Magawo a Monel 400 amapereka kukana kosagwirizana ndi madzi a m'nyanja, ma acid, ndi alkalis - kuwapangitsa kukhala ofunikira pomwe kulephera sikungachitike. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., tapanga makina opitilira 12,000 a Monel 400 a mavavu opangira ma hydraulic, nyumba zapampopi zam'madzi, ndi mazenera akunyanja kuyambira 2018. Akatswiri ambiri samazindikira: kusankha moyenerera Monel 400 pamlingo wocheperako, kutulutsa ukadaulo wocheperako komanso kutsika kwa chemistry. kupsinjika kopangidwa ndi makina, ndi kumaliza kwapamwamba kumalumikizana ndi malo anu ogwirira ntchito.
Chifukwa chiyani Monel 400 Imalephera—Ngakhale “Itafotokozedwa Molondola”
Tawona zifukwa zitatu zomwe zimachitika mobwerezabwereza pazovuta za 47 zomwe zimakhudza magawo a Monel 400. Choyamba: kugwiritsa ntchito ASTM B164 bar stock pomanga ma silinda othamanga kwambiri popanda kutsimikizira momwe mbewu zimayendera, zomwe zimapangitsa kuti kutopa msanga kumang'ambika m'malo okhotakhota. Chachiwiri: kugwiritsa ntchito magawo odulira zitsulo zosapanga dzimbiri pakutembenuka kwa CNC, zomwe zimapangitsa kuti ntchito ikhale yolimba yomwe imatsekereza kupsinjika kotsalira ndikuyambitsa kupsinjika kwa dzimbiri mu condensate wolemera wa chloride. Chachitatu: kudumpha pambuyo Machining asidi pickling pamaso passivation, kusiya ophatikizidwa chitsulo particles kuti kuyambitsa galvanic pitting.
Monel 400's 67% nickel-30% copper base imapatsa chitetezo chochepetsera zidulo ngati hydrofluoric-koma sichimapereka chitetezo kuzinthu zotulutsa okosijeni monga ferric chloride kapena gasi wonyowa wa chlorine. Ngati ntchito yanu ikukhudza kuyanika kwapang'onopang'ono kapena kuyendetsa njinga yamoto yopitilira 400 ° C, lingalirani za Monel K-500 m'malo mwake. Timayesa billet iliyonse ya Monel 400 yokhala ndi spark emission spectroscopy-osati kokha pa chiŵerengero cha Ni/Cu, koma za sulfure zomwe zili pansi pa 0.002%, zomwe zimakhudza mwachindunji kung'ambika kotentha panthawi yopangira ndalama.
Momwe Mungagwirizanitsire Gawo la Monel 400 ndi Katundu Wanu Weniweni Wapadziko Lonse
Yambani ndi kupanga mapu a envulopu yanu yogwirira ntchito - osati kuthamanga ndi kutentha kokha, koma kuthamanga kwamadzimadzi, kutsitsa kwa tinthu, ndi kutseka pafupipafupi. Mwachitsanzo:
- Pampu ya silinda nyumba: Amafuna centrifugally cast Monel 400 yokhala ndi ma radial njere-yopangidwa pogwiritsa ntchito otsika-RPM, amapita apamwamba kuti asunge kupsinjika kotsalira pamwamba.
- Mipando ya valve ya m'nyanja: Kufuna kupangira Monel 400 (ASTM B564) ndi kuuma pakati pa 130-160 HB; annealed akupera komaliza kuchotsa microcracks kuchokera EDM recast zigawo.
- Offshore winch center shaft rollers: Ayenera kutsekedwa ndi yankho pa 1177 ° C ± 14 ° C, ndiyeno madzi-osatsekedwa ndi mpweya - kuti ateteze sigma gawo la embrittlement m'madera okhudzidwa ndi kutentha.
Timakana 8.3% yamagulu a Monel 400 omwe akubwera chifukwa cha kusagwirizana kwa dzimbiri kwa intergranular-kutsimikiziridwa ndi kuyesa kwa ASTM G28 Njira A. Chilango chimenecho chimalekanitsa zigawo zofunika kwambiri zautumwi ndi zolemera zamapepala zodula.
Mtengo Wobisika wa "Standard" Monel 400 Fabrication
Ogula ambiri amaganiza kuti magawo a Monel 400 amawononga 3 × chitsulo chosapanga dzimbiri-ndikuyimira pamenepo. Koma mtengo wokwanira wa umwini umadalira mitundu isanu yomwe mumawongolera: kulolerana kwapang'onopang'ono, kuuma kwapamwamba, njira yotsimikizira kutentha, kuya kwa protocol yoyendera, ndi kuchuluka kwa momwe mungawonere. Ndodo ya pisitoni ya Monel 400 yokhala ndi ± 0.01 mm kulolerana ndi Ra 0.4 μm yomaliza imawononga 22% kuposa imodzi yokhala ndi ± 0.05 mm ndi Ra 1.6 μm-koma imachotsa 94% ya madandaulo a kutayikira kwa chisindikizo pamakina apamwamba kwambiri a hydraulic.
Timagwiritsa ntchito ma Zeiss CONTURA G2 CMM okhala ndi ma probes oyeserera kuti atsimikizire ma diameter ovuta pansi pa 20 ° C olamulidwa ndi mikhalidwe yozungulira - osati kutentha. Chifukwa chiyani? Chigawo cha Monel 400 cha kukula kwa kutentha ndi 13.7 μm/m·°C. Kusintha kwa 10 ° C kumabweretsa cholakwika cha 0.137 mm pa shaft ya 1,000 mm. Ichi ndichifukwa chake ziphaso zathu za gawo la Monel 400 zimaphatikizanso zolemba zachilengedwe pamodzi ndi malipoti owoneka bwino.
Zomwe Zimabwera Pambuyo Posankhidwa-Ndipo Chifukwa Chake Zimafunika Kuposa Mukuganiza
Kusankha gawo loyenera la Monel 400 kumatha pomwe mtundu wanu woyamba ufika. Zomwe zimatsatira zimatsimikizira ngati ikuchita - kapena kulephera mwakachetechete. Timachita masitepe atatu osayanjanitsika pa dongosolo lililonse: (1) kuyezetsa kwa ultrasonic pa ASTM E114 kwa porosity yamkati m'nyumba zoponyedwa, (2) kuyesa kwa ferroxyl pa ASTM A380 kutsimikizira kusapezeka kwa kuipitsidwa kwachitsulo kwaulere, ndi (3) kutsimikizika kwa utsi wa mchere pa ISO 9227 kwa maola 1,000-popanda kukhudza kapena kugwiranso ntchito.
Makasitomala athu mumapulojekiti amafuta ndi gasi aku North Sea amafunikira kutsatiridwa kwathunthu mpaka ku Inconel 600 master alloy lot yomwe imagwiritsidwa ntchito pokonzanso. Timasunga zolemba za digito zomwe zimalumikiza gawo lililonse la Monel 400 ndi nambala yake ya kutentha, kupanga ID ya kufa, chipika cha njira ya CNC, ndi sitampu yomaliza yoyendera. Palibe kuchotserapo.
Kuchita kwa gawo la Monel 400 sikutsimikiziridwa ndi kutsimikizika - kumapezedwa kudzera muukadaulo wazitsulo, kuwongolera njira, ndi kutsimikizika kwapadziko lonse lapansi. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., timachitira gawo lililonse la Monel 400 ngati lidzagwira ntchito mosayang'aniridwa ndi kuya kwa 3,000 metres. Chifukwa nthawi zambiri zimatero.
