Kev nqis peev casting stainless hlau muab net-puab precision qhov chaw uas tsoos machining hits txwv-tshwj xeeb tshaj yog rau complex geometries, nyias phab ntsa, los yog sab hauv passages nyob rau hauv hydraulic li qub, twj tso kua mis vaj tse, thiab oilfield Cheebtsam. Peb tau nrum ntau dua 2,400 qhov tshwj xeeb stainless hlau nyob rau hauv 18 lub hlis dhau los ib leeg-thiab txhua tus yuav tsum nruj dua ± 0.05 hli qhov ntev tswj, tag nrho microstructure traceability, thiab xoom porosity nyob rau hauv lub siab-cov kabmob zones. Qhov ntawd tsis yog theoretical. Nws ua haujlwm txhua hnub hauv peb lub chaw tsim khoom ISO-certified hauv Qingdao.
Vim li cas peev casting stainless hlau ntaus lwm txoj hauv kev rau kev siv lub hom phiaj tseem ceeb
Ntau tus engineers default rau CNC-machined 316 los yog 17-4PH thaum lawv xav tau corrosion kuj thiab lub zog. Tab sis machining pib nrog cov khoom lag luam-khoom 60-85% ntawm cov khoom siv ntawm cov khoom xws li piston twj tso kua mis lub tog raj kheej vaj tse nrog concentric bores, radial ports, thiab asymmetrical flanges. Kev nqis peev casting stainless hlau tshem tawm cov khoom pov tseg thaum khaws cia cov khoom siv kho tshuab: tensile lub zog nyob qis dua ± 3% hla ib qho cua sov, cov nplej ntws ua raws li kev ua haujlwm thauj khoom, thiab qhov chaw tiav li-cam khwb cia ncav cuag Ra 3.2 µm-npaj rau sealing nto yam tsis muaj kev sib tsoo.
Peb tau pom cov neeg siv khoom hloov los ntawm xuab zeb casting mus rau peev casting stainless hlau tom qab rov ua tsis tiav hauv high-cycle hydraulic manifolds. Sand castings tawg ntawm fillets nyob rau hauv 35 MPa pulsation. Kev nqis peev castings dhau 500,000 lub voj voog ntawm 42 MPa-vim cov qauv siv quav ciab ntes radii mus rau 0.3 hli, tshem tawm cov kev ntxhov siab-ntsuas cov kaum ntse ntse. Qhov txawv tsis yog kom zoo nkauj xwb. Nws yog metallurgical kev ncaj ncees, txheeb xyuas raws li ASTM A743 / A744 thiab txhawb nqa los ntawm cov ntawv pov thawj kub tshwj xeeb.
Cov txiaj ntsig tseem ceeb tsis yog paub daws teeb meem - lawv ntsuas tau:
- Dimensional repeatability: CMM-tuaj yeem ua raws li 99.7% hla 12,000+ ntau lawm
- Kev siv cov khoom siv: 82% nruab nrab yield vs. 28% rau sib npaug machined qhov chaw
- Tsim kev ywj pheej: Tsis xav tau cov kaum sab xis; undercuts, qhov muag tsis pom qhov, thiab integrated mounting nta nrum ncaj qha
- Nto zoo: Tsis muaj kab sib cais, nyem, lossis hloov pauv tseem ceeb-tseem ceeb rau kev sib foob sib txuas
Tus nqi zais ntawm kev hla cov khoom siv thiab cov txheej txheem sib dhos
Qee tus xav tias qib stainless hlau ua haujlwm rau peev casting. Tsis yog. Peb tau muab pov tseg peb cov qauv cua sov ntawm 2205 duplex vim tias lub plhaub slurry tsis tuaj yeem tiv taus nws cov khoom hnyav dua. Qib tseem ceeb-tab sis ua li cas koj pov nws. 304 thiab 316 coj tus cwj pwm zoo hauv cov qauv silica-based shells. Tab sis superaustenitics zoo li AL-6XN thov ceramic-bonded zirconia shells thiab meej dewaxing ramp tus nqi. Cobalt-strengthened 317LMN? Yuav tsum tau nqus-pab pouring los suppress gas pitting.
