Thaum cov engineers aerospace xav tau turbine blades uas tuav ± 0.05 mm kam rau ua ntawm 1,200 ° C - lossis cov roj nozzles uas muaj sia nyob 30,000-teev kev pabcuam nyob tsis muaj microcrack propagation - lawv tsis pib nrog cov lus pom zoo. Lawv pib nrog tus cwj pwm ntawm cov khoom siv, keeb kwm thermal, thiab qhov ruaj khov ntawm qhov ntev ntawm kev kho cua sov. Yog vim li cas peev casting aerospace Hoobkas kev koom tes tsis tshua muaj kev vam meej ntawm catalog specs ib leeg. Lawv pob khawm ntawm kev qhuab qhia metallurgical, kev ua kom pom tseeb, thiab kev ua haujlwm ntawm tes nrog cov hlau zoo li AMS 5387 cobalt-chromium thiab T800-qib superalloys-cov ntaub ntawv uas tiv thaiv kev ua haujlwm tab sis xav tau ze-net-shape precision.
Peb tau pom ntau qhov haujlwm tsis txaus ntseeg vim tias lub tsev casting tau kho cov khoom siv dav hlau raws li "tsuas yog lwm txoj haujlwm siab ntev." Ib tus neeg siv khoom AMS 5387 lub twj tso kua mis lub tsev tsis ua tiav kev ntsuas kev vibration - tsis yog los ntawm cov qauv tsim, tab sis los ntawm cov qauv tsis sib xws ntawm cov khoom siv. Lub hauv paus ua rau? Ib tus neeg muag khoom uas tau txais cov khoom nyoos cobalt-nickel ingots yam tsis muaj ntawv pov thawj batch-theem, ces hla kev daws teeb meem annealing pov thawj. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho txhua qhov aerospace casting raws li cov txheej txheem thermomechanical-tsis yog cov duab hauv hlau. Peb qhov chaw ua haujlwm ISO-raws li Qingdao khiav tag nrho-lub voj voog peev casting: wax qauv sib dhos, ceramic plhaub tsev, dewaxing, nqus-tswj firing, precision pouring nyob rau hauv argon, thiab tom qab cam khwb cia kub kho nrog real-time thermocouple logging. Tsis muaj kauj ruam yog outsourced. Tsis muaj ntaub ntawv ntau poob traceability.
Dab tsi cais qhov kev lag luam aerospace-muaj peev xwm ua lag luam los ntawm lub hom phiaj dav dav tsis yog cov cuab yeej siv xwb - nws yog qhov nruj npaum li cas kev sib koom ua ke nrog cov txheej txheem hauv qab. Peb tshuab 72% ntawm peb cov aerospace castings hauv tsev siv 5-axis CNC chaw calibrated txhua hnub rau ISO 10360-2. Vim li cas qhov ntawd tseem ceeb? Vim hais tias ib tug cobalt alloy valve lub cev cam khwb cia rau ± 0.3 hli tsis tuaj yeem ua tiav ± 0.025 hli zaum kawg ID kam rau ua tshwj tsis yog tias lub tshuab ua haujlwm tau siv tib lub datum nto tsim thaum lub plhaub pwm sib dhos. Peb cov engineers co-tsim casting rooj vag thiab risers * nrog * qhov kawg machining ib ntu hauv siab - tsis yog tom qab qhov tseeb. Piv txwv li, thaum tsim cov piston twj tso kua mis lub tog raj kheej vaj tse rau hydraulic actuation systems, peb tso feeders kom txo cov residual kev nyuaj siab nyob rau hauv lub bore phab ntsa, ces tshuab sab hauv splines siv kev cai-hauv av carbide cov cuab yeej uas phim li-cam khwb cia nto hardness profile. Qhov kev sib koom ua ke no txiav cov khoom seem los ntawm 41% ntawm thawj tsab ntawv tsim piv rau cov khw uas casting thiab machining ua haujlwm raws li cov chaw ua haujlwm.
Qee tus yuav sib cav hais tias xuab zeb casting muaj kev hloov pauv sai rau cov qauv dav hlau loj. Tab sis rau nyias-walled, complex geometries-zoo li turbine shroud ntu los yog combustion chamber liners- peev casting tseem irreplaceable. Xuab zeb pwm tawm tsam nrog phab ntsa thicknesses hauv qab 4 hli; ceramic plhaub kov 1.8 hli tsis tu ncua. Qhov tseem ceeb tshaj, xuab zeb casting qhia txog silica suav nrog kev pheej hmoo uas cuam tshuam lub neej qaug zog hauv cov khoom sib hloov. Peb tau lees paub txhua lub plhaub aerospace batch ntawm X-ray tomography - tsis yog radiography - thiab tsis lees paub cov kab noj hniav tshaj ASTM E192-22 Theem 2 porosity. Xyoo tas los, ob tus neeg siv khoom tau hloov pauv los ntawm cov chaw muag khoom nyob sab Europe tom qab pom rov ua dua subsurface oxide zaj duab xis hauv lawv cov cobalt alloy nozzles. Peb cov txheej txheem siv lub tshuab nqus tsev degassing ua ntej ncuav thiab tswj cov cua txias hauv qab 100 ° C / teev los ntawm gamma-prime solvus-tawm cov yeeb yaj kiab tag nrho.
Aerospace buyers tsis yog xav tau cov khoom xwb. Lawv xav tau cov ntaub ntawv pov thawj: cov ntaub ntawv pov thawj nrog tag nrho cov tshuaj ntsuam xyuas hluav taws xob, CMM cov ntawv ceeb toom khi rau GD&T callouts ntawm ASME Y14.5 daim duab kos, cov ntaub ntawv kho cua sov stamped los ntawm cov ntawv pov thawj metallurgists, thiab cov ntaub ntawv tsis muaj kev puas tsuaj traceable rau NADCAP AC7108 Rev. F. ruaj ntseg portal qhov twg cov neeg muas zaub saib nyob soj ntsuam raws li txoj cai, download tau ntawv pov thawj cov ntaub ntawv, thiab taug qab qhov seem sib txawv ntawm SPC tswj kab kos. Rau kev tsim kho sai sai, peb nthuav tawm lub voj voog los ntawm kev kos duab tso tawm rau thawj tsab xov xwm xa mus rau 14 hnub ua haujlwm - yam tsis tau hla lub plhaub ziab lub sij hawm los yog txo cov tshuaj annealing tuav. Qhov kev ceev ntawd yog los ntawm kev tsim qauv tsim qauv, tsis muaj kev cuam tshuam cov txheej txheem.
Yog tias koj qhov kev tiv thaiv aerospace tom ntej xav tau AMS 5387 cobalt alloy, T800-raws li geometry, los yog siab-rated stainless hlau castings nrog rau qhov chaw ua haujlwm xav tau Ra ≤0.4 µm - peb tsim lawv ua, tsis yog dhau. Tsis yog raws li cov khoom tawm ntawm lub txee, tab sis raws li cov tshuab tsim ua haujlwm hauv cov txheej txheem rov ua dua, sau tseg, thiab cov txheej txheem metallurgically lav. Mus ntsib https://www.tsingtaocnc.com los tshuaj xyuas cov peev txheej, thov cov ntaub ntawv xeem cov ntaub ntawv, lossis teem sijhawm kev tshuaj xyuas engineering nrog peb pawg neeg ua haujlwm casting. Precision nyob rau hauv aerospace pib ntev ua ntej lub ncuav-thiab nws xaus nkaus xwb thaum txhua qhov loj me, microstructure, thiab nto ua haujlwm raws li lub hom phiaj tseem ceeb ntawm lub davhlau.
