Mokhoa oa ho Bapisa Karolo ea Monel 400 le Mojaro oa Hao oa 'Nete oa Lefatše
Qala ka ho etsa 'mapa oa enfelopo ea hau ea ts'ebetso-eseng khatello le mocheso feela, empa lebelo la mokelikeli, phallo ea likaroloana le maqhubu a ho koala. Ka mohlala:
- Mehaho ea li-cylinder tsa pompo: Hloka centrifugally cast Monel 400 e nang le sebopeho sa lijo-thollo tsa radial-e entsoeng ka ho sebelisa li-RPM tse tlaase, li-feed-feed passes ho boloka khatello ea kelello ea masala a holim'a metsi.
- Litulo tsa valve ea metsi a leoatle: Tlhokahalo e entsoeng ka Monel 400 (ASTM B564) e thata pakeng tsa 130-160 HB; annealed ka mor'a ho sila ho qetela ho felisa li-microcracks ho tloha ho EDM recast layers.
- Offshore winch center shaft rollers: E tlameha ho ba le tharollo-annealed ho 1177 ° C ± 14 ° C, ebe e tima metsi-ho se mohla e pholileng moeeng - ho thibela ho phunyeha ha sigma phase sebakeng se amehileng ke mocheso.
Re hana 8.3% ea li-batch tsa thepa e tala ea Monel 400 e kenang ka lebaka la ho hanyetsa ha kutu ea intergranular-e netefalitsoeng ke tlhahlobo ea ASTM G28 Method A. Taeo eo e arola likarolo tsa bohlokoa tsa boromuoa ho li-paperweight tse turang.
Theko e patiloeng ea "Standard" Monel 400 Fabrication
Bareki ba bangata ba nahana hore likarolo tsa Monel 400 li bitsa 3 × tšepe e sa hloekang-'me ba emise moo. Empa litšenyehelo tsohle tsa ho ba beng li ipapisitse le mefuta e mehlano eo u e laolang: stack-up ea ho mamellana ka mahlakoreng a mabeli, sebopeho sa bokaholimo ba mafika, mokhoa oa netefatso ea kalafo ea mocheso, botebo ba protocol ea tlhahlobo, le boholo ba ts'ebetso. A Monel 400 piston rod e nang le ± 0.01 mm tolerance le Ra 0.4 μm qetellong e bitsa 22% ho feta e le 'ngoe e nang le ± 0.05 mm le Ra 1.6 μm-empa e felisa 94% ea litletlebo tsa ho lutla ha tiiso tsamaisong e phahameng ea li-hydraulic system.

Ke ka lebaka leo litifikeiti tsa rona tsa Monel 400 li kenyelletsang lintlha tsa tikoloho hammoho le litlaleho tsa maemo.
Se Tlang Ka mor'a Khetho-Le Hobaneng ho le Bohlokoa ho Feta Hore U Nahana
Ho khetha karolo e nepahetseng ea Monel 400 ho fela ha prototype ea hau ea pele e fihla. Se latelang ke sona se bontšang hore na sea sebetsa—kapa se hlōlehile ka khutso. Re etsa mehato e meraro e ke keng ea buisanoa ka tatellano e 'ngoe le e' ngoe: (1) tlhahlobo ea ultrasonic ka ASTM E114 bakeng sa porosity ea ka hare ho li-cast housings, (2) tlhahlobo ea ferroxyl ka ASTM A380 ho netefatsa ho ba sieo ha tšilafalo ea tšepe e sa lefelloeng, le (3) tiiso ea ho fafatsa letsoai ka ISO 9227 bakeng sa lihora tse 1,000-ntle le ho ama kapa ho tsosolosa.
Bareki ba rona mererong ea oli le khase ea Leoatle la Leboea ba hloka ho ts'oaroa ka botlalo ho fihlela ho "Inconel 600 master alloy lot" e sebelisitsoeng ho lokisa. Re boloka lirekoto tsa dijithale tse hokahanyang karolo e 'ngoe le e' ngoe ea Monel 400 le nomoro ea eona ea mocheso, ho etsa ID ea ID, lethathamo la lisebelisoa tsa CNC, le setempe sa ho qetela sa tlhahlobo. Ha ho mekhelo.
Ts'ebetso ea karolo ea Monel 400 ha e tiisetsoe ka litlhaloso-e fumanoa ka taeo ea tšepe, taolo ea ts'ebetso, le netefatso ea lefats'e la nnete. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., re tšoara karolo e 'ngoe le e 'ngoe ea Monel 400 joalokaha eka e tla sebetsa e sa hlokomeloe ka botebo ba limithara tse 3,000. Hobane hangata ho joalo.
