Pa Disembala 20, mtolankhaniyo adamva kuchokera ku China Iron and Steel Research Group Gaona Company kuti kampaniyo idatsogolera popanga limodzi Fushun Special Steel ndi Erzhong Wanhang koyamba m'masiku aposachedwa kuti ayesere bwino kupanga superalloy turbine disk integral die forging yayikulu kwambiri mdziko langa pakadali pano—— Ma GH4706 alloy turbine disk forgings akuluakulu kwambiri, oyenera kugwiritsidwa ntchito kutentha kwambiri kwa madigiri 650 Celsius, okhala ndi mphamvu ya 1200 MPa, kulemera kwa matani 13.5, ndi mainchesi a 2380 mm, adaswa ulamuliro wakunja.
Malinga ndi Zhao Guangpu, mtsogoleri wa polojekiti yofufuza komanso wachiwiri kwa director wa Steel Research Gona Science and Technology Committee, ma turbine a gasi olemera kwambiri a malo akuluakulu opangira magetsi ali ndi zabwino zazikulu monga mphamvu zambiri, kutentha kwambiri, kuchuluka kochepa komanso kulemera kochepa, komanso kuipitsidwa kochepa. Ukadaulo wake wopanga zinthu wakhala gawo laukadaulo wapadziko lonse. Chimodzi mwa zizindikiro zofunika kwambiri za mphamvu yonse ya dziko. Zigawo zake zazikulu zotentha ndi diski imodzi ndi ziwiri (ma disc ndi ma guide a turbine, masamba ogwirira ntchito), zomwe zimagwira ntchito ngati "mtima" wa anthu. Ndi ukadaulo wofunikira kwambiri popanga ma turbine a gasi komanso choletsa malo a ma turbine olemera. Ma disk a turbine a gasi olemera amafunika maola opitilira 100,000 a ntchito yayitali yotentha kwambiri komanso yopsinjika kwambiri, ndipo amafunikira zinthu zapamwamba kwambiri, monga kapangidwe ka zinthu kofanana, koyera, kosalala, komanso kokhazikika; Kukula kwake kwakukulu, ndipo m'mimba mwake ndi malo owonetsera ndi motsatana. Imafika mamita opitilira 2.2 ndi 4.2 masikweya mita, yomwe ndi nthawi 4 kuposa m'mimba mwake wa disk ya turbine ya injini ya aero, nthawi 10 kuposa malo owonetsera, ndi nthawi 60 kuposa kulemera, ndi zina zotero. Ukadaulo waukulu wopanga ma disk a superalloy turbine akuluakulu wakhala akutsekedwa kwambiri kunja kwa dziko ndipo wakhala ukulamulidwa ndi mayiko akumadzulo kwa nthawi yayitali.
Pachifukwa ichi, Zhao Guangpu anatsogolera gulu la polojekitiyi kuti lichite kafukufuku woyambira ndi kafukufuku waukadaulo, ndipo potsiriza anagwiritsa ntchito ukadaulo wapamwamba kwambiri wapadziko lonse lapansi wa "kusungunula katatu + kusokoneza mobwerezabwereza + kusokoneza kawiri + kusungunula kamodzi kokha" kuti agwiritse ntchito Miyezo yapadziko lonse lapansi, kudutsa malire aukadaulo wa kukonzekera kwakukulu kwa disk ya superalloy turbine disk komwe kunakumana nako panthawi yopanga, monga ukadaulo wosungunula katatu wochepa wa ingots zazikulu zachitsulo zokhala ndi ingots zolemera matani oposa 18, ndi ukadaulo wobwerezabwereza wosokoneza ndi wophukira bwino wa tirigu wabwino kwambiri wa mipiringidzo yayikulu yokhala ndi mainchesi 1000 mm, yokhala ndi mainchesi 2200 Integral die forging ndi ukadaulo wowongolera kutentha kochepa wa zigawo zazikulu za mbale zazikulu kuposa mamilimita. Gulu la polojekitiyi linachita kafukufuku wodziyimira pawokha ndi chitukuko komanso luso loyambirira la zolakwika zachitsulo monga kuchuluka kwa Nb kwambiri kwa chinthu chopangira mu superalloy ya GH4706, yomwe imakonda kukhala ndi mawanga akuda komanso kusiyana kwa malo oyera. Zigawo zofunika kwambiri za ma turbine olemera a gasi mdziko langa ndi "khosi losweka", zomwe zatsegula njira yokonzekera ma disks akuluakulu a superalloy turbine okhala ndi mawonekedwe aku China okhala ndi ufulu wodziyimira pawokha waukadaulo.
Pambuyo pa kapangidwe ka thupi, magwiridwe antchito a turbine disc afika pa zofunikira zaukadaulo za alloys ofanana akunja, ndipo zotsatira zake zazikulu zapezeka. Ichi ndi chitukuko china chofunikira chomwe dziko langa lapanga pankhani ya ma superalloys ofooka, chomwe chapangitsa kuti ukadaulo wokonzekera ma turbine disks akunyumba ufike pamlingo wotsogola padziko lonse lapansi. Pa Disembala 8, msonkhano wowunikira mfundo zazikulu za GH4706 alloy full-size roulette forgings unachitikira ku Beijing. Akatswiri adapereka kuwunika kwakukulu, zomwe zikutanthauza kuti sitepe yolimba yatengedwa kuti igwiritsidwe ntchito bwino turbine disk.
