Pamene mainjiniya afotokoza mchenga kuponyera chitsulo chosapanga dzimbiri kwa mavavu othamanga kwambiri a hydraulic kapena nyumba zapampu zakunyanja, sikuti amangosankha njira - akubetcha pa kukhazikika kwa dimensional, kukana kwa dzimbiri, komanso kukhulupirika kwa microstructural pansi pa zovuta zenizeni. Otsatsa ambiri amalonjeza kutulutsa kolondola. Ndi ochepa omwe amapereka ma nozzles a AMS 5387 a cobalt alloy * ndi * zitsulo zosapanga dzimbiri 316 zachitsulo zosapanga dzimbiri kuchokera pamzere womwewo wopangira - popanda kusuntha kwa batch-to-batch mu kapangidwe ka tirigu kapena kulimba kwa pamwamba. Kusasinthika kumeneku kumayamba ndi kutsatiridwa kwa zinthu, osati zonena zamalonda.
Chitsulo Chopanda Mchenga: Kumene Chitsulo Chimakumana ndi Ntchito Yofunika Kwambiri
Chitsulo chamchenga chosapanga dzimbiri sichachikale - chimasankhidwa mwanzeru magawo ake akapitilira 15 kg, amakhala ndi ndime zovuta zamkati, kapena amafunikira chithandizo cha kutentha asanapange makina omaliza. Mosiyana ndi kuponyera ndalama, kuponya mchenga kumagwira zigawo zazikulu zosapanga dzimbiri popanda zipolopolo za ceramic kapena kuipitsidwa kotsalira kwa silika. Koma kupambana kumadalira pa zinthu zitatu zomwe sizingakambirane: zovomerezeka zopangira zopangira (osati ma cert a mphero, komanso malipoti atsatanetsatane), kuwongolera chinyezi chamchenga mkati mwa ± 0.3%, ndikuwongolera kuziziritsa kuti mupewe mapangidwe a sigma m'makalasi awiri.
Tawona makasitomala akukana ma CF8M ambiri chifukwa cha porosity yomwe imapangika pafupi ndi malo olowera pakhomo-ngakhale kuyesa kwa akupanga. Chifukwa chake? Kuthamanga kosagwirizana kwa ramming pamasiteshoni omangira pamanja. Pamalo athu a Qingdao, kukonzekera mchenga ndi nthawi yeniyeni yowunikira kutentha kwa bokosi kumathetsa kusintha kumeneku. Chitsulo chilichonse chosapanga dzimbiri chimagwiritsa ntchito nkhungu zomwe zimatenthedwa kale pa 120-150 ° C, kuchepetsa kutenthedwa kwa kutentha ndikuwongolera kutha kwa Ra 6.3 μm as-cast-kudula nthawi ya post-machining ndi 22% pafupifupi.
Chifukwa Chake Kuphatikizika Kwamakulidwe Kumapambana Otsatsa "Oponya-Okha".
Mafakitale ena amapanga zitsulo zosapanga dzimbiri. Ena amawapanga makina. Ochepa amachita zonse ziwiri-ndipo ochepera amawongolera kutentha ndi kumaliza m'nyumba. Pamene nyumba yanu ya pisitoni pampu yamphamvu imafuna zida za H13 zoyika zitsulo zowongoleredwa m'thupi la CF3M, kenako zowumitsidwa mpaka 48-52 HRC * mutatha * kukonza malo ovuta osindikizira, ma handoffs pakati pa ogulitsa amayambitsa zolakwika zamalumikizidwe, kusokoneza kwa ma oxidation, ndi mbiri zamatenthedwe zosawerengeka.
Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO.,LTD., gulu limodzi limayang'anira ndondomeko yonse: kapangidwe kake → kuumba mchenga wobiriwira → kuthira ng'anjo → kuchepetsa nkhawa → kutembenuka kwa CNC/mphero → chitsimikizo cha CMM → passivation. Tapereka maziko a pampu a 316L pomwe makulidwe a khoma amasiyana mochepera ± 0.15 mm kudutsa 1.2-mita spans - zomwe zimatheka chifukwa metrologist yemweyo amatsimikizira miyeso isanayambe komanso itatha chithandizo cha kutentha pogwiritsa ntchito kafukufuku wofanana wa CMM.
