Cia peb ua siab ncaj, thaum cov neeg feem coob hnov 'poob ciab casting', lawv pom ib tus kws kos duab zoo nkauj ua tib zoo nchuav cov nyiaj molten rau hauv plaster pwm rau ib daim ntawm cov hniav nyiaj hniav kub. Qhov ntawd tsis yog qhov yuam kev, tab sis nws yog qhov me me, yuav luag romanticized ces kaum ntawm qhov txheej txheem no tiag tiag hauv lub ntiaj teb kev lag luam. Lub sij hawm nws tus kheej, poob ciab hlau casting, los yog ntau yog peev casting, feem ntau tau oversimplified. Qhov kev sib tw tiag tiag tsis yog tsuas yog melting hlau thiab poob cov quav ciab; nws yog hais txog kev tswj tag nrho cov saw hlau - los ntawm thawj cov qauv siv quav ciab mus rau qhov kawg kev kho cua sov - kom ua tiav cov kev ua siab ntev thiab cov khoom siv ncaj ncees uas lwm cov txheej txheem tsis tuaj yeem kov. Nws yog qhov chaw kos duab raws li kev zam txim rau metallurgy.
Lub Wax yog qhov pib, thiab Nws yog mob taub hau
Txhua tus neeg obsesses hla cov hlau, tab sis cov qauv siv quav ciab yog qhov uas koj yeej lossis poob haujlwm. Kev txhaj tshuaj tsis haum rau cov quav ciab - qhov kub thiab txias, siab, lub sijhawm nyob - lawv hais txhua yam. Kub dhau lawm, thiab cov quav ciab shrinks weirdly, ua rau warpage uas tsuas tshwm sim tom qab koj tau ua lub plhaub ceramic. Txias txias heev, thiab koj tau txais qhov tsis zoo saum npoo replication, tej zaum txawm tias cov kab ntws. Kuv tau pom cov khw, cov khoom zoo, khawb tag nrho cov khoom siv vim tias lawv tsis suav nrog cov av noo nyob ib puag ncig cuam tshuam rau cov quav ciab tus cwj pwm hnub ntawd. Nws yog khoom siv nyob, hais ncaj.
Tom qab ntawd koj muaj lub rooj sib txoos rau hauv cov ntoo siv quav ciab. Qhov no yog phau ntawv, kev txawj ua haujlwm. Koj tsis yog tsuas yog gluing qhov chaw ntawm; koj nyob nraum engineering lub rooj vag system. Lub sprue, runners, thiab ingates yuav tsum tau tsim los tso cai rau cov hlau mus sau cov pwm tag nrho thiab directionally solidify kom txo tau shrinkage porosity. Tau txais qhov tsis ncaj ncees lawm, thiab koj yuav muaj qhov zoo nkauj, qhov zoo tshaj plaws castings nrog cov kev tsis zoo sab hauv uas tsis muaj kev ntxhov siab. Kuv nco qab txog qhov project rau lub twj tso kua mis impeller nyob rau hauv duplex stainless hlau uas peb yuav tsum tau reposition lub rooj vag peb zaug kom tshem tawm ib tug tsis tu ncua kub qhov chaw uas ua rau micro-fissures.
Lub sijhawm no yog qhov chaw nrhiav kev paub qw. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog lawv peb xyoo caum hauv qhov kev ua si, yuav muaj qhov no mus rau kev tshawb fawb. Koj tsis tuaj yeem fake hom txheej txheem nco. Nws yog nyob rau hauv lub ntsis ntiv tes ntawm cov neeg ua hauj lwm sib sau ua ke cov ntoo, paub meej npaum li cas wax siv rau ib lub foob tsis tsim ib tug blob uas ruins lub plhaub txheej tom qab. Lawv tsom mus rau lub sij hawm ntev peev casting txhais tau tias lawv yuav pom txhua qhov kev ua tsis tiav hom kev xav.
