Ngomhla zingama-20 kuZibandlela, intatheli yathola eChina Iron and Steel Research Group Gaona Company ukuthi le nkampani yahola ngokuhlanganyela ekukhiqizeni iFushun Special Steel kanye ne-Erzhong Wanhang okokuqala ngqa ezinsukwini ezisanda kwedlula ukuze kuvivinywe ngempumelelo ukukhiqiza idisk enkulu ye-superalloy turbine disk ebalulekile. die forging ezweni lami njengamanje—— I-GH4706 alloy turbine disk forgings enkulu kakhulu, elungele ukusetshenziswa ngaphansi kwezimo zokushisa eziphakeme ezingama-650 degrees Celsius, nezinga lamandla elingu-1200 MPa, isisindo samathani angu-13.5, nobubanzi obungu-2380 mm, yaphula ukubusa kwamanye amazwe.
Ngokusho kukaZhao Guangpu, umholi wephrojekthi yocwaningo kanye nesekela lomqondisi we-Steel Research Gona Science and Technology Committee, izinjini zegesi ezisindayo zeziteshi ezinkulu zikagesi zinezinzuzo ezivelele njengamandla aphezulu, ukusebenza kahle kokushisa okuphezulu, umthamo omncane nesisindo, kanye nokungcola okuncane.Ubuchwepheshe bayo bokukhiqiza sebuphenduke izinga lobuchwepheshe likazwelonke., Olunye lwezimpawu ezibalulekile zamandla kazwelonke aphelele.Izingxenye zayo eziyinhloko ezishisayo ziyidiski eyodwa nezimbili (ama-turbine discs neziqondiso, ama-blade asebenzayo), asebenza "njengenhliziyo" yabantu.Ziwubuchwepheshe obubalulekile bokukhiqiza izinjini zegesi kanye nomgoqo ovimbela ukwenziwa kwasendaweni kwezinjini zegesi ezisindayo.Amadiski eturbine yegesi esindayo adinga amahora angaphezu kuka-100,000 wesevisi yesikhathi eside yokushisa okuphezulu kanye nengcindezi ephezulu, futhi adinga ikhwalithi ephezulu kakhulu yensimbi yezinto zokwakha, ezifana ne-homogeneous, pure, fine-grained, isakhiwo sempahla ezinzile nokusebenza;usayizi omkhulu, kanye nobubanzi bayo nendawo yokuqagela ngokulandelana Ifinyelela ngaphezu kwamamitha angu-2.2 kanye namamitha-skwele angu-4.2, okuyizikhathi ezingu-4 ububanzi bediski ye-aero engine turbine disk, izikhathi ezingu-10 endaweni ehlongozwayo, nesisindo esiphindwe izikhathi ezingu-60, njalonjalo. .Ubuchwepheshe bokukhiqiza obuyinhloko bamadiski e-superalloy turbine disks buvinjwe ngokuphelele phesheya futhi sebuphethwe amazwe aseNtshonalanga isikhathi eside.
Kuze kube manje, uZhao Guangpu uhole ithimba lephrojekthi ukuthi lenze uchungechunge locwaningo oluyisisekelo kanye nocwaningo lwezobuchwepheshe, futhi ekugcineni wamukele ubuchwepheshe bokulungiselela obusezingeni eliphakeme kakhulu "bokuncibilika kathathu + okuphindiwe + okucasula kabili + + umlilo owodwa jikelele wokubumba" ukuze kusetshenziswe. Amazinga Amazwe Omhlaba, ukwephula ibhodlela lobuchwepheshe lokulungiswa kwediski ye-superalloy turbine disk enkulu okuhlangatshezwene nayo ngesikhathi senqubo yokuthuthukiswa, njengobuchwepheshe bokuncibilikisa obuhlukene kathathu bezinsimbi ezinkulu ezinezingothi ezinesisindo esingaphezu kwamathani ayi-18, nokukhungathekisa okuphindaphindiwe kanye nezinhlamvu ezinhle. ubuchwepheshe obuqhakazayo bemigoqo emikhulu enobubanzi obungu-1000 mm, enobubanzi obungu-2200 Integral die forging kanye nezinga lokushisa eliphansi ukwakha kanye nobuchwepheshe bokulawula inhlangano yezingxenye zepuleti ezinkulu ezinkulu kunamamilimitha.Ithimba lephrojekthi lenze ucwaningo oluzimele kanye nentuthuko kanye nokuqamba okusha kwasekuqaleni kokukhubazeka kwe-metallurgical njengokuqukethwe kwe-Nb okuphezulu kakhulu kwe-elementi ye-alloying ku-GH4706 superalloy, ethambekele ekubeni namabala amnyama nokuhlukaniswa kwamabala amhlophe.Izingxenye ezibalulekile zokuphela komshini oshisayo wezwe lami ophephela begesi abasindayo “yintamo ebhajwe”, okuvule indlela yenqubo yokulungiswa kwamadiski ophephela akhubazekile we-superalloy anezici zesiShayina anamalungelo azimele empahla yengqondo.
Ngemva kwe-anatomy, ukusebenza kwe-turbine disc kufinyelele izidingo zenkomba yezobuchwepheshe yama-alloys angaphandle afanayo, futhi umphumela oyingqopha-mlando ufinyelelwe.Lokhu kungenye intuthuko ebalulekile izwe lami eliye layenza emkhakheni wama-superalloy akhubazekile, okuqhubekisele phambili ubuchwepheshe bokulungiselela amadiski omoya amakhulu asekhaya ukuze afinyelele ezingeni elihamba phambili lamazwe ngamazwe.Ngomhla ziyisi-8 kuZibandlela, umhlangano oyingqopha-mlando wokubukeza i-node ye-GH4706 alloy full-size roulette forgings wabanjelwa e-Beijing.Ochwepheshe banikeze ukuhlolwa okuphezulu, okusho ukuthi isinyathelo esiqinile sithathiwe ekusetshenzisweni kwangempela kwediski yomshini wokushisa.
