AISI 8620 fakitale yopanga ndalama si mawu chabe - ndi chizindikiro cha magwiridwe antchito. Pamene sitima yanu yamagetsi iyenera kupulumuka maulendo a 150,000 pansi pa 350 MPa hydraulic load, kapena nyumba yanu yotumizira magalimoto imalekerera kugwedezeka mobwerezabwereza kuchokera ku -40 ° C mpaka + 180 ° C, kusankha kwakuthupi ndi kulamulira ndondomeko kumasiya kukhala zosankha. Amakhala osakambirana. Chitsulo cha AISI 8620 chimapereka chiyerekezo choyenera: kulimba kozama kuchokera ku nickel-chromium-molybdenum alloying, microstructure yabwino kwambiri pambuyo pa carburizing, komanso kulimba kwapadera kwapakati-* ngati * njira yoponyerayo isunga zitsulo zake. Ndipamene ambiri ogulitsa amalephera - osati pa chithandizo cha kutentha, koma kale: mu mapangidwe a nkhungu, kukhazikika kwa zipolopolo, ndi kulamulira kolimba.
Chifukwa chiyani AISI 8620 Imafunikira Kuyika Ndalama—Osati Mchenga Kapena Kufa
Kuponyera mchenga kumapangitsa kuti njere zikhwime pafupi ndi makoma a nkhungu; kufa kuponya sikungathe kuthana ndi malo osungunuka kwambiri a AISI 8620 (1490 ° C) kapena kukhudzidwa kwake ndi ming'alu yozizirira mwachangu. Kuponya ndalama kumathetsa zonsezi. Chigoba chake cha ceramic chimalola kukhazikika pang'onopang'ono, kolunjika-kofunikira kuti akwaniritse kuya kwamilandu yofananira panthawi yobisala carburizing. Tayezera mpaka 22% kusintha kwa kulimba kwa zone zone kulimba kofanana ndi mchenga wa mchenga pazida zomwezo. Zowonjezereka: chonyamulira mapulaneti omwe tidapereka kwa kasitomala wa Tier-1 EV drivetrain adawonetsa 0.08 mm dimensional drift pambuyo pa maola 500 akuyesa mavalidwe othamanga - motsutsana ndi 0.21 mm mumchenga wopikisana nawo. Kusiyana sikunali kupanga. Anali as-cast microstructure.
Zinayi Zosakambirana mu AISI 8620 Investment Casting Factory
Osati onse oyambitsa amachitira AISI 8620 mwamphamvu mofanana. Izi ndi zomwe zimalekanitsa kuthekera kofunikira kwambiri ndi zomwe zimatuluka:
- Raw material traceability mpaka kutentha nambala- palibe kusakanikirana kwa batch. Ingot iliyonse ya AISI 8620 imatsimikiziridwa ndi ASTM A304, yokhala ndi malipoti athunthu a Ni (0.4-0.7%), Cr (0.4-0.6%), ndi Mo (0.15-0.25%). Kupatuka kunja kwa ± 0.03% kumayambitsa kudzipatula.
- Ma protocol owumitsa zipolopolo adasinthidwa kukhala mame, si nthawi. Chinyezi pamwamba pa 45% RH panthawi ya dewaxing imayambitsa micro-porosity mu 5-12 µm range-osawoneka ndi X-ray koma zoopsa chifukwa cha kutopa. Ma kilns athu amalowetsa RH yeniyeni ndi kutentha masekondi 90 aliwonse.
- Pre-carburizing stress relief pa 650 ° C kwa maola 4-osati kusankha. Kupanikizika kosalekeza kumasokoneza magiya panthawi yowumitsa. Timatsimikizira kupsyinjika kotsalira kudzera pakubowola mabowo pazitsanzo za nkhani yoyamba.
- CMM-based as-cast kuyendera pamaso pa makina aliwonse. Timayang'ana ma callout 12 ofunikira a GD&T - kuphatikiza mawonekedwe amtundu wa m'mbali mwa mano a giya ndi kulolerana kwaubwenzi wapamaso - pagawo lobiriwira. Ngati izo zikulephera apa, palibe kuchuluka kwa CNC kukonza amapulumutsa gawo.
