Kab rov tav Vacuum Nruam Casting Tshuab(HVCCM) yog cov khoom siv precision siv hauv kev lag luam metallurgical los tsim cov khoom hlau zoo. Cov thev naus laus zis no tau hloov pauv txoj kev hlau cam khwb cia thiab muaj ntau yam zoo dua li cov txheej txheem casting. Hauv tsab xov xwm no, peb yuav tham txog cov txheej txheem txheej txheem, cov khoom siv thiab kev siv ntawm cov kab rov tav lub tshuab nqus tsev casters.
Kawm txog kab rov tav lub tshuab nqus tsev nruam casting
Ua ntej delving rau hauv cov hauv paus ntsiab lus ntawm cov txheej txheem, nws yog ib qho tsim nyog yuav tsum nkag siab tias kab rov tav nqus nruam casting txhais li cas. Txoj kev koom nrog kev nruam nruam molten hlau mus rau hauv ib daim ntawv ruaj khov thaum tuav lub tshuab nqus tsev. Lub hom phiaj tseem ceeb yog los tsim cov khoom siv hlau purity siab nrog qhov tsis xws luag, uas yog qhov tseem ceeb rau kev lag luam xws li aerospace, automotive thiab electronics.
Cov khoom tseem ceeb ntawm HVCCM
Rauv: Cov txheej txheem pib nrog lub cub tawg qhov twg cov khoom siv raw yog rhuab mus rau lawv qhov melting point. Lub cub tawg feem ntau yog nruab nrog induction cua sov los yog hluav taws xob arc tshuab los xyuas kom meej txawm tias cua sov.
Cua sov rauv: Tom qab melting, cov hlau molten raug xa mus rau lub qhov cub tuav. Lub cub tawg tswj qhov kub ntawm cov hlau molten thiab xyuas kom nws nyob twj ywm kua kom txog thaum nws npaj txhij los nrum.
Casting Pwm: Cov pwm casting yog ib qho tseem ceeb ntawm HVCCM. Nws yog tsim los muab cov duab rau molten hlau raws li nws solidifies. Pwm feem ntau yog tsim los ntawm cov ntaub ntawv zoo uas tuaj yeem tiv taus qhov kub thiab txias.
Nqus Chamber: Lub tshuab nqus tsev chamber yog qhov chaw casting tiag tiag. Los ntawm kev tsim lub tshuab nqus tsev ib puag ncig, lub tshuab minimizes lub xub ntiag ntawm gases thiab impurities uas tuaj yeem ua rau muaj qhov tsis xws luag hauv cov khoom kawg.
Txias System: Thaum cov hlau molten poured rau hauv pwm, nws pib txias thiab solidify. Lub tshuab cua txias ua kom cov hlau txias sib npaug, tiv thaiv deformation lossis tawg.
Cov cuab yeej txiav thiab ua tiav: Tom qab solidification, cov khoom nruam nruam raug txiav mus rau qhov ntev uas yuav tsum tau ua thiab raug rau cov txheej txheem tiav kom ua tiav qhov yuav tsum tau ua kom zoo.
HVCCM txheej txheem txheej txheem
Cov txheej txheem txheej txheem ntawm kab rov tav lub tshuab nqus tsev nruam casting tuaj yeem muab faib ua ob peb theem tseem ceeb:
1. Melting thiab rwb thaiv tsev
Cov txheej txheem pib nrog cov ntaub ntawv raw melting nyob rau hauv lub cub tawg. Lub cub tawg yog tsim kom ncav cuag qhov kub thiab txias sai thiab ua tau zoo. Thaum cov hlau yog melted, nws yog pauv mus rau ib tug tuav lub cub tawg qhov twg nws yog tswj ntawm qhov kub thiab txias. Cov theem no yog qhov tseem ceeb vim nws ua kom cov hlau molten zoo ib yam thiab tsis muaj impurities.
2. Lub tshuab nqus tsev tsim
Ua ntej txheej txheem casting pib, lub tshuab nqus tsev yog tsim nyob rau hauv lub casting chamber. Qhov no yog ua tiav los ntawm kev siv lub tshuab nqus tsev twj tso kua mis kom tshem tawm cov cua thiab lwm yam gases ntawm lub chamber. Lub tshuab nqus tsev ib puag ncig yog qhov tseem ceeb los tiv thaiv oxidation thiab paug ntawm cov hlau molten, uas tuaj yeem ua rau muaj qhov tsis xws luag hauv cov khoom kawg.
