Txheej txheem cov kauj ruam ntawm Poob-Wafer Casting ntawm Titanium Alloy rau Micro-Turbines
o. Pwm Tsim: Ua ntej, raws li micro- turbine tsim cov duab kos, 3D qauv yog tsim siv lub computer-aided design (CAD) software los txiav txim qhov tseeb qhov ntev thiab cov duab ntawm cov qauv siv quav ciab. Xav txog yam xws li shrinkage thaum lub sij hawm casting txheej txheem, cov qauv qhov ntev yog hloov kho kom tsim nyog.
o. Mould Manufacturing: Siv CNC machining lossis lwm txoj hauv kev, tus qauv tsim tau hloov mus rau hauv pwm tiag tiag. Pwm cov ntaub ntawv feem ntau yog xaiv los ntawm aluminium alloys kom muaj zog txaus thiab precision.
o. Kev Txhaj Tshuaj Ciab: Cov quav ciab tau rhaub rau qhov kub kom tsim nyog kom ua tau zoo fluidity. Tom qab ntawd, cov khoom siv quav ciab yog txhaj rau hauv pwm siv lub tshuab txhaj tshuaj molding. Nws yog tuav nyob rau hauv siab thiab kub rau ib lub sij hawm ntawm lub sij hawm los xyuas kom meej cov wax tag nrho nyob rau hauv lub pwm kab noj hniav. Tom qab cov quav ciab txias thiab solidifies, cov pwm qhib thiab cov qauv siv quav ciab raug tshem tawm.
o Wax Model Finishing: Cov qauv siv quav ciab tshem tawm raug tshuaj xyuas thiab ua tiav, tshem tawm ntau dhau flash, burrs, thiab lwm yam, kom ntseeg tau qhov tseeb qhov tseeb thiab qhov zoo ntawm cov qauv siv quav ciab raws li qhov yuav tsum tau ua.
o Xaiv lub Gating System: Raws li cov duab, qhov loj me, thiab qhov hnyav ntawm lub micro turbine, xaiv qhov rooj vag uas tsim nyog, suav nrog sprues, runners, thiab ingates. Lub rooj vag system tsim yuav tsum xyuas kom meej tias cov hlau molten nyob rau hauv cov kab noj hniav kom du thiab sib npaug, tsis txhob muaj qhov tsis xws luag xws li turbulence thiab cua nkag.
o Welding Wax Models: Ntau cov qauv siv quav ciab txuas nrog lub rooj vag kaw lus los ntawm kev vuam los ua ib qho kev ua tiav. Thaum lub sij hawm vuam, nws yog ib qho tseem ceeb kom ntseeg tau tias muaj kev sib txuas ruaj khov thiab kev sib khi zoo ntawm cov qauv siv quav ciab thiab lub qhov rooj kaw lus kom tiv thaiv kom tsis txhob tawg thaum lub plhaub tom ntej - ua cov txheej txheem.
o. Kev Siv Cov Txheej Txheem Sab saum toj: Cov pwm sib dhos yog muab tso rau hauv cov txheej txheem tshwj xeeb sab saum toj, kom ntseeg tau tias muaj txheej txheej txheej ntawm cov qauv siv quav ciab. Cov txheej sab saum toj feem ntau muaj cov ntaub ntawv refractory (xws li zircon hmoov), binders (xws li iav dej los yog silica sol), thiab cov khoom ntxiv. Nws qhov loj me me kom ntseeg tau qhov zoo ntawm qhov casting. Tom qab txheej txheej, ib txheej ntawm cov xuab zeb zoo yog nchuav rau ntawm cov pwm sib dhos kom ua rau cov txheej tuab thiab lub zog.
o. Qhuav thiab Hardening: Cov pwm sib dhos nrog cov txheej txheem saum toj kawg nkaus yog muab tso rau hauv lub tshuab ziab khaub ncaws kom qhuav thiab tawv hauv qhov kub thiab txias. Lub sij hawm ziab thiab tawv tawv yog nyob ntawm hom txheej thiab ib puag ncig, feem ntau yog li ntawm ob peb teev mus rau kaum teev.
o. Siv Cov Txheej Txheem Rov Qab: Tom qab cov txheej txheej saum toj kawg nkaus tau qhuav thiab tawv, cov txheej txheej rov qab yog siv ua ntu zus. Cov txheej sab nraub qaum muaj cov coarser-cov ntaub ntawv refractory, feem ntau ua haujlwm kom muaj zog thiab rigidity ntawm lub plhaub. Txoj kev siv cov txheej txheem rov qab zoo ib yam li cov txheej txheem saum toj kawg nkaus. Tom qab txhua txheej txheej, sanding thiab ziab / hardening yog yuav tsum tau. Feem ntau, ntau txheej txheej rov qab yog xav tau kom txog thaum lub plhaub pwm nce mus txog qhov tuab txaus.
o Steam Dewaxing: Lub plhaub pwm npaj tau muab tso rau hauv lub lauj kaub dewaxing, thiab siab - siab zog tau qhia, ua rau cov qauv siv quav ciab yaj thiab ntws tawm ntawm lub plhaub pwm. Qhov zoo ntawm chav dewaxing yog nws qhov ceev ceev, kev ua haujlwm siab, thiab kev puas tsuaj tsawg rau lub plhaub pwm.
o Kub Dej Dewaxing: Lub plhaub pwm tuaj yeem muab tso rau hauv dej kub, ua rau cov qauv siv quav ciab yaj thiab ntab rau saum npoo, yog li ua tiav dewaxing. Cov khoom siv dej kub dewaxing yog qhov yooj yim thiab pheej yig, tab sis lub sij hawm dewaxing yog ntev dua thiab nws muaj teeb meem xws li pwm plhaub tawg.
