Kev tsim cov thawj aluminium tshwm sim ntawm cov kab ntau lawm. Thaum lub sij hawm smelting txheej txheem, alumina yog refined rau hauv txhuas. Aluminium atoms yooj yim ua ke nrog oxygen.
Txhawm rau tsim cov hlau txhuas, electrolysis yog tsim nyog. Alumina yog oxidized thiab yaj nyob rau hauv lub da dej electrolytic. Cov kua txhuas yog muab rho tawm los ntawm cov hlwb electrolytic siv cov cuab yeej tshwj xeeb thiab tom qab ntawd muab pov rau hauv cov ingots thiab billets rau kev ua haujlwm ntxiv.
Aluminium castings: Raw aluminium yog alloyed nrog lwm yam xws li tooj liab, manganese thiab silicon kom muaj zog, corrosion kuj thiab lwm yam khoom. Tom qab ntawd nws yog cam khwb cia rau hauv billets, remelted ingots, slabs, tuav thiab lwm yam castings rau ntxiv ua.
