Thaum cov kws tshaj lij qhia cov khoom siv hlau rau hydraulic manifolds, twj tso kua mis, lossis winch system shafts, lawv tsis tsuas yog xaj hlau - lawv tab tom twv ntawm qhov kev ruaj ntseg nyob rau hauv 300-bar siab, hnav tsis kam tom qab 10,000 cycles, thiab xoom batch-rau-batch variation hauv graphite nodule suav. Tias yog vim li cas muab los ntawm qhov tseeb cam khwb cia hlau ib feem Hoobkas tsis yog hais txog tus nqi qis tshaj. Nws yog hais txog metallurgical tswj, txheej txheem kev qhuab qhia, thiab engineering txuas ntxiv mus.
Vim li cas "Cast Iron" tsis yog ib qho khoom siv xwb
Peb tau pom ntau txoj haujlwm kaw vim tias kev yuav khoom kho "cam khwb cia hlau" ua cov khoom lag luam. Grey hlau (ASTM A48 Chav Kawm 30B) coj tsis muaj dab tsi zoo li cov hlau nplaum (ASTM A) thaum ua haujlwm ntawm 12,000 rpm - lossis thaum raug rau cov roj qaub condensate. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua qhov hlau casting pib nrog cov ntaub ntawv pov thawj raw khoom traceability: ladle tsom xam cov ntaub ntawv, thermal tsom xam curves, thiab microstructure pov thawj ntawm ISO 945-1. Tsis muaj kev zam. Yog hais tias koj lub piston twj tso kua mis vaj tse yuav tsum tau hom 3 graphite morphology nrog ≤2% dawb carbides, peb validate nws - tsis xav tias nws.
Qhov twg Sand Casting ntsib Precision Machining-tsis muaj kev cuam tshuam
Feem ntau cov chaw muag khoom outsource casting lossis machining. Qhov ntawd ua rau muaj qhov sib txawv ntawm qhov sib txawv: qhov tsis xws luag tsis tuaj yeem ua ntej CNC teeb tsa, cov tub ntxhais ua haujlwm tsis raug kho thaum lub sij hawm roughing, kev kho cua sov distortion tsis quav ntsej txog qhov kawg kev soj ntsuam. Peb khiav ob txoj hauv kev hauv ib lub ru tsev-ISO 9001-tsim xuab zeb casting kab noj ncaj qha rau hauv 5-axis machining chaw nrog Renishaw soj ntsuam. Rau lub tog raj kheej vaj tse uas yuav tsum tau ± 0.015 hli roundness hla 300 hli ntev, peb tshuab lub bore * tom qab * kev ntxhov siab-relieving lub casting-tsis ua ntej. Vim li cas? Vim tias peb tau ntsuas ntau npaum li cas qhov kev ntxhov siab seem cuam tshuam cov phab ntsa nyias nyias hauv ASTM A. Thiab peb paub tias kev hla cov kauj ruam no raug nqi ntau dua li lub sijhawm cub.
Qhov kev sib xyaw ntsug no muab peb qhov txiaj ntsig zoo:
- Dimensional kev kwv yees: Peb tuav GD&T callouts zoo li txoj hauj lwm kam rau ua ntawm Ø0.05 hli rau qhov chaw nres nkoj qhov chaw-tsim nrog Zeiss CMMs calibrated rau NIST qauv
- Microstructure kev ncaj ncees: Peb cov xuab zeb pwm siv cov resin-bonded silica nrog kev tswj permeability, kom ntseeg tau tias cov cua txias tsis sib xws uas tiv thaiv kom tsis txhob muaj porosity nyob rau hauv ib qho tseem ceeb load-bearing zones
- Kev npaj nto: Raws li-cam khwb cia nto raws li Ra 12.5 µm; machined finishes ntaus Ra 0.8 µm yam tsis muaj kev sib tsoo thib ob-tseem ceeb rau kev foob sib raug zoo hauv cov khoom siv siab
Thaum Koj Tshooj Tsis Nyob Hauv Ib Qho Khoom Muag
"Tsis-tus qauv" feem ntau txhais tau tias "lub luag haujlwm tseem ceeb." Xyoo tas los, European OEM xav tau lub cobalt-alloy plug rau AMS 5387-raws li lub twj tso kua mis sib dhos-tab sis nrog 17 ° helical xov sab hauv tsis muaj qhov tawm ntawm lub txee tuaj yeem txiav. Txuj kev xyaum? Weld-on inserts, ces caum threads. Peb cov kev daws teeb meem: kev cai-hauv av khoom-carbide daim ntawv cov cuab yeej khiav ntawm 85 m / min, nrog lub sijhawm tiag tiag kev co damping. Qhov tshwm sim? 100% xov daim ntawv ua raws, tsis muaj microcracks ntawm lub hauv paus vojvoog, thiab xa hauv 11 hnub - tsis yog 6 lub lis piam. Qhov no yog qhov tshwm sim thaum cov ntaub ntawv tshawb fawb, cov cuab yeej cuab yeej cuab tam, thiab kev pom zoo ntawm daim ntawv thov.
