Ngomhla wama-20 kweyoMnga, intatheli yeva kwiChina Iron and Steel Research Group Gaona Company ukuba inkampani ikhokela ekuveliseni iFushun Special Steel kunye ne-Erzhong Wanhang okokuqala ngqa kwiintsuku zamva nje ukuze iphumelele ekuveliseni eyona superalloy turbine disk integral die forging inkulu kwilizwe lam okwangoku—— Ii-super-large GH4706 alloy turbine disk forgings, ezifanelekileyo ukusetyenziswa phantsi kweemeko zobushushu obuphezulu be-650 degrees Celsius, ezinamandla e-1200 MPa, ubunzima beetoni ezili-13.5, kunye nobubanzi be-2380 mm, zaphula ulawulo lwangaphandle.
Ngokutsho kukaZhao Guangpu, inkokeli yeprojekthi yophando kunye nosekela-mlawuli weKomiti yeSayensi neTekhnoloji yoPhando lweNsimbi iGona, iiturbine zegesi ezinzima zezikhululo zamandla ezinkulu zinezibonelelo ezibalaseleyo ezifana namandla aphezulu, ukusebenza kakuhle kobushushu, umthamo omncinci kunye nobunzima, kunye nongcoliseko oluphantsi. Itekhnoloji yayo yokuvelisa iye yaba linqanaba letekhnoloji yesizwe. , Enye yeempawu ezibalulekileyo zamandla esizwe apheleleyo. Izinto zayo eziphambili ezishushu yidiski enye kunye nezimbini (iidiski zeturbine kunye nezikhokelo, iiblade ezisebenzayo), ezisebenza njenge "ntliziyo" yabantu. Ziyitekhnoloji ephambili yokwenziwa kweeturbine zegesi kunye nomqobo othintela indawo yeeturbine zegesi ezinzima. Iidiski zeturbine zegesi ezinzima zifuna iiyure ezingaphezu kwe-100,000 zenkonzo yexesha elide yobushushu obuphezulu kunye noxinzelelo oluphezulu, kwaye zifuna umgangatho ophezulu kakhulu wezinto zesinyithi, ezifana nolwakhiwo lwezinto ezifanayo, ezicocekileyo, ezicolekileyo, ezizinzileyo kunye nokusebenza; ubukhulu bayo obukhulu, kwaye ububanzi bayo kunye nendawo yokubonisa ngokulandelelanayo. Ifikelela ngaphezu kweemitha ezingama-2.2 kunye neemitha zesikwere ezingama-4.2, eziphindwe kane ubukhulu bediski ye-turbine ye-aero injini, izihlandlo ezili-10 indawo ebonisiweyo, kunye neziphindwe ka-60 ubunzima, njalo njalo. Itekhnoloji ephambili yokuvelisa iidiski ze-superalloy turbine ezinkulu ibisoloko ivaliwe kwamanye amazwe kwaye ibilawulwa ngamazwe aseNtshona ixesha elide.
Ngenxa yoku, uZhao Guangpu ukhokele iqela leprojekthi ukuba lenze uthotho lophando olusisiseko kunye nophando lwetekhnoloji, kwaye ekugqibeleni wamkela itekhnoloji yokulungiselela i-"triple smelting + repeated upsetting + twice upsetting + one-fire overall die forging" yehlabathi jikelele ephucukileyo ukuze kuphunyezwe iMigangatho yamazwe ngamazwe, ephula imiqobo yobugcisa yokulungiswa kwediski ye-superalloy turbine enkulu efunyenwe ngexesha lenkqubo yophuhliso, njengetekhnoloji yokunyibilikisa i-triple low-segregation kwi-ingots ezinkulu zentsimbi ezine-ingots ezinobunzima obungaphezulu kweetoni ezili-18, kunye netekhnoloji yokuqhakaza ephindaphindayo kunye ne-fine-grain kwi-bar ezinkulu ezinobubanzi be-1000 mm, enobubanzi be-2200 Integral die forging kunye netekhnoloji yokulawula ulwakhiwo oluphantsi kwiindawo ezinkulu zeplate ezinkulu ezinkulu kuneemilimitha. Iqela leprojekthi lenze uphando oluzimeleyo kunye nophuhliso kunye nophuhliso kunye noyilo lwantlandlolo kwiziphene ze-metallurgical ezifana nomxholo ophezulu kakhulu we-Nb we-alloying element kwi-superalloy ye-GH4706, ethanda ukuba namabala amnyama kunye nokwahlulwa kwamabala amhlophe. Izinto eziphambili ezishushu kwiiturbine zegesi ezinzima zelizwe lam "ziintamo ezinamatheleyo", nto leyo evule indlela yenkqubo yokulungiselela iidiski ezinkulu zeturbine eziguquliweyo ezineempawu zaseTshayina ezinamalungelo epropathi yengqondo azimeleyo.
Emva kokwakheka komzimba, ukusebenza kwediski yeturbine kufikelele kwiimfuno zesalathisi sobuchwephesha zeealloys ezifanayo zangaphandle, kwaye isiphumo esibalulekileyo sifezekisiwe. Olu lolunye uphuculo olubalulekileyo olwenziwe lilizwe lam kwicandelo lee-superalloys eziguqulweyo, oluye lwaqhuba itekhnoloji yokulungiselela iidiski zeturbine ezinkulu zasekhaya ukufikelela kwinqanaba eliphambili lamazwe ngamazwe. Ngomhla we-8 kuDisemba, intlanganiso yophononongo lwe-milestone node ye-GH4706 alloy full-size roulette forgings yabanjwa eBeijing. Iingcali zinike uvavanyo oluphezulu, oko kuthetha ukuba inyathelo eliqinileyo lithathiwe ekusetyenzisweni kwediski yeturbine ngokwenene.