Tsim lub Plhaub: Daim tawv nqaij Ceramic, Txheej los ntawm Txheej
Lub plhaub-tsev txheej txheem yog deceptively yooj yim rau ntawm daim ntawv: dipped lub ciab tsob ntoo nyob rau hauv ib tug ceramic slurry, stucco nws nrog xuab zeb, cia nws qhuav, rov ua dua. Tab sis dab ntxwg nyoog nyob rau hauv cov ntsiab lus. Lub slurry viscosity yuav tsum tau saib xyuas tas li - nws hloov nrog kub thiab raws li cov khoom evaporates. Thawj lub tsho tiv no, lub ntsej muag lub tsho, yog qhov tseem ceeb tshaj plaws. Nws siv cov hmoov zircon ultra-nplua los yog qee yam zoo ib yam los ntes txhua qhov nthuav dav. Yog tias lub tsho tiv no muaj kab mob los yog siv tsis sib xws, qhov kawg casting nto yuav pitted los yog ntxhib, txawm tias koj ua dab tsi tom qab.
Cov khaubncaws sab nraud povtseg ntxiv dag zog. Koj txav los ntawm cov stucco zoo rau cov ntaub ntawv coarser. Qhov chaw ziab yog qhov tseem ceeb; nrawm dhau thiab lub plhaub tawg los ntawm kev ntxhov siab sab hauv, qeeb dhau thiab koj yuav raug pwm loj hlob lossis sagging. Hauv cov huab cua ntub, qhov no yog kev sib ntaus sib tua tas li. Peb tau siv lub tshuab dehumidifiers 24/7 hauv chav ziab khaub ncaws thaum lub caij monsoon. Txhua txheej yuav tsum tau qhuav kom qhuav ua ntej lub dip tom ntej, txwv tsis pub, koj ntxiab ya raws uas tig mus rau chav thaum lub sij hawm dewaxing thiab tawg lub plhaub ntawm sab hauv tawm. Kuv twb muaj tag nrho lub plhaub tawg nyob rau hauv lub autoclave - ib tug spectacular, kim mess - vim hais tias peb rushed lub ziab ntawm txheej peb.
Qhov kawg plhaub thickness yog kev txiav txim hu. Thicker muaj zog dua rau cov castings loj, tab sis nws kuj txhais tau tias cov khoom siv ntau dua kom sov, cuam tshuam rau cov hlau txias. Rau nyias-walled Cheebtsam, koj xav tau lub plhaub robust txaus los tuav cov hlau dynamic siab tab sis tsis loj heev nws ua rau chilling. Nws yog qhov sib npaug koj kawm los ntawm cov khoom puas.
Dewaxing thiab tua: Lub ntsiab lus tsis rov qab los
Qhov no yog qhov ploj lawm. Koj tsis tuaj yeem rov qab siv quav ciab. Ob txoj hauv kev tseem ceeb yog autoclave (steam) thiab hluav taws kub. Autoclave yog softer ntawm lub plhaub, siv lub zog siab kom yaj thiab tshuab cov quav ciab tawm. Tab sis koj yuav tsum tau sau cov quav ciab - nws yog recyclable, thiab rau lub khw muag khoom loj, uas yog ib qho tseem ceeb ntawm kev txuag nqi. Kev tua hluav taws tsuas yog qhov ntawd: lo lub plhaub rau hauv qhov cub kom hlawv cov quav ciab tawm. Nws nrawm dua, tab sis lub thermal shock tuaj yeem tawg cov plhaub tsis muaj zog, thiab koj poob cov quav ciab.
Tom qab dewaxing, koj nyob nraum nrog ib tug hollow ceramic pwm. Nws zoo li tsis yooj yim, tab sis nws tseem tsis tau raug rho tawm haujlwm. Lub sijhawm tua hluav taws, nyob ib puag ncig 1000 ° C, sinters cov khoom siv ceramic ua ke, tsim kom muaj zog, ruaj khov pwm npaj rau cov hlau. Qhov kev tua hluav taws no tseem hlawv tawm ib qho kawg ntawm cov quav ciab thiab noo noo. Cov pwm yuav tsum tau nchuav thaum nws tseem kub, feem ntau tawm ntawm qhov cub. Ncuav rau hauv pwm txias ua rau ntxov ntxov solidification thiab misruns. Cov logistics ntawm no yog ib tug seev cev - synchronizing lub cub tawg melting cov hlau nrog rau lub cub tawg firing pwm.
