A. Tsim Tus Qauv
Nws siv cov qauv nrog tib cov ntsiab lus raws li qhov ua tiav, tshwj tsis yog tias muaj kev tso cai rau thermal contraction (xws li shrinking).
Cov qauv feem ntau yog ua los ntawm wax siv cov hlau txhaj tshuaj tuag.
B. Mounting Tus Qauv Ciab Thiab Tsim Tsob Ntoo
Thaum tsim cov qauv siv quav ciab, nws tau sib sau ua ke nrog lwm cov khoom siv quav ciab los tsim lub rooj vag thiab khiav hlau xa khoom.
Nyob ntawm qhov loj thiab teeb tsa ntawm qhov xav tau ua tiav, ntau cov qauv siv quav ciab tuaj yeem ua tiav siv ib tsob ntoo.
C. Tsim Lub Plhaub Pwm
Tag nrho cov qauv siv quav ciab yog dipped nyob rau hauv ceramic slurry, them nrog xuab zeb stucco, thiab tso cai kom qhuav.
Cov voj voog ntawm cov dej ntub dej thiab cov stuccoing tom ntej yog rov ua dua kom txog thaum lub plhaub ntawm qhov xav tau tuab yog tsim. Lub thickness ntawd yog ib feem dictated los ntawm cov khoom loj thiab configuration.
Thaum lub plhaub ceramic tau qhuav lawm, nws yuav muaj zog txaus kom khaws cov hlau molten thaum lub sij hawm casting.
D. Siv quav ciab tshem tawm
Tag nrho cov sib dhos yog muab tso rau hauv ib lub tshuab autoclave kom yaj tawm feem ntau ntawm cov quav ciab.
Ib qho wax uas tseem tshuav rau hauv lub plhaub ceramic yog hlawv tawm hauv qhov cub. Nyob rau ntawm lub sijhawm no, cov qauv siv quav ciab seem thiab cov khoom siv nkag tau raug tshem tawm tag nrho thiab cov pwm ceramic tseem nyob nrog cov kab noj hniav hauv cov duab ntawm qhov xav tau cam khwb cia.
Qhov kev ua haujlwm kub kub no kuj ua rau muaj zog thiab ruaj khov ntawm cov khoom siv ceramic. Tsis tas li ntawd, nws yuav pab txo qis cov tshuaj tiv thaiv ntawm lub plhaub thiab hlau thaum lub sij hawm nchuav.
E. Melt Thiab Cast
Cov pwm yog preheated rau ib tug tshwj xeeb kub thiab ntim nrog molten hlau, tsim cov hlau casting.
Yuav luag txhua cov hlau tuaj yeem tsim tau siv cov txheej txheem no. Cua melting los yog nqus melting tej zaum yuav ua hauj lwm raws li dictated los ntawm cov alloy chemistry. Lub tshuab nqus tsev melting yog siv feem ntau thaum cov khoom reactive muaj nyob rau hauv cov hlau.
F. Kev Ua Haujlwm Kawg
Thaum lub casting tau txias txaus, lub plhaub pwm yog tawg tawm ntawm lub casting nyob rau hauv ib tug knockout lag luam.
Cov rooj vag thiab cov neeg khiav dej num raug txiav los ntawm cov casting, thiab yog tias tsim nyog, qhov kawg tom qab ua tiav sandblasting, sib tsoo, thiab machining yog ua kom tiav qhov casting dimensionally.
Kev kuaj tsis muaj kev puas tsuaj yuav suav nrog fluorescent penetrant, magnetic particle, radiographic, lossis lwm yam kev tshuaj xyuas. Kev tshuaj ntsuam xyuas zaum kawg, cov txiaj ntsig ntawm kev ntsuas hlau, thiab NDT raug txheeb xyuas ua ntej xa khoom xa tuaj.
