Pamene mainjiniya amatchula a steelcasting foundry fakitale, sikuti amangoyitanitsa zitsulo-akudzipereka kuti azikhala okhazikika pansi pa 300 bar, microstructure integrity pambuyo pa njinga yamoto yotentha, ndi zero kulolerana kwa porosity m'madera ovala kwambiri. Tawona ma projekiti ambiri akuchedwa chifukwa oponya katundu adatenga zitsulo ngati "zitsulo zina." Sizili choncho. Zitsulo zochepa za alloy zimasweka pansi pa kuzimitsidwa kofulumira. Magiredi osapanga dzimbiri ngati CF8M alekanitsa ngati mitengo yozizirira ya nkhungu imayenda ndi ± 5°C. Ndipo magawo a pampu opangidwa ndi cobalt - makamaka AMS 5387 kapena T800 - amafuna kupitiliza kwazitsulo pa kutentha kulikonse, osati kungotsatira pepala.
Chifukwa Chake Kuponyera Chitsulo Kumalephera Kumakina Ngakhale Kuyamba
Zolephera zambiri zimayambira pa mipata itatu yomwe ingathe kupeŵeka: kusonkhanitsa zinthu popanda chiphaso cha batch-level, kapangidwe ka nkhungu yamchenga yomwe imanyalanyaza kulimba kwa magawo ang'onoang'ono, ndi ndondomeko zochizira kutentha zomwe zasiyanitsidwa ndi gawo lenileni la geometry. Pamalo athu a Qingdao, timayesa ma billets a 316L omwe akubwera kuti apeze zomwe zili ndi ferrite * tisanathire * - osati pambuyo. Timayika ma gradients mumchenga pogwiritsa ntchito ma thermocouples ophatikizidwa panthawi yoyeserera. Ndipo sitigwiritsanso ntchito kupsa mtima komweku ku nyumba yapampu ya pistoni ya 45-kg ndi 2.3-kg pressure valve body. Kukula kumodzi sikukwanira kalikonse pakupanga chitsulo cholondola.
Ichi ndichifukwa chake timaphatikizira kukonza njira zopangira kuwunika kwa GD&T. Wogula akatumiza chojambula cha nyumba ya silinda yachitsulo chosapanga dzimbiri yokhala ndi ± 0.05 mm kulolerana pamabowo asanu ndi limodzi okwera, sitimangotchula makina. Timafunsa kuti: khomo limalowa kuti? Ndi ma prints amtundu wanji omwe angasinthe panthawi ya shakeout? Kodi kupotoza kwa post-cast kumachitika bwanji pa 650 ° C? Awa si mafunso ongoganizira chabe. Amayezedwa-pazithunzi zenizeni, ndi data ya CMM yolumikizidwa ndi malo oyambira a CAD.
Kuphatikiza Koyima Komwe Kumawongolera Kusintha
Kutulutsa kunja, kenako kukonza makina, kenako kumaliza kumapanga ma handoffs atatu - ndi mwayi atatu wa zolakwika zochulukirapo. Zathu steelcasting foundry fakitale imayendetsa ndalama ndikuponya mchenga *m'nyumba yomweyi yovomerezeka ndi ISO* komwe malo a CNC amagwira ntchito. Pulagi ya cobalt-nickel yoponyedwa pa 1,420 ° C imasuntha molunjika mpaka kufupikitsa kupsinjika, kenako kupita ku ma axis asanu - zonse mkati mwa maola 48. Palibe zoyendera pakati pa malo. Palibe kukonzanso. Palibe maumboni otayika.
Izi sizothandiza - ndikuwongolera koyendetsedwa ndi fizikisi. Kusiyana kwakukula kwa kutentha pakati pa mchenga wa nkhungu, chitsulo chosungunula, ndi mbale zomangika kumachepetsedwa pamene masitepe onse achitika pansi pa denga limodzi ndikuwunika momwe chilengedwe chimakhalira. Timatsata chinyezi ndi kutentha kozungulira ola lililonse - osati chifukwa "kuchita bwino," koma chifukwa tinayeza momwe 3% RH swing imasinthira nthawi yowumitsa nkhungu kuti isinthe kuuma kwa nkhope pankhope zomata kwambiri.
