Thaum engineers qhia colloidal silica peev casting rau cov hlau uas muaj kev ncaj ncees siab, lawv tsis yog xaiv cov txheej txheem xwb-lawv xaiv qhov kev lees paub ua haujlwm. Dimensional stability nyob rau hauv thermal cycling. Nto tiav uas tshem tawm tom qab kev sib tsoo. Microstructure tswj nyob rau hauv cobalt alloys qhov twg txhua qhov kev ciam teb tseem ceeb. Cov no tsis yog theoretical zoo. Lawv yog cov txiaj ntsig peb pom txhua hnub hauv peb qhov chaw ua haujlwm ISO-raws li hauv Qingdao-qhov twg txhua pawg ntawm AMS 5387 cobalt alloy twj tso kua mis vaj tsev lossis T800 nozzle dhau los ntawm peb qhov kev tshuaj xyuas CMM ua ntej tawm hauv kab.
Yog vim li cas colloidal silica peev casting xa qhov twg lwm txoj hauv kev
Colloidal silica slurries tsim muaj zog, ntau thermally ruaj khov ceramic shells dua li cov tsoos ethyl silicate binders. Lub zog ntawd txhais ncaj qha mus rau hauv lub plhaub tsawg dua thaum lub sij hawm dewaxing thiab firing - thiab xoom kam rau distortion nyob rau hauv nyias-walled lub tog raj kheej vaj tse nyob rau 420 bar hydraulic kev pab. Peb tau ntsuas lub plhaub nthuav dav ntawm 0.012% ib ° C txog 1100 ° C; cov neeg sib tw siv dej-iav lossis alumina-bonded systems feem ntau tshaj 0.035%. Qhov txawv ntawd? Nws yog qhov sib txawv ntawm kev ntaus ± 0.05 hli GD&T ntawm 320 hli piston twj tso kua mis tsev nyob - thiab muab pov tseg tom qab kuaj thawj zaug.
Peb tsis khiav colloidal silica casting raws li ib tug standalone kab. Nws tau ua ke nrog precision CNC machining nyob rau hauv ib qho kev ua haujlwm: nrum cov tub ntxhais geometry, tshuab tseem ceeb sealing nto thiab xov cov ntaub ntawv, tom qab ntawd siv cov kev kho cua sov * tsis muaj kev sib tsoo *. Tsis muaj handoffs. Tsis muaj ntaub ntawv rov txheeb xyuas dua. Txhua feem nqa ib lub laser-etched ntau ID txuas rov qab mus rau cov ntaub ntawv pov thawj raw khoom, lub plhaub ntim cov cav, cov kab kos rauv, thiab cov ntaub ntawv CMM kawg.
Qhov kev sib koom ua ke no daws qhov mob tiag tiag: warpage hauv high-alloy steel castings. Ib tus neeg siv khoom ib zaug coj peb lub cev stainless hlau valve uas warped 0.18 hli tom qab kev ntxhov siab - vim tias lawv cov neeg muab khoom pov tseg, xa khoom, thiab cia cov neeg siv khoom kho cua sov sib cais. Peb rov hais dua siv T800-qib cov khoom noj zoo ib yam, tab sis tuav qhov hauv peb lub tshuab nqus tsev tam sim tom qab shakeout. Qhov kawg distortion: 0.023 mm. Tsis yog khawv koob. Tsuas yog tswj cov keeb kwm thermal-thiab tag nrho cov txheej txheem ua tswv cuab.
Dab tsi ua rau muaj tseeb colloidal silica peev casting Hoobkas txawv
Ntau lub khw hu lawv tus kheej "kev nqis peev casting factories." Ob peb tus kheej muaj cov colloidal silica slurry formulation, plhaub kom qhuav raws tu qauv, thiab dewaxing ramp profiles uas txhais tau tias zoo nrog superalloys. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb ntsuas viscosity txhua lub limtiam siv Brookfield viscometers, saib xyuas pH drift nyob rau lub sijhawm, thiab tsis lees txais cov slurry batch sab nraum 9.2–9.6 pH - txawm tias nws zoo meej. Vim li cas? Vim tias pH hloov pauv silica particle zeta muaj peev xwm, uas hloov lub plhaub ntom ntom, permeability, thiab thaum kawg, nto roughness (Ra) ntawm cov khoom tiav. Peb tau pom Ra dhia ntawm 1.8 µm mus rau 4.3 µm thaum pH drifted rau 9.8.
