Ferromanganese Alloy Qhia Casting Superalloy Method Related Cov Ntaub Ntawv Koj Puas Paub?
Nws yog cov khoom siv superalloy uas ncaj qha fabricated los ntawm casting. Casting superalloy yog ib hom superalloy uas yog refined los ntawm alloy raw cov ntaub ntawv thiab ces nrum los ntawm lub tshuab nqus tsev remelting. Piv nrog superalloy, daim ntawv thov kub thiab lub zog yog siab dua, qib ntawm alloying yog siab dua, qhov ntau npaum li cas tsawg dua thiab zoo, feem ntau yog siv rau kev npaj cov khoom zoo. Casting superalloy tseem tuaj yeem muab faib ua equiaxed siv lead ua casting kub kub. Qhov kev ua tau zoo thiab kev npaj nyuaj ntawm kev taw qhia ua kom muaj zog cylindrical superalloy thiab ib leeg siv lead ua superalloy tau txhim kho txuas ntxiv.
Equiaxed crystal casting superalloy yog hais txog cov superalloy uas yog npaj los ntawm cov txheej txheem peev casting. Cov qauv nplej yog equiaxed thiab cov nqi tsim khoom tsawg. Nws muaj cov cuab yeej zoo heev ntawm qhov kub thiab nruab nrab thiab siv dav hauv aerospace. Hauv aerospace thiab lwm yam kev lag luam, nws tuaj yeem siv rau hauv kev tsim cov txheej txheem loj loj xws li aeroengine diffuser thiab chassis ntawm -235 ~ 1050 degree . Integral casting turbines. Cov kws qhia. Kev taw qhia, turbine hniav, qhov chaw foob pob hluav taws cav turbopump thiab lwm yam muaj feem xyuam nrog, cov qauv tsim. Dimensional raug thiab nyias-phab ntsa lub teeb yuag yog cov tsim qauv.
K418 alloy yog ib hom cam khwb cia superalloy nrog ntau npaum li cas. Ferromanganese alloy tau dav siv nyob rau hauv aviation ntau lawm. Hauv av thiab offshore gas turbine turbine ua haujlwm hniav. Qhia cov hniav thiab ib qho cam khwb cia turbines, ib qho cam khwb cia turbine rotors thiab cov lus qhia rau aerospace elastic engine, turbocharge turbines rau diesel xyaw thiab roj av cav. K deformation superalloy 4169 tsim los ntawm alloy GH4169, suav nrog. Qhov zoo tshaj plaws ntawm cov ntsiab lus hlau yog siab zog nyob rau hauv ntau qhov kub thiab txias (-253 ~ 650 degree ). Plasticity. Zoo heev corrosion kuj. Radiation kuj thiab zoo vuam kev ua tau zoo.
Directionally solidified superalloy yog columnar siv lead ua superalloy uas yog sib npaug rau lub hauv paus kev ntxhov siab axis los ntawm cov txheej txheem kev taw qhia kom tshem tawm cov teeb meem kab rov tav kab (DS lossis DZ alloys).
Tom qab pom muaj teeb meem hauv cov txheej txheem siv, cov txheej txheem ntawm cov hlau tsim tau raug kho. Tom qab cov hniav nyias nyias tau raug rau qhov kub kub tawg hauv cov txheej txheem casting, ferromanganese alloy chaw tsim tshuaj paus tau hais tias lub zog alloy yuav tsum tau ua tiav raws li txoj cai alloying thiab solidification txoj kev xav. Castability. Stability ntawm cov ntaub so ntswg. Lub redeveloped alloy muaj corrosion kuj thiab lwm yam.
