Thaum cov kws tshaj lij hais txog steel xuab zeb casting rau high-pressure hydraulic li qub lossis winch center shafts, lawv tsis yog xaiv cov txheej txheem xwb - lawv tab tom twv rau qhov ruaj khov, microstructure tswj, thiab batch-to-batch metallurgical sib xws. Yog vim li cas a steel xuab zeb casting Hoobkas yuav tsum ua ntau tshaj li cov hlau molten rau hauv pwm. Nws yuav tsum koom nrog kev tshawb fawb txog kev tshawb fawb nrog precision machining, cov khoom siv traceability nrog kev ua haujlwm zoo-thiab xa cov khoom uas muaj sia nyob 20,000 psi cycles yam tsis muaj kev cuam tshuam.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau pom yuav ua li cas misaligned core prints ua rau 0.15 hli phab ntsa-thickness variation nyob rau hauv piston twj tso kua mis lub tog raj kheej vaj tse - txaus ua rau cavitation ntawm 3,200 rpm. Peb kuj tau pom cov neeg siv khoom pov tseg tag nrho vim tias cobalt-nickel castings txias sai heev, ua rau nkig sigma theem raws li cov ciam teb. Cov no tsis yog qhov kev pheej hmoo theoretical. Lawv yog hom kev ua tsis tau rov ua dua - thiab lawv yog vim li cas peb qhov chaw ua raws ISO tau kho txhua txoj haujlwm steel xuab zeb ua cov ntawv cog lus metallurgical, tsis yog kev tsim khoom.
Peb ntsug kev koom ua ke tshem tawm cov ntsiab lus mob feem ntau nyob rau hauv high-alloy casting mov chains. Foundry, kho cua sov, multi-axis CNC, thiab nto tiav tag nrho tshwm sim nyob rau hauv ib lub ru tsev - nrog sib koom GD&T qauv, synchronized soj ntsuam raws tu qauv, thiab real-time CMM tawm tswv yim looped rov qab rau pwm tsim. Thaum koj xaj AMS 5387 cobalt alloy twj tso kua mis, tib tus kws ua haujlwm uas siv tau koj daim duab kos kuj tau kos npe tawm ntawm lub cav rauv, tus nqi quench, thiab qhov kawg Rockwell C hardness test. Tsis muaj handoffs. Tsis txhais lus poob. Tsuas yog ib pab neeg lav ris.
- Cov khoom siv ncaj ncees pib ua ntej melting: Peb muab ntawv pov thawj T800 cobalt-raws li thiab stainless hlau ingots nrog tag nrho cov ntawv xeem zeb-tsis yog cov npe qib. Txhua batch tau soj ntsuam spectrographic thaum tau txais, thiab peb khaws cov qauv rau 5 xyoos.
- Sand casting tsis yog "tsawg-precision" ntawm no: Peb cov qauv ntsuab-xuab zeb thiab resin-bonded qauv ua tiav ± 0.3 hli linear kam rau ua ntawm 300 hli nta-nruj dua li ntau cov peev txheej casters thov rau cov hlau zoo sib xws-vim peb tswj cov dej noo, compression siab, thiab shakeout sij hawm mus rau qhov thib ob.
- Machining ua raws li casting - tsis yog lwm txoj hauv kev: Peb tshuab qhov tseem ceeb sealing nto * tom qab * kev ntxhov siab-relieving thiab aging, tsis ua ntej. Qhov ntawd tiv thaiv kev tsis sib haum xeeb hauv lub cev lub siab lub cev qhov twg 0.02 mm flatness sib txawv ua rau xau tshaj 10,000 psi.
Qee tus yuav sib cav hais tias xuab zeb casting tsis tuaj yeem sib tw peev casting rau txoj kev geometry. Tab sis hauv kev xyaum, peb tsim cov twj tso kua mis uas tsis yog tus qauv nrog cov cua txias sab hauv, undercuts, thiab kev sib koom ua ke mounting lugs-siv split-pattern tooling thiab ceramic cores-thaum tuav qhov sib txawv ntawm ± 1.2%. Qhov txawv? Peb tsis kho geometry raws li qhov txwv. Peb kho nws raws li tus qauv tsim yuav tsum tau engineered nrog thermal gradient thiab solidification txoj kev.
