Ngomhlaka-20 Disemba, intatheli yezwa kwi-China Iron and Steel Research Group Gaona Company ukuthi inkampani ihole ekukhiqizeni ngokubambisana i-Fushun Special Steel kanye ne-Erzhong Wanhang okokuqala ezinsukwini zamuva ukuze ivivinye ngempumelelo ukukhiqiza i-superalloy turbine disk integral die forging enkulu kunazo zonke ezweni lakithi njengamanje—— Ama-super-large GH4706 alloy turbine disk forgings, afanele ukusetshenziswa ngaphansi kwezimo zokushisa eziphakeme ezingama-650 degrees Celsius, anezinga lamandla angu-1200 MPa, isisindo samathani angu-13.5, kanye nobubanzi obungu-2380 mm, aphule ubukhosi bangaphandle.
Ngokusho kukaZhao Guangpu, umholi wephrojekthi yocwaningo kanye nephini lomqondisi weKomidi Lesayensi Nobuchwepheshe Locwaningo Lwensimbi i-Gona, ama-turbine egesi anzima eziteshini ezinkulu zamandla anezinzuzo ezivelele njengamandla aphezulu, ukusebenza kahle kokushisa okuphezulu, umthamo omncane nesisindo, kanye nokungcola okuphansi. Ubuchwepheshe bayo bokukhiqiza sebube yizinga lobuchwepheshe likazwelonke. , Enye yezimpawu ezibalulekile zamandla kazwelonke aphelele. Izingxenye zayo eziyinhloko ze-hot-end yidiski eyodwa kanye nezimbili (ama-disc e-turbine kanye neziqondiso, ama-blade asebenzayo), asebenza njenge "inhliziyo" yabantu. Angubuchwepheshe obuyisihluthulelo bokukhiqiza ama-turbine egesi kanye ne-bottleneck evimbela indawo yama-turbine egesi anzima. Ama-diski e-turbine e-turbine egesi anzima adinga amahora angaphezu kuka-100,000 ensizakalo yesikhathi eside yokushisa okuphezulu kanye nokucindezeleka okuphezulu, futhi adinga ikhwalithi ephezulu kakhulu yezinto zokwakha, njengesakhiwo sezinto ezilinganayo, ezimsulwa, ezicolekile, ezizinzile kanye nokusebenza; Ubukhulu bayo obukhulu, kanye nobubanzi bayo kanye nendawo yokubuka ngokulandelana. Ifinyelela ngaphezu kwamamitha-skwele angu-2.2 kanye namamitha-skwele angu-4.2, okuphindwe kane ububanzi bediski ye-turbine yenjini ye-aero, izikhathi eziyi-10 zendawo ebonisiwe, kanye nesisindo esiphindwe ka-60, njalo njalo. Ubuchwepheshe bokukhiqiza obuyinhloko bamadiski e-turbine amakhulu kakhulu bebulokhu buvinjelwe ngokuphelele kwamanye amazwe futhi buphethwe amazwe aseNtshonalanga isikhathi eside.
Ngenxa yalokhu, uZhao Guangpu wahola ithimba lephrojekthi ukwenza uchungechunge locwaningo oluyisisekelo kanye nocwaningo lwezobuchwepheshe, futhi ekugcineni wamukela ubuchwepheshe bokulungiselela i-"triple smelting + repeated upcoming + twice upcoming + one-fire overall die forging" obuthuthuke kakhulu emhlabeni wonke ukuze kusetshenziswe amazinga omhlaba wonke, ephula imingcele yobuchwepheshe yokulungiswa kwediski ye-superalloy turbine enkulu ehlangane nayo ngesikhathi senqubo yokuthuthukiswa, njengobuchwepheshe bokuncibilikisa obuncane obuthathu bezinsimbi ezinkulu zensimbi ezinezinsimbi ezinesisindo esingaphezu kwamathani ayi-18, kanye nobuchwepheshe bokuqhakaza obuphindaphindwayo kanye nobokuhluma okusanhlamvu okuhle kwezinsimbi ezinkulu ezinobubanzi obungu-1000 mm, ezinobubanzi obungu-2200 bokuncibilikisa okuhlanganisiwe kanye nobuchwepheshe bokulawula ukwakheka nokuhlelwa kwezingxenye ezinkulu zepuleti ezinkulu ezingaphezu kwamamilimitha. Ithimba lephrojekthi lenze ucwaningo oluzimele kanye nentuthuko kanye nokusungula izinto ezintsha kwasekuqaleni kwamaphutha ensimbi njengokuqukethwe okuphezulu kakhulu kwe-Nb kwento yokuhlanganisa ku-GH4706 superalloy, evame ukuba namabala amnyama kanye nokuhlukaniswa kwamabala amhlophe. Izingxenye ezibalulekile ezishisayo zama-turbine anamandla egesi ezweni lami “ziyintamo enamathele”, okuvule indlela yenqubo yokulungiselela amadiski amakhulu e-turbine akhubazekile anezimpawu zaseShayina ezinamalungelo obunikazi azimele.
Ngemva kokwakheka komzimba, ukusebenza kwediski ye-turbine kufinyelele ezidingweni zenkomba yobuchwepheshe be-alloys efanayo yangaphandle, futhi kufezwe umphumela obalulekile. Lena enye intuthuko ebalulekile izwe lami eliyenzile emkhakheni wama-superalloy aguqukile, okuqhube ubuchwepheshe bokulungiselela amadiski e-turbine amakhulu asekhaya ukuze afinyelele ezingeni eliholayo lamazwe ngamazwe. Ngomhlaka-8 Disemba, umhlangano wokubuyekezwa kwe-milestone node we-GH4706 alloy full-size roulette forgings wabanjwa eBeijing. Ochwepheshe banikeze ukuhlolwa okuphezulu, okusho ukuthi kuthathwe isinyathelo esiqinile ekusetshenzisweni kwangempela kwediski ye-turbine.
