Ua ntej ntxiv cov khoom me me ntawm cov khoom siv rov ua dua tshiab, aluminium alloy ingots nrog cov ntsiab lus qis qis (xws li Al-Si alloy), thiab tom qab ntawd loj dua aluminium ingots nrog cov ntsiab lus melting ntau dua thiab cov tswv alloys (xws li Al-Mn). Mg thiab lwm yam khoom siv tau yooj yim hlawv. Cov ntsiab lus ntxiv kawg. Cov khoom me me ntawm cov khoom siv rov ua dua tshiab yog thawj zaug pov rau hauv qab ntawm lub cub tawg los tiv thaiv lub tshuab hluav taws xob lub cev thiab txo qhov cuam tshuam rau ntawm phab ntsa ntawm lub cub tawg thaum cov khoom loj ntawm cov khoom siv hluav taws xob tau muab pov rau hauv.
Txij li cov khoom siv rov ua dua tshiab muaj qhov qis dua melting point thiab yooj yim rau yaj, cov melting efficiency tuaj yeem txhim kho thaum tom qab melting ntawm raw cov ntaub ntawv nrog cov ntsiab lus melting ntau dua. Thaum kawg, txo qhov kub thiab ntxiv Mg kom txo tau qhov hlawv.
Qee lub tuam txhab txhawb nqa tsheb hauv tsev siv cov qauv no thaum smelting aluminium alloys: ua ntej preheat lub melting rauv, pib noj tom qab ncav cuag qhov ntsuas kub, ua ntej ntxiv me me ntawm cov khoom siv rov qab rau hauv qab, thiab tom qab ntawd ntxiv cov khoom siv txhuas loj. Rau kev yooj yim Tom qab cov ntsiab lus hlawv.
