Musi wa20 Zvita, mutori wenhau akanzwa kubva kuChina Iron and Steel Research Group Gaona Company kuti kambani iyi yakatungamira mukugadzira pamwe chete Fushun Special Steel neErzhong Wanhang kekutanga mumazuva achangopfuura kuti vaedze kubudirira kugadzira superalloy turbine disk integral die forging yakakura munyika yangu pari zvino—— Madhisiki eGH4706 alloy turbine disk forgings makuru kwazvo, akakodzera kushandiswa mumamiriro ekupisa akakwirira e650 degrees Celsius, ane simba re1200 MPa, huremu hwematani 13.5, uye dhayamita ye2380 mm, akaputsa monopoly yekunze.
Sekureva kwaZhao Guangpu, mutungamiriri wepurojekiti yekutsvagisa uye mutevedzeri wemutungamiriri weSteel Research Gona Science and Technology Committee, maturbine egasi anorema emagetsi makuru ane zvakanakira zvikuru zvakaita sesimba rakawanda, kushanda zvakanaka kwekupisa, vhoriyamu diki nehuremu hushoma, uye kusvibiswa kwakaderera. Tekinoroji yayo yekugadzira yave nhanho yetekinoroji yenyika. , Chimwe chezviratidzo zvakakosha zvesimba renyika. Zvikamu zvayo zvepakati zvinopisa idhisiki rimwe chete uye maviri (turbine discs nevatungamiriri, mashizha anoshanda), ayo anoshanda se "moyo" wevanhu. Ndiwo tekinoroji huru yekugadzira maturbine egasi uye dambudziko rinodzivisa nzvimbo yematurbine egasi anorema. Madhisiki eturbine egasi anorema anoda maawa anopfuura 100,000 ebasa refu rekupisa kwakanyanya uye rinorema, uye anoda mhando yepamusoro yezvinhu zvesimbi, zvakaita sechimiro chezvinhu zvakafanana, zvakachena, zvakapfava, zvakagadzikana uye kushanda; Yakakura, uye dhayamita yayo nenzvimbo yekuratidzwa kwayo zvakateerana. Inosvika anopfuura mamita 2.2 uye 4.2 square metres, inova dhayamita yakapetwa ka4 yedhisiki re turbine re aero engine, kagumi pane nzvimbo yakafungidzirwa, uye ka60 pane huremu, zvichingodaro. Tekinoroji huru yekugadzira madhisiki e superalloy turbine akakura yave ichivharirwa kunze kwenyika uye yave ichitongwa nenyika dzekuMadokero kwenguva yakareba.
Kuti izvi zviitike, Zhao Guangpu akatungamira chikwata cheprojekiti iyi kuita tsvakurudzo yekutanga uye tsvakiridzo yetekinoroji, uye pakupedzisira akashandisa tekinoroji yepamusoro-soro yepasi rose ye "triple smelting + repeated upsetting + twice upsetting + one-fire overall die forging" kuti ashandise maStandards epasi rose, achipfuura nemuganho wehunyanzvi hwekugadzirira dhisiki re superalloy turbine guru rakasangana naro panguva yekugadzira, senge tekinoroji yekunyungudutsa triple low-segregation yeingots hombe dzesimbi dzine ingots dzinorema anopfuura matani gumi nemasere, uye tekinoroji yekunyungudutsa triple uye fine-grain blooming yemabhawa makuru ane dhayamita ye1000 mm, ane dhayamita ye2200 Integral die forging uye tekinoroji yekuumba nekutonga kwepasi-tembiricha yezvikamu zvikuru zveplate zvakakura kupfuura mamirimita. Chikwata cheprojekiti iyi chakaita tsvakiridzo yakazvimirira nekugadzira uye hunyanzvi hwepakutanga hwezvikanganiso zvesimbi zvakaita sehuwandu hwakawanda hweNb hwechinhu chekusanganisa muGH4706 superalloy, iyo inowanzo kuve nemavanga matema uye kupatsanurwa kwemavanga machena. Zvinhu zvikuru zvinopisa zvematurbine egasi anorema munyika yangu "zvine mutsipa wakaoma", izvo zvakavhura nzira yekugadzira madhisiki makuru e superalloy turbine ane hunhu hwekuChina ane kodzero dzepfungwa dzakazvimirira.
Mushure mekugadzirwa kwemajini, mashandiro edhisiki re turbine asvika pazvinodiwa zvehunyanzvi hwemhando ye alloys dzekunze dzakafanana, uye mhedzisiro yakakosha yakawanikwa. Uku ndiko kumwe kubudirira kwakakosha kwakaitwa nenyika yangu mumunda wema superalloys akakanganisika, izvo zvakatungamira tekinoroji yekugadzirira madhisiki e turbine makuru emuno kusvika padanho rekutungamira repasi rose. Musi wa8 Zvita, musangano wekuongorora milestone node weGH4706 alloy full-size roulette forgings wakaitwa muBeijing. Nyanzvi dzakapa ongororo yepamusoro, zvinoreva kuti danho rakasimba ratorwa pakushandiswa chaiko kwedhisiki re turbine.
