Thaum cov kws tshaj lij hais txog Alloy 4 cov khoom-tshwj xeeb tshaj yog rau cov twj hydraulic, lub siab-siab li qub, lossis cov roj tawm sab nraud thiab cov tshuab hluav taws xob-lawv tsis yog xaj khoom xwb. Lawv tab tom twv ntawm qhov kev ruaj ntseg nyob rau hauv thermal cycling, microstructural kev ncaj ncees tom qab kev kho cua sov, thiab xoom batch-rau-batch variation nyob rau hauv cobalt-nickel alloy teb. Tias yog vim li cas "Alloy 4 Hoobkas" tsis yog lub ntsiab lus tshawb fawb - nws yog lim. Thiab nyob rau hauv Qingdao, ib qho chaw ua haujlwm tsis tu ncua: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD.
Vim li cas Alloy 4 xav tau ntau dua li Casting lossis Machining
Alloy 4-feem ntau hais txog AMS 5387 lossis T800-qib cobalt-based superalloy-tsis yog machined zoo li 304 stainless. Nws ua hauj lwm-hardening tus nqi nce tom qab 10% deformation. Nws thermal conductivity zaum ntawm ~ 12 W / m·K - tsawg dua li ib nrab ntawm txhuas. Standard toolpaths chatter. Cov pa coolants evaporate ua ntej txiav tshav kub dissipates. Peb tau pom cov khw muag khoom pov tseg 60% ntawm thawj lub tog raj kheej lub tog raj kheej vim tias lawv siv cov khoom siv carbide rau Inconel 718, tsis yog AMS 5387's siab dua abrasive hnav tsis kam.
Qhov ntawd yog qhov sib koom ua ke ntsug tseem ceeb - tsis yog kev lag luam jargon, tab sis raws li kev xav tau ntawm lub cev. Ntawm QINGDAO QIANGSENYUAN, casting, kho cua sov, thiab ntau-axis CNC tshwm sim hauv ib lub ru tsev. Tsis muaj kev tuav pov hwm txhais tau tias tsis muaj qhov sib txawv ntawm keeb kwm thermal. Thaum tus neeg siv khoom xa daim duab kos rau cobalt alloy nozzle nrog ± 0.005 hli GD&T callouts ntawm sab hauv taper qhov chaw, pab neeg validates cov khoom nplej txaus * ua ntej * pouring - thiab kho cov tswv yim machining raws li qhov tseeb raws li-cam khwb cia hardness (tsis spec daim ntawv nruab nrab). Qhov no txiav rework ntawm lub lis piam mus rau teev.
Plaub Muaj Peev Xwm Uas txhais tau tias Alloy 4 Kev Npaj
Tsis yog txhua lub khw muag khoom hlau ua haujlwm Alloy 4 ntseeg tau. Nov yog qhov cais qhov muaj peev xwm ua pov thawj los ntawm daim ntawv thov kev thov:
- Material traceability cia mus yaj ntau: Txhua T800 billet nqa tag nrho cov ntawv soj ntsuam-carbon, cobalt, chromium, tungsten, thiab boron cov ntsiab lus pov thawj tiv thaiv ASTM B575. Tsis muaj kev hloov pauv "certified equivalent".
- Thaum tshav kub kub kho synchronization: Cov tshuaj annealing ntawm 1175 ° C ± 5 ° C tsis khiav hauv qhov cub cais tawm ntawm qhov chaw. Nws tau ua raws ncaj qha tom qab kev siv tshuab ntxhib, nrog rau kev tswj cov cua txias uas tau piav qhia txog qhov kawg ntawm qhov geometry - qhov tseem ceeb rau kev zam kom tsis txhob muaj cov theem ntawm sigma embrittlement nyob rau hauv lub twj tso kua mis vaj tse flanges.
- CMM-locked tiav: Thaum kawg OD / ID kam rau ua rau lub piston twj tso kua mis lub tog raj kheej vaj tse raug txheeb xyuas siv Zeiss CONTURA G2 CMMs - nrog rau qhov ntsuas kub-paub qhov ntsuas ntsuas txhua hnub. Tsis yog "cov qauv tshuaj xyuas." Txhua chav.
