Pa Disembala 20, mtolankhaniyo adamva kuchokera ku China Iron and Steel Research Group Gaona Company kuti kampaniyo idatsogola popanga pamodzi Fushun Special Steel ndi Erzhong Wanhang kwa nthawi yoyamba m'masiku aposachedwa kuti ayese bwino kupanga diski yayikulu kwambiri ya turbine turbine disk. kufa ndikuchita m'dziko langa pakali pano—— Zopangira diski zazikulu kwambiri za GH4706 alloy turbine disk, zoyenera kugwiritsidwa ntchito pansi pa kutentha kwa madigiri 650 Celsius, zokhala ndi mphamvu ya 1200 MPa, kulemera kwa matani 13.5, ndi m'mimba mwake 2380 mm, adaphwanya ulamuliro wakunja.
Malinga ndi a Zhao Guangpu, mtsogoleri wa polojekitiyi komanso wachiwiri kwa mkulu wa Steel Research Gona Science and Technology Committee, makina opangira gasi olemetsa opangira magetsi akuluakulu ali ndi zabwino zambiri monga mphamvu zambiri, kutentha kwambiri, voliyumu yaying'ono komanso kulemera kwake, ndi kuipitsa kochepa.Ukadaulo wake wopanga wakhala gawo laukadaulo wadziko lonse., Chimodzi mwa zizindikiro zofunika za mphamvu zonse za dziko.Zigawo zake zapakati zotentha ndi diski imodzi ndi ziwiri (ma turbine discs ndi malangizo, masamba ogwirira ntchito), omwe amakhala ngati "mtima" wa anthu.Ndiwo ukadaulo wofunikira pakupangira ma turbine a gasi komanso cholepheretsa kufalikira kwa ma turbines olemera a gasi.Ma disks a turbine turbine disks olemera kwambiri amafunikira maola oposa 100,000 a nthawi yayitali yotentha kwambiri komanso yopanikizika kwambiri, ndipo amafunikira zitsulo zapamwamba kwambiri zazitsulo, monga homogeneous, zoyera, zokongoletsedwa bwino, zokhazikika ndi ntchito;Kukula kwakukulu, ndi m'mimba mwake ndi malo owonetserako ndi motsatana Imafika mamita oposa 2.2 ndi mamita 4.2, omwe ndi 4 nthawi 4 m'mimba mwake mwa diski ya injini ya aero, nthawi 10 malo omwe akuyembekezeredwa, ndi kulemera kwa 60, ndi zina zotero. .Ukadaulo wapakatikati wopangira ma disks amtundu wa superalloy turbine disk wakhala ukutsekeredwa kunja ndipo wakhala akulamulidwa ndi mayiko aku Western kwa nthawi yayitali.
Kuti izi zitheke, Zhao Guangpu adatsogolera gulu la polojekitiyi kuti lichite kafukufuku woyambira komanso kafukufuku waukadaulo, ndipo pamapeto pake adatengera ukadaulo wapamwamba kwambiri wapadziko lonse lapansi wa "kusungunuka katatu + kukhumudwitsa mobwerezabwereza + kukhumudwitsa kawiri + moto umodzi wokha wonse kufa" ukadaulo wokonzekera kukhazikitsa. Miyezo yapadziko lonse lapansi, kuphwanya luso la kukonza disk lalikulu la superalloy turbine disk zomwe zidakumana panthawi yachitukuko, monga ukadaulo wosungunulira magawo atatu azitsulo zazikulu zokhala ndi ma ingots olemera matani 18, ndikusokoneza mobwerezabwereza ndi mbewu zabwino. ukufalikira luso mipiringidzo lalikulu ndi awiri a 1000 mm, ndi awiri a 2200 Integral kufa forging ndi otsika-kutentha kupanga ndi luso gulu ulamuliro mbali yaikulu mbale zazikulu kuposa millimeters.Gulu la polojekitiyi lidachita kafukufuku wodziyimira pawokha komanso chitukuko komanso luso loyambirira lazowonongeka zazitsulo monga kuchuluka kwambiri kwa Nb zomwe zili mu alloying element mu GH4706 superalloy, yomwe imakonda kukhala ndi mawanga akuda komanso tsankho loyera.The kiyi otentha-mapeto zigawo zikuluzikulu za dziko langa lolemera mpweya turbines ndi "anamamatira khosi", amene anatsegula njira njira yokonza lalikulu opunduka litayamba superalloy turbine ndi makhalidwe Chinese ndi ufulu wodziimira nzeru katundu.
Pambuyo pa anatomy, magwiridwe antchito a turbine disc adafika pazofunikira zamakina amitundu yofananira yakunja, ndipo chotsatira chachikulu chakwaniritsidwa.Ichi ndichinthu china chofunikira kwambiri chomwe dziko langa lapanga pankhani ya ma superalloys opunduka, omwe adayendetsa ukadaulo wokonzekera ma disks apanyumba apamwamba kwambiri kuti afike pamlingo wotsogola padziko lonse lapansi.Pa Disembala 8, msonkhano waukulu wowunikiranso za GH4706 alloy alloy full size roulette forging unachitikira ku Beijing.Akatswiri anapereka kuwunika kwakukulu, zomwe zikutanthauza kuti sitepe yolimba yatengedwa kuti igwiritse ntchito kwenikweni diski ya turbine.
