Cov Txheej Txheem Casting Hlau
Kev ua hlau yog ib qho ntawm cov txheej txheem tsim khoom qub tshaj plaws, tau siv rau ntau txhiab xyoo. Cov txheej txheem no tso cai rau kev tsim cov khoom siv hlau hauv cov duab nyuaj thiab ntau qhov ntau thiab tsawg. Qhov tseem ceeb, kev ua hlau yog kev yaj hlau, nchuav cov kua rau hauv pwm, thiab cia nws khov thiab tawv. Tsab xov xwm no yuav piav qhia txog cov kauj ruam tseem ceeb hauv cov txheej txheem ua hlau.
1. Kev Tsim Qauv
Kauj ruam thawj zaug hauv cov txheej txheem casting hlau yog kev ua qauv. Ib qho qauv yog ib qho qauv lossis daim ntawv theej ntawm cov khoom uas yuav tsim tawm. Cov qauv no feem ntau yog me ntsis loj dua li cov khoom xav tau los them rau kev ntswj hlau thaum nws khov. Cov qauv tuaj yeem ua los ntawm cov ntaub ntawv xws li ntoo, yas, lossis hlau.
Kev Ua Qauv Ntoo
Cov qauv ntoo feem ntau yog cov uas pom ntau vim lawv yooj yim rau kev ua duab thiab pheej yig. Txawm li cas los xij, cov qauv ntoo muaj qhov tsis zoo ntawm kev tsis ruaj khov thiab tuaj yeem khoov vim yog dej noo.
Kev Tsim Qauv Yas thiab Hlau
Cov qauv yas thiab hlau ruaj khov dua thiab meej dua, tab sis kim dua thiab siv sijhawm ntev dua los ua.
2. Ua Cov Pwm Xuab Zeb
Thaum tus qauv ua tiav lawm, kauj ruam tom ntej yog ua ib lub pwm xuab zeb. Lub pwm xuab zeb yog ib lub thawv siv los tuav cov hlau uas yaj kom txog thaum nws khov thiab tawv raws li tus qauv.
Hom Moulding Sand
Cov xuab zeb siv rau pwm yuav tsum ua tau raws li qee yam qauv, xws li cov dej noo, lub zog, thiab lub peev xwm los tswj nws cov duab thaum cov hlau yaj raug nchuav rau hauv. Cov hom xuab zeb feem ntau yog xuab zeb silica nrog cov organic lossis inorganic binders lossis adhesives.
Cov txheej txheem ua pwm xuab zeb
1. Kev Npaj Qauv: Tus qauv raug muab tso rau hauv lub thawv pwm (lub raj mis).
2. Kev Sau Xuab Zeb: Cov xuab zeb molding raug nchuav thiab compacted nyob ib ncig ntawm tus qauv.
3. Kev Txuas Ntxiv & Kev Tsim Cov Channel System: Kev tsim cov inlet channel, updraft channel, thiab cov cua channel.
4. Tshem Tawm Qauv: Thaum cov xuab zeb khov lawm, cov qauv raug tshem tawm, tawm hauv qhov khoob raws li cov khoom xav tau.
3. Kev Rho Hlau
Kauj ruam tom ntej yog kev yaj hlau. Cov hlau uas yuav raug pov yuav raug yaj ua kua siv ntau txoj kev, nyob ntawm hom hlau.
Rauv Melting
Muaj ntau hom cub tawg uas feem ntau siv rau hauv kev smelting hlau, suav nrog hluav taws xob arc cub tawg, induction cub tawg, thiab crucible cub tawg.
4. Ncuav Cov Hlau Uas Yaj Lawm
Thaum cov hlau yaj thiab kub txog ib qho kub, cov hlau uas yaj lawm yuav raug nchuav rau hauv pwm xuab zeb. Kev nchuav yuav tsum ua tib zoo kom tsis txhob muaj qhov tsis zoo ntawm kev casting xws li porosity lossis inclusions.
Txheej Txheem Nchuav
1. Kev Npaj Casting: Xyuas kom tseeb tias cov pwm xuab zeb npaj txhij thiab lub kaw lus channel tau teeb tsa kom raug.
2. Kev nchuav: Cov hlau uas yaj lawm raug nchuav los ntawm qhov nkag thiab puv qhov pwm kom txog thaum puv.
3. Txias: Tom qab nchuav tag, cia cov hlau uas yaj kom txias thiab tawv.
5. Kev Tshem Tawm Pwm
Thaum cov hlau tau tawv lawm, cov pwm xuab zeb yuav raug rhuav thiab cov khoom hlau yuav raug tshem tawm. Cov txheej txheem no hu ua kev tshem tawm pwm lossis kev co tawm.
