Nge-20 kaDisemba, intatheli yafunda kwi-China Iron kunye neQela loPhando lweNsimbi yeGaona ukuba inkampani ikhokele ngokudibeneyo ekuveliseni iFushun Special Steel kunye ne-Erzhong Wanhang okokuqala ngqa kwezi ntsuku zidlulileyo ukuvelisa ngempumelelo eyona diski ye-injini ye-superalloy enkulu. die forging kwilizwe lam ngoku—— I-GH4706 i-alloy turbine disk forgings enkulu kakhulu, ifanele ukusetyenziswa phantsi kweemeko zobushushu obuphezulu obungama-650 degrees celcius, nomgangatho wokomelela we-1200 MPa, ubunzima be-13.5 yeetoni, kunye nobubanzi obuyi-2380 mm, yaphula i-monopoly yangaphandle.
Ngokutsho kukaZhao Guangpu, inkokeli yeprojekthi yophando kunye nosekela-mlawuli we-Steel Research Gona Science and Technology Committee, ii-turbines zegesi ezinzima kwizikhululo zamandla amakhulu zineenzuzo ezibalaseleyo ezifana namandla aphezulu, ukusebenza kakuhle kwe-thermal, umthamo omncinci kunye nobunzima, kunye nongcoliseko oluphantsi.Iteknoloji yokuvelisa iye yaba yinqanaba leteknoloji yelizwe., Enye yeempawu ezibalulekileyo zamandla esizwe abanzi.Amacandelo alo angundoqo atshisa i-disc enye kunye neembini (iidiski ze-turbine kunye nezikhokelo, ii-blades zokusebenza), ezisebenza "njengentliziyo" yabantu.Zibuchwephesha obuphambili bokwenziwa kweeinjini zegesi kunye nomqobo othintela ukwenziwa kwasekhaya kweeinjini zegesi ezinzima.Iidiski ze-injini ye-injini yegesi enzima zifuna ngaphezu kweeyure ze-100,000 zexesha elide lobushushu obuphezulu kunye nenkonzo yoxinzelelo oluphezulu, kwaye zifuna umgangatho ophezulu kakhulu we-metallurgical wezinto eziphathekayo, ezifana ne-homogeneous, pure, i-fine-grained, isakhiwo sezinto eziphathekayo kunye nokusebenza;ubukhulu, kunye nobukhulu bayo kunye nommandla woqikelelo ngokulandelelana Ifikelela ngaphezu kwe-2.2 yeemitha kunye ne-4.2 yeemitha zesikwere, eziphindwe ka-4 ububanzi bediski ye-injini ye-aero, amaxesha angama-10 kwindawo eqikelelweyo, kunye namaxesha angama-60 ubunzima, njalo njalo. .Itekhnoloji yemveliso engundoqo yeediski ze turbine ye-super-sized superalloy ibivaliwe kumazwe angaphandle kwaye ilawulwa ngamazwe aseNtshona ixesha elide.
Ukuza kuthi ga ngoku, uZhao Guangpu ukhokele iqela leprojekthi ukuba lenze uluhlu lophando olusisiseko kunye nophando lwetekhnoloji, kwaye ekugqibeleni wamkela eyona ndawo iphambili yehlabathi "ukunyibilikisa kathathu + ukuphinda kuphazamiseke + kabini ukucaphukisa + umlilo omnye jikelele wokufa" itekhnoloji yokulungiselela ukuphumeza. ImiGangatho yezizwe ngezizwe, ukophula ibhotile yobugcisa yokulungiswa kwediski ye-injini ye-superalloy enkulu ekuhlangabezene nayo ngexesha lenkqubo yophuhliso, njengobuchwephesha bokunyibilikisa obuthathu obunocahlulo olusezantsi kwiingots ezinkulu zentsimbi ezineengots ezinobunzima obungaphezulu kweetoni ezili-18, kunye nokuphazamiseka okuphindaphindiweyo kunye neenkozo ezicolekileyo. iteknoloji eqhakaza imivalo ezinkulu kunye ububanzi 1000 mm, kunye ububanzi 2200 Integral kufa forging kunye nobushushu obuphantsi ukwenza kunye nombutho ulawulo ubuchwepheshe iinxalenye ipleyiti ezinkulu ezinkulu kune millimeters.Iqela leprojekthi lenze uphando oluzimeleyo kunye nophuhliso kunye nokuqaliswa kwezinto ezintsha kwiziphene ze-metallurgical ezifana nomxholo we-Nb ophezulu kakhulu we-alloying element kwi-GH4706 superalloy, ethandwa kakhulu kumabala amnyama kunye nokwahlulwa kwamabala amhlophe.Amacandelo angundoqo okuphela kobushushu othungelwano lwerhasi enzima yelizwe lam “yintamo exingileyo”, eye yavula indlela yenkqubo yokulungisa iidiski ze turbine ye-superalloy ezinkulu ezinokukhubazeka ezineempawu zaseTshayina ezinamalungelo azimeleyo epropathi yomenzi.
Emva kwe-anatomy, ukusebenza kwediski ye-injini ye-injini ifikelele kwiimfuno zesalathiso sobugcisa be-alloys zangaphandle ezifanayo, kunye nesiphumo esibalulekileyo siphunyeziwe.Le yenye impumelelo ebalulekileyo ilizwe lam elenzileyo kwinkalo yee-superalloys ezigogekileyo, eziqhube ubuchwephesha bokulungiselela iidiski zeinjini zomoya ezinkulu zasekhaya ukufikelela kwinqanaba eliphambili lamazwe ngamazwe.Ngomhla we-8 kaDisemba, intlanganiso yophononongo olubalulekileyo lwe-GH4706 ye-alloy egcwele ubungakanani be-roulette forging yabanjwa eBeijing.Iingcali zinike uvandlakanyo oluphezulu, nto leyo ethetha ukuba inyathelo eliqinileyo lithathiweyo ngokubhekiselele kusetyenziso lokwenene lwediski yomoya.