- CNC-makina zitsulo castings: ≤0.015 mm mawonekedwe apatuka pa 300 mm spans
- Sand-cast carbon steel (WCB): kusinthasintha kwamphamvu kwamphamvu <± 8 MPa kutenthetsa 10 motsatizana
- Investment-cast Stainless (CF3M): Ra ≤1.6 µm ngati-ponyera pamalo oyenda-palibe mphero yachiwiri yofunika
- AMS 5387 cobalt alloy: kuwunika kwathunthu kwa kutentha mpaka kutentha, kuphatikiza chipika chosungunuka, kusanthula kwazithunzi, ndi kutsimikizira kukula kwambewu pa ASTM E112
Zochitika Zenizeni Zapadziko Lonse, Osati Kungotsatira Mapepala
Otsatsa ena amatumiza zitsulo zokhala ndi "ISO 9001 certified" zomwe zidasindikizidwa pamndandanda wazonyamula - koma sangatulutse lipoti limodzi lovomerezeka lowonetsa kuuma kwa maziko apampu a 120-mm. Ife timatero. Chilichonse chomwe chatumizidwa chimakhala ndi lipoti loyeserera (MTR) lomwe limachulukirachulukira, kukolola, kufutukuka, ndi kukhudzika kwake—kuyezedwa ndi makuponi odulidwa *kuchokera kumayendedwe komweko*, osati kuchokera pagawo loyesa lapadera.
Timatsimikiziranso magwiridwe antchito tisanatumize. Winch center shaft roller sikuti amangoyang'ana kukula kwake. Imazungulira pa 1,200 rpm pamakina athu olemetsa-dynamometer pomwe ma gauges amtundu amawunika kupotoza pamalo atatu ozungulira. Nyumba yopumira ya valve sikungodutsa mayeso a hydrostatic pa 1.5 × kugwira ntchito. Imazungulira maulendo 5,000 ndi kutenthedwa kofanana ndi kutentha, 200 ° C mpaka 25 ° C mkati mwa masekondi 90 - ndiyeno imayang'aniridwa ndi utoto. Ngati itasweka, timapanganso makina okwera - osati njira ya NDT.
Zomwe Muyenera Kufuna Kwa Mnzanu Woponya Zitsulo
Osakhazikika pa "timaponya zitsulo." Funsani m'malo mwake:
- Kodi mungandiwonetse zipika zitatu zomaliza za kutentha kwanu kwa ASTM A216 Grade WCB-ndikutsimikizira kuti zonse zidachokera ku mphero imodzi?
- Kodi mumatengera kulimba mu MAGMAsoft kapena zofananira musanavomereze kapangidwe ka nkhungu?
- Kodi kuyendera kwanu komaliza kukuchitika pa CMM yokhazikika-kapena ndi ma micrometer ogwidwa pamanja ndi ma go/no-go gages?
- Kuponya kukalephera kuyang'anitsitsa, kodi mumachichotsa-kapena kusanthula zomwe zidayambitsa pamtundu wophatikizika, kugawa kwa gasi, ndi kusiyana kwapakati pa mkono wa dendrite?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. amayankha kuti inde onse anayi. Osati monga zonena zamalonda - koma monga njira zolembedwera, zowonekera m'marekodi athu opanga ndikutsimikizirika pakuwunika kwamakasitomala. Timamanga zitsulo zazitsulo zama hydraulic systems zomwe zimayenda maola 18,000 popanda kusindikiza chisindikizo. Kwa mapampu akumalo opangira mafuta onyamula madzimadzi odzaza ndi H₂S pa 120°C. Kwa mainjiniya owongolera magalimoto akukweza katundu wa matani 8.5 m'malo ochepera zero. Kudalirika si chandamale. Ndiwo zotsatira za njira zoyendetsedwa-zoyesedwa, zobwerezabwereza, zotsimikiziridwa.
Ngati dongosolo lanu lotsatira lazitsulo likufuna kupitilira muyeso - ngati likufuna kulosera zam'mapangidwe, kusasinthika kwazitsulo, ndi kutsimikizira magwiridwe antchito - yambani ndikuwonetsa poyera. Osati timabuku. Osati ziphaso zokha. Koma kupeza nthawi yeniyeni yoponya zipika, ma chart a kutentha kutentha, ndi malipoti a CMM. Ndi momwe a steelcasting foundry fakitale imapeza malo ake mumayendedwe ofunikira kwambiri.
