Thaum ib tug neeg ntaus 'kev nqis peev casting ze kuv' rau hauv lub tshuab tshawb nrhiav, kuv tau txais nws. Qhov kev xav tam sim no yog hais txog kev xa khoom, cov lus ceev ceev, tej zaum yuav mus ntsib qhov chaw. Tab sis hauv kev lag luam no, qhov sib thooj feem ntau yog qhov nthuav tsawg tshaj plaws ntawm qhov sib npaug. Cov lus nug tiag tiag faus rau hauv qhov kev tshawb fawb no yog hais txog kev nrhiav tus khub uas nkag siab tsis yog lub geometry ntawm ib feem, tab sis lub physics ntawm lub ncuav, chemistry ntawm lub plhaub, thiab qhov tsis muaj kev cuam tshuam ntawm kev tsim khoom. Kuv tau pom ntau qhov haujlwm tsis txaus ntseeg vim qhov kev xaiv tau ua raws li daim ntawv qhia tus pin es tsis muaj peev xwm metallurgical. Wb tham txog qhov koj tab tom nrhiav tiag tiag.
Lub Plhaub Game: Ntau tshaj li qhov sib thooj
Yog li, koj xav tau ib feem. Tej zaum nws yog turbine hniav, ib qho cuab yeej phais, los yog lub twj tso kua mis nyuaj. Koj thawj qhov kev xav yog nrhiav hauv zos. Tab sis 'hauv zos' rau kev nqis peev casting tsis zoo li nrhiav lub khw kas fes hauv zos. Lub vojvoog ntawm lub peev xwm nrhiav tau yog lub tebchaws, txawm tias lub ntiaj teb, rau kev ua haujlwm tshwj xeeb. Tus yuam sij tsis yog lawv tus lej ZIP; nws yog lawv cov txheej txheem tswj. Kuv nco qab ib txoj haujlwm rau cov khoom siv marine hauv 316L stainless. Ib lub khw nees nkaum mais deb tau hais tus nqi zoo heev thiab ncua sij hawm. Lawv qhov chaw tsis muaj dab tsi. Tab sis lawv niaj zaus nchuav ntawm qhov kub thiab txias uas, thaum txuag lub sij hawm rauv, tsim marginal fluidity. Qhov tshwm sim? Ua tib zoo, feeb txias kaw hauv qhov chaw sim tsis muaj kev puas tsuaj. Qhov seem ntsia zoo tag nrho tab sis yuav ua tsis tiav hauv kev ntxhov siab. Lub khw nyob ze, tab sis lawv cov kev coj ua nyob deb ntawm qhov zoo tagnrho.
Qhov no yog qhov kev tshawb nrhiav tiag tiag pib. Koj tsis yog nrhiav xwb peev casting; koj tab tom nrhiav rau lub foundry uas nug txog qhov ua haujlwm, nws cov ntaub ntawv thauj khoom, nws ib puag ncig corrosion. Lawv puas nug koj ntawm cov alloy spec, lossis tsuas yog lees txais tus lej? Ib qho chaw zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), piv txwv li, sau ntau tshaj 30 xyoo hauv plhaub pwm thiab peev casting. Qhov ntev nws tus kheej yog cov ntaub ntawv taw qhia. Hauv kev lag luam no, muaj sia nyob peb xyoos txhais tau hais tias koj tau taug kev booms thiab busts, yoog rau cov hlau tshiab, thiab yuav muaj qhov tob ntawm kev paub tsis meej - yam uas tsis yog nyob rau hauv daim ntawv qhia tab sis yog nyob rau hauv foreman qhov kev txiav txim siab ntawm pre-heat kub rau ib tug cobalt-based alloy.
Lawv lub vev xaib, https://www.tsingtaocnc.com, qhia lawv ntau yam: cam khwb cia hlau, hlau, stainless, thiab cov alloys tshwj xeeb. Qhov ntawd yog lub teeb liab. Kev tuav cov nickel-based alloys tsis yog ib sab gig; nws yuav tsum tau muaj cov khoom siv hluav taws xob tshwj xeeb, cov txheej txheem kev sib kis nruj, thiab kev xav sib txawv. Yog tias ib lub khw teev qhov ntawd, lawv qhia koj tias lawv ua haujlwm hauv qib uas cov khoom siv tsis raug sib tham. Nws hloov qhov 'ze kuv' xam los ntawm thaj chaw mus rau qhov muaj peev xwm sib thooj.