o Thaum tshav kub kub: Lub plhaub dewaxed pwm yog muab tso rau hauv lub cub tawg thiab cua sov maj mam ntawm tus nqi tswj. Qhov no tso cai rau cov dej noo thiab cov seem nyob hauv lub plhaub pwm kom tag nrho evaporate, thaum tib lub sijhawm ua rau muaj tshuaj lom neeg hauv cov ntaub ntawv, txhim kho lub zog thiab refractoriness ntawm pwm plhaub. Cov cua kub yuav tsum tsis txhob ceev heev kom tsis txhob tawg ntawm lub plhaub pwm vim yog thermal stress ntau dhau.
o Tuav theem: Tom qab qhov kub ntawm lub cub tawg mus txog qhov ntsuas kub ntawm qhov hluav taws kub, tuav nws rau ib lub sij hawm kom cia lub plhaub pwm kom tag nrho sinter. Kev tua hluav taws kub thiab tuav lub sijhawm yog nyob ntawm cov khoom siv ntawm lub plhaub pwm thiab qhov yuav tsum tau ua ntawm cov casting. Feem ntau, qhov hluav taws kub kub ntawm 800-1200 degree, thiab lub sijhawm tuav yog 1-3 teev.
o Lub caij txias: Tom qab tua hluav taws, maj mam txo qhov kub ntawm lub cub tawg kom cia lub plhaub pwm kom txias maj mam. Cov cua txias yuav tsum tsis txhob nrawm dhau kom tsis txhob tawg ntawm lub plhaub pwm.
o Titanium alloy melting: Muab cov titanium alloy raw khoom rau hauv cov khoom siv melting xws li lub tshuab nqus tsev induction rauv thiab yaj nws nyob rau hauv lub tshuab nqus tsev los yog inert gas tiv thaiv. Thaum lub sij hawm melting txheej txheem, nruj me ntsis tswj qhov kub, lub sij hawm, thiab alloy muaj pes tsawg leeg los xyuas kom meej qhov zoo ntawm titanium alloy.
o Casting: Tom qab cov titanium alloy tau melted mus rau ib tug haum kub thiab fluidity, ncuav nws mus rau hauv lub preheated pwm plhaub. Thaum lub sij hawm pouring, xyuam xim rau lub pouring ceev thiab txoj kev kom tsis txhob molten hlau cuam tshuam lub puab plhaub, uas yuav ua rau lub plhaub puas los yog ua rau lub cev tsis xws luag.
o Cov xuab zeb tshem tawm: Tom qab lub casting tau txias thiab solidified, tshem tawm cov pwm plhaub thiab cov xuab zeb core siv txoj kev xws li vibration xuab zeb tshem tawm los yog tua blasting kom nthuav tawm cov casting nto.
o Gating Cutting: Siv cov cuab yeej txiav los cais cov casting los ntawm lub rooj vag.
o Kev kho cua sov: Raws li kev ua tau zoo ntawm cov titanium alloy, ua cov kev kho cua sov kom tsim nyog ntawm cov casting, xws li kev kho kev daws teeb meem thiab kev laus kev kho mob, los txhim kho lub zog, hardness, thiab toughness ntawm casting.
o Machining: Ua qhov tsim nyog machining ntawm qhov casting, xws li tig, milling, thiab sib tsoo, kom ua tiav qhov tseeb qhov tseeb thiab qhov roughness ntawm qhov tsim.
o Kev tshuaj xyuas: Ua ib qho kev tshuaj xyuas tag nrho ntawm cov casting, nrog rau kev ntsuas qhov loj me, kev tshuaj xyuas qhov muag, kev tshuaj ntsuam metallographic, thiab tsis yog -kev kuaj kev puas tsuaj, los xyuas kom meej tias cov casting zoo raws li cov qauv thiab kev siv.

Haum rau kev tsim khoom loj
Los ntawm kev tsim pwm thiab cov qauv, kev tsim khoom loj ntawm micro-turbines tuaj yeem ua tiav, txhim kho kev tsim khoom thiab txo cov nqi tsim khoom.
Kev Sib Tw ntawm Poob - Wafer Casting ntawm Micro-Turbine Titanium Alloys
Nyuaj hauv Melting thiab Casting Titanium Alloys
Titanium alloys muaj tshuaj lom neeg muaj zog thiab yooj yim ua rau cov ntsiab lus xws li oxygen thiab nitrogen hauv huab cua thaum lub sij hawm melting thiab casting, tsim impurities xws li oxides thiab nitrides, uas cuam tshuam rau kev ua tau zoo ntawm cov castings. Yog li ntawd, melting thiab casting yuav tsum tau nqa tawm nyob rau hauv lub tshuab nqus tsev los yog inert gas tiv thaiv, muab siab xav tau ntawm cov khoom thiab cov txheej txheem.
Nyuaj hauv plhaub zoo tswj
Qhov zoo ntawm lub plhaub ncaj qha cuam tshuam rau qhov zoo ntawm casting. Lub plhaub lub zog, permeability, thiab thermal stability yuav tsum tau tswj nruj heev. Thaum lub plhaub ua, yam xws li txheej txheej txheej, txheej txheej txheej, thiab ziab thiab hardening tej yam kev mob cuam tshuam rau lub plhaub zoo, yuav tsum tau tswj cov txheej txheem meej.
Casting defect tswj
Porosity, shrinkage kab noj hniav, thiab cov kab nrib pleb yog nquag tshwm sim thaum lub sij hawm poob - ciab casting ntawm micro- turbine titanium alloys, yuav tsum muaj kev tswj xyuas zoo. Piv txwv li, optimizing lub gating system tsim, tswj melting thiab pouring kub, thiab kev txhim kho lub plhaub permeability yuav txo tau casting defects.
