Casting is the first process of aluminum production. The main process is:
(1) batching: according to the specific alloy grades produced according to the needs, the amount of all kinds of alloy components can be calculated and reasonably matched with all kinds of raw materials.
(2) smelting: melt the raw material into the melting furnace according to the technical requirements and remove the slag and gas in the melt effectively by degassing and slag refining.
(3) casting: the molten aluminum melted into a round casting rod of various specifications by deep casting system under certain casting conditions.
