Casting yog hais txog cov txheej txheem uas cov hlau yog rhuab kom txog thaum molten thiab ces poured rau hauv pwm; nws yog qhov zoo- haum rau kev tsim khoom nrog cov duab geometry nyuaj.
Classification ntawm Casting Methods:
Xuab zeb Casting: Tus yam ntxwv los ntawm tus nqi qis thiab tsim nyog rau me me - batch ntau lawm, txoj kev no tso cai rau kev tsim cov duab nyuaj, txawm hais tias nws yuav xav tau ntau qhov kev tshaj tawm - kev ua haujlwm.
Kev nqis peev Casting (Post-Wax Method): Cov txheej txheem tsim khoom no muaj qhov tshwj xeeb sib xws thiab qhov tseeb, thiab tseem muaj peev xwm tsim cov duab zoo nkauj. Nws muab cov khoom zoo tshaj plaws ntawm cov nqi ua haujlwm qis, ua rau nws zoo tagnrho rau kev tsim khoom loj.
Lub ntiajteb txawj nqus Casting: Siv rau kev tsim cov duab nyuaj uas qhov siab dua qhov siab siab tau txais. Vim yog qhov tshwm sim ntawm tus txheej txheem, cov khoom tiav feem ntau yuav tsum tsis muaj kev tshaj tawm - ua tiav; Txawm li cas los xij, nws tus nqi -kev ua tau zoo yog pom tau tsuas yog nyob rau hauv cov ntsiab lus ntawm kev tsim khoom loj. Tuag Casting: Koom nrog cov nqi pib ua haujlwm siab, ua rau nws siv tau nyiaj txiag tsuas yog hauv cov xwm txheej ntau lawm. Txawm li cas los xij, tus nqi ntawm cov khoom kawg tseem tseem qis, thiab qhov ntev ntawm qhov kam rau ua yog feem ntau siab dua. Nws yog tsim rau tsim cov khoom nrog nyias phab ntsa.
Centrifugal Casting: Ib txoj hauv kev zoo tshaj plaws rau kev tsim cov khoom me me, feem ntau ua haujlwm hauv cov hniav nyiaj hniav kub ua. Roj hmab pwm tuaj yeem siv los pab txo cov nqi ua haujlwm.
Directional Solidification: Pab kom tsim tau cov khoom muaj zog tshwj xeeb, super- tshav kub- resistant alloys nrog superior qaug zog. Cov hlau molten yog poured rau hauv pwm thiab raug nruj tswj xyuas cua sov thiab cua txias mus rau tshem tawm txawm lub feem ntau tsis xws luag. Plastic forming Section: Plastic forming: Hais txog cov txheej txheem ntawm cov cua sov hlau kom kub kub kom hloov nws; qhov no feem ntau yog kev ua haujlwm - cov txheej txheem tsim khoom hnyav.
