Thaum engineers qhia a poob ciab steel casting Hoobkas, lawv tsis tsuas yog nrhiav cov hlau nchuav rau hauv pwm. Lawv xav tau kev ruaj ntseg nyob rau hauv 300 MPa hydraulic siab. Microstructure tswj hauv AMS 5387 cobalt alloy tom qab kev kho cua sov. Zero porosity nyob rau hauv 120-mm-diameter twj tso kua mis lub tog raj kheej vaj tse uas tig ntawm 1,800 RPM thaum sealing tiv thaiv abrasive slurry. Qhov ntawd yog qhov kev ua haujlwm tiag tiag - tsis yog cov ntaub ntawv xov xwm.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm ib qho chaw - ISO-certified, vertically integrated, thiab tsim nyob ib ncig ntawm kev ua hauj lwm tsis ua hauj lwm hom. Peb tau nrum T800-raws li nozzles rau offshore txhaj twj tso kua mis qhov twg 0.05 hli nto flaw ua rau muaj kev puas tsuaj puas tsuaj. Peb tau tshuab piston twj tso kua mis nrog GD&T callouts nruj dua ± 0.015 hli ntawm qhov tseem ceeb sealing bores - thiab xa thawj tsab ntawv pom zoo rau peb qhov sib law liag North American OEM cov kev pab cuam. Qhov no tsis yog theoretical muaj peev xwm. Nws yog qhov rov ua tiav raws li kev txwv hauv ntiaj teb tiag.
Yog vim li cas poob wax steel casting tsis-tshwj tsis yog tias koj tswj cov plaub levers
Feem ntau cov kev ua tsis tau zoo taug qab mus rau ib qho ntawm plaub qhov tsis sib xws: cov khoom siv tsis sib xws, cov qauv tsis sib xws, lub plhaub tsis zoo, lossis thermal mismatch thaum lub sij hawm solidification. Cov txheej txheem foundries feem ntau kho cov no raws li cov kauj ruam cais. Ntawm peb qhov chaw Qingdao, lawv muaj kev sib cuam tshuam.
- Cov khoom traceability pib ua ntej melting: Txhua AMS 5387 lossis F22 stainless ingot nqa cov ntaub ntawv kuaj xyuas zeb thiab rov xyuas dua ntawm OES spectroscopy thaum tau txais. Peb tsis lees txais cov khoom siv nrog> 0.02% sulfur sib txawv-txawm tias nyob hauv ASTM A995 txwv-vim nws ncaj qha cuam tshuam nrog kub tearing hauv nyias-walled valve lub cev.
- Qauv geometry yog tuav rau ± 0.03 hli: Peb siv CNC-machined aluminium masters-tsis yog 3D-printed resins-rau cov qauv peev siv nyob rau hauv high-volume ntau lawm. Vim li cas? Resin shrinkage txawv ntawm cov av noo thiab lub sijhawm tom qab kho; aluminium tsis muaj. Ib tus neeg European hydraulic tau txo qis lawv qhov kev tsis lees paub qhov xau los ntawm 4.2% mus rau 0.3% tom qab hloov mus rau peb cov qauv.
- Plhaub lub zog yog ntsuas - tsis xav: Peb cov txheej txheem ceramic plating-thiab-stucco suav nrog hauv-kab viscosity xyuas cov slurries thiab automated stucco particle loj tsom xam. Plhaub tau txais 24-teev cov lwg-point-tswj kom qhuav ua ntej burnout. Kev hla cov kauj ruam no ua rau micro-cracks uas dhau los ua qhov tsis muaj chaw nyob hauv qhov kawg X-ray scans.
- Solidification modeling drives gating design: Peb khiav MAGMAsoft simulations rau txhua qhov tshiab steel casting-tshwj xeeb tshaj yog rau cov qib stainless xws li CF8M qhov twg dendritic segregation cuam tshuam rau corrosion kuj. Gating systems yog optimized tsis yog rau lub sij hawm sau, tab sis rau kev taw qhia solidification rau risers. Qhov ntawd yog li cas peb ua tau zoo nyob rau hauv 85-mm-thick twj tso kua mis lub hauv paus tsis muaj HIPing theem nrab.
Qhov twg machining ntsib casting: hybrid kom zoo dua
Poob ciab casting ib leeg tsis daws qhov teeb meem. Tsis yog CNC machining. Qhov tseeb tiag los ntawm qhov lawv sib tshuam - thiab qhov ntawd yog qhov kev sib koom ua ke ntsug muab ROI ntsuas tau.
Peb nrum stainless hlau valve lub cev nrog 2.5 hli machining nyiaj pub rau ntawm lub ntsej muag sealing, ces ua tiav lawv ntawm 5-axis DMG Mori cov cav tov nruab nrog Renishaw PH10M probes. Cov diameters tseem ceeb tau txheeb xyuas qhov nruab nrab ntawm cov txheej txheem siv kov-tsim CMMs calibrated rau ISO 10360-2. Qhov tshwm sim? Tag nrho cov ntsuas ntsuas nyob qis dua 0.008 hli hla 150 hli ntev-tsis muaj kev sib tsoo. Ib lub tuam txhab lag luam Esxias sab hnub tuaj tau txiav lawv lub sijhawm txhuas tag nrho los ntawm 37% los ntawm kev sib sau ua ke thiab ua tiav machining nrog peb es tsis txhob tswj hwm ob tus neeg muag khoom.