- Kukhazikika kwa dimensional: ≤0.05 mm kupatuka pazinthu zopitilira 300 mm kutalika
- Kuwongolera kwa Microstructure: ASTM A957 Level 2 dendrite spacing yotsimikiziridwa pa batch iliyonse
- Kukhulupirika kwapamtunda: Palibe ming'alu yapansi panthaka yomwe yapezeka kudzera pakuwunika kolowera kwa fulorosenti (FPI) pa 10 × magnification
Zochitika Zenizeni Zapadziko Lonse: Kupitilira Mapepala Odziwika
"Chitsulo chosapanga dzimbiri" sichitanthauza kanthu popanda nkhani. Kuponyedwa kwa 304 kumatha kupulumuka ntchito yamadzi amchere-koma kumalephera mowopsa m'malo opangira mpweya wowawasa chifukwa cha maenje opangidwa ndi chloride. Ichi ndichifukwa chake timayesa kutentha kwachitsulo chilichonse chosapanga dzimbiri polimbana ndi momwe ntchito ikugwiritsidwira ntchito: njinga yopopera mchere kwa ma winch roller akunyanja, kupalasa njinga zotentha kuchokera ku -40°C mpaka +200°C pakupanga ma hydraulic manifolds, ndi kuyerekezera kwa dzimbiri kothamanga kwamafuta & ma valve a gasi.
Chaka chatha, kasitomala waku Europe adafunikira zodzigudubuza zapakati pa shaft zowongolera ma winchi agalimoto omwe amagwira ntchito m'malo amchenga. Wowagulitsa m'mbuyomu adagwiritsa ntchito G-X6CrNi18-10 yokhazikika yokhala ndi kuuma kwa 220 HB - moyo wodzigudubuza umakhala wa maola 470. Tinasinthira ku 1.4408 mchenga-cast (CF3M) yokhala ndi njira yothetsera pa 1050 ° C + kuzimitsa madzi mofulumira, kukwaniritsa 285 HB ndi 32 J zimakhudza kulimba pa -20 ° C. Deta yakumunda ikuwonetsa maola 1,850+ akutanthauza nthawi pakati pa zolephera. Kusiyanitsa sikunali kalasi yakuthupi yokha-kunali kulamulidwa kulimba kwamphamvu ndi kubalalitsidwa kwa carbide.
Kusankha Fakitale Yanu Yazitsulo Zopanda Mchenga: Mafunso Atatu Omwe Amawulula Choonadi
Musanasaine NDA, funsani:
- "Ndiwonetseni malipoti anu omaliza a 316L akutentha - ndi zotsatira zofananira zoyeserera." Ngati akuzengereza, kutsimikizira kwawo kwazinthu kumapangidwa pamapepala, osati kuphatikizika.
- "Kodi mumapewa bwanji kutenga kaboni panthawi yothira?" Ma ladle odetsedwa kapena nthawi yochuluka yokhalamo imatulutsa chromium. Timagwiritsa ntchito vacuum degassing ndi titaniyamu zowonjezera kuti titseke mpweya pansi pa 0.03%.
- "Kodi mayendedwe anu aatali amtundu wanji osapanga dzimbiri popanda kuyenerera ndi chiyani?" Yankho lathu: Magulu 47 a AMS 5387 cobalt alloy alloy pampu - ogwira ntchito omwewo, mchenga womwewo, kutentha kwa ng'anjo komweko.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imagwira ntchito fakitale yopangira zitsulo zosapanga dzimbiri yomangidwa kuti igwire ntchito yobwerezabwereza - osati ma prototypes amodzi. Sitigulitsa ma castings. Timapereka chitsimikizo chogwira ntchito: ma valve opanikizika omwe amasindikiza pa bar 350, nyumba zapampu zomwe zimakana kukokoloka kwa cavitation kwa maola 12,000+, mawotchi omwe amasunga kuuma kwa torsional pambuyo pa maulendo a 50,000. Izi ndi zomwe zimachitika pamene zitsulo, makina, ndi kuwongolera khalidwe zimagawana dongosolo limodzi la pansi-ndi unyolo umodzi woyankha.
