Thaum engineers qhia steel casting qhov chaw cov koom tes rau lub hom phiaj tseem ceeb hydraulic li qub, twj tso kua mis vaj tse, los yog offshore winch shafts, lawv tsis tsuas yog xav tau hlau poured rau hauv pwm. Lawv xav tau dimensional repeatability nyob rau hauv 0.02 mm kam rau ua. Microstructure sib xws ntawm 500-kg batch. Zero surprises nyob rau hauv kev kho cua sov teb. Thiab tag nrho traceability - los ntawm AMS 5387 cobalt alloy ingot daim ntawv pov thawj mus rau qhov kawg CMM daim ntawv qhia.
Peb tau pom ntau txoj haujlwm qeeb los ntawm cov chaw tsim khoom uas kho steel casting raws li cov txheej txheem khoom. Ib North American OEM poob peb lub hlis validating lub piston twj tso kua mis lub tog raj kheej vaj tse vim hais tias tus neeg muag khoom cov xuab zeb casting shrinkage qauv tsis phim qhov tseeb tom qab machining distortion. Lwm lub tuam txhab European hydraulics tau muab pov tseg 17% ntawm nws thawj qhov kev ua haujlwm tom qab qhov porosity-tsis pom thaum kuaj pom-ua rau lub siab to ntawm 420 bar. Cov no tsis yog rooj plaub ntug. Lawv yog cov tsos mob ntawm fragmented muaj peev xwm: casting ua nyob rau hauv ib lub khw, machining nyob rau hauv lwm, metallurgy outsourced mus rau ib tug thib peb.
Tias yog vim li cas cov kev txiav txim siab uas tau tsav los ntawm tam sim no tseem ceeb rau kev sib koom ua ke steel casting qhov chaw kev ua haujlwm - tsis yog rau kev tswj tus nqi xwb, tab sis rau physics-theem kwv yees. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua lub hlau thiab stainless hlau casting pib nrog cov khoom xaiv validated tiv thaiv ASTM A958, EN 10213, lossis cov neeg siv khoom tshwj xeeb tensile / cuam tshuam cov cai. Tsis muaj generic "316 stainless" hloov. Yog tias koj daim duab hu rau UNS S32750 super duplex nrog 45 HRC yam tsawg kawg nkaus tom qab kev daws teeb meem annealing, lawv cov cav tov rauv thiab cov ntaub ntawv qhia txog qhov tawv tawv qhia raws nraim qhov ntawd - tsis yog daim ntawv hla / poob ntawm ib daim ntawv.
Lawv qhov chaw ISO-raws li kev tswj hwm kev nqis peev thiab cov xuab zeb casting - tab sis tsuas yog qhov twg txhua txoj kev xa cov txiaj ntsig ntsuas tau. Kev nqis peev casting rau nyias-walled cobalt alloy nozzles yuav tsum tau ± 0.05 hli phab ntsa thickness tswj. Xuab zeb casting rau qhov loj-inch engineering tsheb winch center ncej chais, qhov twg tswj cov cua txias tiv thaiv microcracking hauv T800-raws li alloys. Qhov tseem ceeb, machining tsis yog qhov kev xav tom qab. Lawv multi-axis CNC hlwb zaum meters los ntawm hauv pem teb casting. Qhov sib thooj ntawd ua rau muaj kev ntxhov siab tom qab kev ntxhov siab tam sim ua ntej kev ua haujlwm tsis zoo - thiab cov lus tawm tswv yim ntawm lub sijhawm tiag tiag ntawm cov kws tsim hlau metallurgists thiab NC programmers thaum warpage tshaj cov qauv kev kwv yees.
Nov yog dab tsi cais lawv los ntawm broad-spectrum foundries:
- Alloy kev qhuab qhia, tsis yog alloy ntau yam. Lawv tsis thov kev tshaj lij hauv 27 qib nickel-based. Lawv paub AMS 5387, T800, thiab UNS R30003-tshwj xeeb rau cov twj tso kua mis siab qhov chaw uas carbide cais ncaj qha cuam tshuam rau lub neej qaug zog. Lawv cov txheej txheem kho cua sov muaj xws li qeeb-txias ramping curves validated ntawm qhov tseeb geometries, tsis yog daim coupon xwb.
- GD & T-ua ntej kev tsim khoom. Thaum koj xa ib daim duab nrog rau txoj hauj lwm kam rau ua ntawm Ø12 hli bores txheeb ze rau lub dav hlau datum, lawv cov kev ntsuam xyuas engineering chij muaj peev xwm cuam tshuam kev cuam tshuam * ua ntej * kev pom zoo qauv - tsis yog tom qab thawj tsab xov xwm tshuaj xyuas ua tsis tiav. Lawv daim ntawv qhia txhua qhov tseem ceeb GD&T callout rau ib qho kev sojntsuam CMM tshwj xeeb, kev ntsuas kho qhov muag, lossis kev sim ua haujlwm.
- Tsis muaj "black box" zoo. Txhua steel casting nkoj nrog cov ntaub ntawv digital: raw cov ntaub ntawv zeb xeem cov ntaub ntawv, spectrographic tsom xam ib yaj, thermal voj voog kab kos, cov ntaub ntawv soj ntsuam qhov ntev (CMM + optical), thiab nto tiav Ra / Rz ntsuas. Tsis yog cov ntsiab lus. Cov ntaub ntawv nyoos. Traceable rau cua sov tooj, tus neeg teb xov tooj ID, thiab tshuab serial tooj.