Lub Alloy Maze thiab qhov zoo txaus ntxiab
Hais txog alloys, ntawm no yog ib qho pitfall. Tus tsim qauv qhia Inconel 718 rau nws qhov kev ua haujlwm kub. Ib lub chaw tsim khoom, xav tau kev lag luam tab sis tej zaum tsis muaj kev paub zoo nrog nws, tej zaum yuav qhia tau qib zoo sib xws uas yooj yim dua los nrum. Qee zaum qhov no ua haujlwm. Feem ntau, nws qhia txog kev pheej hmoo. Dab ntxwg nyoog yog nyob rau hauv kev kho cua sov tom qab casting thiab lub resultant theem stability. Kuv kawm qhov no nyuaj heev thaum ntxov nrog lub twj tso kua mis. Peb tau pom zoo rau kev hloov khoom siv uas ua tau raws li cov tshuaj tshwj xeeb ntawm daim ntawv. Nws dhau qhov pib QA. Nws ua tsis tau tejyam nyob rau hauv lub tshav pob tom qab 400 teev ntawm cyclic thermal stress, fracturing raws ib tug grain ciam teb. Lub hauv paus ua rau? Cov hlau hloov pauv cov lus teb rau qhov kev daws teeb meem annealing voj voog txawv, ua rau ntxov ntxov sigma theem nag lossis daus. Lub foundry tsis ncaj ncees; lawv tsuas nyob hauv lawv lub taub hau xwb.
Qhov no yog vim li cas lub tuam txhab tau teev tshwj xeeb tseem ceeb. Thaum QSY qhia meej cov npe cobalt-based thiab npib tsib xee-raws li alloys, nws txhais tau hais tias (los yog yuav tsum qhia) cov txheej txheem tswj rau cov ntaub ntawv nyuaj no. Nws txhais tau tias lawv yuav muaj kev txhawb nqa metallurgical lab, txawm tias outsourced, los xyuas tsis yog chemistry tab sis microstructure. Rau ib tug neeg nrhiav 'peev casting nyob ze kuv', zaj lus qhia yog los soj ntsuam cov ntaub ntawv thov. Nug ib qho kev kho cua sov uas lawv siv rau cov nickel alloy. Nug txog lawv cov nqi seem rau cov khoom ntawd. Cov lus teb yuav qhia koj ntau tshaj qhov ntsuas qhov deb.
Thaum CNC Machining tsis yog qhov kev xav tom qab
Yuav luag tsis muaj peev casting los ntawm tsob ntoo npaj rau nkoj. Muaj kev tshem tawm rooj vag, nto xov, thiab yuav luag txhua zaus, kev ua haujlwm tseem ceeb ntawm datum nta. Qhov no yog qhov uas cov qauv kev sib koom ua ke ntawm ib qho chaw tsim khoom xws li QSY, uas ua ke nrog CNC machining, qhia nws tus nqi. Qhov mob taub hau loj tshaj plaws hauv kev cuam tshuam nrog cov neeg muag khoom sib cais yog kev txhais lus datum. Lub khw casting siv ib txheej ntawm datums rau lawv qhov kev tshuaj xyuas. Lub tshuab khw yuav tsum rov tsim lawv, thiab nyob rau hauv cov txheej txheem ntawd, kev kam rau siab stack-ups tuaj yeem tua ib feem.
Muaj ob txoj hauv kev hauv ib lub ru tsev, lossis tsawg kawg hauv ib qho kev tswj hwm, txo qhov no. Cov kws kho tshuab tuaj yeem tham ncaj qha rau cov kws tsim khoom tsim khoom txog qhov chaw ua haujlwm zoo li-cam khwb cia, qhov chaw porosity kom tsis txhob, thiab cov nyiaj shrinkage. Kuv tau pom cov sij hawm txhuas txiav los ntawm peb lub lis piam los ntawm kev tshem tawm cov khoom xa tuaj, rov hais dua, thiab rov kho lub voj voog ntawm ob lub tuam txhab sib cais. Yog li, koj nrhiav peev casting cov kev pabcuam yuav tsum xav txog cov uas muab kev sib xyaw ua ke. Nws tsis yog yooj yim xwb; nws yog geometric thiab zoo tswj kom zoo dua.
Saib ntawm lawv nplooj ntawv machining. Lawv puas qhia 4-axis lossis 5-axis muaj peev xwm? Rau txoj kev castings xws li impellers lossis turbine hniav, 3-axis machining feem ntau yuav tsis txiav nws (pun npaj). Lub peev xwm ua kom tiav tshuab nyob rau hauv ib qho kev teeb tsa khaws cia cov khoom pov thawj ntawm cov geometry thiab txuag nqi.
