Muaj ntau hom casting, uas feem ntau yog muab faib ua:
① Kev xuab zeb ib txwm muaj, suav nrog xuab zeb ntub, xuab zeb qhuav thiab xuab zeb uas tau kho los ntawm tshuaj lom neeg.
② Kev tsim tshwj xeeb, raws li cov khoom siv ua qauv, nws tuaj yeem muab faib ua kev tsim tshwj xeeb nrog cov xuab zeb ntuj tsim ua cov khoom siv ua qauv tseem ceeb (xws li kev nqis peev casting, av nkos casting, casting workshop plhaub casting, negative pressure casting, solid casting, ceramic casting thiab lwm yam) thiab kev tsim tshwj xeeb nrog hlau ua cov khoom siv casting tseem ceeb (xws li hlau pwm casting, pressure casting, tas mus li casting, low pressure casting, centrifugal casting, thiab lwm yam).
Cov txheej txheem casting feem ntau muaj xws li:
① Kev npaj cov pwm casting (cov thawv uas ua cov hlau ua kua rau hauv cov khoom castings). Raws li cov ntaub ntawv siv, cov pwm casting tuaj yeem muab faib ua cov pwm xuab zeb, cov pwm hlau, cov pwm ceramic, cov pwm av nplaum, cov pwm graphite, thiab lwm yam. Qhov zoo ntawm kev npaj pwm yog qhov tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov castings;
② Yaj thiab nchuav cov hlau cam khwb cia, cov hlau cam khwb cia (cam khwb alloys) feem ntau suav nrog hlau cam khwb cia, hlau cam khwb cia thiab cam khwb cia tsis yog ferrous alloys;
③ Kev kho thiab tshuaj xyuas casting, kev kho casting suav nrog kev tshem tawm cov khoom txawv teb chaws ntawm lub hauv paus thiab qhov chaw casting, tshem tawm cov pouring risers, kev sib tsoo ntawm burrs thiab seams thiab lwm yam protrusions, nrog rau kev kho cua sov, shaping, kev kho tiv thaiv xeb thiab kev ua haujlwm ntxhib.
Cov txiaj ntsig
(1) Muaj peev xwm pov ntau yam duab sib txawv ntawm cov castings, xws li lub thawv, thav duab, txaj, lub tog raj kheej thaiv, thiab lwm yam.
(2) Qhov loj thiab zoo ntawm cov castings yuav luag tsis muaj kev txwv, me li ob peb millimeters, ob peb grams, loj li kaum meters, ntau pua tons ntawm castings tuaj yeem raug pov.
(3) Muaj peev xwm pov cov hlau thiab cov hlau sib xyaw.
(4) Cov khoom siv casting yooj yim, kev nqis peev tsawg dua, casting nrog ntau yam khoom siv raw, yog li tus nqi ntawm casting qis.
(5) Cov duab thiab qhov loj ntawm qhov casting nyob ze rau qhov chaw, yog li ntawd, kev ua haujlwm ntawm kev txiav raug txo qis thiab ntau cov khoom siv hlau tuaj yeem txuag tau.
Vim tias casting muaj cov txiaj ntsig saum toj no, nws yog dav siv hauv kev tsim khoom ntawm cov khoom siv kho tshuab.
Cov txheej txheem casting muaj peb ntu tseem ceeb, uas yog kev npaj hlau casting, kev npaj pwm casting thiab kev ua casting. Hlau cam khwb cia yog cov khoom siv hlau siv rau kev casting castings hauv kev tsim khoom casting. Nws yog ib qho alloy uas muaj cov khoom hlau ua lub ntsiab lus tseem ceeb thiab ntxiv lwm cov hlau lossis cov khoom tsis yog hlau. Nws feem ntau hu ua casting alloy, feem ntau suav nrog hlau cam khwb cia, hlau cam khwb cia thiab cov hlau cam khwb cia uas tsis yog ferrous.
