Thaum engineers qhia a steelcasting foundry Hoobkas, lawv tsis yog tsuas yog xaj hlau - lawv tau cog lus rau qhov kev ruaj ntseg nyob rau hauv 300 bar, microstructure kev ncaj ncees tom qab thermal cycling, thiab xoom kam rau ua rau porosity nyob rau hauv high-wear zones. Peb tau pom ntau txoj haujlwm qeeb vim tias cov neeg muab khoom pov tseg tau kho cov hlau li "tsuas yog lwm cov hlau nplaum." Nws tsis yog. Tsawg-alloy steels tawg nyob rau hauv ceev quenching. Cov qib stainless xws li CF8M cais yog pwm txias tus nqi drift los ntawm ± 5 ° C. Thiab cobalt-based twj tso kua mis-tshwj xeeb tshaj yog AMS 5387 lossis T800-xav tau metallurgical txuas ntxiv thoob plaws txhua qhov cua sov, tsis yog ua raws li daim ntawv qhia tshwj xeeb.
Vim li cas hlau Casting tsis ua ntej machining txawm pib
Feem ntau cov kev ua tsis tiav rov qab mus rau peb qhov kev zam tsis tau: cov khoom siv uas tsis muaj ntawv pov thawj batch-theem, cov xuab zeb pwm tsim uas tsis quav ntsej cov kev taw qhia kev ruaj ntseg hauv cov vaj tsev tuab tuab, thiab cov sij hawm kho cua sov sib nrauj los ntawm qhov tseeb geometry. Ntawm peb lub chaw Qingdao, peb sim cov khoom 316L tuaj rau cov ntsiab lus ferrite * ua ntej * nchuav - tsis yog tom qab. Peb daim ntawv qhia thermal gradients hauv cov xuab zeb pwm siv cov thermocouples embedded thaum sim nchuav. Thiab peb yeej tsis siv tib lub voj voog mus rau 45-kg piston twj tso kua mis vaj tsev thiab 2.3-kg siab valve lub cev. Ib qho me me haum tsis muaj dab tsi hauv precision steel casting.
Yog vim li cas peb muab cov txheej txheem casting ncaj qha rau hauv GD&T tshuaj xyuas. Thaum tus neeg siv khoom xa daim duab kos rau lub tog raj kheej stainless hlau vaj tse nrog ± 0.05 hli txoj hauj lwm kam rau ua rau rau mounting bores, peb tsis yog hais txog machining. Peb nug: Lub rooj vag nkag qhov twg? Cov ntawv luam tawm twg yuav hloov pauv thaum shakeout? Ntau npaum li cas tom qab cam khwb cia distortion tshwm sim ntawm 650 ° C? Cov no tsis yog cov lus nug theoretical. Lawv raug ntsuas - ntawm cov khoom siv tiag tiag, nrog CMM cov ntaub ntawv nkag rau thawj CAD qhov chaw.
Vertical Integration uas yeej tswj kev sib txawv
Outsourcing casting, tom qab ntawd machining, tom qab ua tiav tsim peb qhov kev sib tw - thiab peb lub sijhawm rau kev ua yuam kev. Peb steelcasting foundry Hoobkas khiav peev thiab xuab zeb casting * hauv tib lub tsev ISO-certified * qhov chaw CNC ua haujlwm. Lub cobalt-nickel ntsaws cam khwb cia ntawm 1,420 ° C txav ncaj qha mus rau kev ntxhov siab-relief annealing, ces mus rau tsib-axis milling-tag nrho hauv 48 teev. Tsis muaj kev thauj mus los ntawm qhov chaw. Tsis muaj re-fixturing. Tsis muaj cov ntaub ntawv ploj lawm.
Qhov no tsis yog yooj yim - nws yog physics-tsav tswj. Thermal expansion sib txawv ntawm pwm xuab zeb, molten steel, thiab machined fixture daim hlau raug txo kom tsawg thaum tag nrho cov kauj ruam tshwm sim nyob rau hauv ib lub ru tsev nrog sib koom ib puag ncig saib xyuas. Peb taug qab ambient humidity thiab ambient kub ib teev - tsis yog vim nws yog "kev xyaum zoo," tab sis vim hais tias peb tau ntsuas yuav ua li cas ib tug 3% RH viav vias hloov pwm kom qhuav lub sij hawm txaus los hloov nto roughness ntawm qhov tseem ceeb sealing ntsej muag.
