Thaum cov kws tshaj lij qhia cov neeg koom tes stainless hlau precision casting Hoobkas, lawv tsis yog tsuas yog xaj khoom-lawv tab tom ua kom ruaj khov nyob rau hauv 300 bar hydraulic siab, corrosion kuj nyob rau hauv qaub roj ib puag ncig, thiab microstructural kev ncaj ncees tom qab kev kho cua sov. Yog vim li cas peb thiaj li tau pom cov neeg siv khoom rov qab los ntawm North American oilfield cov tuam txhab kev pabcuam rov qab nrog cov twj tso kua mis tshiab hauv tsev tsuas yog 12 lub lis piam tom qab xa khoom thawj zaug: lawv tau sim cov txheej txheem ua tiav ntawm AMS 5387 cobalt alloy nozzles hauv lub ntiaj teb tiag tiag reciprocating tsab ntawv tsa suab-thiab pom xoom microcracking ntawm lub rooj sib tshuam.
Vim li cas cov khoom coj tus cwj pwm dictates txheej txheem xaiv-tsis yog nqi
Stainless hlau peev casting ua tsis tau thaum pab pawg kho nws zoo li carbon hlau. Peb tau saib peb lub tsev muag khoom vim tias cov neeg tsim qauv tau teev 316L castings rau lub voj voog piston twj tso kua mis uas tsis muaj kev suav nyiaj rau kev ua kom muaj zog shrinkage anisotropy. Qhov tshwm sim? Machined bores drifted 0.04 hli tawm ntawm GD&T kam rau ua tom qab kev ntxhov siab. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb cov txheej txheem pib nrog thermal qauv - tsis hais. Rau txhua txhua stainless hlau precision casting Hoobkas thov, peb simulate solidification txoj kev siv MAGMAsoft mus rau txoj hauj lwm risers qhov twg dendritic pub compensates rau hauv zos contraction. Qhov ntawd yog li cas peb tuav ± 0.025 hli ntawm Ø120 hli lub tog raj kheej bore IDs yam tsis muaj kev ua haujlwm tom qab-tseem ceeb thaum phab ntsa thickness poob mus rau 8.3 hli nyob rau hauv siab ports.
Qhov no tsis yog theoretical. Peb lub hlis dhau los, German engineering tsheb OEM xav tau winch center ncej chais hauv 17-4PH stainless hlau. Lawv cov khoom lag luam ua ntej tau xa 12% seem vim interdendritic microporosity nyob ze cov fins txias. Peb kho qhov rooj geometry, txo qhov kub ntawm 42 ° C, thiab qhia lub tshuab nqus tsev kom qhuav. Yield dhia mus rau 94%. Qhov sib txawv tsis zoo dua cov cuab yeej - nws yog metallurgical kev qhuab qhia ua ntej thawj wax qauv luam tawm.
Qhov twg Vertical Integration daws cov kev ua tsis tiav tiag tiag
Qee tus neeg muag khoom tawm ntawm cov khoom siv los txiav cov nqi. Qhov ntawd ua rau pom kev pheej hmoo tsis pom: xuab zeb-cam khwb cia 304 lub cev lub cev tuaj yeem dhau NDT, tab sis tom qab ntawd warp 0.08 hli thaum CNC tig vim tias qhov seem seem tsis tau txo qis ntawm casting thiab machining. Ntawm peb qhov chaw ua haujlwm ISO-raws li hauv Qingdao, tib pab neeg ua haujlwm casting, kho cua sov, thiab ntau lub tshuab ua haujlwm. Peb taug qab txhua yam los ntawm tag nrho cov ntaub ntawv traceability - nqis mus rau lub yaj tus naj npawb ntawm cov ntawv pov thawj 316L ingot thiab lub cub tawg lub voj voog cav rau cov tshuaj annealing ntawm 1040 ° C ± 5 ° C.
Qhov kev tswj no tseem ceeb tshaj plaws ntawm cov khoom siv hybrid. Xav txog T800 cobalt-based alloy twj tso kua mis lub hauv paus: cam khwb cia hauv lub plhaub peev, kev daws teeb meem, tom qab ntawd tshuab nrog 5-axis contouring rau mounting nto. Yog tias casting thiab machining tshwm sim ntawm qhov chaw sib cais, thermal keeb kwm tsis sib haum ua rau lub zog tensile tsis sib haum thoob plaws ib feem. Peb cov kev ua haujlwm sib xyaw ua ke ua kom cov txiaj ntsig muaj zog nyob hauv 102-108 ksi thoob plaws txhua daim coupons xeem-txawm tias ntawm 42 kg units nrog 3.2 hli nyias-phab ntsa.
