Thaum koj hnov 'Incoloy alloy qhov chaw', qhov kev xav tam sim ntawd feem ntau dhia mus rau qhov kub thiab txias tsis kam thiab cov kab kos corrosion. Qhov ntawd yog cov lus teb hauv phau ntawv kawm, thiab nws tsis yog qhov tsis yog, tab sis nws yog qhov chaw ua haujlwm tiag tiag - thiab qhov teeb meem tshwm sim - pib. Kuv tau pom ntau qhov haujlwm uas cov khoom tau teev tseg kom raug rau hauv daim ntawv, tab sis qhov tsis ua tiav tau tshwm sim hauv kev txhais lus los ntawm cov ntawv pov thawj zeb uas tau lees paub rau cov khoom siv tau zoo, txhim khu kev qha zaum hauv ib puag ncig kev pabcuam hnyav. Qhov sib txawv ntawm cov alloy lub pedigree thiab ib feem ntawm qhov kev ua tau zoo yog qhov kev paub, los yog tsis muaj nws, tau txais kev phem heev.
Qhov tshwj xeeb hauv cov alloys tshwj xeeb tsis yog kev lag luam xwb
Ua haujlwm nrog Incoloy alloy qhov chaw, tshwj xeeb yog qib xws li 825, 925, lossis 020, txhais tau tias koj tab tom cuam tshuam nrog cov ntaub ntawv uas xav tau kev hwm los ntawm thawj kauj ruam. Nws tsis zoo li machining 304 stainless qhov twg koj tuaj yeem zam me ntsis ntxiv nrog kev pub thiab nrawm. Lub siab nickel thiab chromium cov ntsiab lus uas muab cov alloys lawv zoo heev kuj ua rau lawv tawv, ua hauj lwm-hardening tsiaj nyaum. Kuv nco ntsoov ib pawg ntawm lub cev valve peb tau ua ntau xyoo dhau los; cov cuab yeej yog tus qauv rau high-nickel alloys, tab sis qhov ntxig lub neej yog ze li ntawm ib nrab vim hais tias cov kev kho cua sov tshwj xeeb ntawm cov khoom lag luam bar yog me ntsis tawm ntawm cov qauv. Daim ntawv spec hais tias kev daws teeb meem annealed, tab sis qhov tseeb ntawm lub khw hauv pem teb txawv. Koj kawm ntseeg cov ntaub ntawv, tab sis koj kuj kawm paub tseeb nws nrog thawj txiav.
Qhov no yog qhov kev koom tes nrog lub chaw tsim khoom thiab lub khw muag khoom uas tau txais nws tsis yog kev sib tham. Koj tsis tuaj yeem xa cov ntaub ntawv CAD thiab cov ntaub ntawv hu rau. Piv txwv li, ib lub tuam txhab nyiam Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog lawv peb lub xyoo caum hauv casting thiab machining, feem ntau to taub qhov nuance. Lawv qhov kev paub dhau los plhaub molding, peev casting, thiab CNC machining nrog cov ntaub ntawv zoo li npib tsib xee-raws li alloys txhais tau tias lawv yuav ntsib qhov sib txawv hauv ib qib alloy. Nws yog qhov ua tau zoo, kev paub ntau ntxiv uas hais txog yuav ua li cas lawv mus rau qhov rooj kaw lus rau kev ua haujlwm los yog lub tshuab ua kom txias rau qhov tob tob ntawm lub tshuab ua haujlwm. Nws tsis yog hais txog kev muaj peev xwm; nws yog hais txog muaj cov ntaub ntawv keeb kwm ntawm dab tsi tuaj yeem mus tsis ncaj ncees lawm.
Kev xaiv ntawm casting thiab machining ib feem ntawm cov khoom bar tsis yog ib txwm ncaj nraim, ib yam nkaus. Rau complex geometry, peev casting ntawm Incoloy tuaj yeem ua tau ci ntsa iab, muab cov txiaj ntsig ze-net-zoo li uas txuag tau ib tuj ntawm cov khoom siv kim heev ntawm cov khoom siv nyuaj. Tab sis tom qab ntawd koj tab tom cuam tshuam nrog cov txheej txheem casting tus kheej dab-shrinkage porosity, microstructural sib xws. Kuv tau muaj cov khoom uas dhau los kuaj X-ray tab sis pom tias tsis ua hauj lwm ntxov hauv thermal cycling vim hais tias cov qauv nplej nyob rau hauv ib qho tseem ceeb ces kaum tsis zoo. Nws tsis yog qhov tsis xws luag raws li tus qauv, tab sis nws yog qhov tsis ua haujlwm hauv kev pabcuam. Qee zaum, machining los ntawm cov khoom siv wrought, txawm tias tus nqi, yog qhov kev nyab xeeb dua thawj koom ruam rau cov khoom sib xws, kev kwv yees tau zoo hauv thaj chaw muaj kev ntxhov siab.