6. Kev Ntxuav thiab Txiav
Cov khoom hlau uas nyuam qhuav raug tshem tawm ntawm cov pwm xuab zeb feem ntau tseem muaj cov xuab zeb seem thiab cov kab ke txuas nrog. Yog li ntawd, kev ntxuav thiab kev txiav yog qhov tsim nyog.
Kev ntxuav
Kev ntxuav yog ua kom tshem tawm cov xuab zeb uas tseem tshuav ntawm cov hlau. Cov txheej txheem no tuaj yeem ua tau los ntawm tes lossis siv tshuab.
Kev txiav ntoo
Kev txiav yog cov txheej txheem ntawm kev tshem tawm cov khoom tsis tsim nyog, xws li cov qhov nkag thiab cov qhov nce. Qhov no tuaj yeem ua tiav los ntawm kev siv lub tshuab txiav, riam, lossis lub tshuab txiav tshwj xeeb.
7. Kev Tshuaj Xyuas Zoo thiab Kev Ntsuas
Tom qab ntxuav thiab txiav cov khoom hlau lawm, kauj ruam tom ntej yog kev tshuaj xyuas zoo. Qhov no suav nrog kev tshuaj xyuas pom, kev sim tuab, kev sim lub zog, thiab lwm yam kev sim uas tsis ua rau puas tsuaj.
Kev Ntsuas Tsis Ua Rau Puas Tsuaj
– Kev Ntsuas Ultrasonic (UT): Siv cov nthwv dej ultrasonic los nrhiav cov qhov tsis zoo hauv cov hlau.
– Kev Kuaj Mob X-ray (RT): Siv cov duab X-rays lossis cov duab gamma los tshuaj xyuas cov qauv sab hauv ntawm cov hlau.
– Kev Ntsuas Cov Khoom Sib Nqus (MPT): Siv cov hmoov sib nqus los ntes cov kab nrib pleb hauv cov hlau.
Kev Ntsuas Kev puas tsuaj
Qhov kev sim no suav nrog kev txiav lossis rhuav tshem ib feem me me ntawm ib qho khoom kom sim nws lub zog lossis cov khoom siv sib xyaw.
8. Kev Ua Tiav
Theem kawg ntawm cov txheej txheem casting hlau yog kev ua kom tiav. Kev ua kom tiav suav nrog ntau yam txheej txheem los muab qhov chaw du thiab meej rau cov khoom hlau.
Cov Txheej Txheem Ua tiav
- Kev Sib Tsoo: Siv lub tshuab sib tsoo los ua kom cov hlau du.
- Machining: Cov txheej txheem ntawm kev machining kom ua tiav qhov ntev thiab kev kam rau siab.
- Kev Kho Mob Kub: Cov txheej txheem kho mob kub los txhim kho cov khoom siv kho tshuab ntawm cov hlau xws li qhov nyuaj thiab lub zog.
9. Txheej
Kev pleev xim yog txheej txheem ntawm kev ntxiv ib txheej tiv thaiv rau saum npoo ntawm cov hlau kom ua rau nws tiv taus xeb thiab hnav. Piv txwv ntawm kev pleev xim suav nrog galvanization, anodizing, thiab pleev xim.
10. Ntim thiab Xa Khoom
Thaum txhua theem ua tiav lawm, cov khoom siv hlau yuav npaj txhij rau kev ntim khoom thiab xa khoom. Kev ntim khoom yog ua los tiv thaiv cov khoom ntawm kev puas tsuaj thaum lub sijhawm thauj mus los. Kev xa khoom yog ua raws li cov neeg siv khoom xav tau.
Thoob plaws hauv cov txheej txheem casting hlau, ntau yam hloov pauv yuav tsum tau tswj hwm kom zoo kom ntseeg tau tias qhov zoo thiab kev ua raws li cov khoom tsim tawm. Nrog rau kev nce qib hauv thev naus laus zis, ntau yam txheej txheem niaj hnub thiab cov khoom siv tau tsim los txhim kho kev ua haujlwm zoo thiab qhov tseeb ntawm cov txheej txheem casting hlau.
Kev ua hlau yog ib txoj kev nyuaj uas xav tau kev nkag siab tob thiab kev txawj ntse tshwj xeeb. Txawm li cas los xij, qhov zoo uas nws muaj nyob rau hauv cov nqe lus ntawm lub peev xwm los tsim cov khoom ntawm cov duab sib txawv thiab ntau qhov ntau thiab tsawg ua rau nws yog ib qho ntawm cov txheej txheem muaj txiaj ntsig tshaj plaws hauv kev lag luam tsim khoom.