Peb niaj hnub tuav T800-raws li alloys, cobalt-nickel superalloys, thiab high-silicon grey irons uas cov pa machining tsis tau. Tab sis ntawm no yog qhov tseem ceeb tshaj: peb chij manufacturability txaus ntshai * ua ntej * quoting. Yog tias koj daim duab qhia txog 0.3 hli phab ntsa thickness nyob rau hauv ib tug nodular hlau bracket raug rau 5G poob siab loads-peb yuav qhia koj qhov tsawg kawg nkaus lub thickness raws li peb foundry lub solidification qauv. Tsis txhob thawb rov qab. Txhawm rau tiv thaiv kev ua tsis tiav.
Qhov "Reliable" Tiag tiag txhais tau tias hauv kev xyaum
Kev ntseeg tsis yog kev thov kev lag luam. Nws yog cov ntaub ntawv pov thawj. Txhua qhov cam khwb cia hlau peb nkoj nqa tag nrho traceability: kub tooj, tshuaj muaj pes tsawg leeg ib ASTM E353, tensile xeem tau, thiab ultrasonic soj ntsuam cov ntaub ntawv rau cov seem tseem ceeb. Tsis muaj "batch nruab nrab" qhia. Tsis muaj lus lees paub. Thaum lub tuam txhab North American oilfield kev pabcuam xav tau API RP 14C kev ua raws cai rau lub subsea winch vaj tsev, peb tau muab cov ntaub ntawv pov thawj thib peb - tsis yog cov ntawv txheeb xyuas sab hauv.
Qhov kev qhuab qhia no txuas mus rau logistics. Peb tsis cog lus tias "2 lub lis piam ua ntej" thiab tom qab ntawd tsis nrog huab cua thauj khoom. Peb cov kev ua haujlwm lean suav nrog cov sijhawm teem sijhawm, kev npaj muaj peev xwm ntawm lub cev, thiab ob qhov kev cog lus raw khoom. Rau nruab nrab-ntim xaj (50-500 pcs), peb tus nqi xa khoom raws sij hawm sawv ntawm 98.7% nyob rau 24 lub hlis dhau los - txheeb xyuas los ntawm cov neeg siv khoom xa tuaj, tsis yog cov dashboards sab hauv.
Xaiv txoj cai Cast Iron Part Factory pib nrog cov lus nug
Nug koj tus neeg muag khoom: Koj puas tuaj yeem muab daim ntawv qhia txog microstructure tsis ntev los no rau ASTM A? Koj puas ua cov txheej txheem CMM kuaj ntawm machined bores - lossis tsuas yog kev soj ntsuam zaum kawg? Dab tsi yog koj qhov kev sib txawv siab tshaj plaws rau cov ntsiab lus pearlite hauv grey hlau castings, thiab koj yuav ua li cas xyuas nws? Yog tias cov lus teb tsis meej, qeeb, lossis siv cov qauv dav dav yam tsis muaj cov ntsiab lus ntawm daim ntawv thov - koj tsis tham nrog cam khwb cia hlau ib feem Hoobkas. Koj tab tom tham nrog tus muag khoom.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsim qhov chaw uas qhov kev ua tsis tiav tsis yog qhov kev xaiv. Tsis yog vim peb hais li ntawd - tab sis vim tias txhua lub siab valve, txhua lub hauv paus twj tso kua mis, txhua lub winch center shaft roller ships nrog cov ntaub ntawv pov thawj nyob rau hauv nws cov qauv, nws cov kev ntsuas, thiab nws cov ntaub ntawv. Lub sij hawm tom ntej koj xav tau cam khwb cia hlau Cheebtsam rau xav tau kev lag luam daim ntaub ntawv, saib yav dhau los catalog. Saib cov txheej txheem hauv qab ntawm ntu.