Qhov no tsis yog hais txog kev yooj yim. Nws yog hais txog kev tshem tawm qhov yuam kev stack-up. Thaum koj tus neeg muab khoom pov thawj tuav ± 0.3 hli thiab koj lub khw muag khoom tuav ± 0.1 hli, qhov phem tshaj qhov ntsuas qhov siab dhau los ua ± 0.4 hli. Peb tuav ob txheej txheem nyob rau hauv ib lub ru tsev - thiab tswj lub datum hloov ntawm lawv. Tias yog vim li cas peb lub siab li qub raws li API 6D to Class A yam tsis muaj kev sib tw thib ob.
Dab tsi cov neeg siv khoom nug tiag tiag - thiab qhov lawv xav tau tiag tiag
"Koj puas tuaj yeem cam stainless hlau?" tsis tshua muaj nqe lus nug. Cov tiag tiag tuaj tom qab:
- "Lub tsev 316L no puas yuav khaws cov khoom muaj zog tshaj 425 ° C tom qab casting + tshuaj anneal?" → Yog - nrog tag nrho cov ntaub ntawv kho cua sov thiab cov ntaub ntawv ntsuas tensile ib daim ntawv pov thawj ASTM A370.
- "Koj puas tuaj yeem tuav 0.005 mm flatness ntawm 300 × 200 mm mounting flange?" → Tsuas yog peb tshuab nws tom qab nrum. Kev nqis peev casting ib leeg yuav tsis xa qhov ntawd. Peb mam li qhia rau koj ua ntej-thiab qhia cov qauv tsim uas ua rau nws ua tau.
- "Koj puas txhawb PPAP Qib 3?" → Yog lawm, suav nrog cov ntawv ceeb toom me me nrog CMM taw tes huab, cov ntaub ntawv pov thawj, thiab txheej txheem FMEAs. Tab sis peb kuj tseem chij uas GD&T nta yog qhov txheeb xyuas tsis ruaj khov nyob rau hauv ntau ntau thaum ntxov - thiab qhia lwm txoj kev tswj hwm.
Peb tsis muag "poob ciab steel casting." Peb muag kev ua haujlwm ruaj khov rau qhov chaw uas yuav tsum muaj sia nyob 20,000 teev hauv kev pabcuam oilfield lossis 15 xyoo hauv marine hydraulic systems. Qhov ntawd yuav tsum tsis lees txais 7.3% ntawm cov khoom lag luam cobalt-nickel raw khoom - tsis yog vim nws ua tsis tau zoo, tab sis vim tias nws cov nplej loj faib tawm sab nraum peb lub qhov rais ua pov thawj.
Xaiv koj qhov poob ciab steel casting Hoobkas txhais tau tias xaiv koj qhov kev pheej hmoo profile
Tus nqi qis qis zoo li ntxim nyiam kom txog rau thaum koj lub winch center ncej rau cov menyuam tawg thaum lub sijhawm kuaj. Txog rau thaum koj lub cobalt alloy ntsaws erodes tom qab 400 lub sijhawm ua haujlwm - tsis yog 5,000 teev. Txog rau qhov seem drift rog teb rov ua haujlwm ntawm 22% ntawm cov twj tso kua mis sib dhos.
Qhov sib txawv yog nyob rau hauv cov ntaub ntawv tswj cov txheej txheem - tsis yog kev lag luam thov. Hauv kev txheeb xyuas cov khoom ua ntej nchuav - tsis yog tom qab. Hauv GD&T-paub kev tsim qauv-tsis yog CAD txhais lus xwb. Hauv kev soj ntsuam cov txheej txheem khi rau cov hom kev ua tsis tiav - tsis yog cov ntawv txheeb xyuas dav dav.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsim kom muaj kev qhuab qhia rau txhua qhov kev txiav txim. Tsis yog ib qho add-on. Tsis yog qhov kev xaiv. Raws li lub hauv paus.
Yog tias koj daim ntawv thov xav tau qhov tshwj xeeb ntawm cov hlau uas qhov kev ua tau zoo tsis tuaj yeem sib tham tau - qhov "kaw txaus" txhais tau hais tias seem, ncua sijhawm, lossis kev pheej hmoo kev nyab xeeb - koj xav tau ntau tshaj li qhov chaw tsim khoom. Koj xav tau tus khub uas kho txhua qhov kev ua haujlwm zoo li nws yuav ua haujlwm hauv subsea tswj module ntawm 3,000 meters qhov tob. Qhov ntawd yog tus qauv peb engineer rau. Qhov ntawd yog vim li cas cov engineers rov qab - dua thiab dua - rau ib poob ciab steel casting Hoobkas uas ntsuas kev ua tiav hauv xoom teb tsis ua haujlwm, tsis yog kev xa khoom raws sijhawm.