- CNC-machined steel castings: ≤0.015mm daim ntawv sib txawv ntawm 300 hli spans

Kev ua tau zoo hauv ntiaj teb, Tsis yog Daim Ntawv Ua Raws Cai
Qee tus neeg xa khoom xa khoom xa khoom xa tuaj nrog "ISO 9001 tau lees paub" thwj rau ntawm daim ntawv ntim khoom - tab sis tsis tuaj yeem tsim ib daim ntawv pov thawj kev xeem uas qhia txog cov tawv tawv hla ntawm 120-mm-tuab twj tso kua mis. Peb ua. Txhua qhov khoom xa tuaj suav nrog daim ntawv tshaj tawm cov khoom siv (MTR) nrog tensile, yield, elongation, thiab cuam tshuam qhov tseem ceeb - ntsuas los ntawm daim coupon txiav * los ntawm tib lub casting *, tsis yog los ntawm ib qho kev sim cais.
Peb kuj validate functional performance ua ntej shipping. Lub winch center ncej cov menyuam tsis yog kuaj xyuas txoj kab uas hla. Nws tig ntawm 1,200 rpm ntawm peb lub load-dynamometer rig thaum lub zog ntsuas ntsuas saib deflection ntawm peb txoj haujlwm radial. Lub siab valve vaj tsev tsis yog dhau qhov kev ntsuas hydrostatic ntawm 1.5 × ua haujlwm siab. Nws cycles 5,000 zaug nrog simulated thermal shock-200 ° C mus rau 25 ° C nyob rau hauv 90 vib nas this-tom qab ntawd mus soj ntsuam dye-penetrant. Yog tias nws tawg, peb rov tsim dua qhov system riser - tsis yog NDT txheej txheem.
Yuav Thov Li Cas Los Ntawm Koj Tus Tswv Cuab Casting
Tsis txhob hais rau "peb nrum steel." Nug es tsis txhob:
- Koj puas tuaj yeem qhia kuv qhov kawg peb lub cav cua sov rau koj ASTM A216 Qib WCB cov khoom siv-thiab paub meej tias txhua yam tau txais los ntawm tib lub hauv paus zeb?
- Koj puas simulate solidification hauv MAGMAsoft lossis zoo sib xws ua ntej pom zoo tsim pwm?
- Puas yog koj qhov kev tshuaj ntsuam zaum kawg ua tiav ntawm CMM ntsuas-lossis nrog cov micrometers tuav thiab mus / tsis mus gages?
- Thaum lub casting tsis pom kev kuaj, koj puas muab pov tseg-los yog ua cov hauv paus-ua rau kev soj ntsuam ntawm kev suav nrog, roj porosity faib, thiab dendrite caj npab sib nrug?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. teb yog rau tag nrho plaub. Tsis yog raws li kev thov kev lag luam - tab sis raws li cov ntaub ntawv ua haujlwm cov kauj ruam, pom hauv peb cov ntaub ntawv tsim khoom thiab tshawb xyuas tau thaum cov neeg siv khoom tshawb xyuas. Peb tsim steel castings rau hydraulic systems uas khiav 18,000 teev yam tsis muaj foob hloov. Rau oilfield twj tuav H₂S-laden kua ntawm 120 ° C. Rau engineering tsheb winches nqa 8.5-tuj loads nyob rau hauv sub-zero tej yam kev mob. Kev ntseeg tsis yog lub hom phiaj. Nws yog qhov tso tawm ntawm cov txheej txheem tswj - ntsuas, rov ua dua, ua pov thawj.
Yog tias koj qhov kev txiav txim siab steel tom ntej yuav tsum muaj ntau dua qhov kev sib haum xeeb - yog tias nws xav tau cov qauv kev kwv yees, kev sib luag ntawm cov hlau, thiab kev siv tau zoo - pib nrog cov txheej txheem pob tshab. Tsis yog daim ntawv qhia. Tsis yog ntawv pov thawj ib leeg. Tab sis lub sijhawm nkag mus rau cov ntawv pov thawj, cov kab kos kev kho cua sov, thiab CMM cov ntaub ntawv. Ua li no a steelcasting foundry Hoobkas khwv tau nws qhov chaw nyob rau hauv lub hom phiaj tseem ceeb mov chains.
