Embodiment 1
[0031] The invention provides an aluminum alloy used in high-throughput continuous casting and rolling with a narrow crystallization temperature range. The components and weight percentages of the components included in the aluminum alloy are as follows: Mg: 2.0%, Cr: 0.45%, Si: 0.15%, Cu: 0.02%, Mn: 0.06%, Ti: 0.016%, Fe: 0.14%, the balance is Al, and the product of this ratio is recorded as M1;
[0032] The preparation process of the aluminum alloy used in high-throughput continuous casting and rolling with a narrow crystallization temperature range mainly includes a smelting process, a casting process and a rolling process;
[0033] The first step melting process
[0034] After cleaning the furnace, add electrolytic aluminum solution;
[0035] When all the furnace materials are melted, the slag removal should be carried out in time within the temperature control range of the melt. Before the slag removal, the solvent must be evenly sprinkled into the furnace. The tempe...
