Thaum cov kws ua haujlwm qhia cov hlau tsis muaj hlau tsis muaj cov khoom siv pov tseg rau cov hydraulic li qub lossis cov twj tso kua mis siab, lawv tsis yog xaj hlau xwb - lawv xav tau qhov kev ruaj ntseg, microstructural kev ncaj ncees, thiab corrosion kuj nyob rau hauv lub ntiaj teb kev ntxhov siab. Yog vim li cas thiaj li muaj coob zuj zus tuaj ntawm North American thiab European OEMs tam sim no taug qab cov khoom tseem ceeb rov qab mus rau ib qhov chaw hauv Qingdao: cov hlau tsis muaj steel poob wax casting qhov chaw Hoobkas tsim tsis nyob ib puag ncig ntim, tab sis nyob ib ncig ntawm kev qhuab qhia metallurgical.
Vim li cas Kev nqis peev Casting tseem yeej rau Complex Stainless Hlau Geometry
Poob ciab casting-kev nqis peev casting-tseem unmatched rau stainless hlau qhov chaw nrog nyias phab ntsa, sab hauv, nruj tolerances (± 0.05 hli raug), thiab xoom daim ntawv yuav tsum tau. CNC machining ib leeg tsis tuaj yeem ncav cuag sab hauv contours ntawm lub piston twj tso kua mis lub tog raj kheej vaj tse yam tsis muaj ntau yam teeb tsa, cov cuab yeej cuam tshuam, lossis cov khoom pov tseg ntau tshaj 70%. Xuab zeb casting tsis muaj qhov chaw tiav (<3.2 µm Ra) thiab cov nplej sib xws uas xav tau rau kev siv qaug zog-tseem ceeb. Kev nqis peev casting txuas hniav uas sib txawv-tab sis tsuas yog tias lub tuam txhab tswj hwm tag nrho cov saw hlau: siv quav ciab qauv precision, ceramic plhaub formulation, tswj dewaxing, nqus-pab pouring, thiab tom qab cam khwb cia cua sov kho raws li ASTM A487 los yog AMS 5659.
Peb tau pom cov neeg siv khoom hloov los ntawm cov xuab zeb-cam khwb cia 316 vaj tse rau peev-cam khwb cia F316L tom qab rov ua dua ntawm cov pob qij txha. Lub hauv paus ua rau? Inconsistent interdendritic segregation nyob rau hauv xuab zeb castings. Peb cov txheej txheem siv cov ntawv pov thawj, lub tshuab nqus-melted ingots-traceable rau cua sov tooj-thiab tuav tus nqi solidification nyob rau hauv ± 5% nyob rau hauv 120 kg batch. Tsis muaj "zoo txaus" chemistry. Txhua lub ncuav muaj xws li spectrographic pov thawj ua ntej lub plhaub firing.
Plaub Tsis Muaj Peev Xwm Sib Tham Koj Tsis tuaj yeem Outsource
Qhov tseeb stainless hlau poob ciab casting qhov chaw Hoobkas yuav tsum muaj plaub txoj haujlwm no - tsis yog daim ntawv cog lus rau lawv:
- Cov khoom siv raw khoom tswj xyuas: Peb qhov chaw ncaj qha los ntawm cov zeb nrog EN 10204 3.1 ntawv pov thawj. Tsis muaj broker-sourced billets. Rau F22, F28, lossis cov qib kev cai duplex, peb siv tau cov ntsiab lus ferrite ua ntej nchuav siv cov hlau nplaum induction probes-tsis yog tom qab-kub-kho cov ntawv qhia.
- CMM-integrated dimension tswj: Txhua qhov ntau dhau qhov kev lees paub GD&T tag nrho ntawm Zeiss Contura G2 RDS. Cov ntaub ntawv tseem ceeb-xws li lub rooj zaum lub rooj sib txig sib luag lossis cov ntawv sau cov ntawv sau tawm-yog ntsuas * ua ntej * kev kho cua sov, tom qab ntawd rov xyuas dua tom qab kev ntxhov siab. Peb chij drift> 0.015 hli tam sim ntawd.