Kev Kho Hniav Kub: Theem Ua-los-Tsev Txhua Tus Hais Txog Tab sis feem ntau siv tsis raug
Qhov no yog arguably qhov tseem ceeb tshaj plaws tom qab ua cov kauj ruam rau Incoloy alloy qhov chaw, thiab nws yog qhov uas kuv tau pom cov ntawv nyeem tsis ua tiav. Lub voj voog kho cua sov rau kev ntxhov siab lossis kev daws teeb meem yog qhov tseeb. Ob peb degrees tawm, los yog lub sij hawm ntub dej uas luv me ntsis, thiab koj tsis tau txais tag nrho cov corrosion kuj los yog txhua yam khoom koj them rau. Ib feem yuav zoo tag nrho, dhau qhov kev sim hardness yooj yim, tab sis ua tsis tau zoo nyob rau hauv ib puag ncig chloride-nplua nuj los yog nyob rau hauv creep tej yam kev mob.
Peb kawm qhov no txoj kev nyuaj ntawm ib qhov project rau offshore platform Cheebtsam. Cov ntu tau CNC tshuab zoo nkauj, tab sis kev ntxhov siab tom qab machining tau maj nrawm vim lub sijhawm kaw. Residual stresses, xauv los ntawm nruj machining, tsis tau tshem tawm tag nrho. Hauv kev pabcuam, cov kev ntxhov siab ua ke nrog cov khoom siv sab nraud thiab ib puag ncig ua rau muaj kev ntxhov siab corrosion tawg. Kev soj ntsuam tom qab kev tuag taw qhia square rau qhov kho cua sov nkhaus. Nws tsis yog lub khw tsis ua nws; nws yog tias cov txheej txheem tsis nruj txaus rau qhov tshwj xeeb geometry thiab machining keeb kwm. Tam sim no, peb nyob nraum fanatical txog tsis yog tsuas yog hais txog lub tshav kub kho code, tab sis kuj tham txog ib feem txoj kev mus rau lub cub tawg.
Nov yog lwm qhov chaw kuaj xyuas rau tus neeg xa khoom. Lub khw uas tsuas yog subcontracts kev kho cua sov rau tus nqi qis tshaj yog tus chij liab. Koj xav tau tus khub uas tswj hwm lossis saib xyuas cov txheej txheem no. Saib ntawm QSY cov peev txheej, uas suav nrog ob qho tib si casting thiab tag nrho machining, nws tsim nyog xav tias lawv muaj kev tswj hwm, kev sib koom ua ke rau thermal ua rau lawv. tshwj xeeb alloys. Qhov kev txuas ntxiv ntawm cov hlau molten mus rau qhov ua tiav nyob rau hauv ib lub ru tsev, lossis nyob rau hauv kev tswj xyuas nruj, txo cov kev sib koom ua haujlwm tsis tiav.
Dab ntxwg nyoog yog nyob rau hauv cov ntsiab lus: Vuam, nto tiav, thiab tshuaj xyuas
Nws tsis tshua muaj qhov Incoloy muaj nyob rau hauv kev sib cais. Nws feem ntau yuav tsum tau welded rau lwm yam khoom, thiab qhov no yog ib qho tshwj xeeb ntawm nws tus kheej. Siv cov khoom siv hlau tsis raug lossis tiv thaiv cov roj, lossis kev kho cua sov ua ntej / tom qab vuam tsis raug, tuaj yeem tsim qhov tsis muaj zog, corrosion-nruab thaj tsam ntawm koj lub super alloy. Kuv ib txwm hais rau cov txheej txheem vuam tsim nyog (WPS) rau qib thiab daim ntawv thov, thiab feem ntau ntawm daim coupon xeem los ntawm cov khoom siv tib yam.
Tom qab ntawd muaj nto tiav. Lub tshuab ua tiav saum npoo rau lub ntsej muag sealing yog qhov sib txawv ntawm ib qho rau txoj kev kub-kub. Rau kev siv corrosion, qee zaum ib qho chaw deg thiab passivated tau teev tseg, tab sis cov txheej txheem yuav tsum tau ua kom haum rau cov nickel-chromium-molybdenum alloys xws li Incoloy 625, tsis yog cov txheej txheem stainless nkaus xwb. Peb ib zaug tau muaj cov khoom xa rov qab vim yog cov xeb hlau sab saum toj - tig tawm cov tshuaj tiv thaiv passivation yog nruj heev rau cov ntsiab lus molybdenum tshwj xeeb, ua rau xaiv etch es tsis yog txheej tiv thaiv.
Thaum kawg, kev tshuaj xyuas. Dimensional checks yog muab. Tab sis rau qhov tseem ceeb Incoloy alloy qhov chaw, koj tab tom saib PT / MT rau qhov tsis xws luag, RT lossis UT rau lub suab sab hauv, thiab feem ntau PMI (Positive Material Identification) txhawm rau txheeb xyuas cov qib alloy ntawm lub rooj vag, tus khiav, thiab qhov nws tus kheej. Mix-ups tshwm sim. Kuv tau pom ib lub pallet ntawm Incoloy 825 tig los ua 316L vim tias ib daim ntawv tau pauv ntawm lub tsev khaws khoom. PMI nrog ib tug handheld XRF phom ntes nws ua ntej cov khoom mus rau hauv ntau lawm. Nws yog ib qho yooj yim kos uas txuag monumental mob taub hau.
