Fakitale iliyonse yopangira zitsulo imayamba ndi funso lomwelo: Kodi mumatembenuza bwanji chitsulo chosungunula kukhala gawo lomwe silingaphwanyike pansi pa 300 bar of hydraulic pressure-kapena kupulumuka maola 10,000 mu ntchito ya gasi wowawasa? Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., taponyera ndi makina opitilira 12,000 mavavu okakamiza, nyumba zapampu za pisitoni, ndi ma nozzles a aloyi a cobalt kuyambira 2015. Tawona nkhungu zamchenga zimalephera kutentha kwa 1,150 ° C. Tachotsa 47% ya gulu la AMS 5387 pambuyo pakuwunika kwa microstructure kuwululira tsankho la interdendritic. Izi si nkhani zamabuku-ndizosankha zatsiku ndi tsiku zomwe zimatanthauzira maziko a fakitale yoponya zitsulo ntchito.
Umphumphu Wazinthu Simaganiziridwa - Watsimikiziridwa
Simungathe kuponya zida zogwira ntchito kwambiri kuchokera ku "zitsulo zosapanga dzimbiri zosapanga dzimbiri." Pamalo athu a Qingdao, kutentha kulikonse kwa T800 cobalt-based alloy kumabwera ndi malipoti oyesa mphero - ndipo timayesanso za carbon, chromium, ndi tungsten tisanasungunuke. Chifukwa chiyani? Chifukwa kupatuka kwa 0.03% mu cobalt kumasintha kutentha kwa solidus ndi 12 ° C. Izi zikusintha mitengo yozizira ya nkhungu. Izi zimakhudza kukula kwa tirigu. Izi zimasokoneza moyo wotopa mu ma roller a winch center shaft. Timagwiritsa ntchito OES (Optical Emission Spectrometry) pamipiringidzo yomwe ikubwera ndikutsimikizira ASTM A957 pakupanga ndalama, ASTM A159 yachitsulo chotuwira, ndi AMS 2269 ya aloyi a cobalt-nickel. Palibe kuchotserapo. Osati "kukhulupirira koma tsimikizirani" - timatsimikizira poyamba, kenako ndikuponya.
Kuponya Njira Kusankha Kumatengera Kutha Kwagawo
Kuponyera mchenga kumagwira maziko akuluakulu a pampu okwana 1,800 kg-koma amafuna kuwongolera mwamphamvu zomangira kuti zisawonongeke m'mitsempha ya ma silinda opyapyala. Kuponya ndalama kumapereka ± 0.05 mm dimensional kubwereza kwa mapulagi a AMS 5387 cobalt alloy-koma kumafunikira chipukuta misozi chokhazikika cha sera. Sitisankha njira imodzi ndikukakamiza magawo onse. M'malo mwake, timapanga chigawo chilichonse molingana ndi mfundo zitatu: chiŵerengero cha makulidwe a khoma, kufunikira kwa mapeto (Ra ≤ 1.6 µm vs. Ra ≤ 6.3 µm), ndi njira yolemetsa yogwira ntchito. Mwachitsanzo, ma hydraulic pressure valve valve body amagwiritsa ntchito mchenga ku chipolopolo chake chakunja-koma mafunde amkati ndi CNC-machined post-cast kuti agwire kulolera kwa GD&T molimba kuposa ± 0.025 mm. Njira yosakanizidwa imeneyo siisankha. Ndimomwe mumakumana ndi ISO 8502-3 zaukhondo *ndi* ASME B16.34 ratings.
Kukhazikika Kwamawonekedwe Kumayamba Nkhungu Isanatsanulidwe
Nthawi ina tinalandira chojambula cha nyumba ya pampu ya pisitoni yokhala ndi ma bore 12 ovuta-zonse zotchulidwa ± 0.015 mm. Makasitomala amayembekezera makina omaliza mpaka kumaliza. Koma kutsika kwamafuta mu chitsulo cha ductile kumasiyanasiyana malinga ndi makulidwe a gawo. Khoma la 45-mm limachepa 0.28% kuposa nthiti ya 22-mm. Chifukwa chake tidapanga zilolezo zocheperako pazida zachitsanzo-osati ngati zosinthira zokhazikika, koma monga ma curve a parametric omwe amamangiriridwa ku nthawi yolimba yapanyumba (yowerengeredwa kudzera pa MAGMAsoft simulation). Kenako tidatsimikizira machitidwe ocheperako ndi kuyesa kopereka nsembe, kuyeza pa Zeiss PRISMO CMM. Pokhapokha m'pamene tinavomereza kuyendetsedwa kwa kupanga. Ichi ndichifukwa chake kuwunika kwathu pakuwunika kumaphatikizapo kuyeza kolumikizana kwa 100% pazigawo zitatu: monga-cast, pambuyo pa kupsinjika, komanso kukonza pambuyo. Kutsatiridwa si lipoti - ndi nambala yojambulidwa ndi laser yolumikiza gawo lililonse ndi chipika chake chosungunula, njira yopangira kutentha, ndi lipoti lomaliza la CMM.
Kuwongolera Kwabwino Kumapangidwa mu Njira Iliyonse Yogwirira Ntchito
Mafakitale ena amachitira QC ngati chipata kumapeto. Timaziyika pamene zalephera: risiti yazinthu zopangira, kusonkhanitsa nkhungu, kuyang'anitsitsa kutentha, nthawi yogwedeza, ndi kufufuza kuuma kwa kutentha kusanayambe. Oyang'anira athu amagwiritsa ntchito mfuti zonyamulika za PMI kuti atsimikizire kalasi ya aloyi asanatulutse-ndi kuyesa kwa akupanga (ASTM E114) pazitsulo zilizonse zokhuthala pamwamba pa 75 mm. Pazigawo za cobalt-nickel, timawonjezera kuwunika kolowera kwa fulorosenti (ASTM E1417) chifukwa ming'alu yaying'ono imabisala m'malire a dendritic. Ndipo inde - timasunga zolemba zonse pa digito kwa zaka 15. Osati chifukwa muyezo umatero, koma chifukwa chakuti European OEM itatsata kulephera kwa gawo ku gulu limodzi la AMS 5387, tidakoka mbiri yowunikira mumasekondi 83. Palibe zongoyerekeza. Osachedwetsa.
The maziko a fakitale yoponya zitsulo Kupambana kumafika pazitatu zosakambitsirana: kuwongolera zitsulo, kuwoneratu zam'tsogolo kwapadera, ndikuyang'ana mokhazikika pamayendedwe - osatsekedwa kumapeto. Ku QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., zikhazikitso zimenezo si nthanthi. Ndimo momwe timaperekera ma valve opanikizika omwe amagwira ntchito pa 450 ° C popanda kutayikira, nyumba zopopera zomwe zimasungabe kukhazikika pambuyo pa kuzungulira kwa 2 miliyoni, ndi ma nozzles a cobalt omwe amakana kukokoloka kwa mapampu abrasive slurry. Pamene zovuta za hybrid hybrid zikukwera-ndipo miyezo monga NORSOK M-650 ndi API 6A imakhwimitsa-zofunikira sizisintha. Amangofuna kuti aphedwe mozama. Ndiko komwe chidziwitso chimakumana ndi uinjiniya.
