Ngomhla wama-20 kaDisemba, intatheli yafunda kwiChina Iron kunye neNkampani yoPhando lweNsimbi yeGaona ukuba inkampani yakhokela ngokudibeneyo ekuveliseni iFushun Special Steel kunye ne-Erzhong Wanhang okokuqala ngqa kwezi ntsuku zidlulileyo ukuvelisa ngempumelelo eyona diski ye-superalloy turbine disk edityanisiweyo. die forging kwilizwe lam ngoku—— I-GH4706 i-alloy turbine disk forgings enkulu-enkulu kakhulu, ifanele ukusetyenziswa phantsi kweemeko zobushushu obuphezulu obungama-650 degrees celcius, kunye nomgangatho wamandla 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 yeesimboli ezibalulekileyo zamandla esizwe abanzi.Amacandelo ayo angundoqo okuphela kwe-hot-end idiski 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 ngaphezulu kweeyure ze-100,000 zexesha elide lobushushu obuphezulu kunye nenkonzo yoxinzelelo oluphezulu, kwaye zifuna umgangatho ophezulu kakhulu we-metallurgical wezinto, 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-superalloy turbine disks ivaliwe ngokupheleleyo 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 yolungiselelo lwediski yeinjini ye-superalloy enkulu ekuhlangatyenwe nayo ngexesha lenkqubo yophuhliso, njengobuchwephesha bokunyibilikisa obuthathu obunocahlulo olusezantsi kwiingots ezinkulu zentsimbi ezineengots ezinobunzima obungaphezulu kweetoni ezili-18, kunye nokuphazamiseka okuphindaphindiweyo kunye neenkozo ezicolekileyo. ukuqhakaza iteknoloji imivalo ezinkulu kunye ububanzi 1000 mm, kunye ububanzi 2200 Integral kufa forging kunye nobushushu obuphantsi ukwenza kunye nombutho iteknoloji yokulawula iinxalenye ipleyiti ezinkulu ezinkulu kune millimeters.Iqela leprojekthi lenze uphando oluzimeleyo kunye nophuhliso kunye nokuveliswa kwezinto ezintsha kwi-metallurgical defects 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 zamaTshayina ezinamalungelo azimeleyo epropathi yomenzi.
Emva kwe-anatomy, ukusebenza kwediski ye-injini yomoya kufikelele kwiimfuno zesalathiso sobugcisa bezinto ezifanayo zangaphandle, kwaye isiphumo esibalulekileyo siphunyeziwe.Le yenye impumelelo ebalulekileyo ilizwe lam elenze 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 lithathiwe ekusetyenzisweni kokwenyani kwediski yomoya.
