Puas yog cov ua ke ntawm kev siv kiv cua thiab cov khoom siv tshuab tsim kom haum rau kev siv hlau 3DT?

一, kev hloov kho tau: Yuav ua li cas hlau 3D luam ntawv tuaj yeem tau txais ib puag ncig cov teeb meem uas tuaj hauv kev tsim khoom ib txwm muaj
1. Moulding ntawm cov ntawv sau tag nrho ib zaug
Fans and pump casings often need complicated shapes, like built-in flow channels, heat sinks, and installation interfaces. Tsoos thev naus laus zis xav tau modular ua khoom siv thiab kev sib txoos, tab sisHlau 3D Printing(xws li xaiv Laser Melting SLM thev naus laus zis) tuaj yeem muab kev sib xyaw ua ke ntawm cov pa ntws sab hauv thiab cov plhaub sab nraud los ntawm kev luam ntawv. Piv txwv li, tom qab 3D luam tawm lub tshuab nqus dej casing casing rau lub zog hluav taws xob, cov yeeb yaj kiab ntws channel uas siv los xav tau 12 ntu tau sib xyaw ua ke. Qhov no txiav qhov hnyav los ntawm 40% thiab cov kua dej tsis kam los ntawm 15%, thiab nws kuj tau tshem ntawm kev pheej hmoo ntawm kev muaj kev ntxhov siab uas los nrog kev siv vuam.
2. Txhim kho cov ntaub ntawv ua tau zoo
Lub casing yuav tsum muaj peev xwm tiv taus corrosion, kub siab, thiab muaj ntau lub siab nyob rau hauv ib qho chaw muaj kev lag luam. Cov tshuab luam ntawv hlau yuav ua haujlwm siab yuav ua haujlwm siab xws li cov hlau stainless, nickel {}}} raws li alloys, thiab titanium alloys. Nws kuj tseem tuaj yeem nce kev ua tau zoo thiab ua kom cov nplej ua kom zoo los ntawm kev tswj cov txheej txheem txheej txheem. Lub zog tensile ntawm cov luam tawm ua los ntawm inconel 718, ib npib tsib, tseem tuaj yeem ua tiav 1000mpa ntawm qhov kub ntawm 650 degree. Qhov no yog siab dua 800MPA ntawm cov chaw ua yeeb yam, uas yog dab tsi petrochemicals, roj turbines, thiab lwm yam haujlwm yuav tsum tau.
3. Lub luag haujlwm thiab cov ntsiab lus txhim kho
Hlau 3D Printing Yuav ua tau "on -}} Thov sau" ua tsaug rau topology tsim kho software. Piv txwv li, ib hom kiv cua twv siv cov qauv muaj ntxaij ua rau cov chaw uas tsis xav txhawb nqa qhov hnyav. Qhov no txiav qhov hnyav los ntawm 35% thaum ua kom lub cev tawv tawv. Cov qauv dej muaj cov kua dej kuj tseem pab txhim kho cov qauv ntawm cov khoom kub dissipation channel kev ua haujlwm los ntawm 8℃thiab xaiv nws txoj kev ua tau zoo los ntawm 5%.
4. Kev tiv thaiv ceev ceev thiab ua cov khoom kom
Feem ntau nws yuav siv sijhawm li 3 txog 6 hlis los ua pwm, tab sis cov luam ntawv 3D tau ua nws tsuas yog 48 rau 72 teev, los ntawm kev tsim qauv. Ib lub tuam txhab uas ua rau twj thiab cov li qub tau txiav lub sijhawm nws yuav ua kom lub plhaub ntawm cov dej hiav txwv tshiab uas tau tso kua mis los ntawm 90 hnub siv 3D luam luam ntawv thev naus laus zis. Lawv kuj tau sai sai tsim kev hloov kho lub cev sib txawv lub cev cov lus qhia kom tau raws li qhov xav tau ntawm lub platform ntawm ntug dej thiab lwm yam xwm txheej.
2, tsom xam ntawm ib qho xwm txheej: Cov kev coj ua los ntawm kev kuaj kom muaj kev lag luam
Rooj plaub 1: ib kauj ruam loj rau hauv kev ua nuclear power lub zog tej teeb meem tsis muaj pwm
Yav qab teb ntxiv Technology siv hnyav {{} Duty works hlau 3D tshuab hluav taws xob uas yuav tsim hluav taws xob lab ntawm hluav taws xob. Txoj kev qub ntawm kev ua haujlwm siv 180 tuj ntawm cov hlau sib xyaw ua ke thiab siv sijhawm ntev thiab ua rau muaj rau 6 lub sijhawm, ua rau kev siv cov khoom siv cua sov los ntawm 15% mus rau 95%. Cov luam tawm qhov chaw dhau mus kuaj rau tensile zog, cuam tshuam kev cuam tshuam nyuaj, thiab lwm yam kev ntsuas. Lawv tau zoo dua li cov lus tsis lees paub thiab tau ntsib cov kev qhia tshwj xeeb rau Nuclear kev nyab xeeb qib ib cov khoom.