- CNC machined qhov chaw: Tight-tolerance bores (± 0.015 hli) ntawm hardened stainless vaj tse
- Cobalt-nickel alloy Cheebtsam: AMS 5387 nozzles ciaj sia 15,000+ voj voog ntawm 450 ° C
- Hlau castings: Austempered ductile hlau (ADI) iav nqa nrog 1,200 MPa tensile zog
- Hlau thiab stainless hlau castings: ASTM A743 CF8M li qub tuav 200 bar ntawm -40 ° C
Dab tsi "Kev Cai" tiag tiag txhais tau tias hauv kev ua haujlwm siab Casting
"Custom" tau siv tsis raug. Qhov tseeb stainless hlau precision casting Hoobkas tsis tsuas yog luam koj daim duab - nws nyuaj rau kev xav. Thaum cov chaw tsim khoom lag luam Esxias sab hnub tuaj tau xa peb daim duab 304 casting rau kev pabcuam dej hiav txwv, peb qhov kev tshuaj xyuas engineering tau tshaj tawm ob qhov teeb meem: chloride-induced pitting txaus ntshai ntawm weld-kho aav, thiab tsis txaus riser tso rau 110 mm tuab flange. Peb npaj siab hloov mus rau duplex 2205, rov tsim kho lub rooj vag, thiab ntxiv cov tshuaj tom qab vuam annealing. Lub sijhawm ua haujlwm tau nce los ntawm 5 hnub - tab sis kev ua haujlwm tsis ua haujlwm tau nqis los ntawm 7.2% mus rau xoom hla 1,200 units.
Peb validate manufacturability ua ntej tooling. Peb qhov kev txhais GD&T suav nrog kev tshuaj xyuas cov ntaub ntawv muaj txiaj ntsig zoo rau CMM kev soj ntsuam - tsis muaj qhov xav tsis thoob thaum thawj ntu raug tshuaj xyuas. Rau cov geometries uas tsis yog tus qauv zoo li tapered cobalt alloy plugs nrog cov cua txias sab hauv, peb khiav kev simulation, tom qab ntawd tshuab tus qauv qauv ntawm peb DMG MORI NTX 1000, txheeb xyuas cov ces kaum tseem ceeb nrog optical profilometry ua ntej lub plhaub ntau lawm pib.
Saib tom ntej: Qhov twg Precision Casting Tau taub hau
Cov pem hauv ntej tom ntej tsis yog lub qhov cub loj dua - nws yog kev sib koom ua ke ntawm kev ua kom lub cev thiab kev ua haujlwm zoo. Peb tab tom nthuav dav R & D rau hauv cov txheej txheem casting-machining hybrid: tso cov khaubncaws sab nraud povtseg cobalt ncaj qha mus rau hauv cov hlau tsis muaj hlau los ntawm laser hlau deposition, tom qab ntawd ua tiav hauv ib qho kev teeb tsa. Qhov no tshem tawm cov kev sib raug zoo-kab tsis muaj zog hauv cov tsoos cladding. Tib lub sijhawm, peb ntxiv ASME BPVC Tshooj VIII Div. 2 daim ntawv pov thawj kom ua tau raws li qhov xav tau ntawm lub nkoj nruj dua nyob rau hauv European zog ua haujlwm.
Yog tias koj daim ntawv thov xav tau stainless hlau precision casting Hoobkas muaj peev xwm kho metallurgy li engineering - tsis yog kev yuav khoom - koj xav tau cov neeg koom tes uas ntsuas kev ua tiav hauv kev xeem dhau, tsis yog cov khoom xa tuaj raws sijhawm. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. xa cov complex, lub hom phiaj-qhov tseem ceeb qhov chaw uas qhov tseeb qhov tseeb, microstructure tswj, thiab kev ntseeg siab ntawm kev ua haujlwm tsis yog lub hom phiaj sib cais-lawv tau tsim rau hauv txhua kauj ruam txheej txheem.
