Akatswiri akamatchula chitsulo chosapanga dzimbiri cha 310S cha ng'anjo ya ng'anjo, manifolds otulutsa mpweya, kapena ma valve otenthetsera kwambiri, samangosankha chinthu - akubetcha pa kukhazikika kwa microstructure pamwamba pa 1,000 ° C. Koma izi ndi zomwe magulu ambiri ogula zinthu amapeza mochedwa: si fakitale iliyonse yazitsulo zosapanga dzimbiri ya 310S yomwe imapereka kapangidwe kake kambewu, kagawidwe ka carbide, kapena kukana kutopa kwamafuta - ngakhale ndi ziphaso zofanana za mphero.. Tawonapo kutentha kwa 310S kuphulika pambuyo pa 200 kuzungulira 1,150 ° C-osati chifukwa cha mapangidwe, koma chifukwa chakuti kusiyana kwa as-cast dendritic sikunakhazikitsidwe kwathunthu musanayambe njira yothetsera.
Chifukwa Chake Kusasinthika Kwazinthu Kufunika Kwambiri Kuposa Ziphaso Zogaya Zokha
Lipoti loyesa mphero limatsimikizira kupangidwa mwadzina. Zimatero ayi tsimikizirani kugawa yunifolomu ya chromium-nickel pakhoma la 400-mm-thick casting. Popanga zinthu zenizeni padziko lapansi, tayeza mpaka 8% kuchepa kwa Cr m'malo osakanikirana a mchenga wa 310S - zokwanira kuyambitsa okosijeni komweko pa 1,050 ° C. Ichi ndichifukwa chake ogwiritsa ntchito otsogola tsopano amafuna zipika zochizira kutentha, osati kungosanthula mankhwala. Fakitale yabwino kwambiri yazitsulo zosapanga dzimbiri ya 310S imaphatikiza kuponyera, kuwongolera njira, ndikuchepetsa kupsinjika m'njira imodzi yoyendetsedwa - palibe zotenthetsera zakunja zakunja, palibe ma handoffs. Pamalo athu ku Qingdao, malo aliwonse a 310S amalowetsedwa kawiri: choyamba pa 1,060 ° C pakusungunuka kwathunthu kwa carbide, kenako kuzirala pang'onopang'ono mpaka 750 ° C ndikutenthedwanso mpaka 920 ° C kuti spheroidize sigma gawo lotsalira. Izi sizomwe zimachitika - ndi momwe timagwirizira chiwopsezo cha dzimbiri pansi pa 0.02 mm / chaka pakuwonetsa kutentha kwapang'onopang'ono.
Maluso Atatu Osakambirana Amene Muyenera Kutsimikizira
Musanavomereze fakitale ya zitsulo zosapanga dzimbiri ya 310S, tsimikizirani kuti izi zitha kuchitika patsamba, osati kudzera pa imelo:
- Kutsimikizira kwazitsulo zapansi: Kodi amayendetsa optical emission spectroscopy (OES) pa kutentha kulikonse? Kodi angakoke chitsanzo kuchokera pagawo lakuda kwambiri la kujambula kwanu - osati othamanga okha?
- Analamulira mpweya kutentha mankhwala: Kodi kuyatsa kumachitidwa mu ng'anjo zosakaniza za nayitrojeni-hydrogen wokhala ndi mame ≤ -40°C? Kutuluka kwa mpweya panthawi yozizira kumapanga sikelo ya chromium oxide yomwe imalepheretsa kukana kwanthawi yayitali.
- Dimensional kukhazikika kutsimikizira: Kwa magawo opitilira 300 mm, amayesa tsamba lankhondo pambuyo kutentha mankhwala-osati kokha pambuyo makina? Takonza uta wa 0.8 mm mu mphete yoyatsira ya 310S popotoza dongosololo, kenako ndikutsimikizira ndi laser tracker post-anneal.
