Dachang zenizeni 304L zogulitsa zitsulo zosapanga dzimbiri
American Iron and Steel Institute imagwiritsa ntchito manambala atatu kuyika milingo yosiyanasiyana
Zosasinthika. Za zomwe:
① Chitsulo chosapanga dzimbiri cha Austenitic chikuwonetsedwa ndi manambala a 200 ndi 300 mndandanda,
②Zitsulo zosapanga dzimbiri za ferritic ndi martensitic zimayimiriridwa ndi manambala 400. Mwachitsanzo, zina mwazitsulo zosapanga dzimbiri za austenitic
Zizindikiro 201, 304L, 316 ndi 310,
③ Chitsulo chosapanga dzimbiri cha Ferritic chili ndi 430 ndi 446, ndipo chitsulo chosapanga dzimbiri cha martensitic chili ndi 410, 420 ndi 440C.
Zindikirani, duplex (austenite ferrite),
④ Chitsulo chosapanga dzimbiri, mvula yowumitsa chitsulo chosapanga dzimbiri ndi aloyi wapamwamba wokhala ndi chitsulo chosakwana 50% nthawi zambiri amatenga dzina lachidziwitso kapena dzina lamalonda.
① Zizindikiro zapadziko lonse lapansi za mankhwala ndi zizindikilo za dziko zimagwiritsidwa ntchito kuyimira mankhwala, ndipo zilembo za Chiarabu zimagwiritsidwa ntchito kuyimira zomwe zili mugawo lake:
Mwachitsanzo: China, Russia 12CrNi3A
②Gwiritsani ntchito manambala okhazikika kuti muyimire mndandanda wazitsulo kapena manambala; Mwachitsanzo, United States, Japan, 300 mndandanda, 400 mndandanda ndi 200 mndandanda.
③ Nambala ya siriyo imapangidwa ndi zilembo za Chilatini ndi dongosolo, zomwe zimangosonyeza cholinga.
Kugwiritsa ntchito, Pinyin yaku China, chitsulo chotseguka: P, chitsulo chowira: F, chitsulo chopha: B, kalasi yachitsulo: A, T8: te8
GCr15: Mpira
◆ zomangira zitsulo ndi zitsulo masika, monga 20CrMnTi 60simn, (C zili zikufotokozedwa mu zikwi khumi)
◆ zitsulo zosapanga dzimbiri ndi aloyi chida zitsulo (C zili zikufotokozedwa mu thousandths), monga 1 zikwi za 1Cr18Ni9 (ie
0.1% C), zosapanga dzimbiri C ≤ 0.08%, monga 0Cr18Ni9, ultra-low carbon C ≤ 0.03%, monga 0cr17ni13mo
Kulemera pa mita imodzi ya 304L chitoliro chosapanga dzimbiri = m'mimba mwake - makulidwe a khoma x makulidwe a khoma x0.02491
Element zili 304L zosapanga dzimbiri chitoliro c ≤ 0.03, ni8.00 ~ 12.00, cr18.00 ~ 20.00, Mn <= 2.0, Si <= 1.0, s <= 0.030, P <= 0.035.
304L zosapanga dzimbiri chitoliro 18cr-8ni-otsika mpweya monga Low-C 304 zitsulo, kukana dzimbiri ndi ofanana ndi zitsulo 304 ambiri, koma malire ake dzimbiri kukana dzimbiri ndi zabwino pambuyo kuwotcherera kapena mpumulo kupsinjika; Itha kukhalabe kukana bwino kwa dzimbiri popanda chithandizo cha kutentha, komanso kutentha kwautumiki ndi -196 ℃ ~ 800 ℃. Amagwiritsidwa ntchito pamakina akunja m'mafakitale amafuta, malasha ndi mafuta omwe ali ndi zofunika kwambiri pakukana kuwononga malire a tirigu, mbali zosagwira kutentha kwa zida zomangira ndi magawo omwe amavutikira kutentha kutentha.
Cholinga: Amagwiritsidwa ntchito makamaka paukadaulo wamadzi akumwa komanso zoyendera zina zamadzimadzi zomwe zimakhala ndi zofunika kwambiri
Zinthu zazikulu: moyo wautali wautumiki; Mlingo wochepa wolephera komanso kutsika kwamadzi; Mkhalidwe wamadzi wotumizira ndi wabwino, ndipo palibe zinthu zovulaza zomwe zidzalowe m'madzi; Khoma lamkati la chitoliro ndi losalala ndipo lili ndi kukana kwamadzi otsika; Kuchita kwamtengo wapamwamba, moyo wautumiki mpaka zaka 100, palibe kukonza ndi kutsika mtengo; Ikhoza kupirira kukokoloka kwa madzi othamanga kwambiri kuposa 30m / S; Kuyika chitoliro chowonekera ndi mawonekedwe okongola.
Ntchito: mkaka ndi chakudya makampani, makampani mankhwala, mafakitale ndi zofunika zapadera pamwamba pamwamba.
ndondomeko mbali: mkati weld mikanda kusalaza mankhwala, olimba njira mankhwala, mkati padziko electrolytic kupukuta.
Magwiridwe ake: mkati pamwamba roughness Ra ndi oposa 0,2, khoma zotsalira atapachikidwa ndi yaing'ono, zosavuta kuyeretsa, kuteteza bakiteriya kukula, electrolytic kupukuta ali passivation tingati, ndipo khoma lamkati ali ndi ntchito yabwino chitetezo.
Njira zoyesera: chopingasa, kupendekeka kwautali, kubwezeredwa mmbuyo, kuyesa kwa hydrostatic kapena kuzindikira zolakwika za eddy, kuyesa katundu wamakina, kuyesa kwamkati kwamkati.
