Thaum cov kws tshaj lij qhia cov hlau tsis xeb hlau qhov chaw pib, lawv tsis yog xaiv cov khoom siv xwb - lawv tau cog lus rau qhov kev ruaj ntseg nyob rau hauv thermal cycling, corrosion kuj nyob rau hauv aggressive fluids, thiab structural integrity ntawm 300+ bar kev khiav hauj lwm siab. Tias yog vim li cas kev tsim khoom los ntawm a stainless hlau casting pib qhov chaw Hoobkas nrog pov thawj metallurgical kev qhuab qhia - tsis yog lub peev xwm nrhiav tau - ua rau qhov sib txawv ntawm kev ua haujlwm tsis ua haujlwm thiab 15 xyoo kev pabcuam lub neej.
Vim li cas "Casting" Ib leeg tsis txaus-Tshwj xeeb rau Automotive-Qib Precision
Peb tau pom ntau txoj haujlwm kaw thaum castings dhau qhov kev kuaj pom tab sis ua tsis tiav kev sim siab ntawm kev sib dhos zaum kawg. Lub hauv paus ua rau? Cov qauv ntawm cov nplej tsis sib xws los ntawm kev tswj tsis tau zoo, lossis cov kev ntxhov siab seem uas tsis tau tso tseg ua ntej machining. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua qhov stainless hlau casting pib nrog AMS 5387-raws li raw khoom - traceable rau cua sov tooj, ntawv pov thawj rau tensile zog ≥860 MPa thiab elongation ≥12% nyob rau hauv lub as-cam khwb cia + tov-annealed mob. Tsis muaj batch hloov. Tsis muaj tus neeg muag khoom luv luv. Peb co-validate melt chemistry nrog peb cov khoom koom tes ua ntej pouring pib.
Peb cov txheej txheem xuab zeb siv cov txheej txheem ceramic-coated rau saum npoo tiav Ra ≤6.3 μm-nruj txaus kom hla kev ua haujlwm tsis zoo ntawm lub ntsej muag tsis tseem ceeb. Rau cov geometries nyuaj xws li piston twj tso kua mis lub tog raj kheej vaj tse, peb muab peev casting rau nyias-phab ntsa seem (phab ntsa thickness mus rau 4.5 hli) nrog precision CNC tig thiab sab hauv sib tsoo-tag nrho nyob rau hauv ib qho chaw. Qhov kev sib koom ua ke ntsug no tshem tawm kev sib tshuam ntawm qhov chaw seem. Ib tus neeg siv khoom hauv lub tebchaws Yelemes tsis ntev los no tau tshaj tawm 99.8% thawj-dhau tawm los ntawm 12-thooj hydraulic manifold sib dhos-vim lub flange ntsej muag flatness (0.015 hli max sib txawv) thiab qhov chaw nres nkoj xov concentricity (0.02 hli TIR) tau tuav hla ob qho tib si casting thiab tiav theem.
Qhov twg Feem ntau Factories txiav kaum-thiab Yuav ua li cas peb zam lawv
Qee cov tuam ntxhab kho stainless hlau casting raws li cov txheej txheem khoom. Lawv nchuav, co tawm, tshuab, thiab nkoj. Tab sis kev ua haujlwm siab ntawm cov khoom siv pib xav tau ntau dua: tswj cov cua txias kom tiv thaiv kev tsim cov theem ntawm sigma hauv 316SS; kev ntxhov siab-relief annealing * ua ntej * zaum kawg machining rau xauv hauv geometry; thiab CMM-raws li GD&T validation ntawm txhua qhov ntau - tsis yog thawj cov qauv qauv.
Peb khiav peb qhov yuav tsum tau kuaj xyuas:
- Cov ntaub ntawv pov thawj los ntawm OES spectrometry thiab tensile bar kuaj
- Kev soj ntsuam hauv kev ua haujlwm tom qab siv lub tshuab ua haujlwm tsis zoo siv Zeiss CONTURA G2 CMMs-nrog rau tag nrho ASME Y14.5-raws li cov lus ceeb toom rau txoj hauj lwm, profile, thiab runout
- Kev sim ua haujlwm kawg: hydrostatic siab tuav ntawm 1.5 × ntsuas kev ua haujlwm siab rau 30 feeb, ntxiv rau dye-penetrant tshuaj xyuas ib ASTM E165
Qhov no tsis yog overkill - nws yog li cas peb lav tias lub winch center ncej cov menyuam rau lub tsheb tawm ntawm txoj kev loj muaj sia nyob 20,000 cycles ntawm 12-tuj dynamic loading yam tsis muaj microcrack pib.
