Ib leeg siv lead ua turbine hniav casting txheej txheem yog ib qho kev tsim technology siab heev siv los tsim cov turbine hniav zoo rau cov roj turbine xyaw, tshwj xeeb tshaj yog nyob rau hauv aerospace daim ntaub ntawv. Piv nrog cov tsoos polycrystalline hniav, ib leeg-crystal hniav muaj superior txhua yam khoom thiab kub tsis kam.
Hauv qab no yog ib qho kev piav qhia ntawm ib leeg siv lead ua turbine hniav casting txheej txheem:
Kev xaiv noob:
Cov txheej txheem pib nrog kev xaiv ntawm cov noob siv lead ua, uas yog thawj qhov chaw nucleation rau kev loj hlob siv lead ua. Cov noob siv lead ua feem ntau yog tsim los ntawm cov khoom siv nrog cov qauv siv lead ua zoo sib xws rau cov khoom siv turbine hniav uas xav tau, xws li nickel-based superalloy.
Kev nqis peev casting pwm npaj:
Precision ceramic pwm, tseem hu ua peev pwm, yog tsim los siv txoj kev poob wax casting. Cov pwm yog tsim los ua kom haum raws li qhov yuav tsum tau ua thiab cov yam ntxwv ntawm cov turbine hniav nrog rau ib qho kev loj hlob siv lead ua. Them tshwj xeeb rau kev taw qhia ntawm cov noob hauv pwm.
Pwm Assembly:
Ua tib zoo tso cov noob siv lead ua rau hauv pwm thiab teeb tsa txhua qhov tsim nyog rooj vag thiab kev pub noj kom yooj yim rau kev khiav ntawm cov hlau molten thaum lub sij hawm casting txheej txheem.
Melting thiab casting:
High-zoo nickel-based superalloys haum rau ib qho kev loj hlob siv lead ua yog yaj hauv lub tshuab nqus tsev induction rauv lossis cov cuab yeej zoo sib xws. Tom qab ntawd cov hlau molten yog nchuav rau hauv cov pwm npaj raws li kev tswj xyuas, kom ntseeg tau tias txawm tias txhaws thiab khov.
Directional Solidification:
Raws li molten hlau solidifies, cov noob siv lead ua ua rau cov qauv siv lead ua ib leeg loj hlob hauv qhov kev taw qhia ua ntej. Cov txheej txheem no, hu ua directional solidification, xyuas kom meej tias cov turbine blades yog tsim los ntawm ib tug crystals tsis muaj grain ciam teb, yog li pab txhawb lawv txhua yam khoom thiab high-temperature kuj.
Cooling thiab solidification:
Tom qab casting, cov pwm yog maj mam txias los tiv thaiv thermal kev nyuaj siab thiab xyuas kom meej qhov kev ncaj ncees ntawm ib tug siv lead ua qauv. Thaum cov hlau tau ua tiav tiav, cov pwm ceramic raug tshem tawm, tawm hauv qab ntawm cov khoom siv ib leeg-crystal turbine hniav.
Cov kev kho mob tom qab casting:
Cam khwb cia turbine hniav tuaj yeem dhau los ua ntau yam kev kho tom qab casting xws li kev kho cua sov, qhov chaw tiav thiab kev tshuaj xyuas qhov ntev kom tau txais cov khoom siv kho qhov muag, qhov zoo thiab qhov raug.
Kev Tswj Xyuas Zoo:
Thoob plaws hauv cov txheej txheem casting, kev tswj xyuas nruj nruj yog siv los saib xyuas qhov tsis xws li kub, siab thiab siv lead ua kev taw qhia. Cov txheej txheem kuaj tsis muaj kev puas tsuaj kuj tuaj yeem siv los txheeb xyuas qhov tseeb ntawm cov qauv siv lead ua ib leeg thiab kuaj xyuas qhov tsis zoo lossis qhov tsis zoo.