- Hybrid finishing muaj peev xwm: Cam khwb cia hlau tsis yog qhov kawg. Peb tshuab sealing ntsej muag rau Ra 0.8 µm, siv electropolishing ib ASTM B912, thiab ua helium leak kuaj ntawm 10⁻⁹ mbar·L / s rau siab li qub. Tsis muaj tes polished "cosmetic" tiav - peb ntsuas kev ua haujlwm du.
- Failure-mode-paub engineering tshuaj xyuas: Thaum tus neeg siv khoom xa daim duab rau AMS 5387 cobalt alloy nozzle, peb tsis yog hais lus xwb. Peb xyuas cov phab ntsa thickness hloov pauv, txheeb xyuas qhov muaj peev xwm kub ntawm cov ntoo wax layout, thiab qhia txog kev hloov pauv ntawm lub voj voog uas tiv thaiv microporosity-raws li 147 ua ntej tsim ntawm cov geometries zoo sib xws.
Dab tsi Cov Neeg Siv Khoom Ntsuas tiag tiag—tsis yog yam lawv qhia
Spec sheets teev lub zog tensile thiab hardness. Kev lees paub tiag tiag hauv ntiaj teb sim ib yam dab tsi ntxiv: rov ua dua hla lub voj voog thermal. Ib lub tuam txhab European twj tso kua mis tau khiav 500-teev kev sim siab ntawm peb F304L winch center ncej chais. Lawv taug qab radial runout sib txawv tom qab txhua 100 teev ntawm 120 ° C thiab 35 MPa load. Qhov tshwm sim? Qhov kev hloov pauv tau nyob qis dua 0.008 mm - nyob rau hauv ib nrab ntawm qhov pib kam rau ua. Vim li cas? Vim tias peb cov casting-rau-machining sequence locks nyob rau hauv residual kev nyuaj siab thaum ntxov: tov anneal → ntxhib CNC → laus → tiav grind. Tsis yog lwm txoj hauv kev.
Qhov ntawd yog qhov sib txawv ntawm tus neeg xa khoom uas thauj khoom thiab tus neeg xa khoom ua haujlwm. Peb teev txhua lub voj voog kho cua sov, txhua CMM daim ntawv tshaj tawm, txhua qhov kev soj ntsuam ultrasonic - tsis yog rau kev ua raws li cov ntaub ntawv, tab sis yog li thaum ib feem tsis ua haujlwm, peb rov tsim nws tag nrho cov thermal thiab mechanical keeb kwm hauv qab 90 feeb.
Xaiv koj tus khub tsis yog hais txog Geography-Nws yog hais txog Traceability qhov tob
Yog lawm, Qingdao muab cov txiaj ntsig zoo rau kev xa khoom hauv Asia-Pacific. Tab sis dab tsi tseem ceeb thoob ntiaj teb yog seb koj cov hlau tsis muaj hlau tsis ploj los ntawm cov khoom siv hluav taws xob tuaj yeem ua pov thawj - nqes mus rau daim ntawv pov thawj zeb thiab lub cav cav - yog vim li cas cov khoom tshwj xeeb tau ntsib ASTM A743 Qib CF8M es tsis txhob poob qis los ntawm 0.3% Mo. Nws yog seb lawv pab pawg R & D tau tshaj tawm cov ntaub ntawv tshawb fawb txog kev txo qis porosity hauv T800 alloy impeller vanes (peb muaj).
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm li no vim tias nws cov engineers tau siv ntau xyoo los kho cov twj tso kua mis ua tsis tiav hauv cov khoom siv sab nrauv-tsis sau cov specs hauv boardrooms. Lawv qhov chaw tsis yog "ISO-certified" raws li daim paib; Nws tau teeb tsa kom txhua tus neeg ua haujlwm paub yuav ua li cas qhov sib txawv ntawm 2 ° C nyob rau hauv lub plhaub kub hnyiab cuam tshuam rau cov khoom khaws cia hauv 17-4PH.
Yog hais tias koj xav tau stainless hlau poob ciab casting qhov chaw uas muaj sia nyob qhov twg lwm tus qaug zog, corrode, los yog xau - pib nrog traceability. Ces thov pov thawj. Tom qab ntawd txheeb xyuas koj tus kheej. Qhov ntawd yog li cas lub luag haujlwm tseem ceeb ntawm cov khoom tau txais lawv qhov chaw - tsis yog ntawm lub txee, tab sis hauv kev pabcuam.
