Thaum engineers qhia a poob ciab casting qhov chaw Hoobkas, lawv tsis yog tsuas yog xaj hlau - lawv xav tau qhov ntev ntawm qhov rov ua dua hauv qab 0.02 hli, microstructural sib xws thoob plaws 100-kg cobalt alloy twj tso kua mis, thiab xoom kam rau qhov porosity hauv siab siab valve lub cev. Peb tau pom cov neeg siv khoom xa rov qab peb zaug ntawm AMS 5387 nozzles - tsuas yog txhawm rau tshawb pom lub hauv paus ua rau tsis yog kev ua haujlwm, tab sis tsis sib haum xeeb ua ntej-cast grain qauv los ntawm qhov chaw tsim khoom. Tias yog vim li cas precision peev casting tsis yog hais txog "tsuas yog ua pwm." Nws yog hais txog kev tswj hwm txhua qhov sib txawv: ciab qauv shrinkage tus nqi, ceramic plhaub permeability, dewaxing ramp ceev, nqus-pab ncuav lub sij hawm, thiab tom qab-cam khwb cia cua sov kho kom sov uniformity.
Vim li cas Poob Wax Casting Tseem Yeej rau Lub Hom Phiaj-Critical Industrial Parts
Poob ciab casting-tseem hu ua peev casting-xa net-shape complexity tsis muaj xuab zeb casting lossis forging tuaj yeem sib phim. Tab sis tsis yog tag nrho cov factories ua nws kev ntseeg siab ntawm kev lag luam. Qhov sib txawv yog nyob rau hauv cov txheej txheem kev qhuab qhia, tsis yog cov cuab yeej siv xwb. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho txhua tus cobalt-nickel tivthaiv zoo li nws yuav tswj 350-bar hydraulic txaus nyob rau hauv ib qho offshore drilling rig. Qhov ntawd txhais tau tias tag nrho traceability los ntawm T800 alloy billet ntawv pov thawj (ASTM B575) los ntawm lub plhaub firing curves logged ib batch. Peb tau ntsuas txog li 12% qhov dav dav hauv lub tog raj kheej vaj tsev thaum dewaxing kub hloov pauv los ntawm ± 5 ° C - yog li peb tam sim no tswj nws hauv ± 1.5 ° C. Cov neeg siv khoom uas hla cov khoom siv taug qab feem ntau pom cov kab nrib pleb tshwm sim tom qab 4,200 teev ua haujlwm - tsis yog thaum kuaj kev tsim nyog.
Qhov twg Feem ntau Factories Fail — thiab Yuav ua li cas Vertical Integration kho nws
Qee tus neeg muag khoom tawm ntawm qhov chaw casting, machining, thiab ua tiav rau cov neeg muag khoom sib cais. Qhov ntawd ua rau peb lub ntsiab lus tsis ua haujlwm: tsis sib haum GD&T kev txhais lus ntawm cov chaw tsim khoom thiab CNC lub khw, qhov chaw ua tiav qhov tsis sib xws uas npog qhov tsis xws luag hauv qab, thiab thermal distortion thaum kho cua sov vim tsis muaj kev sib koom ua ke. QINGDAO QIANGSENYUAN TECHNOLOGY muaj tag nrho cov saw-los ntawm kev npaj lub plhaub ceramic mus rau ntau lub axis milling ntawm cov hniav hauv cov hniav hauv piston twj tso kua mis. Thaum tus neeg siv khoom nyob sab Europe xav tau qhov tsis yog tus qauv winch center ncej cov menyuam nrog 0.015-mm roundness kam rau ua ntawm 320-mm OD, peb zam qhov raug 3-lub lis piam rov qab los ntawm kev khiav thawj kab lus CMM scans * ua ntej * kawg lub plhaub burnout. Qhov tshwm sim: thawj-khiav hla tus nqi dhia los ntawm 68% mus rau 97%. Key enablers? Nyob rau hauv tsev kho qhov muag sib piv rau cov qauv siv quav ciab pov thawj, ISO 17025-kev lees paub qhov kev kuaj tawv tawv, thiab lub sijhawm ntsuas thermal ntawm lub sijhawm thaum cov tshuaj annealing.
Yam Koj Yuav Tau Txais - Tsis Yog Dab Tsi Yog Dab Tsi
Nug ib tus neeg saib xyuas kev yuav khoom: "tso ntawv pov thawj" tsis txhais hais tias "tso pov thawj." QINGDAO QIANGSENYUAN TECHNOLOGY muab cov ntaub ntawv qhia txog cov khoom siv tag nrho (MTRs) nrog rau txhua qhov khoom xa tuaj - suav nrog lub zog tensile, yield, elongation, thiab cuam tshuam qhov tseem ceeb ntawm ASTM A957 rau castings thiab ASTM E8 rau machined qauv. Rau cobalt alloy nozzles, peb tshaj tawm carbide faib ntawm SEM-EDS daim ntawv qhia - tsis yog bulk chemistry. Peb tsis tsuas yog ntsib AMS 5387; peb validate carbide morphology tiv thaiv AMS 2269. Nto tiav? Ra 0.4 µm tsis txaus yog qhov siab tshaj plaws-rau-lub hav siab tshaj 3.2 µm - yog li peb ntsuas ob qho tib si. Thiab yog, peb khaws cov ntaub ntawv pov thawj raw khoom rau xya xyoo, tsis yog ob. Qhov no tsis yog overkill. Nws yog li cas peb tiv thaiv ib qho kev ua tsis tau zoo los ntawm kev tso tseg $ 2.3 lab engineering tsheb sib dhos kab nyob rau sab hnub tuaj Asia.
Koj cov kauj ruam tom ntej tsis yog "Tau Txais Cov Lus Qhia" - Nws yog "Ua Haujlwm Zoo"
Ua ntej xa cov duab kos, nug koj li poob ciab casting qhov chaw Hoobkas peb lo lus nug: Koj puas tuaj yeem qhia peb lub hli dhau los Cpk cov ntaub ntawv rau cov kab loj loj ntawm cov khoom cobalt zoo sib xws? Koj puas ua ntsuas ultrasonic ntawm txhua qhov ntau dua 15 kg? Puas yog koj lub plhaub binder system tau ntawv pov thawj rau aerospace-qib qis-tshauv seem? Yog tias cov lus teb tsis meej-lossis phem dua, "peb ua raws li kev coj ua" - taug kev deb. Precision tsis txhais los ntawm kev lag luam daim ntawv qhia. Nws tau raug pov thawj nyob rau hauv cov qauv ntawm cov ntoo khaub lig-sectioned AMS 5387 twj tso kua mis vaj tse, nyob rau hauv lub repeatability ntawm 0.008-mm phab ntsa thicknesses thoob plaws 12 kab noj hniav, thiab nyob rau hauv tsis muaj rework ntawm functional nto. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsim kom muaj kev ntseeg siab rau txhua theem - tsis yog ib qho ntxiv, tab sis raws li kev ua haujlwm. Tus qauv tom ntej koj pom zoo yuav tsis tsuas yog ua tau raws li spec. Nws yuav muaj sia nyob 15,000 lub voj voog ntawm 220 ° C yam tsis muaj microcrack pib. Qhov ntawd tsis yog optimism. Nws yog dab tsi tshwm sim thaum metallurgy, metrology, thiab kev tsim khoom hais tib yam lus.