Qee tus yuav sib cav tias cov chaw tsim khoom hauv cheeb tsam muab kev hloov pauv sai dua. Tab sis ceev yam tsis muaj kev twv yuav raug nqi ntau dua. Lub sij hawm rushed 4-lub lim tiam tsis txhais hais tias tsis muaj dab tsi yog tias qhov thib ob batch yuav tsum tau rov ua haujlwm vim qhov tsis sib haum ntawm graphite nodule suav hauv cov hlau castings - lossis yog tias cov hlau tsis xeb hlau casting cov ntsiab lus ferrite drifts sab nraum 3-12% ntau yam, cuam tshuam corrosion kuj hauv cov pa roj qaub. QINGDAO QIANGSENYUAN txoj haujlwm lean workflow tsis txi cov kauj ruam pov thawj; nws sequences lawv los tiv thaiv rework. Cov khoom xa tuaj tau raug txheeb xyuas * ua ntej * kev npaj pwm. Qhov loj me tseem ceeb tau kuaj * tom qab * kev ntxhov siab tab sis * ua ntej * zaum kawg hardening. Kev sim ua haujlwm tshwm sim * tom qab * qhov chaw tiav - tsis yog qhov rooj zaum kawg.
Rau cov pab pawg muag khoom ntsuas a steel casting qhov chaw, nug peb lo lus nug: Lawv puas tuaj yeem qhia koj daim ntawv qhia CMM rau cov khoom sib xws hauv geometry, alloy, thiab chav kawm kam rau koj li? Lawv puas tuav cov ntawv pov thawj tam sim no rau koj lub hom phiaj kev lag luam-ASME BPVC Tshooj II rau qhov chaw siab, API 6A rau cov khoom siv roj av, lossis PED 2014/68/EU? Thiab qhov tseem ceeb tshaj plaws: Puas yog lawv pab neeg ua haujlwm koom ua ke kos npe rau koj daim duab kos duab cov ntawv sau ua haujlwm - suav nrog cov lus qhia radii, cov kaum sab xis, lossis kev hloov kho qhov rooj - nrog cov lus sau tseg?
Lub ntsiab lus kawg no tseem ceeb vim tias qhov tsis xws luag tsis tshua muaj tshwm sim ntawm lub ncuav. Lawv pib nyob rau hauv qhov tsim-rau-tsim qhov sib txawv. QINGDAO QIANGSENYUAN tus thawj tswj hwm qhov project tsis yog sau cov duab kos xwb-lawv piav qhia lawv. Lawv yuav chij ib lub vojvoog 0.3 hli ntawm lub ces kaum kev ntxhov siab vim tsis txaus rau AMS 5387 qhov kub kub tearing nyiam. Lawv yuav pom zoo kom hloov qhov chaw luam ntawv tseem ceeb kom tsis txhob ua yuam kev hauv 120-mm-thick seem. Qhov no tsis yog kev tawm tswv yim fluff. Nws tau sau tseg tias muaj kev pheej hmoo txo qis rov qab los ntawm 14 xyoo ntawm hydraulic system tivthaiv kev tsim khoom thoob plaws North America, Europe, thiab Southeast Asia.
Saib tom ntej, qhov kev thov rau cov txheej txheem hybrid - qhov ze-net-puab casting ua tau raws li qhov tseeb txiav tawm machining-yuav tsis qeeb. Tom ntej no-tiam twj tso kua mis vaj tse yuav tsum tau nyob rau hauv cov kev khiav dej num tsis yooj yim sua kom cam khwb cia huv si, tseem nyuaj heev rau ib txwm tig. Lub neej yav tom ntej belongs rau cov neeg koom tes uas kho casting thiab machining raws li interdependent physics teeb meem, tsis sequential nqi chaw. QINGDAO QIANGSENYUAN's R & D tsom rau kev ua haujlwm ntawm kev ua haujlwm thermal ua qauv qhia txog qhov tseeb. Lawv cov ntawv pov thawj tom ntej thawb lub hom phiaj NADCAP AC7114 rau kev sim tsis muaj kev puas tsuaj-vim rau cov hlau alloy siab ua haujlwm ntawm 500 ° C thiab 700 bar, "tsis pom qhov tsis xws luag" tsis txaus. Koj xav tau cov ntaub ntawv qhia txog theem tshwj xeeb ultrasonic attenuation.
Yog tias koj daim ntawv thov xav kom tsis muaj kev cuam tshuam txog kev ncaj ncees ntawm cov qauv, qhov kev ncaj ncees, lossis cov khoom siv traceability - ces txoj cai steel casting qhov chaw tsis yog tus pheej yig tshaj bidder. Nws yog qhov uas nws cov txheej txheem cov ntaub ntawv nyeem zoo li phau ntawv physics, uas nws cov ntaub ntawv soj ntsuam zoo li cov phau ntawv kuaj, thiab cov engineers hais koj cov lus GD&T tau zoo. Qhov kev txiav txim siab ntawd tsis tshwm sim los ntawm kev sib tsoo. Nws yog engineered-batch tom qab batch, ib feem tom qab ib feem.
