Thaum engineers xav tau ib ceev qauv peev casting Hoobkas uas xa cov khoom siv hlau ua haujlwm nyob rau hauv 15 hnub - yam tsis muaj ASTM lossis ISO-certified cov ntaub ntawv kev ncaj ncees - lawv tsis nrhiav "sai casting" thiab pib tswj cov txheej txheem. Peb tau pom nws ntau zaus: lub twj tso kua mis North American OEM xa GD & T-hnyav AMS 5387 cobalt alloy nozzle kos duab, cia siab tias yuav siv sijhawm 3 lub lis piam. Feem ntau cov foundries teb nrog "6-8 lub lis piam, raws li kev pom zoo rau tus qauv." Ib tus neeg siv khoom tau hais rau peb tias: * "Peb twb tau tso tseg ob nqe lus ua ntej peb pom cov pab pawg uas nug txog peb cov txheej txheem ntsuas siab - tsis yog peb tus lej PO xwb."*
Pab neeg ntawd yog QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Raws li nyob rau hauv Qingdao, Tuam Tshoj, lawv ua hauj lwm ib tug ISO-raws li qhov chaw uas peev casting tsis yog ib tug standalone kev pab cuam - nws yog ib tug ntawm ib tug nruj nreem kaw system uas muaj xws li CNC machining, kev kho cua sov, CMM-raws li nyob rau hauv-txoj kev soj ntsuam, thiab tag nrho cov ntaub ntawv traceability. Lawv tsis kho cov qauv ua "kev zam me me." Lawv kho lawv raws li qhov kev lees paub siab ua haujlwm - qhov twg txhua qhov microstructure lis, txhua qhov chaw tiav Ra tus nqi, thiab txhua qhov sib txawv ntawm qhov sib txawv tau nkag mus, tshuaj xyuas, thiab sib cuam tshuam rov qab rau qhov ntsuas qhov ntsuas.
Nov yog qhov ua rau lawv sib nrug - tsis yog hauv kev lag luam, tab sis hauv kev ntsuas tau:
- Alloy kev qhuab qhia, tsis yog alloy ntau yam. Lawv tshwj xeeb hauv plaub tsev neeg: cobalt-nickel superalloys (T800, AMS 5387), stainless hlau (CF8M, F22), ductile hlau (ASTM A), thiab cov hlau tsis tshua muaj hlau. Tsis muaj "peb pov dab tsi" thov. Hloov chaw: sau tseg lub zog tensile tuav tom qab HIP + tshuaj annealing ntawm T800 nozzles; repeatable hardness profiles hla 120-mm-tuab piston twj tso kua mis lub tog raj kheej nyob; xoom batch rejection ntawm cobalt alloy plugs kuaj ib ASTM E112 grain loj qauv.
- Casting-to-machining handoff tshwm sim hauv ib lub qhov rooj zoo. Tsis zoo li cov khw muag khoom uas muaj kev ua tiav lossis kev kho cua sov, lawv txoj kev sib xyaw ntsug txhais tau tias tib tus CMM tus neeg teb xov tooj uas txheeb xyuas lub plhaub tuab ua ntej ncuav kuj tseem txheeb xyuas qhov kawg ID / OD concentricity tom qab machining. Qhov ntawd tshem tawm kev ua siab ntev los ntawm cov neeg muag khoom sab nraud-thiab piav qhia vim li cas lawv lub siab lub cev valve ua tiav ± 0.015 hli phab ntsa tuab sib xws thoob plaws 300+ units, tsis yog thawj tsib.
- Prototyping txhais tau tias kev koom tes hauv engineering - tsis yog ib feem ntawm kev xa khoom. Thaum ib lub tuam txhab European hydraulic xa cov khoom tsis zoo ntawm lub tshuab winch shaft roller nrog asymmetric txias fins, pab pawg tsis tau hais tias "yog" lossis "tsis yog." Lawv tau khiav thermal simulation ntawm tus qauv siv quav ciab, kho qhov rooj kom tiv thaiv kom tsis txhob muaj qhov porosity hauv lub hauv paus fin, thiab tau npaj ib lub voj voog hloov kev ntxhov siab ua ntej ua haujlwm ntxhib. Tus qauv dhau qhov kev sim tawg ntawm 1.5 × qhov ntsuas siab - ntawm thawj zaug sim.
