Thaum Lub Kaum Ob Hlis 20th, tus neeg sau xov xwm tau kawm los ntawm Tuam Tshoj Iron thiab Steel Research Group Gaona Tuam Txhab tias lub tuam txhab tau ua tus thawj coj hauv kev sib koom ua lag luam Fushun Tshwj Xeeb Steel thiab Erzhong Wanhang thawj zaug hauv cov hnub tsis ntev los no kom ua tiav kev sim-ua qhov loj tshaj plaws superalloy turbine disk ib txwm muaj. tuag forging nyob rau hauv kuv lub teb chaws tam sim no - Lub super-loj GH4706 alloy turbine disk forgings, haum rau siv nyob rau hauv kub kub tej yam kev mob ntawm 650 degrees Celsius, nrog ib tug muaj zog theem ntawm 1200 MPa, ib tug luj ntawm 13.5 tons, thiab ib txoj kab uas hla ntawm 2380 mm, tsoo lub teb chaws monopoly.
Raws li Zhao Guangpu, tus thawj coj ntawm txoj haujlwm tshawb fawb thiab lwm tus thawj coj ntawm Steel Research Gona Science thiab Technology Committee, hnyav roj turbines rau cov chaw nres tsheb fais fab loj muaj cov txiaj ntsig zoo xws li lub zog siab, siab thermal efficiency, me me ntim thiab qhov hnyav, thiab muaj kuab paug tsawg.Nws cov thev naus laus zis tsim tau dhau los ua lub teb chaws thev naus laus zis., Ib qho ntawm cov cim tseem ceeb ntawm lub teb chaws muaj zog.Nws cov tseem ceeb kub-kawg Cheebtsam yog ib tug disc thiab ob (turbine discs thiab qhia, ua hauj lwm hniav), uas ua raws li lub "lub siab" ntawm tib neeg beings.Lawv yog cov thev naus laus zis tseem ceeb rau kev tsim cov roj turbine thiab lub bottleneck txwv qhov chaw ntawm cov roj turbines hnyav.Heavy-duty gas turbine turbine disks xav tau ntau tshaj 100,000 xuab moos ntawm kev ua haujlwm kub thiab kev ntxhov siab, thiab xav tau cov khoom siv hlau zoo heev, xws li homogeneous, ntshiab, nplua-grained, ruaj khov cov qauv thiab kev ua haujlwm;loj loj, thiab nws txoj kab uas hla thiab projection cheeb tsam yog feem ntau Nws ncav cuag ntau tshaj 2.2 meters thiab 4.2 square meters, uas yog 4 npaug ntawm lub cheeb ntawm lub aero engine turbine disk, 10 npaug ntawm qhov projected cheeb tsam, thiab 60 npaug ntawm qhov hnyav, thiab hais txog. .Cov txheej txheem tsim khoom tseem ceeb ntawm super-loj superalloy turbine disks tau nyob rau hauv qhov kev txwv tsis pub nyob txawv teb chaws thiab tau raug monopolized los ntawm Western lub teb chaws tau ntev.
Txog rau qhov kawg no, Zhao Guangpu tau coj cov pab pawg ua haujlwm los ua cov kev tshawb fawb thiab kev tshawb fawb thev naus laus zis, thiab thaum kawg tau txais kev tshaj lij thoob ntiaj teb "triple smelting + rov qab ntxhov siab + ob zaug chim siab + ib-hluav taws tag nrho tuag forging" npaj thev naus laus zis los siv. Cov txheej txheem thoob ntiaj teb, tawg los ntawm cov txheej txheem kev ua haujlwm ntawm qhov loj-loj superalloy turbine disk npaj tau ntsib thaum lub sijhawm txhim kho, xws li triple low-segregation smelting thev naus laus zis rau cov hlau loj loj nrog cov ingots hnyav dua 18 tons, thiab rov qab ntxhov siab thiab nplua-grain. Blooming tshuab rau cov tuav loj nrog ib txoj kab uas hla ntawm 1000 hli, nrog ib txoj kab uas hla ntawm 2200 Integral tuag forging thiab qis-temperature forming thiab lub koom haum tswj technology rau loj phaj qhov chaw loj tshaj millimeters.Pab pawg ua haujlwm tau ua tiav kev tshawb fawb ywj pheej thiab kev tsim kho tshiab thiab kev tsim kho tshiab rau metallurgical tsis xws luag xws li cov ntsiab lus Nb siab heev ntawm cov khoom siv alloying hauv GH4706 superalloy, uas yog feem ntau rau cov pob dub thiab dawb qhov chaw sib cais.Qhov tseem ceeb kub-kawg Cheebtsam ntawm kuv lub teb chaws cov roj turbines hnyav yog "cuck caj dab", uas tau qhib txoj hauv kev rau kev npaj cov deformed superalloy turbine disks loj nrog Suav cov yam ntxwv nrog kev ywj pheej ntawm kev txawj ntse muaj cai.
Tom qab lub cev nqaij daim tawv, qhov kev ua tau zoo ntawm lub turbine disc tau mus txog qhov kev ntsuas qhov xav tau ntawm cov hlau txawv teb chaws zoo sib xws, thiab cov txiaj ntsig tseem ceeb tau ua tiav.Qhov no yog lwm qhov tseem ceeb tshaj plaws uas kuv lub teb chaws tau ua nyob rau hauv lub tshav pob ntawm deformed superalloys, uas tau tsav kev npaj technology ntawm domestic super-loj turbine disks mus txog rau lub thoob ntiaj teb ua theem.Thaum Lub Kaum Ob Hlis 8th, lub rooj sib tham tseem ceeb ntawm lub rooj sib tham rau GH4706 alloy tag nrho-loj roulette forgings tau tuav hauv Beijing.Cov kws tshaj lij tau muab qhov kev ntsuam xyuas siab, uas txhais tau hais tias cov kauj ruam tseem ceeb tau raug coj mus rau kev siv tiag tiag ntawm cov turbine disk.
