Cov txheej txheem ntawm aluminium alloy tuag casting muaj xws li melting, refining, pwm ua, thiab pouring. Melting yog ib kauj ruam tseem ceeb hauv cov txheej txheem tuag casting; Kev tswj tsis txaus ntawm cov txheej txheem melting tuaj yeem cuam tshuam qhov zoo ntawm cov castings. Txhawm rau kom ntseeg tau tias qhov zoo ntawm cov molten aluminium, qhov kub ntawm lub melting yuav tsum tau khaws cia ntawm 720 thiab 750℃kom txo tau cov pa nqus. Cov khoom siv rov ua dua tshiab yuav tsum tau siv rau hauv pawg. Rau cov castings uas yuav tsum tau muaj ib tug ntom nrog cov qauv thiab airtightness, qhov kev faib ua feem ntawm recycled cov ntaub ntawv yuav tsum tau tswj hauv qab no 30%; rau cov castings zoo tib yam, qhov kev faib ua feem ntawm cov khoom siv rov ua dua tuaj yeem so mus rau 40%.
Refining yog cov kauj ruam tseem ceeb hauv kev tshem cov pa roj thiab cov khoom siv los ntawm cov molten aluminium. Txhawm rau kom muaj txiaj ntsig zoo thaum lub sijhawm ua kom zoo, lub sijhawm degassing rau aluminium alloy refining yuav tsum tsis pub tsawg dua 8 feeb. Tuag casting feem ntau yog ua haujlwm siab - siab lossis tshuab nqus tsev tuag casting tshuab, nrog pwm kub tswj ntawm 200-280℃thiab qhov kub ntawm qhov kub ntawm 650-720℃. Noj cov feem ntau siv tuag-cam khwb cia txhuas alloy ADC12 ua piv txwv, nws cov ntsiab lus hlau (Fe) tau pom zoo kom tswj tau ntawm 0.70% thiab 0.85%.
