Lub ntiajteb txawj nqus casting, tseem hu ua molding mus tas li, yog ib qho txheej txheem hlau casting uas siv cov pwm tuaj yeem siv tau. Nws muaj cov txiaj ntsig zoo li qhov tseeb qhov tseeb, zoo heev nto tiav, thiab cov khoom zoo ib yam rau cov khoom nruab nrab mus rau siab ntau lawm. nws thiab forging yog ob txoj kev tsim khoom sib txawv heev rau cov khoom siv hlau.
Ntawm no peb tshuaj xyuas txoj kev sib nqus, nws qhov zoo, thiab nws piv rau cov txheej txheem forging li cas.
Dab tsi yog Gravity Casting?
Hauvgravity casting, molten hlau yog poured rau hauv ib qho qhib-saum pwm mus tas li feem ntau ua los ntawm cam khwb cia hlau los yog hlau. Lub pwm kab noj hniav muaj cov duab ntawm qhov xav tau tiav. Lub ntiajteb txawj nqus ib leeg puv lub pwm, tsis muaj kev siv siab. Raws li cov hlau solidifies nyob rau hauv kev sib cuag nrog cov hlau pwm phab ntsa, tshav kub hloov heev tusyees kom tau zoo-grained castings.
Thaum lub casting muaj tag nrho solidified, lub puab halves yog qhib thiab ib feem raug tshem tawm. Cov pwm yog rov siv dua nyob rau hauv cov txheej txheem no, tso cai rau ntau lawm ntim. nws ua tau zoo ntawm cov geometry nyuaj thiab tuaj yeem muab qhov tseeb qhov tseeb thiab qhov zoo.
Nws yog haum rau cov hlau nrog zoo fluidity xws li txhuas, tooj liab, magnesium, thiab zinc alloys. Ferrous alloys kuj tuaj yeem yog lub ntiajteb txawj nqus cam tab sis yuav tsum tau txheej pwm los tiv thaiv kev yaig. Ntawm Tuam Tshoj Welong Foundry, peb leverage precision kev pab cuam los tsim cov khoom hlau zoo thoob plaws ntau yam kev lag luam.
Cov txiaj ntsig
Muaj ntau yam zoo uas ua rau nws yog ib txoj kev tsim khoom nrov:
- Reusable hlau pwm tso cai rau ntim siab ntawm tus nqi qis
- Kev hloov pauv sai sai ntawm cov pwm tsim cov qauv zoo
- Cov khoom sib xws thiab microstructure siv cov pwm ruaj khov
- Nyob ze cov duab castings txo machining
- Zoo heev nto tiav mus rau RMS 63 microns
- Zoo qhov tseeb qhov tseeb nyob ib puag ncig ±0.5% ntawm qhov kam rau ua
- Kov qhov nyuaj geometry nrog cov phab ntsa nyias thiab cov ntsiab lus
- Ntau yam ntawm cov hlau tuaj yeem raug nrum kom nruj
- Tsawg roj porosity tsis xws luag vim qhib pwm
Rau nruab nrab mus rau siab ntau lawm khiav ntawm 500 units los yog ntau tshaj, nws muab ib qho kev pom zoo tshuav nyiaj li cas, zoo ib yam, thiab nqi-zoo. Tuam Tshoj Welong Foundry muaj kev txawj ntse siv nws los tsim cov khoom hlau zoo uas ua tau raws li koj cov lus qhia meej.
Yuav ua li cas lub ntiajteb txawj nqus Casting piv rau Forging
Cov txheej txheem yas deformation zoo li forging daim hlau los ntawm kev siv lub zog compressive hauv zos, tsis zoo li casting qhov txhaws ntawm pwm. Muaj qee qhov sib txawv tseem ceeb:
- Castings nchuav rau hauv cov duab, forgings deform rau hauv cov duab
- Castings tuaj yeem tsim cov contours nyuaj rau forge
- Forgings nthuav qhia cov khoom taw qhia los ntawm cov hlau ntws
- Castings muaj ntau yam zoo sib xws nyob rau hauv tag nrho cov lus qhia
- Forgings tsim tsis muaj porosity defects tsis zoo li castings
- Castings muab qhov ze dua qhov kam rau ua
- Castings muaj cov cuab yeej qis dua rau cov ntim qis dua
- Forgings muaj zog thiab ductility ntau dua li castings
- Forgings xav tau ntau dua machining dua li castings
Feem ntau, forging ua rau kev txiav txim siab rau kev xav tau lub zog ntau dua, thaum casting yog qhov zoo tagnrho rau cov txheej txheem, cov ncauj lus kom ntxaws. Ntawm Tuam Tshoj Welong Foundry, peb tuaj yeem xa cov txiaj ntsig ntawm precision gravity casting lossis zoo forged Cheebtsam raws li txhua tus neeg thov kev thov tshwj xeeb.
Tsis ntev los no ua ntej
Kev tshawb fawb tsis tu ncua muab kev nkag siab zoo rau kev txhim kho kom zoo thiab muaj peev xwm ntxiv:
