Txhua lub tuam txhab hlau casting pib nrog tib lo lus nug: Yuav ua li cas koj tig molten hlau mus rau hauv ib feem uas yuav tsis tawg nyob rau hauv 300 bar ntawm hydraulic siab - los yog ciaj sia 10,000 teev nyob rau hauv qaub roj kev pab cuam? Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau cam khwb cia thiab machined tshaj 12,000 lub siab li qub, piston twj tso kua mis, thiab cobalt-alloy nozzles txij li thaum 2015. Peb tau pom cov xuab zeb pwm poob ntawm 1,150 ° C ncuav kub. Peb tau muab pov tseg 47% ntawm AMS 5387 batch tom qab kev tsom xam microstructure qhia kev sib cais sib cais. Cov no tsis yog cov ntaub ntawv kawm-lawv yog cov kev txiav txim siab txhua hnub uas txhais tau tias cov hauv paus ntsiab lus ntawm hlau casting Hoobkas kev ua haujlwm.
Cov Khoom Siv Kev Ncaj Ncees Tsis Xav Tau - Nws tau lees paub
Koj tsis tuaj yeem nrum qhov ua tau zoo los ntawm "generic stainless hlau." Ntawm peb lub chaw Qingdao, txhua qhov cua sov ntawm T800 cobalt-raws li alloy tuaj txog nrog tag nrho cov ntawv soj ntsuam zeb - thiab peb rov ntsuas cov pa roj carbon, chromium, thiab cov ntsiab lus tungsten ua ntej yaj. Vim li cas? Vim tias qhov sib txawv ntawm 0.03% hauv cov ntsiab lus cobalt hloov cov khoom kub ntawm 12 ° C. Qhov ntawd hloov pwm txias tus nqi. Qhov ntawd cuam tshuam cov qoob loo loj. Qhov ntawd cuam tshuam lub neej qaug zog hauv winch center ncej chais. Peb siv OES (Optical Emission Spectrometry) ntawm cov khoom xa tuaj thiab txheeb xyuas ASTM A957 rau kev nqis peev castings, ASTM A159 rau grey hlau, thiab AMS 2269 rau cobalt-nickel alloys. Tsis muaj kev zam. Tsis muaj "kev ntseeg tab sis lees paub"-peb txheeb xyuas ua ntej, tom qab ntawd pov tseg.
Casting txheej txheem xaiv dictates ib feem muaj peev xwm
Xuab zeb casting tuav cov twj tso kua mis loj loj txog li 1,800 kg - tab sis xav tau kev tswj xyuas nruj kom tsis txhob muaj qhov tsis xws luag hauv cov phab ntsa nyias nyias. Kev nqis peev casting muab ± 0.05 hli qhov ntev rov ua dua rau AMS 5387 cobalt alloy plugs-tab sis yuav tsum muaj cov qauv siv nyiaj txiag nthuav dav. Peb tsis xaiv ib qho txheej txheem thiab yuam kom haum txhua qhov chaw. Hloov chaw, peb daim ntawv qhia txhua qhov tiv thaiv peb cov qauv: phab ntsa thickness piv, qhov yuav tsum tau ua kom tiav (Ra ≤ 1.6 µm vs. Ra ≤ 6.3 µm), thiab kev ua haujlwm thauj khoom. Piv txwv li, lub hydraulic siab valve lub cev siv cov xuab zeb casting rau nws lub plhaub sab nraud - tab sis cov dej ntws sab hauv yog CNC-machined post-cam khwb cia los tuav GD&T kam rau ua nruj dua ± 0.025 hli. Txoj kev hybrid ntawd tsis yog xaiv tau. Nws yog qhov koj ua tau raws li ISO 8502-3 kev huv huv specs * thiab * ASME B16.34 siab ntsuas.
Dimensional Stability pib ua ntej pwm yog nchuav
Peb ib zaug tau txais ib daim duab rau lub piston twj tso kua mis vaj tse nrog 12 qhov tseem ceeb bores - tag nrho cov teev rau ± 0.015 hli. Cov neeg siv khoom xav tau cast-to-finish machining. Tab sis thermal contraction nyob rau hauv ductile hlau txawv los ntawm seem thickness. Lub phab ntsa 45-mm shrinks 0.28% ntau tshaj li 22-mm tav. Yog li peb tsim cov nyiaj qis qis rau hauv cov qauv cuab yeej-tsis yog qhov kev sib tw ruaj khov, tab sis raws li cov kab nkhaus parametric khi rau lub sijhawm solidification hauv zos (xws li MAGMAsoft simulation). Tom qab ntawd peb tau txheeb xyuas tus cwj pwm qis nrog kev sim ntsuas kev txi, ntsuas ntawm Zeiss PRISMO CMM. Tsuas yog tom qab ntawd peb tau pom zoo rau kev tsim khoom. Qhov no yog vim li cas peb cov txheej txheem kev soj ntsuam suav nrog 100% kev ntsuas kev sib koom ua ke ntawm peb theem: ua-cam khwb cia, tom qab kev ntxhov siab, thiab kev ua haujlwm tom qab. Traceability tsis yog ib daim ntawv qhia-nws yog laser-etched serial tooj txuas txhua feem rau nws cov cav yaj, kho cua sov nkhaus, thiab CMM daim ntawv qhia kawg.
Kev Tswjhwm Zoo yog tsim rau hauv txhua kauj ruam ua haujlwm
Qee lub Hoobkas kho QC ua lub rooj vag thaum kawg. Peb embed nws qhov twg tsis ua hauj lwm tshwm sim: raw khoom txais, pwm los ua ke, pouring kub xyuas, shakeout sij hawm, thiab pre-heat-kho hardness checks. Peb cov neeg soj ntsuam siv cov phom PMI portable kom paub meej tias qib alloy ua ntej casting-thiab kuaj ultrasonic (ASTM E114) ntawm txhua qhov tuab-section steel casting saum 75 hli. Rau cov khoom siv cobalt-nickel, peb ntxiv fluorescent penetrant tshuaj xyuas (ASTM E1417) vim tias micro-cracks nkaum hauv thaj tsam dendritic. Thiab yog - peb khaws tag nrho cov ntaub ntawv digitally rau 15 xyoo. Tsis yog vim hais tias tus qauv hais li ntawd, tab sis vim tias thaum European OEM taug qab qhov chaw tsis ua haujlwm rau ib pawg ntawm AMS 5387, peb rub tag nrho cov kev tshuaj xyuas keeb kwm hauv 83 vib nas this. Tsis muaj kwv yees. Tsis ncua.
Cov cov hauv paus ntsiab lus ntawm hlau casting Hoobkas Kev vam meej boil mus rau peb yam uas tsis muaj kev sib tham: kev qhuab qhia metallurgical, cov txheej txheem tshwj xeeb ntawm kev pom, thiab kev soj ntsuam nruj rau hauv kev ua haujlwm-tsis bolted thaum kawg. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., cov ntsiab lus no tsis yog txoj kev xav. Lawv yog li cas peb xa lub siab li qub uas ua haujlwm ntawm 450 ° C yam tsis muaj qhov xau, lub twj tso kua mis uas muaj kev sib koom ua ke tom qab 2 lab lub voj voog, thiab cobalt alloy nozzles uas tiv thaiv kev yaig hauv cov twj slurry abrasive. Raws li casting-machining hybrid complexity nce - thiab cov qauv zoo li NORSOK M-650 thiab API 6A nruj - cov hauv paus ntsiab lus tsis hloov. Lawv tsuas yog thov kom ua tiav qhov tob. Qhov ntawd yog qhov kev paub ntsib engineering.