Daim Ntawv Quote: Nyeem Ntawm Cov Kab
Koj yuav tau txais ib nqe lus. Nws yuav muaj tus nqi ib thooj, tus nqi siv, thiab lub sijhawm ua haujlwm. Qhov kev sib piv naive yog ntawm peb tus lej. Cov kev paub dhau los yog nyob rau lwm qhov. Ua ntej, saib tus qauv nqi tawg. Puas yog lawv siv cov qauv tsim sai rau cov qauv thawj zaug, lossis cov txheej txheem ib txwm muaj? Rau cov ntim qis, qhov no yog qhov tseem ceeb. Qhov thib ob, saib cov txheej txheem tshuaj xyuas uas tau teev tseg. Puas yog nws tsuas yog luam tawm, lossis lawv puas tau teev cov ntawv tshuaj xyuas thawj zaug, cov ntaub ntawv pov thawj rau ASTM / AMS cov qauv, thiab NDT txoj kev zoo li dye penetrant lossis X-ray? Ib daim ntawv tshuaj ntsuam tsis meej yog tus chij liab.
Kuv nco qab ib qho kev tsocai los ntawm ib lub chaw tsim khoom uas yog 15% pheej yig dua tus tom ntej. Lawv txoj kab tshuaj xyuas tsuas yog hais tias qhov ntsuas qhov ntsuas. Peb mus nrog lawv. Thawj batch muaj zoo meej qhov ntev. Lawv ua tsis tau tejyam nyob rau hauv lub rooj sib txoos vim hais tias cov phab ntsa thickness variation, uas tsis tau hu tawm nyob rau hauv lub luam ntawv raws li ib tug tseem ceeb dimension, yog li ntawd hnyav heev hais tias cov khoom yuav tsis mates. Lub foundry tau ntsib tsab ntawv ntawm qhov tsocai. Peb qhov yuam kev tsis tau hais meej txog qhov xav tau ntawm phab ntsa thickness sib xws hauv cov txheej txheem tshuaj xyuas. Tam sim no, kuv ib txwm thov rau daim ntawv tshuaj ntsuam xyuas tus qauv. Ib tug muaj peev xwm foundry yuav muaj ib tug npaj txhij.
Rau cov khoom siv ntau txheej txheem, cov lus tsocai yuav tsum qhia meej yog tias machining suav nrog, thiab yog tias muaj, mus rau qhov ua tiav. Puas yog ib qho ntxhib machined casting, lossis ib feem tiav? Qhov no clarity cais cov loj players los ntawm cov neeg txiav txim-takers.
Nqa Nws Rov Qab Los Ze Kuv
Yog li, tom qab tag nrho cov no, dab tsi ua 'peev casting nyob ze kuv' txhais tau tias? Nws morphs. Nws dhau los ua tsawg dua ntawm lub cev nyob deb thiab ntau ntxiv txog cov saw hlau resilience, kev sib txuas lus yooj yim, thiab kev sib koom ua ke. Lub chaw tsim khoom nyob rau sab nraud ntawm lub tebchaws nrog pab pawg neeg ua haujlwm stellar thiab kev sib txuas lus digital tsis sib haum (kev tshuaj xyuas CAD meej, cov duab hloov tshiab ntawm cov qauv kev nce qib) tuaj yeem hnov zoo dua li lub khw hauv zos uas nyuaj kom tau txais.
Txawm li cas los xij, kev sib thooj ntawm lub cev muaj ib qho txiaj ntsig tsis tuaj yeem: kev tshuaj xyuas thiab kev sib raug zoo. Muaj peev xwm mus xyuas hauv pem teb, saib cov kab hauv lub plhaub ceramic, hnov cov chaw tsim khoom (qhov chaw tsim khoom zoo muaj qhov tshwj xeeb, tsis kaj siab, tsis hnov tsw - nws tsw ntxhiab ntawm cov txheej txheem tswj), thiab saib tus neeg saib xyuas zoo hauv lub qhov muag yog qhov tseem ceeb. Nws tsim kev ntseeg siab. Qhov no yog qhov chaw uas lub tuam txhab muaj keeb kwm ua haujlwm ntev, zoo li 30-xyoo keeb kwm yav dhau los sau tseg rau QSY, muaj ib daim ntawv ntawm kev ruaj ntseg. Lawv twb nyob ntawd lawm. Tej zaum lawv tau pom tag nrho.
Koj qhov kev tshawb nrhiav, tom qab ntawd, yuav tsum pib nrog kev muaj peev xwm (alloys, txheej txheem, machining), lim los ntawm kev muaj peev xwm ua pov thawj (kev lag luam, cov npe ntawm cov neeg siv khoom, cov lus nug txog kev siv tshuab), thiab tom qab ntawd thaum kawg, siv thaj chaw ua kev sib khi lossis kev xa khoom ntxiv. Lub hom phiaj tsis yog nrhiav tus neeg nyob ze tshaj plaws. Lub hom phiaj yog txhawm rau nrhiav tus khub uas muaj peev xwm tshaj plaws uas tuaj yeem ntseeg tau txhais koj lub hom phiaj tsim rau hauv kev ua haujlwm, cov khoom siv hlau ruaj khov.