Qee tus yuav sib cav hais tias qhov nrawm cuam tshuam rau kev ntseeg siab ntawm metallurgical. Tab sis cov ntaub ntawv tiag tiag hauv ntiaj teb contradicts qhov ntawd. Nyob rau hauv 2023, QINGDAO QIANGSENYUAN tsim 87 ceev-turnaround peev castings rau roj & roj downhole cuab yeej. Txhua feem nqa tag nrho cov cua sov ntau traceability, ntawv pov thawj zeb xeem ntawv qhia, thiab thib peb-tog PMI pov thawj. Zero Cheebtsam ua tsis tiav thaum lub sijhawm cov neeg siv khoom tsim nyog. Vim li cas? Vim tias lawv qhov kev ua haujlwm "ceev" pib nrog cov khoom siv-cov ntaub ntawv pov thawj raw khoom tsuas yog los ntawm cov neeg muag khoom tau soj ntsuam rau EN 10204 3.1 cov qauv-thiab xaus nrog kev ua haujlwm, tsis yog cov ntaub ntawv.
Lawv tsis zais cov kev txwv. Kev nqis peev casting ua tau zoo rau cov geometry nyuaj-tab sis tsis tuaj yeem sib tw CNC rau cov yam ntxwv hauv qab 0.3 hli lossis cov qauv tsis muaj cov xov sab hauv. Lawv cov engineers chij thaum ntxov. Thaum kuaj xyuas kos duab, lawv yuav hais kom ntxiv 0.5 ° cov cua ntsawj ntshab mus rau qhov chaw nres nkoj nyias-walled lossis hloov mus rau hauv cov khoom siv rau qhov tseem ceeb sealing nto. Qhov ntawd tsis yog upselling. Nws tiv thaiv $ 12,000 hauv rework thaum thawj pwm teeb tuaj txog.
Qhov no txhais li cas rau koj qhov project tom ntej? Yog tias koj qhov yuav tsum tau ua kom nruj rau ntawm cov ntu nyias, kev tiv thaiv corrosion nyob rau hauv cov cheeb tsam uas muaj chloride-nplua nuj, los yog qaug zog kev ua haujlwm nyob rau hauv cyclic loading-thiab koj xav tau lub cev validation nyob rau hauv ≤12 hnub ua hauj lwm-ces ib ceev qauv peev casting Hoobkas nrog embedded metallurgical nruj teeb meem ntau tshaj tus nqi qis tshaj. QINGDAO QIANGSENYUAN daim ntawv qhia hnub ntau lawm qhia 92% raws sij hawm xa tuaj rau cov qauv xaj xa tawm thoob ntiaj teb xyoo 2024. Lawv cov phiaj xwm lean tsis caum ntim. Nws tiv thaiv lub sij hawm muaj tseeb-los ntawm kev tsim tsis rau hauv cov txheej txheem validation, tsis shipping hnub.
Saib ua ntej, lawv qhov R & D tsom xam yog nqaim: hybrid casting-machining workflows rau high-alloy Cheebtsam uas nyob ze-net duab txo lub sij hawm machining los ntawm 40% yam tsis muaj kev cuam tshuam lub neej qaug zog. Lawv tab tom nthuav dav AMS 5387 cov txheej txheem qhov rais rau qhov loj-section twj tso kua mis vaj tse thiab validating tshiab ceramic plhaub formulations rau finer nto finishes ntawm cobalt nozzles. Tsis yog vim nws suab zoo nkauj - tab sis vim tias cov neeg siv khoom thov rau nws.
Ceev tsis ruaj khov yog suab nrov. Precision tsis muaj repeatability yog hmoov. A ceev qauv peev casting Hoobkas tau txais kev ntseeg siab thaum nws xa cov khoom uas ua haujlwm - tsis yog tuaj txog. Qhov ntawd yog tus qauv QINGDAO QIANGSENYUAN ntsib, tsis tau cog lus tseg.
