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. kufa ngokukhohlisa kwilizwe lam ngoku—— I-GH4706 enkulu kakhulu ye-alloy turbine disk forgings, ilungele ukusetyenziswa phantsi kweemeko zobushushu obuphezulu I-650 degrees Celsius, kunye nenqanaba lamandla le-1200 MPa, ubunzima beetoni ze-13.5, kunye nobubanzi be-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. Ithekhnoloji yayo 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 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, ukwaphula umqobo wobugcisa bokulungiswa kwediski ye-superalloy turbine disk enkulu ekuhlangatyenwe nayo ngexesha lenkqubo yophuhliso, efana neteknoloji yokunyibilikisa okuphindwe kathathu kokwahlulo oluphantsi. kuba ingots ezinkulu zentsimbi kunye ingots enobunzima ngaphezu kweetoni 18, kwaye ngokuphindaphindiweyo upsetting kunye netheknoloji ehlumayo-ziinkozo eziqhakaza imivalo ezinkulu ububanzi 1000 mm, kunye nobubanzi 2200 Integral die forging kunye nobushushu obuphantsi ukwenza kunye nolawulo lombutho iteknoloji enkulu. iindawo zepleyiti ezinkulu kuneemilimitha. 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 ze-superalloy ezinkulu ezineempawu zamaTshayina ezinamalungelo azimeleyo epropathi yengqondo.
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 yobungakanani obupheleleyo be-roulette forging yabanjwa eBeijing. Iingcali zinike uvandlakanyo oluphezulu, nto leyo ethetha ukuba inyathelo eliluqilima lithathiwe ngokubhekiselele kusetyenziso lokwenene lwediski yomoya.