Lub Ntiaj Teb Kev Ua Haujlwm tiag tiag xav tau peb lub peev xwm
Peb stainless hlau casting qhov chaw pib ua haujlwm rau ib puag ncig uas tsis ua haujlwm txhais tau tias lub sijhawm poob nqi $ 18,000 / teev. Yog li peb engineer rau qhov xwm txheej phem tshaj plaws - tsis yog cov ntaub ntawv nruab nrab. Piv txwv li:
- Siab li qub rau high-pressure common-rail diesel systems undergo thermal shock cycling los ntawm -40 ° C rau + 180 ° C - validated nrog 500 cycles ua ntej xa
- Lub hauv paus twj tso kua mis rau seawater desalination units raug kuaj rau pitting tsis kam ntawm ASTM G48 Txoj Kev A (6% FeCl₃, 24 teev, tsis muaj qhov tob> 0.05 hli)
- Tag nrho T800 cobalt-based alloy castings suav nrog kev tshuaj xyuas microstructure ntawm SEM / EDS kom paub meej tias cov carbide dispersion tsis sib xws - tseem ceeb rau kev hnav tsis kam hauv slurry twj impellers
Peb tsis tsuas yog ua tau raws li ISO 9001. Peb ua raws txhua kauj ruam cov txheej txheem nrog SAE AS9100 cov hauv paus ntsiab lus-txawm tias peb tsis muaj ntawv pov thawj hauv aerospace-vim tias kev hloov pauv ncaj qha mus rau lub tsheb muaj kev ntseeg siab.
Xaiv tus khub zoo txhais tau tias nug cov lus nug zoo
Yog tias koj ntsuas a stainless hlau casting pib qhov chaw Hoobkas, nug peb yam no ua ntej kos npe rau PO:
- Koj puas tuaj yeem muab tag nrho cov ntaub ntawv taug qab-los ntawm tus lej xov tooj cua sov mus rau daim ntawv xeem kawg-rau lub hli tas los cov khoom xa tuaj?
- Koj puas ua qhov kev ntxhov siab-relief annealing * ua ntej * zaum kawg machining? Yog tias tsis yog, koj yuav them nyiaj li cas rau kev cuam tshuam?
- Dab tsi yog koj qhov kev ua haujlwm ntev tshaj plaws? Qhia kuv cov ntaub ntawv Cpk rau qhov loj me ntawm rau lub hlis.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. luam tawm cov ntaub ntawv no proactively thaum lub sij hawm engineering tshuaj xyuas. Peb paub tias kev ntseeg tsis yog tsim los ntawm daim ntawv qhia - nws tau txais los ntawm kev pom tseeb ntawm qhov ntsuas, nws ntsuas li cas, thiab yuav ua li cas thaum qhov kev ntsuas poob rau sab nraud. Peb lub sijhawm ua haujlwm rau nruab nrab-ntev xaj (50-500 pcs) yog 14 lub lis piam - tsis yog vim peb qeeb, tab sis vim tias peb tsim hauv tsis rau kev siv lub tshuab metallurgical, tsis yog lub sijhawm siv tshuab xwb.
Stainless hlau casting tsheb qhov chaw tsis hloov pauv. Lawv yog cov pab pawg neeg. Thiab ua kom muaj kev ua tau zoo pib ntev ua ntej cov pwm tau nchuav - nrog rau cov khoom siv science, txheej txheem kev qhuab qhia, thiab xoom kam rau ua qhov kev xav. Qhov ntawd yog tus qauv peb tuav - tsis yog rau peb cov neeg siv khoom tshwj xeeb, tab sis rau cov tshuab lawv cov khoom yuav muaj zog tag kis.
