Thaum cov engineers qhia lub ntiajteb txawj nqus tuag casting qhov chaw rau hydraulic li qub los yog high-pressure twj tso kua mis vaj tse, lawv tsis yog tsuas yog yuav hlau - lawv nyob ruaj ruaj nyob rau hauv 300+ bar kev khiav hauj lwm siab, microstructural kev ncaj ncees tom qab kev kho cua sov, thiab nto tiav uas yuav tsis noob corrosion nyob rau hauv ntsev-laden offshore ib puag ncig. Yog vim li cas a gravity tuag casting qhov chaw Hoobkas yuav tsum tau ua ntau tshaj li cov hlau molten rau hauv steel pwm. Nws yuav tsum tswj cov nqi zog hauv ± 2 ° C, txheeb xyuas cov txiaj ntsig zoo nrog kev kuaj ultrasonic, thiab tuav GD&T tolerances nruj dua ISO 2768-mK-tshwj xeeb tshaj yog thaum casting cobalt-nickel alloys xws li AMS 5387 lossis T800.
Vim li cas lub ntiajteb txawj nqus tuag Casting xav tau ntsug kev koom ua ke - Tsis yog Pwm thiab Molten Hlau
Feem ntau qhov ua tsis tiav hauv cov khoom siv ua haujlwm siab-koob rov qab mus rau ib qho hauv paus ua rau: txheej txheem kev ua haujlwm. Ib tug foundry cam khwb cia ib feem. Ib lub khw muag khoom sib cais xyaum ua kom txias qhov chaw nres nkoj. Lwm tus neeg muag khoom siv HVOF txheej. Txhua qhov kev hloov pauv yuav muaj kev cuam tshuam tsis zoo, thermal distortion, lossis cov ntaub ntawv tsis muaj ntaub ntawv hloov pauv. Peb tau pom peb lub piston twj tso kua mis lub tog raj kheej cov tsev nyob tsis lees paub hauv kev sib dhos zaum kawg - tsis yog vim qhov porosity, tab sis vim tias CNC-machined valve lub rooj qhov tob sib txawv los ntawm 0.018 hli hla cov khoom siv vim tsis sib xws li-cam khwb cia datum nto.
Yog vim li cas qhov tseeb precision pib ua ntej thawj ncuav. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., casting thiab machining qhia tib lub chaw ntsuas ntsuas, tib cov khoom siv ntau ntxiv, thiab tib txoj kev soj ntsuam. Thaum peb nrum lub siab valve lub cev nyob rau hauv ASTM A494 CW6MC, tib CMM txheeb xyuas ob qho tib si li-cam khwb cia kab noj hniav geometry * thiab * qhov kawg machined sealing nto-siv tib kub-stabilized granite puag, tib calibrated sojntsuam, tib GD&T siv ncej. Tsis muaj re-fixturing. Tsis muaj kev sib koom tes txhais lus. Tsuas yog traceable txuas ntxiv ntawm cov kua hlau mus rau kev ua haujlwm.
Qhov no tsis yog theoretical. Nws yog li cas peb xa winch center ncej chais rau engineering tsheb khiav hauj lwm ntawm -40 ° C mus rau +85 ° C ambient, nrog hardness sib xws ntawm HRC 58-62 nyob rau hauv tag nrho cov 1.2-meter ntev-txawm hais tias cov menyuam lub tapered profile tsim tsis sib xws phab ntsa thickness thiab tsis yog-uniform txias.
Qhov twg Standard Foundries Nres-Thiab Vim Li Cas Cobalt Alloys Xav Tau Ntau
Qee cov tuam txhab lag luam kho cobalt-raws li lub ntiajteb txawj nqus tuag casting li "tsuas yog lwm alloy." Qhov kev xav ntawd ua tsis tau sai. T800 thiab AMS 5387 tsis coj zoo li txhuas lossis txawm tias tus qauv stainless hlau. Lawv thermal conductivity yog 1/5 ntawm 304 stainless. Lawv solidification shrinkage yog 3.2%, tsis yog 1.8%. Thiab lawv cov kub tearing susceptibility spikes saum 1,250 ° C - txoj cai uas feem ntau tuag preheat cycles zaum.
Peb kho qhov no nyob rau lub sijhawm tiag tiag: pwm preheat tuav ntawm 320 ° C ± 5 ° C (tsis yog 250-400 ° C), rooj vag tsim rau laminar ntws hauv qab 0.8 m / s, thiab risers loj siv kev simulation-tsis yog txoj cai ntawm tus ntiv tes xoo. Txhua cobalt alloy casting undergoes tom qab cam khwb cia tshuaj annealing ntawm 1,180 ° C rau 4 teev, ces dej quenched nyob rau hauv 15 vib nas this - sij hawm nrog industrial-qib pyrometers, tsis timers. Deviate los ntawm 30 vib nas this? Grain ciam teb carbides precipitate. Ua tsis tiav ASTM E112 grain loj xeem. Qhwv lub batch.
