Zomwe Muyenera Kutsimikizira Mukapeza Magawo a Monel Alloy

Kugula kwa gawo la Monel alloy kumalephera m'njira zodziwikiratu: kalasiyo ndi yosamvetsetseka, muyezo ulibe, njira yosinthira imasiyidwa kwa wogulitsa popanda ziyeneretso, kapena zofunikira zowunikira sizinafotokozedwe. Mndandanda wotsimikizira pansipa wakonzedwa motsatira zisankho zomwe zimakhudza ngati gawo loperekedwa likuchita.

Zofunika kalasi ndi muyezo. Lamulo logulira liyenera kunena nambala ya UNS, osati dzina lamalonda lokha. Kwa Monel 400, ndiye UNS N04400; kwa Monel K-500, UNS N05500. Mulingo woyenera wazinthu uyeneranso kutchulidwa: mwachitsanzo, ASTM B127 ya mbale, B164 ya bala, B165 ya chubu, B564 ya forgings, kapena B865 ya K-500 bar, ndodo, ndi forgings, kutengera mtundu wa malonda ndi kalasi. Kwa ma castings, zomwe zikuyenera kuchitika za ASTM ziyenera kutsimikiziridwa padera lamulo logulira lisanaperekedwe; Miyezo yomwe yatchulidwa pamwambapa mafomu opangidwa ndi chivundikiro ndi K-500 bar/forgings, osati zogula za Monel casting. Chojambula chomwe chimati "Monel" chopanda nambala ya UNS ndi mawonekedwe amtundu wazinthu zimasiya wogulitsa kuti azitha kutanthauzira zofunikira.

Zojambula, miyeso, ndi kulolerana. Pazigawo za Monel zachizolowezi, zojambulazo ziyenera kukhala zamakono, ndipo miyeso yovuta, kulolerana, mapeto a pamwamba, ndi maulusi a ulusi ayenera kukhala omveka. Pazojambula, chojambulacho chiyenera kusiyanitsa malo oponyedwa ndi makina opangidwa ndi makina ndipo chiyenera kutchula malipiro a makina ndi zofunikira zolembera. Pazigawo zamakina, dongosolo la datum ndi njira yowunikira ziyenera kukhala zosamveka.

Kutsimikizira ndondomeko yopanga. Wogula ayenera kudziwa ngati wogulitsa akufuna kuponya, makina kuchokera ku bar kapena forging, kapena kuphatikiza zonse ziwiri. Ngati kuponyedwa kwapangidwa, chidziwitso cha nickel-copper cha foundry ndi njira yowunikira bwino ziyenera kutsimikiziridwa. Ngati makinawa akufunidwa, njira ya woperekera katunduyo yowongolera ntchito ndi zida ziyenera kukhala gawo la zokambirana zaukadaulo. Kuponyera aloyi ya Monel ndi makina a Monel alloy sizosintha zosinthika; ali ndi ma profailo osiyanasiyana.

Kutentha mankhwala ndi chikhalidwe. Kwa Monel K-500, chithandizo cha ukalamba ndi njira yodziwika bwino ndipo iyenera kutsimikiziridwa molingana ndi zomwe zikugwiritsidwa ntchito komanso mawonekedwe azinthu. Kwa Monel 400, vutoli - losasunthika, lochepetsera nkhawa, kapena lozizira - liyenera kunenedwa chifukwa limakhudza mphamvu, miyeso, ndi machitidwe a makina. Satifiketi yomwe imanena za "Monel K-500" popanda ukalamba ndi yosakwanira.

Kuyendera ndi zolemba. Satifiketi yoyesera zinthu yokhala ndi mankhwala komanso makina amakina ndiye maziko. Pakupanga, wogula atha kufotokozera ma radiographic, olowera, kapena kuyang'ana akupanga kutengera kukakamizidwa kwa gawo kapena ntchito yake. Kwa magawo opangidwa ndi makina, malipoti oyendera mawonekedwe ndi zolemba zomaliza ndi umboni wofanana. Kuwona kwa kutentha kuyenera kusungidwa kuyambira pa satifiketi ya mphero mpaka kumapeto.

Mndandanda wamafunso ophatikizika ndiwothandiza: kalasi yazinthu ndi nambala ya UNS; muyeso wa ASTM kapena AMS wamtundu wazogulitsa; kujambula kukonzanso ndi miyeso yovuta; njira yopangira (kuponyedwa, makina, kapena zonse ziwiri); kutentha mankhwala chikhalidwe; kuyendera zofunikira ndi zolemba; ndi kutentha kwambiri traceability. Pazotengera zokhazikika za Monel kapena ma bawuti a monelo, nambala yokhazikika ndi giredi zimalowa m'malo mwa chojambulacho, koma satifiketi yazinthu ndi zowunikira zimakhalabe.
