Musi wa20 Zvita, mutori wenhau akadzidza kubva kuChina Iron and Steel Research Group Gaona Company kuti kambani yakatungamira mukugadzira pamwe chete Fushun Special Steel neErzhong Wanhang kekutanga mumazuva achangopfuura kuti vabudirire mukuyedza-kugadzira yakakura kwazvo superalloy turbine disk yakakosha. kufira munyika yangu pari zvino—— The super-hombe GH4706 alloy turbine disk forgings, inokodzera kushandiswa pasi pemamiriro ekushisa epamusoro e650 degrees celsius, ine simba re1200 MPa, huremu hwematani 13.5, uye dhayamita ye2380 mm, yakaputsa hurumende yekunze.
Sekureva kwaZhao Guangpu, mutungamiri wepurojekiti yekutsvagisa uye mutevedzeri wemukuru weSteel Research Gona Science neTekinoroji Komiti, inorema-basa gasi turbines ezviteshi zvemagetsi makuru ane mabhenefiti akadai sesimba repamusoro, kushanda kwakanyanya kwemafuta, vhoriyamu diki uye huremu, uye kusvibiswa kwakaderera.Iyo tekinoroji yekugadzira yave iyo yenyika tekinoroji level., Chimwe chezviratidzo zvakakosha zvesimba renyika rakazara.Nheyo dzayo dzinopisa-dzinopisa zvikamu ndeye disc imwe uye mbiri (turbine discs uye madhairekitori, mablades anoshanda), ayo anoita se "moyo" wevanhu.Ndidzo tekinoroji yakakosha yekugadzira gasi turbine uye bhodhoro rinorambidza kuwanikwa kweanorema gasi turbines.Heavy-duty gas turbine turbine disks inoda anopfuura 100,000 maawa enguva refu-yepamusoro-tembiricha uye yakanyanya-kushushikana sevhisi, uye inoda yakanyanya kukwirira metallurgical mhando yezvinhu, senge homogeneous, yakachena, yakanaka-grained, yakagadzikana zvinhu chimiro uye kuita;saizi yakakura, uye dhayamita yaro uye nzvimbo yekufungidzira zvakateerana Inosvika kupfuura 2.2 metres uye 4.2 square metres, inova neka 4 dhayamita yeaero injini turbine disk, ka10 nzvimbo yakarongedzerwa, uye 60 uremu, zvichingodaro. .Iyo yakakosha yekugadzira tekinoroji ye super-saizi superalloy turbine disks yanga yakavharika zvachose kunze kwenyika uye yakagarwa nenyika dzekuMadokero kwenguva yakareba.
Kuti izvi zviitike, Zhao Guangpu akatungamira timu yeprojekiti kuti iite tsvakiridzo yekutanga uye tsvagiridzo yetekinoroji, uye pakupedzisira vakagamuchira iyo yepamusoro-soro yepasi rose "kunyunguduka katatu + kudzokororwa kushungurudza + kaviri kugumbura + imwe-moto yakazara kufa forging" tekinoroji yekugadzirira kuita. International Standards, ichityora bhodhoro rehunyanzvi rehukuru-hukuru superalloy turbine disk gadziriro yakasangana panguva yekuvandudza, senge katatu-yakaderera-segregation tekinoroji yekunyungudutsa yeingots huru dzesimbi dzine ingots dzinorema kupfuura matani gumi nemasere, uye kudzokororwa kushungurudza uye zviyo zvakanaka. blooming michina kuti mbariro hombe ane dhayamita 1000 mm, pamwe dhayamita 2200 Integral kufa forging uye yakaderera-tembiricha kuumba uye sangano kudzora michina nokuda hombe ndiro zvikamu hombe kupfuura millimeters.Chikwata chepurojekiti chakaita tsvakiridzo yakazvimirira uye kusimudzira uye hunyanzvi hwekutanga hwekuremara kwemetallurgical senge yakanyanya kukwira Nb yemukati meiyo alloying element muGH4706 superalloy, inotarirwa kune matema matema uye chena nzvimbo kupatsanurwa.Zvinhu zvakakosha zvinopisa-zvinopisa zvema turbines egasi anorema emunyika yangu "yakanamira mutsipa", iyo yakavhura nzira yekugadzirira hukuru hwakaremara superalloy turbine disks ane hunhu hweChinese ane kodzero dzakazvimirira dzepfuma.
Mushure meanatomy, kuita kweiyo turbine disc kwasvika kune tekinoroji indekisi zvinodiwa zvealoys ekunze akafanana, uye chiitiko chakakosha chave kuwanikwa.Uku ndiko kumwe kusimukira kwakakosha kwakaitwa nenyika yangu mumunda weakaremara superalloys, izvo zvakafambisa tekinoroji yekugadzirira yemadhisiki makuru eturbine disks kuti asvike padanho rinotungamira repasi rose.Musi wa8 Zvita, musangano unokosha wekuongorora node yeGH4706 alloy yakazara-saizi roulette forging wakaitwa muBeijing.Nyanzvi dzakapa kuongororwa kwepamusoro, izvo zvinoreva kuti danho rakasimba rakatorwa kune chaiyo kushandiswa kweiyo turbine disk.