3. Pouring molten hlau
Thaum lub tshuab nqus tsev tsim, cov hlau molten yog nchuav rau hauv pwm. Kev tsim cov pwm tso cai rau qhov nruam ntws ntawm cov hlau uas yog lub cim ntawm HVCCM txheej txheem. Kev saib xyuas yog ua thaum lub sij hawm pouring txheej txheem kom ntseeg tau tias cov hlau nyob rau hauv pwm tusyees thiab tsis muaj turbulence uas yuav qhia tau pa npuas.
4. Solidification
Raws li cov hlau molten nyob rau hauv pwm, nws pib txias thiab solidify. Cov txheej txheem cua txias yog ua tib zoo tswj kom ntseeg tau tias txawm tias solidification. Lub tshuab nqus tsev ib puag ncig ua lub luag haujlwm tseem ceeb ntawm no vim nws pab tswj qhov kub thiab txias thiab tiv thaiv kev tsim ntawm npuas.
5. Kev rho tawm tsis tu ncua
Ib qho ntawm qhov txawv ntawm HVCCM yog qhov kev tshem tawm tas li ntawm cov hlau khov kho los ntawm pwm. Raws li cov hlau solidifies, nws yog maj mam rub los ntawm pwm ntawm tus nqi tswj. Cov txheej txheem txuas ntxiv no ua rau ntev ntev ntawm cov khoom hlau uas tuaj yeem txiav mus rau qhov loj me.
6. Txiav thiab ua tiav
Thaum qhov ntev ntawm cov hlau yuav tsum tau rub tawm, nws raug txiav siv cov cuab yeej tshwj xeeb txiav. Cov txheej txheem tiav yuav suav nrog kev kho saum npoo, machining lossis lwm txoj hauv kev kom ua tiav cov kev xav tau tshwj xeeb. Cov khoom kawg yog tom qab ntawd xyuas kom zoo thiab sib xws.
Qhov zoo ntawm kab rov tav nqus nruam casting
Kab rov tav lub tshuab nqus tsev nruam casting tshuab muaj qhov zoo hauv qab no piv nrog cov txheej txheem casting ib txwm:
Siab Purity: Lub tshuab nqus tsev ib puag ncig minimizes muaj gases thiab impurities, ua rau high-purity hlau cov khoom.
Txo qhov tsis xws luag: Cov txheej txheem tswj kev ua kom txias thiab khov kho txo qhov muaj peev xwm ntawm qhov tsis xws luag xws li qhov pores thiab suav nrog.
Kev Tsim Nyog: Covnruam castingtxheej txheem tuaj yeem tsim cov hlau ntev, txo cov khoom pov tseg thiab ua kom cov khoom tsim tau zoo.
VERSATILITY: HVCCM tuaj yeem siv rau ntau yam hlau, suav nrog txhuas, tooj liab thiab cov hlau tshwj xeeb, ua rau muaj ntau yam kev xaiv rau cov tuam txhab.
Tus nqi siv tau: Thaum qhov kev nqis peev thawj zaug hauv HVCCM thev naus laus zis tuaj yeem siab, kev txuag nyiaj mus sij hawm ntev hauv cov nqi khoom siv thiab kev txhim kho hauv kev tsim khoom ntau dua cov nqi no.
Kev siv HVCCM
Kab rov tavlub tshuab nqus tsev nruam casting tshuabyog dav siv nyob rau hauv ntau yam lag luam, xws li:
Aerospace: High-purity hlau yog qhov tseem ceeb rau cov khoom siv hauv aerospace qhov kev ua tau zoo thiab kev ntseeg siab yog qhov tseem ceeb.
Automotive: Kev lag luam tsheb yuav tsum muaj cov khoom siv hlau zoo los tsim cov khoom siv cav, cov khoom sib kis thiab cov khoom siv.
Electronics: Kev lag luam hluav taws xob tso siab rau cov hlau purity siab los ua cov khoom siv hluav taws xob, cov khoom sib txuas thiab lwm yam khoom siv.
Cov cuab yeej kho mob: Kev kho mob xav tau cov ntaub ntawv uas ua tau raws li cov qauv zoo, ua rau HVCCM zoo tagnrho rau kev tsim cov khoom siv kho mob.
nyob rau hauv xaus