Tus nqi vs. Tus nqi: Tus lej nyob mus ib txhis
Incoloy tsis pheej yig. Tus nqi ntawm cov khoom siv raw yog siab, kev ua tiav yog xav tau, thiab kev tshuaj xyuas yog nruj. Nws yog kev ntxias kom nrhiav kev txuag nqi, tab sis qhov no yog qhov classic koj tau txais yam koj them rau tus sau. Xaiv tus neeg muag khoom nkaus xwb ntawm tus nqi tsev yog ib txoj hauv kev nrawm rau cov teeb meem kev ntseeg siab. Tus nqi tsis nyob hauv qhov pheej yig tshaj; nws yog nyob rau hauv ib feem uas kav lub neej tsim nyob rau hauv ib tug rau txim daim ntawv thov yam tsis ua hauj lwm.
Tus nqi-txuag tiag tiag tshwm sim hauv kev tsim rau kev tsim khoom (DFM) kev sib tham thaum ntxov. Lub vojvoog puas tuaj yeem nce ntxiv me ntsis txhawm rau txhim kho cov txiaj ntsig casting thiab txo qis kev ntxhov siab? Kev kam rau siab tuaj yeem txo tau los ntawm ± 0.05mm txog ± 0.1mm yam tsis muaj kev cuam tshuam rau kev ua haujlwm, txuag lub sijhawm ua haujlwm loj ntawm cov khoom siv tawv? Ib tus khub tsim khoom zoo, zoo li qhov tau piav qhia ntawm https://www.tsingtaocnc.com, yuav tsum koom nrog cov kev sib tham no. Lawv lub sijhawm ua haujlwm ntev qhia tias lawv tau pom cov qauv tsim txaus los muab cov tswv yim DFM cov tswv yim uas ua kom zoo rau ob qho tib si kev ua haujlwm thiab tus nqi, tsis yog tsuas yog luam tawm thiab hais tawm.
Qee zaum, qhov kev txiav txim siab yog siv cov khoom siv qis dua nrog cov qauv tsim muaj zog dua lossis kev tiv thaiv ntxiv (xws li cov txheej txheem). Tab sis thaum qhov kev pab cuam ib puag ncig-hais, flue gas desulfurization systems, qaub roj qhov dej, los yog high-temperature thermal processing-thov Incoloy, tsis muaj ib qho kev hloov. Tom qab ntawd, kev tsom mus rau kev ua tiav cov fabrication flawlessly. Kev nqis peev yog nyob rau hauv kev tiv thaiv unscheduled downtime, uas dwarfs tus nqi pib.
Saib Rov Qab thiab Mus Rau Tom Ntej
Xav txog ob xyoo caum nyob ib ncig ntawm cov ntaub ntawv no, cov evolution tau hloov maj mam tab sis tseem ceeb. Alloy compositions tau tweaked rau kev ua tau zoo dua, thiab kev tsim khoom zoo li CNC machining thiab kev sim tsis muaj kev puas tsuaj tau dhau los ua qhov tseeb dua. Txawm li cas los xij, cov teeb meem tseem ceeb tseem nyob: nkag siab txog cov khoom siv tus cwj pwm dhau ntawm daim ntawv teev cov ntaub ntawv, hwm txhua kauj ruam ntawm cov txheej txheem, thiab tsis txhob xav tias tus txheej txheem txheej txheem yuav tau txais txiaj ntsig zoo.
Qhov kev ntseeg siab tshaj plaws Incoloy alloy qhov chaw Kuv tau pom los ntawm kev sib koom tes qhov twg engineering, kev yuav khoom, thiab kev tsim khoom sib koom ua ke, thiab qhov twg tus neeg muag khoom raug kho raws li kev sib koom tes. Nws yog hais txog kev sib koom tag nrho cov ntsiab lus ntawm kev pabcuam - qhov kub thiab txias, kev sib xyaw ntawm cov ntaub ntawv, cov ntaub ntawv thauj khoom - yog li lawv tuaj yeem siv lawv cov txheej txheem kev paub zoo. Nws hloov los ntawm kev sib pauv kev sib raug zoo mus rau ib tus kws pab tswv yim.
Thaum kawg, nws npau taws rau qhov no: qhia Incoloy yog kev tshawb fawb, tab sis ua kom tiav Incoloy tivthaiv yog khoom siv tes ua. Nws yuav tsum muaj kev sib xyaw ntawm kev paub txog metallurgical, kev paub hauv khw hauv pem teb, thiab kev saib xyuas tsis tu ncua kom nthuav dav. Cov tuam txhab uas tau ua nws tau ntau xyoo, dhau los ntawm kev ua tiav ntawm kev ua tiav thiab cov kev kawm mob uas tau kawm, yog cov uas hloov cov kev ua tau zoo ntawm kev ua haujlwm siab rau hauv qhov kev ua haujlwm siab uas koj tuaj yeem nyob ntawm. Qhov ntawd yog qhov txawv ntawm ib feem uas ua tau raws li kev luam tawm thiab ib feem uas muaj sia nyob hauv lub ntiaj teb tiag.