Cov neeg siv khoom nug: "Koj puas tuaj yeem pov peb lub tshuab tsis zoo nozzle geometry hauv AMS 5387?" Peb teb nrog cov ntaub ntawv-tsis tau cog lus. Peb qhia lawv cov thermal daim ntawv qhia los ntawm peb MAGMASOFT® simulation, qhov tseeb CMM scan ntawm tus qauv lub sab hauv txias channel, thiab Rockwell C hardness profile hla qhov tseem ceeb 2-mm-thick tip seem. Yog tias nws tsis ua raws li qhov tshwj xeeb ntawm thawj zaug sim, peb hloov kho tus qauv tuag - tsis yog daim duab.
Dab tsi "ISO-Compliant" Tiag tiag txhais tau tias ntawm Lub Khw Pem Teb
ISO 9001 ntawv pov thawj zaum ntawm phab ntsa. Qhov tseem ceeb yog dab tsi tshwm sim ntawm lub rooj ntev zaum. Ntawm peb qhov chaw Qingdao, txhua qhov kev sib nqus tuag casting tau txais peb qhov kev tshuaj xyuas ywj pheej: cov khoom siv raw khoom pov thawj (spectrometry + tensile bar test), hauv kev ntsuas qhov ntev ntawm 30% thiab 70% tiav (CMM + optical comparator), thiab qhov kawg ua haujlwm validation - suav nrog kev ntsuas hydrostatic siab rau lub cev thiab ntsuas ntsuas 450 bar.
Peb khaws tag nrho traceability - tsis yog cov xov tooj cua sov xwb. Txhua qhov txuas mus rau nws qhov tseeb yaj cav, suav lub voj voog tuag, lub tshuab hluav taws xob O₂ nyeem ntawv thaum lub sij hawm annealing, thiab tus neeg teb xov tooj ID. Yog tias tus neeg siv khoom qhia txog qhov tsis txaus ntseeg hauv kev ua haujlwm, peb rub tag nrho cov ntxaib digital hauv 90 feeb: qhov ntsuas qhov ntsuas, cov cuab yeej siv lub cav siv lub cav, ntsuas qhov roughness, txawm tias cov av noo nyeem hauv lub rooj muag khoom tiav hnub ntawd.
- Cov ntaub ntawv nyoos tsuas yog los ntawm cov zeb tau lees paub rau ASTM A957 / EN 1559-3
- Tag nrho cov cobalt alloy castings kuaj ib ASTM E125 rau kev soj ntsuam cov khoom sib nqus
- Dimensional ua raws li kev txheeb xyuas tawm tsam ASME Y14.5-2018, tsis yog "tso tawm"
- Tsis muaj "kev pom zoo thawj kab lus" yam tsis muaj kev sim ua haujlwm - tsis muaj kev zam
Xaiv tus khub zoo tsis yog hais txog lub peev xwm-Nws yog hais txog kev tswj tsis yooj yim
A gravity tuag casting qhov chaw Hoobkas nrog 200 tons / hli muaj peev xwm txhais tau tias me ntsis yog tias nws tsis tuaj yeem tuav ± 0.025 hli ntawm 300-mm cobalt alloy vaj tsev thaum tswj cov qauv coj ua. Dab tsi tseem ceeb yog pab neeg nkag siab tob npaum li cas yog vim li cas koj lub twj tso kua mis lub hauv paus tawg ntawm 12,000-teev lub sijhawm ua haujlwm - lossis yog vim li cas koj lub siab valve tawm tom qab thermal cycling.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsom tshwj xeeb tshaj yog rau plaub qhov kev sib tw siab: cov khoom siv hydraulic, cov khoom siv roj & roj, engineering tsheb tshuab, thiab cov twj tso kua mis tshwj xeeb. Peb tsis cam khwb cia zoo nkauj brackets los yog low-pressure vaj tse. Peb daws cov teeb meem uas tsis ua haujlwm nres cov kab ntau lawm, ua rau muaj kev nyab xeeb kaw, lossis ua txhaum API 6A lossis ISO 15156 cov cai.
Peb cov kauj ruam tom ntej? Embedding real-time solidification soj ntsuam ncaj qha mus rau hauv cov kab noj hniav tuag-thiab txuas cov thermal profiles rau kev kwv yees saib xyuas qauv rau cov neeg siv khoom kawg. Tsis yog vim nws yog qhov tshiab. Vim tias nws txo qis qis qis los ntawm 22% hauv kev sim ua haujlwm. Qhov ntawd yog qhov tseeb uas tsis nyob hauv daim ntawv qhia. Nws nyob hauv ib feem.
