawi zambiri kumatchedwa kukalamba kuuma kapena kukalamba.
Zomwe zimagwiritsidwa ntchito pazinthu za MONEL alloy K-500 ndi zomangira ndi ma chingwe ndi akasupe.
Ntchito Zam'madzi: Pampu ndi ma valve,
Mankhwala mankhwala: zamkati processing kupanga mapepala kwa masamba dokotala ndi scrapers;
Kubowola bwino kwamafuta ndi zida, shaft yapampu ndi chopondera, nyumba zopanda maginito, kukweza chitetezo ndi valavu yamafuta ndi kupanga gasi;Ndipo masensa ndi zida zina zamagetsi zamagetsi.
Chimodzi mwa zinthu za Monel K500 aloyi ndi kuti pafupifupi sanali maginito, ngakhale pa kutentha otsika.Komabe, n'zotheka kupanga maginito wosanjikiza pamwamba pa zinthu panthawi yokonza.Aluminiyamu ndi mkuwa amatha kuthiridwa okosijeni mwa kutenthedwa, ndikusiya filimu yolemera kwambiri ya nickel kunja kwa pepala.Izi zimawonekera makamaka pa waya woonda kapena mzere wokhala ndi chiŵerengero chapamwamba cha kulemera kwa thupi.Filimu ya maginito imachotsedwa ndi pickling kapena leaching yowala ya asidi kuti abwezeretse zinthu zopanda maginito za zinthuzo.Kuphatikizika kwa kutsika kochepa, mphamvu yayikulu, komanso kukana kwa dzimbiri kwagwiritsidwa ntchito pazinthu zambiri, makamaka zida zoyezera bwino ndi zida zamagetsi.
Zapezeka kuti Monel alloy K-500 ili ndi kukhazikika kwabwino kwambiri pakuyesa kwanthawi yayitali komanso mayeso ozungulira.Katunduyu wa alloy amalola kuti agwiritsidwe ntchito pazida zolondola kwambiri monga gyros.Mndandanda wazinthu zowonongeka ndi kuuma kwa kutentha kwa chipinda zikuwonetsedwa mu Table 6. Kugwirizana kwapafupi pakati pa katundu wokhazikika ndi kuuma kwa mipiringidzo ndi zopangira zikuwonekera mu Mkuyu.4 ndi 5, ndipo maubwenzi ofanana a mapepala ndi mizere amawonekera mu Chithunzi 6. Gulu 7 likufananiza machitidwe a notch a zitsanzo zosalala.Nthawi yochepa komanso kutentha kwambiri kwazitsulo za K500 aloyi pansi pazikhalidwe zosiyanasiyana zikuwonetsedwa mu chithunzi pansipa.Ndodo zotentha zotentha zinayesedwa pa liwiro la 0.016 mainchesi / min kupyolera mu mphamvu zokolola ndi 0.026 mainchesi / min kuchokera kumeneko kuti ziswe.Zitsanzo zozizira zozizira zinayesedwa pa mphamvu zokolola za 0.00075 mainchesi/mphindi, zotsatiridwa ndi 0.075 mainchesi/mphindi.
K-500 Monel alloy imakhala ndi kutentha kochepa kwambiri.Kulimba kwamphamvu ndi mphamvu zokolola zimawonjezeka ndi kutentha kochepa, pomwe pulasitiki ndi kulimba sizimakhudzidwa.Ngakhale pa kutentha kotsika ngati hydrogen yamadzimadzi, kusintha kuchokera kumphamvu kupita ku brittle sikuchitika.Choncho, alloy ndi oyenera ntchito zambiri otsika kutentha.Kuchita kwa K-500 alloy base iron and welded sheet sheet pa -423 ° F kukuwonetsedwa.Ngati chithandizo ukalamba ikuchitika pambuyo kuwotcherera annealing zakuthupi, kuwotcherera ndi mphamvu ukalamba anaumitsa m`munsi zitsulo popanda kutaya kwambiri ductility angapezeke.Kuwotcherera kwa zinthu zakale zolimba kuyenera kupewedwa chifukwa ductility yawo imachepetsedwa kwambiri.
MONEL alloy K-500 amatchulidwa kuti UNS N05500 ndi Werkstoff NR.2.4375.Zalembedwa mu NACEMR-01-75 Oil and Gas Services.Aloyi K-500 imapezeka mumitundu yosiyanasiyana ya mphero kuphatikiza chubu, chubu, mbale, mizere, mbale, mbale yozungulira, bala lathyathyathya, forgings, hexagon ndi waya.Mbale, Mapepala ndi Mzere -BS3072NA18(Plate ndi Mzere),BS3073NA18(Mzere),QQ-N-286(Plate, sheet and Strip),DIN 17750(Plate, Mapepala ndi Mzere),ISO 6208(Mapepala, Mapepala ndi Mzere) Mipiringidzo, Mipiringidzo, Mawaya ndi Zopangira -BS3075NA18(Waya), BS3076NA18(Ndodo ndi ndodo),ASTM B 865(Ndodo ndi ndodo),DIN 17752(Ndodo ndi ndodo),DIN 17753(Waya),DIN 17754(Forgings),QQ -N-286(Ndodo, Ndodo, Waya ndi Forgings), SAE AMS 4676(Ndodo ndi ndodo),ASME Code Case 1192(Ndodo ndi ndodo),ISO 9723(ndodo),ISO 9724(Waya),ISO9725(Forgings) Tubes ndi Machubu -BS3074NA18(Machubu osasunthika ndi machubu),DIN 17751(Machubu ndi machubu) Zinthu Zina -DIN 17743(Chemical Composition),SAE AMS 4676(Chemical composition),QQ-N-286(Chemical composition)