Lub "kev ntse tsim kho" kev hloov kho ntawm cov txheej txheem nkoj uas tsim tau "Micro Casting forging" Cov tshuab no tau dhau ntawm cov teeb meem uas cov qauv txheej txheem muaj nrog cov khoom loj. Nws ua rau cov khoom siv 30% muaj zog dua, nce ntau lawm tsim tau ntawm 0.5mm rau 0.1mm, thiab tau tshem tawm txhua yam zoo li pores thiab nrws. Txoj cai tam sim no, cov thev naus laus zis tsim nyog tau siv rau cov kws nqa dav hlau hauv tsev, LNG cov khoom siv, thiab lwm cov khoom siv hauv tebchaws.
Rooj plaub 3: "Kev Tsim Kho Mob Tawm Tsam" twj rau roj drilling
Npaj drilling, ib lub tuam txhab South African uas ua rau cov khoom siv mining, yuav tsum tau kho kho cov iav iav sai ntawm lub tshuab raj drilling. Tus qauv casting txheej txheem yuav siv peb lub hlis kom xa. Nrog Desktop Hlau Lub Studio 3D luam ntawv tshuab, luam tawm, sinterting, thiab kev kho cua sov ntawm peb lub lis piam siv cov hmoov hlau uas muaj tshuaj txia. Lub iav saum npoo hardness nce mus txog 64 hrc tom qab ntshav nitriving, uas yog qhov nyuaj dua 45 hrc ntawm qhov uas tau raug muab tso rau hauv txoj kev niaj zaus. Tus nqi nqes mus los ntawm 60% thiab lub sijhawm khoom xa tuaj mus rau 80% nyob rau tib lub sijhawm.
3, cov qauv zoo thiab teeb meem hauv kev lag luam: los ntawm kev siv thev naus laus zis los siv nws ntawm cov nplai loj
1. Kev loj hlob ntawm cov khoom siv
Tam sim no, cov luam ntawv hlau suav nrog cov khoom lag luam uas suav nrog cov hlau stainless, alloys alloys, Nickel- raws li alloys, thiab ntau dua. Lawv maj mam ntxiv cov ntaub ntawv tshiab xws li siab -} Entropy alloys thiab amorphous alloys. Piv txwv li, ib lub tuam txhab tau tsim qhov siab - Entropy alloy rau qhov ntsuas kub ntawm 600℃{}} raws li alloys. Cov ntaub thaiv no tuaj yeem siv tau cov xwm txheej hnyav, zoo li cov cav lim dej hauv av.
2. Ib kauj ruam loj rau pem hauv ntej hauv multi-} cov khoom siv tshuab
Gradient Transition lossis sib xyaw cov luam tawm ntawm ntau cov ntaub ntawv hlau yog ua tau nrog Kev Tshaj Tawm Lub Zog (DED) thev naus laus zis. Lub foob pob zeb nozzle, piv txwv li, muaj sab hauv txhuas txias channel thiab sab nrauv inconel 625 {}} tiv taus txheej. Lub thermal conductivity yog txhim kho los ntawm 40% thiab cov khoom siv lub zog ncav cuag 1200 MPa, uas tau raws li kev tiv thaiv thermal. Qhov no yog ua los ntawm kev luam ntawv hauv txheej thiab cua sov cov khoom siv.
3. Ua rau cov kev tswj hwm zoo dua ua kom zoo dua thiab zoo dua
Qhov zoo traceazeobility, txheej txheem saib xyuas, thiab tsis yog- Lub Tuam Txhab Ua Haujlwm Zoo Li Cas thiab yog cov hmoov av agglomeration thiab ib lub tshuab tsis ruaj khov thiab ib lub taub dej khov kho thaum lub sijhawm luam ntawv. Qhov system no tseem tseem tuaj yeem txhim kho qhov tseeb ntawm kev lees paub txog thaum 99.5%, uas ua kom zoo rau kev loj {6} nplai ntau lawm.
4. Coob tus nqi sib tw
Tus nqi yuav cov hlau 3D luam tawm tau ploj mus los ntawm ntau dua 50% txij li Huhlu thiab Huhlu Tech pib ua rau lawv nyob hauv Asmeskas. Nyob rau tib lub sijhawm, ua kom zoo rau cov hmoov ua dua tshiab tus txheej txheem (piv txwv li, los ntawm kev siv cov roj ntsha txiav roj av los ntawm 30%. Thaum cov pob loj loj tshaj li 500 yam, tag nrho cov nqi luam tawm me me, cov twj tso kua mis me me yog li ntawm cov txheej txheem ib txwm muaj, raws li kev suav.
