Thaum muab khoom Co T400 Hoobkas cov neeg koom tes rau kev txiav txim ntau ntawm cov khoom siv cobalt-raws li kev ua haujlwm siab, cov kws ua haujlwm thiab cov neeg saib xyuas kev yuav khoom ntsib qhov chaw nqaim-thiab kev kawm nkhaus. Peb tau pom cov neeg siv khoom xaj AMS 5387 twj tso kua mis los ntawm peb tus neeg muag khoom sib txawv tsuas yog tsis lees txais ob qhov kev xa khoom vim qhov tsis sib xws ntawm microstructural inconsistency nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam. Lwm tus tau ncua tag nrho cov kev sib koom ua ke ntawm hydraulic tos rau kev rov ua haujlwm ntawm T800 alloy nozzles uas ua tsis tau zoo rau kev caij tsheb kauj vab ntawm 320 bar. Cov no tsis yog rooj plaub ntug. Lawv yog cov tsos mob ntawm qhov sib sib zog nqus tsis sib haum: feem ntau cov neeg muab khoom hlau kho Co T400 tsuas yog lwm qhov "exotic alloy" - tsis yog cov khoom xav tau kev qhuab qhia metallurgical, thermal keeb kwm tswj, thiab kev ua haujlwm zoo ntawm txhua theem.
Vim li cas Co T400 Xav Tau Ntau Tshaj Li Txheej Txheem Machining Peev Xwm
Co T400 tsis yog qib generic-nws yog cobalt-nickel-chromium-molybdenum superalloy engineered rau kev tiv thaiv rau galling, yaig, thiab thermal qaug zog nyob rau hauv lub siab-siab, high-temperature kev pab cuam. Nws hardness (38-45 HRC), tsis tshua muaj thermal expansion, thiab tshwj xeeb corrosion kuj ua rau nws zoo tagnrho rau lub twj tso kua mis tseem ceeb, lub rooj zaum valve, thiab hnav lub tes tsho. Tab sis cov khoom qub no kuj ua rau nws tsis yooj yim rau lub tshuab: cov cuab yeej hnav nrawm 3-5 × sai dua nrog 316 stainless hlau; residual kev ntxhov siab tuaj yeem cuam tshuam cov vaj tse nyias-walled thaum kawg ua tiav; thiab kev kho cua sov tsis zoo erodes cov carbide dispersion heev uas xa cov hnav tsis kam. Yog vim li cas "CNC muaj peev xwm" tsis txaus. Koj xav tau ib tus neeg koom tes uas kho txhua qhov Co T400 zoo li lub luag haujlwm tseem ceeb-tsis yog khoom muag.
Vertical Integration daws cov ntsiab lus mob ntau lawm
Peb tau taug qab ntau dua 60 Co T400 xaj xa khoom hauv 18 lub hlis dhau los rau North American oilfield khoom OEMs. Cov khoom xa tuaj raws sij hawm, nrog xoom qhov tsis lees paub, sib koom ib qho zoo: kev ua tswv cuab tag nrho - los ntawm cov ntawv pov thawj raw cov ntaub ntawv los ntawm kev casting, rough machining, tov annealing, precision finish machining, thiab zaum kawg kev ua haujlwm. Qhov ntawd tsis yog theoretical. Nws txhais tau tias:
- Cov ntaub ntawv traceability mus rau lub melt batch, txheeb xyuas ASTM F962 thiab AMS 5754 rau cov tshuaj muaj pes tsawg leeg thiab cov nplej loj
- Hauv-tus txheej txheem CMM tshuaj xyuas tom qab txhua qhov haujlwm tseem ceeb, tsis yog qhov kev kuaj zaum kawg nkaus xwb - ntes cov thermal distortion ua ntej nyuaj tig
- Kev kho cua sov tau ua hauv tsev, nrog rau cov cav ntoo rauv khi ncaj qha rau feem ntau tus lej thiab siv tau raws li AMS 2750E
- Tsis muaj kev sib koom tes ntawm cov chaw tsim khoom, lub khw muag khoom, thiab cov neeg muag khoom kub-kho- tshem tawm cov kev sib txuas lus tsis zoo ntawm lub voj voog tempering lossis cua txias
Qhov no tsis yog hais txog kev yooj yim. Nws yog hais txog kev tiv thaiv $ 12,000 tus nqi rov ua haujlwm peb pom ntawm cov txheej txheem piston twj tso kua mis lub tog raj kheej - tsis lees paub vim tias tus neeg muag khoom sab nraud cov khoom siv hluav taws xob siv hluav taws xob tau siv 15 ° C siab dua qhov sov so, degrading intergranular corrosion kuj.