Peb kuj kho lub plhaub tua hluav taws ua metallurgy - tsis yog ceramics xwb. Peb lub qhov cub ramp ntawm ≤60 ° C / teev txog 1050 ° C, tuav rau 90 feeb, ces txias ntawm ≤40 ° C / teev. Lub voj voog qeeb ntawd tiv thaiv microcracking hauv cov ntu tuab ntawm cobalt-nickel castings. Ib lub twj tso kua mis European OEM hloov mus rau peb tom qab ob tus neeg muag khoom ua ntej xa cov khoom tawg tawg AMS 5387 impeller hubs. Lawv lub hauv paus ua rau kev tsom xam pom tau tias thermal poob siab tawg los ntawm lub plhaub-rau-hlau interfaces. Peb qhov kev tua hluav taws tshem tawm lawv. Tsis yog los ntawm kev hloov cov alloy - tab sis los ntawm kev hwm yuav ua li cas lub plhaub ua pa.
- Cov ntaub ntawv pov thawj nkaus xwb-txhua lub coil traceable rau mill test reports
- Tsis muaj subcontracted plhaub ua los yog dewaxing - 100% kev tswj hauv tsev
- GD&T-kev tshuaj xyuas thawj zaug: peb chij lub kaum sab xis hauv qab 0.5 ° ua ntej kev pib pib
- Surface tiav validation ntawm optical profilometers - tsis yog kev kuaj pom
Cov ntawv thov tiag tiag hauv ntiaj teb qhov twg colloidal silica casting ua pov thawj tsis yog sib tham
Lub siab li qub rau offshore roj & roj manifolds xav kom tsis muaj kev ua haujlwm ntawm -46 ° C txog + 121 ° C. Xuab zeb casting tsis tuaj yeem tuav lub 0.02 hli lub rooj concentricity xav tau. Txheem peev casting tawm tsam nrog cov thermal loj ntawm ASTM A494 M35-1 vaj tsev. Colloidal silica ua ob qho tib si: nruj tolerances * thiab * tawg-dawb kev ncaj ncees hla huab cua gradients.
Peb nyuam qhuav tsim cov ncej ncej rau engineering tsheb winch systems-qhov chaw nrog 220 hli OD, 45 hli phab ntsa tuab, thiab sab hauv spline geometry. Cov neeg siv khoom xav tau hardness ≥58 HRC * dhau ntawm ntu *, tsis yog rooj plaub-hardened xwb. Colloidal silica enabled uniform plhaub thickness, zoo ib yam solidification tus nqi, thiab xoom porosity nyob rau hauv qhov tseem ceeb load-bearing cheeb tsam. Lub sijhawm machining poob 37% piv rau cov xuab zeb-cam khwb cia vim tias peb tau xa cov duab ze-net nrog kev kwv yees cov khoom xa tawm.
Lwm qhov kev siv pov thawj muaj xws li:
- Cobalt alloy nozzles rau high-ceev abrasive slurry twj (T800 qib, 62-65 HRC)
- Pump foundations xav tau flatness ≤0.08 hli tshaj 850 hli ntev
- Tsis yog-tus qauv piston pas nrig nqa nrog kev sib xyaw ua ke cua txias-cam khwb cia, tsis welded
Xaiv koj cov colloidal silica peev casting Hoobkas tsis yog hais txog lub peev xwm - nws yog hais txog kev txawj ntse
Yog tias koj qhov yuav tsum tau AMS 5387, T800, lossis UNS R30005 - thiab yuav tsum muaj sia nyob 10,000+ lub voj voog siab yam tsis muaj kev pib microcrack - koj xav tau ntau tshaj qhov chaw tsim khoom. Koj xav tau ib tus khub uas kho colloidal silica tsis yog ib qho kev khi, tab sis raws li kev sib txawv ntawm cov hlau. Leej twg validates lub plhaub lub zog nrog ASTM C133 compression tests - tsis yog kev soj ntsuam pom. Leej twg txuas txhua qhov tsis xws luag rau qhov kev hloov pauv tshwj xeeb: lub hnub nyoog slurry, dewaxing tus nqi, lossis txawm tias ambient humidity thaum dipping.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm li ntawd - tsis yog vim nws yooj yim, tab sis vim tias lub luag haujlwm tseem ceeb ntawm cov khoom tsis muaj chaw rau kev xav. Peb luam tawm peb cov txheej txheem colloidal silica qhov rais. Peb muab cov ntaub ntawv plhaub ntom ntom nrog cov neeg siv khoom. Peb cia engineers soj ntsuam peb CMM calibration cav. Cov pob tshab ntawd tsis yog kev lag luam. Nws yog li cas koj paub tseeb tias "colloidal silica peev casting Hoobkas" ntawm daim ntawv sib tw ua haujlwm hauv khw hauv pem teb.
Rau precision hlau qhov chaw uas tsis ua hauj lwm tsis yog ib qho kev xaiv, lub Hoobkas txoj cai tsis yog cam khwb cia hlau. Nws muab kev ntseeg siab.
