Thaum engineers qhia a steel casting qhov chaw Hoobkas, lawv tsis yog tsuas yog xaj hlau - lawv tab tom twv ntawm qhov kev ruaj ntseg nyob rau hauv 350-bar hydraulic siab, microstructural kev ncaj ncees tom qab thermal cycling, thiab xoom kam rau porosity nyob rau hauv lub twj tso kua mis vaj tse uas khiav 24/7 nyob rau hauv offshore rigs. Tias yog vim li cas ntau dua 60% ntawm peb cov lus xaj rov qab los ntawm North American oilfield service tuam txhab pib nrog ib lo lus nug: "Koj puas tuaj yeem cam khwb cia, tshuab, thiab ntawv pov thawj AMS 5387 cobalt alloy-* nyob rau hauv tib lub chaw *, nrog tag nrho batch traceability?"
Peb tau xa 12,400+ steel thiab stainless hlau castings txij li xyoo 2018 - tsis yog cov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Lub piston twj tso kua mis lub tog raj kheej yuav tsum tuav qhov tseeb rau ± 0.015 hli hla 420 hli ntev tom qab kev kho cua sov. Lub winch center ncej cov menyuam yuav tsum muaj sia nyob abrasive xuab zeb thauj khoom thaum tig ntawm 180 RPM hauv qab 90 kN torque. Cov no tsis yog machining kam rau ua. Lawv yog cov txheej txheem casting tshwm sim - dictated los ntawm pwm tsim, gating simulation, solidification tswj, thiab post-cast stress nyem. Qhov ntawd yog qhov uas cov neeg muag khoom feem ntau tawg.
Feem ntau steel casting ib feem factories cais casting los ntawm precision xov. Lawv outsource CNC ua hauj lwm los yog cia siab rau cov neeg thib peb cov neeg kho cua sov. Peb tsis ua. Peb lub chaw ISO 9001-certified nyob rau hauv Qingdao integrates peev casting, xuab zeb casting, multi-axis machining (txog 5-axis ib txhij), nqus cua sov kho, thiab nto finishing-tag nrho nyob rau hauv ib lub ru tsev thiab ib tug zoo system. Thaum ib tug European OEM xa peb GD & T-hnyav daim duab rau lub siab valve lub cev nrog 17 cov ntaub ntawv tseem ceeb, peb ntes tau peb manufacturability tsis sib haum xeeb * ua ntej tooling pib *: ib tug undercut tsis yooj yim sua mus cam khwb cia yam tsis muaj cores, ib tug nyias-phab ntsa seem prone rau shrinkage kab noj hniav, thiab ib tug nto tag callout incompatible as-cam khwb cia roughness. Peb tau npaj geometry tweaks-validated ntawm MAGMASOFT® solidification simulation-thiab txiav lawv cov qauv coj lub sij hawm los ntawm 37%.
Nov yog qhov teeb tsa kev ua tau zoo sib nrug los ntawm cov ntawv thov catalog:
- Kev tswj cov khoom pib ua ntej melting: Peb muab cov ntaub ntawv pov thawj cov cua sov los ntawm cov mills nrog EN 10204 3.1 mill test reports - thiab cross-verify chemistry ntawm OES spectroscopy thaum tau txais. Tsis muaj kev zam rau T800 cobalt-based alloys lossis ASTM A487 Qib CA6NM stainless hlau.
- Casting tsis yog nchuav hlau xwb: Rau high-pressure hydraulic vaj tse, peb siv ceramic plhaub peev casting nrog tswj dewaxing thiab burnout cycles. Rau loj engineering tsheb thav ntawv, peb siv resin-bonded xuab zeb pwm nrog real-time ntsuas kub thaum lub sij hawm ncuav. Txhua ntau dhau mus kuaj ultrasonic ib ASTM E114 thiab radiography ib ISO 5579 Class B.
- Qhov tseeb qhov tseeb nyob hauv chav CMM: Txhua qhov ua tiav tau raug tshuaj xyuas ntawm Zeiss Contura G2 RDS tswj lub tshuab ntsuas. Tsis yog nyob rau theem kawg nkaus xwb-peb txheeb xyuas cov yam ntxwv tseem ceeb tom qab kev ua haujlwm tsis zoo, tom qab kev kho cua sov, thiab tom qab ua tiav tiav. Tag Nrho GD&T tshaj tawm suav nrog txoj haujlwm tseeb, profile, thiab cov ntaub ntawv khiav tawm khi rau cov neeg siv khoom tshwj xeeb cov ntaub ntawv.
Ib txhia yuav sib cav hais tias offshore casting tsev muab tus nqi qis dua. Tab sis thaum ib tus neeg Esxias sab hnub tuaj tau hloov los ntawm tus neeg muag khoom qis rau peb, lawv pom lawv "txuag nqi" suav nrog 22% seem ntawm stainless hlau twj tso kua mis vim qhov tsis muaj qhov tsis hnov tsw ntawm qhov porosity - thiab xoom cov khoom siv taug qab thaum ua tsis tiav hauv thaj teb. Peb tsis sib tw ntawm tus nqi ib leeg. Peb sib tw ntawm tag nrho cov nqi ntawm cov tswv cuab: tsawg dua rov ua dua tshiab, tsis muaj kev rov qab los ntawm thaj chaw, qhov kev xa khoom tuaj yeem kwv yees, thiab kev txhawb nqa engineering uas hais GD&T tau zoo - tsis yog lus Askiv xwb.
Peb lub zog sib txawv? Peb tshwj xeeb hauv qhov uas lwm tus zam. Cobalt-nickel alloys zoo li AMS 5387 tsis yog "nyuaj rau tshuab." Lawv cov thermal conductivity yog 1/4 ntawm cov hlau tsis muaj steel, lawv cov kev ua haujlwm hnyav tshaj 300%, thiab cov kev ntxhov siab ntawm qhov tsis sib xws tuaj yeem cuam tshuam ib feem ntawm 0.12 hli thaum hmo ntuj. Peb tau tsim cov cuab yeej tshwj xeeb hauv tsev qiv ntawv, cov khoom xa tawm kev cai, thiab cov tswv yim ua haujlwm qeeb qeeb uas tau lees paub thoob plaws 8,200+ cobalt alloy qhov chaw. Thaum ib lub chaw tsim khoom hauv Teb Chaws Asmeskas xav tau cov tshuab tsis zoo nrog cov contours nrog API RP 14E yaig qauv, peb nrum qhov ze-net duab, tom qab ntawd siv electrochemical machining (ECM) rau qhov kawg contour-vim cov cuab yeej siv pa yuav tawg.
Yog tias koj qhov project tom ntej no suav nrog kev xaiv cov khoom lag luam steel, nug peb cov lus nug no: Puas yog tus neeg muag khoom muaj lawv cov txheej txheem casting-lossis subcontract nws? Lawv puas tuaj yeem muab cov ntawv pov thawj zeb, cov ntaub ntawv kho cua sov, thiab CMM cov ntaub ntawv rau * txhua qhov khoom xa tuaj *? Thiab lawv puas chij tsim kev pheej hmoo ua ntej hais - lossis tos kom txog thaum thawj tsab xov xwm ua tsis tiav? Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb teb yog - ces ua pov thawj nrog cov ntaub ntawv, tsis yog daim ntawv qhia. Vim kev ntseeg tsis tau cog lus tseg. Nws yog ntsuas, ntaub ntawv, thiab xa.
