Muaj xuab zeb casting Hoobkas kev daws teeb meem xav tau ntau tshaj li cov hlau molten thiab pwm. Lawv xav tau kev tswj qhov loj me nyob rau hauv kev ntxhov siab thermal, microstructure sib xws thoob plaws 50-kg twj tso kua mis, thiab kev ncaj ncees ntawm qhov chaw uas muaj sia nyob 300-bar hydraulic cycling-tsis muaj rework. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau nrum ntau tshaj 12,000 hlau thiab hlau Cheebtsam txij li thaum 2018 qhov uas tsis ua hauj lwm tsis khawb-nws yog unplanned downtime nyob rau hauv ib tug offshore roj manifold los yog cavitation nyob rau hauv lub mining slurry twj tso kua mis. Tias yog vim li cas "kev lag luam xuab zeb casting Hoobkas" txhais tau tias ib yam dab tsi meej ntawm no: tsis ntim, tab sis txheeb xyuas qhov rov ua dua tshiab hauv cov khoom siv siab, cov ntawv ua haujlwm siab.
Xuab zeb Casting Tuav GD&T - Tsis yog Zoo li
Cov khw muag khoom xuab zeb feem ntau ua tau raws li ASTM A159 lossis EN-GJL-250 tensile specs. Ob peb tuav ± 0.15 hli ntawm 320-mm cylinder bore ID tom qab shakeout thiab kev ntxhov siab. Peb ua—vim peb cov txheej txheem pib ua ntej tus qauv kov cov xuab zeb. Peb cov engineers tshuaj xyuas koj cov GD&T callouts * ua ntej * pwm tsim, chij qhov twg cov kaum sab xis tsis sib haum nrog qhov tseeb txoj hauj lwm kam rau ua los yog qhov chaw tseem ceeb hloov kev pheej hmoo siab tshaj qhov kev txwv. Piv txwv li, piston twj tso kua mis lub tog raj kheej vaj tse yuav tsum tau concentricity ≤0.08 hli ntawm bore thiab flange mounting lub ntsej muag. Txheem ntsuab-xuab zeb txheej txheem drift tshaj 0.25 hli. Peb siv cov resin-bonded silica xuab zeb nrog tswj permeability (120-140) thiab precision core thawv machined rau ± 0.05 hli-ces xyuas txhua casting nrog Zeiss CONTURA CMM tiv thaiv tag nrho CAD kev sib piv. Tsis muaj kev xav. Tsis muaj "kaw txaus."
Qhov twg Cobalt Alloys Nres Lwm Cov Foundries
AMS 5387 cobalt alloy? T800-raws li nozzles rau abrasive slurry txhaj? Cov no tsis yog kev sib tw-lawv yog cov cuab yeej hlau. Txheem xuab zeb pwm tawg nyob rau hauv T800's 1,350 ° C ncuav kub. Sand erosion contaminates lub yaj. Grain coarsening ruins qaug zog lub neej. Peb daws qhov no hauv peb txheej: Ua ntej, kev cai ceramic-coated pwm nrog zirconia thaub qab tiv thaiv thermal shock thiab tiv thaiv silicon tuaj. Qhov thib ob, lub tshuab nqus tsev-pab pouring txiav turbulence - thiab tshem tawm cov pa roj uas ua rau microporosity nyob rau hauv cobalt lub qeeb solidification cheeb tsam. Thib peb, tom qab cov tshuaj cam khwb cia annealing ntawm 1,180 ° C ± 5 ° C, tuav rau 4 teev nyob rau hauv huab cua-tswj rauv, ces cua-txias kom kaw nyob rau hauv uniform Laves-theem dispersion. Cov txiaj ntsig: AMS 5387 xeem dhau ASTM E112 grain loj 4-6 tsis tu ncua. Cov neeg siv khoom qhia 3.2 × ntev kev pab cuam lub neej piv rau cov neeg sib tw castings nyob rau hauv high-pressure twj tso kua mis valve rooj zaum.
Vim li cas Vertical Integration Beats "Casting + Machining" Handoffs
Qee tus neeg muab khoom pov tseg lub tsev, xa mus rau lub khw CNC, tom qab ntawd rov xa nkoj kom tiav. Txhua qhov kev hloov pauv ntxiv muaj kev pheej hmoo: cov ntaub ntawv tsis raug cai, cov ntaub ntawv tsis raug kaw, cov ntaub ntawv kho cua sov poob. Peb tshuab txhua yam hlau casting-siab li qub, winch center ncej chais, twj tso kua mis foundations-nyob rau tib lub tsev kawm ntawv, siv cov as-cam khwb cia datum nto raws li cov ntaub ntawv. Peb 5-axis DMG MORI NTX 1000 tshuab txiav qhov kawg bores thaum tuav tus thawj pwm parting kab li Z-zero. Qhov ntawd tshem tawm qhov yuam kev ntau dhau los ntawm remounting. Nws kuj tseem tso cai rau peb tawm hauv cov khoom lag luam ntawm cov khoom siv tseem ceeb-0.8 hli ntawm T800 ntsaws ntsej muag, piv txwv li-yog li kev sib tsoo zaum kawg ua tiav Ra 0.4 µm * tom qab * kev kho cua sov, tsis ua ntej. Traceability yog built-in: txhua ntu nqa QR code txuas rau nws lub cav yaj, X-ray daim ntawv qhia, daim ntawv qhia hardness, thiab CMM cov txiaj ntsig. Tsis muaj ntawv txoj kev. Tsis muaj kwv yees.
Kev xa tawm tiag-tsis tau cog lus ua ntej
"8-12 lub lis piam" txhais tau tias tsis muaj dab tsi thaum koj lub tsheb engineering sib dhos kab nres ntawm lub lim tiam 10. Peb cog lus rau hnub xa khoom tsuas yog tom qab siv cov cuab yeej siv tau, cov ntaub ntawv pov thawj, thiab lub peev xwm - tsis yog tom qab hais tawm. Peb cov lean tsim cov hlwb khiav tas-batch cycles: ib lub pwm teem rau 14-hnub qhov rais, max 40 units ib batch rau complex steel castings. Qhov ntawd caps WIP, nthuav tawm cov fwj thaum ntxov, thiab lav tias peb xa cov qauv hauv 22 hnub - tsis yog "kom sai li sai tau." Xyoo tas los, 98.7% ntawm kev txiav txim xa tuaj rau lossis ua ntej hnub cog lus. 1.3% ncua? Tag nrho cov taug qab mus rau cov neeg siv khoom thov kev hloov pauv engineering * tom qab * kev pom zoo qauv - tsis ua haujlwm sab hauv. Peb qhia cov khoom siv sijhawm tiag tiag nrog cov neeg siv khoom tseem ceeb: pwm txheej xwm, ncuav cov cav, tshuaj xyuas lub sijhawm. Transparency tsis yog kev lag luam. Nws yog li cas koj tsis txhob tua hluav taws.
Yog tias koj xav tau lub chaw tsim khoom xuab zeb casting uas kho koj lub siab valve kos duab zoo li lub davhlau-tseem ceeb tivthaiv-tsis yog cov khoom lag luam-koj yuav tsum muaj pov thawj tswj kev coj tus cwj pwm, qhov tseeb qhov tseeb, thiab qhov kawg-rau-kawg tswv cuab. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. muab qhov ntawd. Tsis yog raws li kev cog lus. Raws li qhov tshwm sim rov ua tau.