Kev ua tau zoo tsis tau tshawb xyuas thaum kawg - nws tau ua rau hauv txhua lub rooj vag. Cov ntaub ntawv raw khoom pov thawj. Nyob rau hauv cov txheej txheem radiographic tshuaj xyuas ntawm qhov tseem ceeb ntawm cov hlau thiab stainless hlau castings. Kev sim ua haujlwm kawg: hydrostatic siab tuav ntawm 1.5 × ntsuas kev ua haujlwm siab rau 30 feeb, nrog xoom npuas emission. Txhua daim ntawv tshaj tawm muaj ntau tus lej, tus lej xov tooj cua sov, tus neeg teb xov tooj ID, thiab lub sijhawm teev. Txhua feem yog traceable - tsis yog rau lub batch xwb, tab sis mus rau lub caij nyoog rau lub cub tawg thiab quench tank siv.
Peb pab engineering tsheb OEMs uas xav tau winch center ncej chais nrog 62 HRC nto hardness thiab ib tug 0.4 µm Ra tiav - ntawm txhuas lub sij hawm luv luv tshaj ntiaj teb no cov neeg sib tw hais rau prototypes. Peb txhawb nqa hydraulic system integrators uas yuav tsum tau lub siab li qub nrog interchangeable rooj inserts machined los ntawm tib casting kub li lub cev - kom ntseeg tau zoo tib yam thermal expansion cwj pwm. Thiab peb koom tes nrog cov khoom siv roj & roj uas xav tau AMS 5387 nozzles nrog xoom porosity hauv caj pas, txheeb xyuas los ntawm micro-CT scanning.
A steel xuab zeb casting Hoobkas khwv tau kev ntseeg tsis yog los ntawm daim ntawv qhia - tab sis los ntawm qhov nws ua thaum daim ntawv spec tawm hauv chav rau kev txhais lus. Thaum koj daim duab hais tias "R0.5 max," peb xyuas seb lub vojvoog ntawd puas cuam tshuam rau kev sib cais hauv koj lub twj tso kua mis - thiab qhia R0.8 yog cov ntaub ntawv qhia tias nws txhim kho kev ua haujlwm ntawm 3.7%. Thaum koj lub sijhawm xav tau kev xa khoom thawj zaug hauv 18 hnub, peb rov ua cov txheej txheem kho cua sov kom tsis txhob muaj lub sijhawm txias txias-tsis muaj lub zog tensile.
Saib tom ntej, peb tab tom sib sib zog nqus peb txoj haujlwm ntawm hybrid casting-machining txheej txheem: embedding machined alignment dowels ncaj qha mus rau hauv cov xuab zeb pwm, siv nyob rau hauv-situ thermal xyuas los kho tus nqi cua txias nruab nrab-ntws, thiab tsim nyog tshiab binder systems rau finer nto finishes ntawm loj-section carbon hlau castings. Cov no tsis yog kev sim hauv lab. Lawv yog cov kev daws teeb meem-kuaj ntawm 42-tuj engineering tsheb thav duab thiab subsea twj tso kua mis sib dhos ntsuas rau 3,000 meters qhov tob.
Yog tias koj qhov project tom ntej no suav nrog cov hlau lossis cov hlau tsis muaj steel hlau uas yuav tsum tau ua nyob rau hauv siab, hnav, lossis corrosion - tsis txhob khom rau tus neeg muag khoom uas pom kev ua haujlwm ib leeg. Xaiv ib tus khub uas kho txhua lub ncuav los ua thawj qhov sib txuas hauv cov saw hlau ntawm qhov tseeb, kev lav phib xaub, thiab muaj pov thawj kev ua haujlwm zoo.