Kumene Ma Factory Standard Amadula Ngodya—ndi Momwe Ife Sitichitira
Mafakitole ena opangira ndalama a AISI 8620 amalumpha kupukuta kwa alloy pre-alloy vacuum, poganiza kuti machitidwe a EAF amasungunula akukwanira. Koma zomwe zili ndi okosijeni pamwamba pa 20 ppm zimapanga zolumikizira za oxide zomwe zimayambitsa kubowola mano. Timagwiritsa ntchito kuyengetsa kwa VIM + ESR pamayendedwe onse apamlengalenga ndi magalimoto - kuchepetsa O₂ mpaka <8 ppm ndi sulfure ku <0.002%. Njira ina yachidule yodziwika: kugwiritsa ntchito zokutira zipolopolo zamtundu uliwonse m'malo mwa zircon-based slurries zokongoletsedwa ndi zitsulo zokhala ndi aloyi wapamwamba kwambiri. Zovala za generic zimathamanga pa 1400 ° C, ndikuyambitsa zophatikizika. Kupangidwa kwathu kwa slurry kumaphatikizapo 12% yophatikizika silika binder ndi kagawo kakang'ono kamene kamatsimikiziridwa ndi laser diffraction - batch iliyonse.
Makasitomala nthawi zambiri amafunsa kuti: "Kodi mutha kugwira ± 0.025 mm pa 120 mm phula m'mimba mwake?" Inde, koma kokha ngati kusinthika kwa khoma kwa giya kopanda kanthu kumakhala mkati mwa ± 0.3 mm. Ichi ndichifukwa chake akatswiri athu opanga zida amayendetsa kayeseleledwe kolimba (pogwiritsa ntchito MAGMASOFT®) * asanavomerezedwe. Timayika ma gradient otenthetsera pamtengo wonse woponyera, kenaka timasintha mazenera kuti tichotse malo otentha. Kotala yatha, izi zidalepheretsa magiya 37 pa dongosolo limodzi la msonkhano wa hybrid axle.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Zochokera ku Qingdao, QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwiritsa ntchito malo ovomerezeka a ISO 9001 pomwe AISI 8620 kuponya ndalama sikuli pawokha - imaphatikizidwa. Makina a CNC amachitika pamalo omwewo, ndikugawana malupu a CMM. Pamene giya yopanda kanthu ibwera kuchokera kuponyedwa, geometry yake yeniyeni imadyetsa mwachindunji chiwongola dzanja cha pulogalamu ya CNC-palibe cholowera pamanja. Ndondomeko zochizira kutentha zimalumikizidwa ndi kuponya manambala mu MES yathu, chifukwa chake magawo a carburizing amadzisintha okha kutengera zotsatira za kuuma kwam'mbuyomu kuchokera kutentha komweko.
Sitigulitsa magawo. Timapereka kukonzekera kogwira ntchito. Izi zikutanthauza kutsimikizira ma mesh a gear ndi optical profilometry asanatumizidwe. Zimatanthawuza kupereka ma cert athunthu, zolemba zomangira zipolopolo, ndi ma micrograph ochiritsa pambuyo pa kutentha akafunsidwa. Zimatanthawuza kukhala ndi ma AISI 8620 master alloys kuchokera kwa ogulitsa atatu ovomerezeka - kotero kusokonezeka kwa mayendedwe sikumachedwetsa dongosolo lanu lachiwonetsero.
Fakitale yopanga ndalama ya AISI 8620 imapeza chidaliro osati kudzera m'mabuku, koma kudzera mu kubwerezabwereza: kuuma komweko kumagawo 500, moyo wotopa womwewo pazaka zitatu zopanga, kukhazikika kofananako pambuyo pa matenthedwe 10,000. Ndiwo muyezo wa QINGDAO QIANGSENYUAN TECHNOLOGY amakumana - osati mwa apo ndi apo, koma mwadongosolo. Chifukwa mu zida zolondola komanso zogwiritsa ntchito zamagalimoto, "pafupi mokwanira" kulibe. Ndi ndendende basi.
