Muaj ntau hom kev ua pov thawj, uas yog muab faib ua:
Sandal dog dig xuab zeb casting, suav nrog ntub xuab zeb, qhuav xuab zeb thiab xaim qhuav xuab zeb.
Pasting tshwj xeeb, raws li cov qauv ua qauv, av casting, tsis zoo Casting, Khoom Casting, Ceramic casting thiab lwm yam Cov.) thiab tshwj xeeb castings nrog hlau raws li cov khoom tseem ceeb casting (xws li hlau pwm Casting, Siab Casting, Tsis Muaj Casting, Centrifugal Casting, thiab lwm yam).
Txheej txheem casting feem ntau suav nrog:
‡ Kev npaj pwm (cov thawv ntim khoom uas ua rau cov hlau ua kua rau hauv cov khoom siv startings). Raws li cov ntaub ntawv siv, casting pwm tuaj yeem muab faib ua cov xuab zeb, cov pwm, cov pwm ua pwm, cov khoom siv cov ntoo ua ke cuam tshuam rau qhov zoo ntawm cov cuab yeej;
② Melting thiab nchuav cov hlau nrum, nrum hlau (cam khwb cia hlau (cam khwb cia
③ Casting kho thiab tshuaj xyuas, ua rau kev kho mob los ntawm kev sib tsoo txawv teb chaws thiab sib tsoo, kev kho cua sov, tshuaj tiv thaiv xeb thiab ntxhib machining Cov.
Qhov Zoo
(1) tuaj yeem pov ntau hom ntawm cov duab ua plaub ntawm cov nrib, xws li lub thawv, thav duab, lub tog raj kheej thaiv, thiab lwm yam.
(2) Qhov loj me thiab qhov zoo ntawm cov camettings yog yuav luag tsis muaj kev cuam tshuam, ib ob peb gram, ntau dua, ntau pua ntawm tons ntawm cov nrib pleb tuaj yeem raug pov.
(3) tuaj yeem nrum cov hlau thiab alloy castings.
(4) Casting cov khoom siv khoom tsim khoom yog yooj yim, kev nqis peev dua, ua rau muaj cov khoom siv raw, yog li tus nqi ntawm cov khoom siv cov khoom siv tsawg.
(5) Tus qauv thiab qhov loj me ntawm cov cam khwb cia yog ze rau cov ntu, yog li cov haujlwm ua haujlwm ntawm kev txiav tawm thiab ntau cov ntaub ntawv hlau tuaj yeem txuag tau.
Vim tias casting muaj cov txiaj ntsig saum toj no, nws yog dav siv nyob rau hauv cov chaw tsim khoom ntawm cov tshuab.
Txheej txheem casting tuaj yeem faib ua peb ntu yooj yim, uas yog cas tsuas yog ua khoom siv hlau, casting pwm. Cov khoom siv nrum txuas rau cov khoom siv hlau siv rau casting casting castings hauv kev tsim khoom. Nws yog ib qho alloy muaj li ntawm cov hlau ntoo raws li lub ntsiab tivthaiv thiab lwm yam hlau lossis cov hlau tsis yog ntxiv. Nws yog kev cai hu ua casting alloy, feem ntau yog suav nrog cam khwb cia hlau, cam khwb cia hlau thiab nrum tsis-ferrous alloys.