- Functional validation tshaj qhov ntev: Lub cobalt alloy ntsaws tsis raug tso tawm kom txog thaum nws dhau qhov kev ntsuas hydrostatic siab ntawm 1.5 × ua haujlwm siab rau 30 feeb - tsis muaj xau, tsis muaj yas deformation. Kev tshuaj xyuas qhov muag pom micro-cracks hauv qab 10 × magnification.
Qhov twg Generic Suppliers Fail-Thiab Yuav Ua Li Cas Kev Ua Txhaum Cai yeej
Qee tus neeg yuav khoom xav tias "Alloy 4 = tib cov txheej txheem xws li Hastelloy C-276." Tsis yog. Hastelloy cov cav tov nrog aggressive feeds; Alloy 4 xav tau qis-RPM, siab-torque spindle tswj thiab cryogenic nitrogen txias. Peb ib zaug tau txais kev txiav txim maj nrawm rau AMS 5387 lub hauv paus ncej chais rau lub tshuab hluav taws xob winch-cov neeg siv khoom tau sim peb tus neeg muag khoom. Txhua yam ua tsis tiav ntawm qhov chaw tiav Ra <0.4 µm yuav tsum tau tom qab sib tsoo. Lawv yuam kev? Siv alumina log. Txoj kev daws teeb meem? Pob zeb diamond-plated vitrified log nrog 150 m / s peripheral ceev thiab lub sij hawm lub log hnav-ua hauv tsev.
Qhov no tsis yog theoretical. Nws yog rov ua tau. QINGDAO QIANGSENYUAN txoj haujlwm lean ua haujlwm muab ib tus kws tshaj lij los ntawm kev tshuaj xyuas los ntawm kev xa khoom. Tus neeg ntawd yog tus tswv GD&T txhais lus, taw qhia tias muaj kev cuam tshuam ntawm lub rooj zaum lub kaum sab xis ntawm lub rooj zaum thiab cov ntawv pov thawj-ua ntej pib siv. Tsis muaj silos. Tsis yog "qhov ntawd tsis yog peb chav haujlwm." Tsuas yog ib txoj hauv kev los ntawm kos duab mus rau cov khoom sib khi.
Qhov "Txhim Kho" txhais tau li cas hauv Kev Xyaum—Tsis Yog Cov Lus Cog Tseg
Kev ntseeg siab tsis yog hais txog kev thov ISO 9001. Nws yog hais txog kev xa 127 cobalt alloy nozzles rau North Sea subsea tswj module - raws sijhawm, nrog cov ntaub ntawv pov thawj tag nrho, cov ntaub ntawv qhia txog qhov ntev, thiab cov ntawv ntsuas siab - thiab muaj cov neeg siv khoom rov ua dua li ntawm 48 teev vim tias xoom units yuav tsum tau hloov kho.
Nws tau tsim 210 stainless hlau twj tso kua mis lub hauv paus rau cov neeg Esxias sab hnub tuaj desalination nroj tsuag-txhua tus nrog weld prep grooves machined rau ± 0.15 hli-thaum tswj ≤2% seem hla 18 batch.
Nws txhawb pab pawg R & D nrog cov qauv hloov pauv sai: 72-teev cov lus tsocai, 10-hnub thawj tsab xov xwm, daim ntawv qhia FAI tag nrho-xws li metallurgical cross-sections qhia dendrite caj npab sib nrug hauv peev-cam khwb cia vaj tsev.
Yog tias koj qhov project tom ntej no suav nrog Alloy 4-lossis AMS 5387, T800, lossis ib qho kev sib txawv ntawm cobalt-nickel xav kom tsis muaj kev cuam tshuam ntawm kev ua haujlwm - txoj cai Alloy 4 Hoobkas yuav tsis tsuas yog raws li specs. Nws yuav cia siab tias kev ua tsis tiav hom koj tseem tsis tau ua qauv. Qhov ntawd yog qhov sib txawv ntawm tus neeg muag khoom thiab tus khub.