Lub ncuav thiab dab tsi los tom qab
Lub ncuav zoo li qhov kawg, tab sis nws dhau hauv vib nas this. Rau cov alloys xws li npib tsib xee los yog cobalt-based superalloys-cov ntaub ntawv QSY npe raws li ib qho tshwj xeeb-qhov chaw yog qhov tseem ceeb. Feem ntau, qhov no yog ua tiav hauv lub tshuab nqus tsev lossis hauv qhov chaw tiv thaiv argon tiv thaiv oxidation. Koj tab tom cuam tshuam nrog cov hlau uas zoo kawg nkaus reactive thaum pouring kub. Ib qho xau me me hauv lub tshuab nqus tsev tuaj yeem ua rau cov khoom siv hluav taws xob puas muaj nqis ntau txhiab.
Ces koj tos. Lub plhaub yuav tsum txias ua ntej koj tuaj yeem tawg tawm. Qhov ntsuas cua txias no yog ib feem ntawm kev kho cua sov rau qee cov alloys. Thaum nws txias, koj tsoo lub plhaub nrog rauj, cov ntxhuav vibratory, lossis txawm tias lub dav hlau dej siab. Dab tsi yog sab laug yog tsob ntoo hlau, koj cov castings faus nyob rau hauv ib tug mess ntawm lub rooj vag thiab khiav. Cov txheej txheem knockout yuav tsum nruj txaus kom tshem tawm cov ceramic tab sis tsis yog nruj heev nws ua rau nyias cov ntu ntu.
Tom ntej no yog txiav tawm. Tshem tawm cov khoom ntawm tsob ntoo yog feem ntau ua nrog abrasive saws lossis tam sim no, feem ntau, CNC bandsaws rau precision. Tom qab ntawd koj tsiv mus rau kev sib tsoo, sandblasting, thiab tiav. Qhov no yog qhov uas ze-net-zoo kom zoo dua ntawm poob ciab hlau casting yeej them tawm. Yog tias koj ua txhua yam zoo, muaj tsawg kawg nkaus cov khoom lag luam tshem tawm. Tab sis yog tias koj tus qauv lossis lub plhaub tau tawm, cov kws ua haujlwm yuav qhia rau koj paub - nrov nrov.
Vim li cas Nws Tseem Tseem Ceeb Hauv Lub Ntiaj Teb CNC
Nrog niaj hnub 5-axis CNC machining muaj peev xwm, cov neeg nug yog vim li cas thab nrog cov txheej txheem txheej txheem ntau kauj ruam. Rau ib-tawm prototypes, lawv yog txoj cai-tsuas yog tshuab nws. Tab sis rau ntim, rau txoj hauv kev geometries (xav tias turbine hniav nrog cov cua txias channel), los yog rau tej yam khoom siv, casting yog unbeatable. Nws tso cai rau cov nplej ntws ua raws li qhov contour, uas tuaj yeem txhim kho lub neej qaug zog. Nws yog feem ntau cov khoom siv-npaum rau cov duab complex dua machining los ntawm cov khoom thaiv.
Thiab rau cov khoom uas yuav tom qab pom precision machining, zoo li ntau qhov chaw uas los ntawm cov chaw muab kev pabcuam tag nrho xws li QSY (lawv qhov chaw https://www.tsingtaocnc.com highlights lawv ua ke casting thiab CNC machining muaj peev xwm), nws ua rau kev nkag siab zoo meej. Koj nrum kom tau qhov yooj yim, complex daim ntawv nrog cov khoom zoo, ces tshuab qhov tseem ceeb mating nto thiab qhov rau nruj tolerances. Nws yog ib txoj hauv kev hybrid uas txhawb nqa lub zog ntawm ob lub ntiaj teb.
Tus nqi tiag tiag ntawm lub hauv paus tsis yog hauv cov khoom siv xwb; nws yog nyob rau hauv kev txawj ntse ntawm yuav ua li cas los ua ke ib tug tsim nrog rau cov khoom thiab cov txheej txheem. Thaum koj pom ib lub tuam txhab uas tau huab cua 30 xyoo, zoo li cov lus qhia rau Qingdao Qiangsenyuan Technology Co., Ltd. qhia, lawv tsis yog muag castings xwb. Lawv tab tom muag qhov kev txiav txim kom tsis txhob muaj qhov pitfalls uas ua rau ib qhov project - hom kev txiav txim uas tsuas yog los ntawm kev kho ntau lub plhaub tawg thiab tshuaj xyuas ntau yam tsis zoo. Qhov ntawd yog qhov koj tab tom yuav tiag tiag nrog tus paub tab peev casting tus khub.