Yog vim li cas peb koom tes tsim cov khoom specs nrog cov neeg muag khoom - tsis yog yuav "tso ntawv pov thawj" ingots. Thaum ib tus neeg siv khoom nyob sab Europe xav tau AMS 5387-raws li 6-tswj vaj tse, peb tau sim tsib cov khoom tawg tawm tsam thermal expansion curves, dendrite caj npab spacing, thiab interdendritic segregation maps. Tsuas yog ob leeg ua tau raws li qhov xav tau ntawm lub neej qaug zog ntawm 120 ° C. Tus so tau mus rau seem-tsis yog koj cov khoom muag, tsis yog koj lub sijhawm.
Qhov tshwm sim tiag tiag hauv ntiaj teb: Ib tus neeg Esxias sab hnub tuaj yeem txo qis qhov dej tsis ua haujlwm los ntawm 94% tom qab hloov los ntawm 316 peev castings rau peb cov tswj-cuam tshuam 316L nrog ≤12 ppm oxygen residual. Qhov kho tsis yog qhov tsim tshiab. Nws yog qhov tseeb metallurgy, ua tiav tas li.
Dab tsi ua rau tus neeg muag khoom muaj peev xwm tiag tiag - tsis yog ntawv pov thawj xwb
Cov ntawv pov thawj tseem ceeb - tab sis lawv tsis lav qhov ua tau zoo. Peb soj ntsuam txhua tus neeg muag khoom muaj peev xwm ntawm plaub qhov tsis sib tham:
- Raw khoom traceability: Tag nrho cov xov tooj cua sov nkag los ntawm ingot mus rau qhov kawg, nrog kev txheeb xyuas spectrographic ntawm kev tshuaj xyuas
- Nyob rau hauv cov txheej txheem metrology: CMM kuaj xyuas cov qauv siv quav ciab * thiab * lub plhaub sib dhos - tsis yog ua tiav castings
- Microstructure validation: Etched cross-sections tshuaj xyuas ib ASTM E112 rau grain loj, carbide faib, thiab delta ferrite cov ntsiab lus
- Kev kuaj ua haujlwm: Kev ntsuam xyuas siab lwj ntawm 1.5 × ua hauj lwm siab, nrog helium leak nrhiav kom tau mus txog 1 × 10⁻⁹ mbar·L / s
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. siv tag nrho plaub-tsis yog cov chaw kuaj xyuas, tab sis raws li kev tswj hwm kev teeb tsa. Thaum koj xaj kev nqis peev casting stainless hlau qhov chaw los ntawm peb, koj tau txais cov ntawv ceeb toom qhov ntev, cov ntsiab lus tsom xam, thiab cov duab microstructure - tsis yog daim ntawv pov thawj ntawm kev ua raws. Vim tias daim ntawv kos npe tsis txwv lub twj tso kua mis ntawm kev tawg thaum pib.
Cov kauj ruam tom ntej: Los ntawm kev kos duab mus rau kev xa khoom, tsis muaj kev xav tsis thoob
Yog tias koj qhov project tom ntej no suav nrog kev nqis peev casting stainless hlau rau kev kub siab, hnav siab, los yog tshuaj lom neeg ib puag ncig - pib nrog kev tshuaj xyuas kev tsim khoom. Xa koj pob GD&T. Peb mam li chij nta uas tsav tus nqi (xws li 0.1 hli phab ntsa ntu hauv 316) lossis kev pheej hmoo tsis lees paub (tsis tau hais meej saum npoo roughness ntawm cov av sib khi). Peb mam li qhia cov kev hloov pauv hlau uas txhim kho castability yam tsis muaj kev txi-xws li hloov ntawm 17-4PH rau 15-5PH kom zoo dua kub kua muag tsis kam nyob rau hauv nyias-section winch ncej rollers.
Tsis muaj kev ruaj ntseg. Tsis muaj ntawv muag khoom. Tsuas yog kev sib tham engineering hauv qhov ua haujlwm - thiab dab tsi ua tsis tau - hauv kev tsim khoom tiag. Koj yuav paub tsis pub dhau 72 teev seb koj tus qauv tsim puas yuav cam khwb cia, tshuab ntseeg tau, thiab ua haujlwm hauv qab. Qhov ceev ntawd los ntawm kev ua qhov no txhua hnub - tsis yog qee zaus.
Kev nqis peev casting stainless hlau tsis yog hais txog kev yooj yim. Nws yog hais txog kev daws teeb meem machining tsis tuaj yeem kov-tsis muaj kev lag luam tawm kev ntseeg siab. Qhov tseeb yog tsim nyob rau hauv. Qhov kev ntseeg tau txais - ib qho cua sov, ib qho ntau, ib qho kev sim siab ib zaug.
