Thaum cov kws ua haujlwm qhia txog cobalt-nickel alloy qhov chaw rau hydraulic twj lossis lub siab-siab li qub, lawv tsis yog yuav cov khoom siv xwb-lawv tab tom ua haujlwm ruaj ntseg, kev nyab xeeb margins, thiab kev tswj xyuas cov nqi mus sij hawm ntev. Ib qho me me me me nyob hauv AMS 5387 twj tso kua mis vaj tse tuaj yeem ua rau qhov ua tsis tau zoo: kev sib tsoo ntawm 3,000 psi, hnav ntxov ntxov hauv piston bores, tsis npaj kaw hauv cov roj av sab nrauv. Tias yog vim li cas muab los ntawm qhov tseeb alloy qhov chaw Hoobkas-ib qho uas masters metallurgy * thiab * machining - tsis yog casting lossis milling - yog tsis sib tham.
Vim li cas Kev Txawj Ntse Ua Ntej - Tsis Kawg
Peb tau pom ntau txoj haujlwm kaw thaum cov neeg muag khoom kho T800 cobalt-based alloy li "tsuas yog lwm cov hlau tsis huv." Nws tsis yog. Nws thermal conductivity yog 1/5 ntawm 316 stainless. Nws ua hauj lwm-hardening tus nqi spikes tom qab 15% cov ntaub ntawv tshem tawm. Standard toolpaths pob txha inserts; Cov kev kho cua sov ua rau cuam tshuam qhov tseem ceeb GD&T callouts. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., cobalt-nickel tsis yog cov khoom siv-nws yog cov txheej txheem txwv peb ua haujlwm ib puag ncig. Lawv pab neeg niaj hnub hloov kho tus nqi pub khoom nruab nrab ntawm kev ua haujlwm raws li lub sijhawm tiag tiag cov cuab yeej-hnav tawm tswv yim los ntawm kev tshawb nrhiav. Lawv pre-heat pwm rau 220 ° C ua ntej pouring AMS 5387-txiav micro-shrinkage los ntawm 40% piv rau ambient casting. Qhov no tsis yog kev paub theoretical. Nws yog qhov sib txawv ntawm lub nozzle muaj sia nyob 18 lub hlis hauv kev pabcuam roj qaub-thiab ua tsis tau rau lub hli rau.
Vertical Integration Uas ua tau kom ruaj khov
Cov neeg muag khoom feem ntau outsource casting, machining, lossis xov. Qhov ntawd tsim peb qhov kev sib tw, peb qhov sib txawv ntawm qhov tsis sib xws, thiab peb lub sijhawm rau kev sib tw. QINGDAO QIANGSENYUAN ua haujlwm nyob rau hauv ib lub ru tsev: peev-cam khwb cia cobalt nozzles ncaj nraim mus rau 5-axis CNC chaw rau bore honing, ces mus rau lub tshuab nqus tsev kub-kho qhov cub calibrated txhua hnub tiv thaiv NIST-traceable thermocouples. Tsis muaj lwm tus neeg muag khoom rov ua haujlwm CMM cov ntawv ceeb toom. Tsis muaj batch raug tso tawm yam tsis muaj daim ntawv pov thawj cov ntaub ntawv pov thawj - nqes mus rau daim ntawv ntsuam xyuas zeb (MTR) cov lej nkag rau txhua ntu ID. Thaum ib tus neeg siv khoom nyob sab Europe tau thov ± 0.005 hli roundness ntawm 320-mm-inch piston twj tso kua mis lub tog raj kheej vaj tse, pab pawg tsis tau thov kom zam qhov sib txawv. Lawv tau hloov kho lub voj voog kev ntxhov siab, ntxiv qhov kev sib tw thib ob nrog cov khoom siv ceramic, thiab tuav cov spec - ntawm thawj kab lus.
Qhov twg "Kev Cai" txhais tau tias ua haujlwm-tsis yog qhov loj me xwb
"Kev cai" feem ntau txhais tau tias "tsis yog tus qauv kos duab." Ntawm no alloy qhov chaw Hoobkas, nws txhais tau hais tias kev daws teeb meem ua ntej. Rau lub tshuab hluav taws xob tsheb winch center ncej rau cov menyuam, tus neeg siv tau teev cov hardness-tab sis tsis nto compressive residual stress. Pab pawg tau khiav FEA simulations, npaj txhaj tshuaj-peening tom qab machining, thiab validated fatigue life extension los ntawm 2.3x piv rau untreated kuaj. Rau cobalt alloy plugs siv nyob rau hauv subsea valve manifolds, lawv hloov txheem Ra 0.8 µm tiav nrog electropolished Ra 0.2 µm-txo cov tshuaj chloride pitting pib kev pheej hmoo los ntawm 70% hauv ASTM G48 xeem. Cov no tsis yog add-ons. Lawv tau ci rau hauv cov lus hais, PPAP, thiab cov txheej txheem soj ntsuam zaum kawg.
Kev xa tawm tiag tiag - Tsis yog Lub Sijhawm Ua Haujlwm Zoo
Cov lus cog tseg rau lub sijhawm ua haujlwm txhais tau tias tsis muaj dab tsi yog tias thawj cov khoom xa tuaj tuaj nrog MTRs tsis sib haum lossis tsis muaj ntaub ntawv kho qhov vuam. QINGDAO QIANGSENYUAN siv lean ntau lawm npaj-tsis yog kanban boards, tab sis dynamic teem sij hawm khi rau raw khoom muaj ntau. Thaum tus neeg siv khoom North American xav tau 42 lub siab li qub hauv 11 lub lis piam rau kev hloov pauv hloov pauv, pab pawg tau kaw hauv cobalt-nickel ingot xa * ua ntej * quoting - tom qab ntawd ua ntu zus casting, ntxhib machining, kev kho cua sov, thiab ua tiav dhau ntawm cov chaw ua haujlwm sib koom kom tsis txhob muaj kev ncua sijhawm. Txhua feem nqa tag nrho traceability: yaj tooj, rauv ID, CMM tus neeg teb xov tooj, txawm coolant batch code. Tsis muaj kev zam. Tsis yog "qhov no nyob ze txaus."
Rau lub hom phiaj tseem ceeb ntawm cov khoom siv hlau, kev ntseeg siab tsis yog kev lag luam thov - nws yog qhov tshwm sim ntawm kev qhuab qhia metallurgical, kev tswj cov txheej txheem sib xyaw, thiab xoom kam rau ua haujlwm tsis meej. Yog tias koj qhov project tom ntej no suav nrog AMS 5387, T800, lossis ib qho kev ua haujlwm siab uas tsis ua haujlwm tsis yog qhov kev xaiv, pib nrog tus khub uas nws lub ntsiab lus ntawm "kev cai" pib nrog cov khoom coj cwj pwm - thiab xaus nrog koj lub cev ua haujlwm, nyab xeeb, raws sijhawm. Qhov ntawd yog qhov ntsuas rau qhov tseeb alloy qhov chaw Hoobkas.