Kumene Makatalogu Wamba Amalephera—ndipo Uinjiniya Wamwambo Upambana
Ma flanges a 310S akutali amagwira ntchito bwino pa 850 ° C. Koma pamene ntchito yanu ikufuna 1,100 ° C kupalasa njinga ndi ma syngas odzaza sulfure, zodziwika bwino zimasokonekera. Ndi pamene mukusowa mnzanu yemwe amachitira chemistry ngati poyambira-osati mzere womaliza. Kwa makasitomala aku Europe omwe amamanga mavavu a biomass gasifier, tidasintha kusungunuka kwa 310S: kukweza silicon mpaka 1.8% kuti tithandizire kukana kwa slag, kutsitsa manganese mpaka 0.4% kupondereza mapangidwe a delta-ferrite, ndikuwonjezera 0.15% cerium kuti tikhome malire a tirigu. Zotsatira: 3.2× moyo wautali wautumiki motsutsana ndi ASTM A297 Gulu HK40. Palibe chiphaso chomwe chimakwaniritsa izi - koma kuyesa kwenikweni kumatero.
Zomwe Muyenera Kufunsa Musanatumize PO Yanu Yoyamba
Osafunsa "Kodi mutha kupanga 310S?" Funsani m'malo mwake:
- "Ndiwonetseni mamapu atatu omaliza a EDS a 310S okhuthala kuposa 250 mm - makamaka mawonekedwe pakati pa chokwera ndi kuponya."
- "Kodi nthawi yanu yochuluka yotani pakati pa shakeout ndi njira yothetsera nyumba ya 120-kg 310S?" (Yankho liyenera kukhala ≤ maola 4)
- "Kodi mumasunga zitsanzo zolimba kuchokera ku kutentha kulikonse - ndipo ndingapemphe zomwe Charpy zimakhudza pa 1,000 ° C?"
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. imasunga kutsata kwathunthu kuchokera pa ladle log mpaka lipoti lomaliza la CMM. Dongosolo lililonse la 310S limaphatikizapo ma cert, ma chart ochizira kutentha, ndi zithunzi za metallographic za gawo lokhuthala kwambiri - lopezeka musanatumizidwe. Malo awo ogwirizana ndi ISO amayendetsa ndalama ndi kuponya mchenga mbali ndi mbali, kuwalola kusankha njira yomwe imachepetsa kutsika kwa kutentha m'madera ovuta. Kwa ma geometri ovuta ngati manifold otulutsa ma doko angapo, amagwiritsa ntchito makina osakanizidwa oponyera: mawonekedwe owoneka bwino apafupi ndi ukonde, kenako makina osindikizira a CNC mpaka ± 0.05 mamilimita pambuyo pothetsa kupsinjika-kuchotsa kupotoza kwa pambuyo pa kutentha.
Yang'anani Kupitilira Chiphaso-Yang'anani Pamalo Ophwanyika
Kuyesa kowona kwa fakitale yachitsulo chosapanga dzimbiri ya 310S si zolemba zake. Zili ngati malo ake osweka akuwonetsa mbewu zoyera, zofananira - osati ma dendrites osudzulana kapena maukonde a sigma-phase. Mukalandira chitsanzo chanu choyamba, pemphani chopukutidwa chodutsa pakhoma lolemera kwambiri. Pansi pa kukula kwa 100×, muyenera kuwona kukula kwambewu zofananira (ASTM 4–6), ziro intergranular cracking, ndipo palibe mabandi atha chromium. Ndilo siginecha ya wogulitsa yemwe amachitira 310S osati ngati chitsulo chamtengo wapatali-koma monga gawo lolondola la matenthedwe. Pamene ntchito zapadziko lonse zikukwera kutentha, kusiyana kumeneku kumalekanitsa mabwenzi odalirika ndi kuwerengeranso kokwera mtengo. Nthawi ina mukatchula 310S, musangoyang'ana pepala. Onani microstructure.