Engineering Partnership pib ua ntej thawj daim duab kos npe
Qee cov neeg muag khoom tos kom tiav GD&T ua ntej hais. Qhov ntawd lig dhau lawm. Hauv kev xa tawm tiag tiag hauv ntiaj teb, Co T400 qhov tsis ua tiav tsis yog los ntawm kev tsim khoom yuam kev - tab sis los ntawm kev saib xyuas kev tsim: ntse sab hauv cov ces kaum ua rau muaj kev ntxhov siab, lub kaum sab xis tsis txaus ua rau muaj qhov tsis xws luag, lossis qhov chaw tiav tsis hais txog kev ua haujlwm sealing. Ntawm peb qhov chaw, kev tshuaj xyuas engineering pib lub sijhawm koj qhia txog lub tswvyim kos duab. Peb chij manufacturability pheej hmoo ntxov-xws li pom zoo kom hloov lub vojvoog fillet kom tsis txhob tawg thaum lub sij hawm kev daws annealing, los yog hloov lub machined-thiab-brazed los ua ke rau ib tug ib-thooj casting qhov twg phab ntsa thickness variation ntau tshaj 25%. Qhov no tsis yog kev tawm tswv yim fluff. Nws yog raws li cov ntaub ntawv tsis ua hauj lwm tsom xam los ntawm 127 teb rov qab hla hydraulic, marine, thiab geothermal daim ntaub ntawv.
Kev ntseeg tsis tau cog lus tseg—Nws tau ntsuas, taug qab, thiab xa
"Txhim khu kev txiav txim ntau" txhais tau hais tias kev xa khoom tuaj yeem * thiab * kev ua tau zoo. Peb lav ob qho tib si los ntawm kev ua kom zoo rau hauv kev ua haujlwm-tsis tacking nws thaum kawg. Txhua Co T400 feem cuam tshuam:
- Cov ntaub ntawv pov thawj raw khoom siv OES spectroscopy thiab ntawv pov thawj zeb xeem ntawv ceeb toom
- Kev tshuaj xyuas tsis zoo (dye penetrant + ultrasonic) post-casting thiab post-machining
- Dimensional validation ntawm Zeiss CONTURA G2 CMM nrog ISO 10360-2 certified raug
- Kev sim ua haujlwm - suav nrog hydrostatic siab tuav ntawm 1.5 × ua haujlwm siab rau 30 feeb - qhov twg tau teev tseg
Thiab yog - peb khaws tag nrho traceability: tus xov tooj cua sov, machining program version, tus neeg teb xov tooj ID, lub sij hawm soj ntsuam, thiab calibration cov ntaub ntawv rau tag nrho cov khoom ntsuas. Tsis yog vim cov neeg soj ntsuam xav tau nws. Vim hais tias thaum lub winch center ncej cov menyuam ua tsis tau tejyam nyob rau hauv ib tug tej thaj chaw deb mining site, koj pab neeg xav tau cov lus teb - tsis zam txim.
Rau cov neeg yuav khoom ntsuas a Co T400 Hoobkas rau lub sijhawm ntev, cov khoom lag luam siab, cov lus nug tsis yog "Lawv puas tuaj yeem ua tau?" Nws yog "Lawv puas nkag siab tias yuav ua li cas rau Co T400 thaum koj thawb nws dhau cov ntaub ntawv txwv-thiab lawv yuav ua pov thawj tias nws yuav tsis poob hauv koj daim ntawv thov?" Qhov kev lav phib xaub ntawd tsis yog los ntawm daim ntawv qhia lossis ntawv pov thawj nkaus xwb. Nws los ntawm kev ua haujlwm hnyav-batch tom qab batch-hauv khw hauv pem teb, hauv chav kuaj, thiab hauv thaj teb. Qhov ntawd yog tus qauv peb ntsib. Txhua lub sijhawm.
