Zipangizo zolimbitsa thupi kwambiri za 0Cr13Ni8Mo2Al (13-8Mo) mvula ya chitsulo chosapanga dzimbiri cholimba
Ubwino wa magwiridwe antchito azinthu
1. Kuphatikiza kwangwiro kwa mphamvu yayikulu ndi kulimba kwakukulu
Kapangidwe kapadera ka kapangidwe:
Cr | Mu | Kwa | Al |
12.25% -13.25% | 7.5% - 8.5% | 2.00% -2.50% | 0.90%-1.35% |
Kudzera mu kutentha (H950 ndi zina), mphamvu yokoka imatha kufika pamwamba pa 1515 MPa ndipo mphamvu yotulutsa imatha kufika pamwamba pa 1415 MPa, pomwe ikusunga kutalika kwa 10% ndi mphamvu yokoka ya 39 J, yomwe ndi yapamwamba kwambiri kuposa chitsulo chosapanga dzimbiri cha martensitic.
Chomera cha aluminiyamu (Al) chimapanga gawo la NiAl intermetallic compound, lomwe limagwa panthawi yokalamba kuti liwonjezere mphamvu ya mvula, pomwe kuwonjezera kwa molybdenum (Mo) kumawonjezera mphamvu, kulimba komanso kukana kutentha kwa zinthuzo.
2. Kukana dzimbiri kwabwino kwambiri
Kuchuluka kwa chromium kumapereka kukana kwa dzimbiri kwa matrix, makamaka akale, kukana kwake ku stress corrosion cracking (SCC) kuli bwino kwambiri kuposa kwa zitsulo zosapanga dzimbiri zokhazikika monga 17-4PH.
Imagwira ntchito bwino kwambiri m'madzi a m'nyanja, m'mlengalenga wonyowa komanso m'malo opopera mchere, ndipo ndi yoyenera kugwiritsidwa ntchito kwa nthawi yayitali m'malo ovuta.
3. Kugwira ntchito bwino kwambiri pakutopa komanso kulimba kwa kusweka
Kusungunula vacuum kawiri kumachepetsa kwambiri kuchuluka kwa okosijeni ndi mpweya woipa ([O]≤20ppm, [N]≤60ppm), zomwe zimapangitsa kuti pakhale mphamvu yotopa kwambiri komanso kuti pakhale ming'alu yochepa.
Imathabe kukhalabe ndi mphamvu zambiri komanso kukhazikika pamalo otentha kwambiri (≤430℃) ndipo imakhala ndi kukana kwabwino kwa kukwawa.
4. Kugwira ntchito bwino kwa njira
Mkhalidwe wa yankho lolimba (Mkhalidwe A) uli ndi kuuma kochepa (HRC≈32), zomwe zimapangitsa kuti zikhale zosavuta kupanga makina, kupanga kozizira ndi kusungunula (TIG/MIG).
Kupyolera mu kukalamba kochepa kocheperako (510 ℃ -595 ℃), ndi kusintha pang'ono kwa kutentha, zomwe zimapangitsa kuti ikhale yoyenera kupanga zigawo zolondola.
Madera ogwiritsira ntchito wamba
Zamlengalenga: Masamba a compressor a injini, ma turbine shafts, magiya, zomangira ndi zida zomangira zomwe zimakwaniritsa zofunikira za FAA, NASA, ndi zina zotero.
Makampani a Nyukiliya ndi Mphamvu: Zigawo za reactor ya nyukiliya, masamba a turbine ya nthunzi, mipata ya pampu yamphamvu kwambiri, yolimba pa kutentha kwambiri komanso yokhazikika pa kutentha kwambiri.
Zida zankhondo: zida zomangira zida zankhondo, zida zankhondo zam'madzi, ndi zida zonyamula katundu zamagalimoto otetezedwa, poganizira zosowa zopepuka komanso zoteteza.
Kupanga kwapamwamba kwambiri: Zipangizo zobowolera mafuta, zipangizo zachipatala (zogwirira mpeni zochitira opaleshoni, zinthu zoyikamo), kugwirizana bwino kwa zinthu zina.
Chidule
0Cr13Ni8Mo2Al (13-8Mo), chifukwa cha kuyera kwake kwakukulu komwe kumachitika chifukwa cha kusungunula vacuum kawiri, kulimba kwapadera, kulimba, komanso kukana dzimbiri, komanso kupirira kutentha kokhazikika, kwakhala chinthu chofunikira kwambiri m'makampani opanga ndege, nyukiliya, ndi ankhondo. Kupanga kwake kumaphatikizapo kufunafuna magwiridwe antchito apamwamba kwambiri pazida zapamwamba ndipo kumakhalabe chizindikiro cha magwiridwe antchito pakati pa zitsulo zosapanga dzimbiri zomwe zimalimbitsa mvula. Kusankha 13-8Mo kumatanthauza kusankha kudalirika koyenera komanso magwiridwe antchito apamwamba!
