Example Embodiment
[0030] Embodiment 1: The casting and rolling method of an aluminum alloy plate of this example is used to produce 3004 aluminum alloy plate. The steps are:
[0031] a. Put the leftovers into the smelting furnace first, and then into the aluminum ingot. The ratio of the leftovers to the aluminum is: Si: 0.1%, Fe: 0.4%, Cu: 0.1%, Mn: 1.0%, the balance is Al, and the melting will be completed soon Add the alloying agent according to the composition ratio. The ratio of the alloying agent composition to the aluminum is: Si: 0.15%, Fe: 0.56%, Cu: 0.15%, Mn: 1.15%, Mg: 0.9%, and then stand for 30 minutes. Add 2.5kg of refining agent for refining, and adjust the pressure of liquid nitrogen at the same time to ensure that the height of the liquid nitrogen blowing up the aluminum liquid does not exceed 15cm. The refining time is controlled at 15 minutes. After the refining is completed and the slag is removed, the smelting is carried out. The smelting time is 4 hours. The temperature is 7...
Example Embodiment
[0034] Embodiment 2: The casting and rolling method of an aluminum alloy plate of this example is used to produce 3004 aluminum alloy plate, and the steps are:
[0035] a. Put the leftovers into the smelting furnace first, and then put into the aluminum ingot. The ratio of the leftovers to the aluminum is: Si: 0.12%, Fe: 0.45%, Cu: 0.12%, Mn: 1.05%, the balance is Al, and the melting is almost complete Add the alloying agent according to the composition ratio. The ratio of the alloying agent composition to the aluminum is: Si: 0.2%, Fe: 0.63%, Cu: 0.2%, Mn: 1.25%, Mg: 1.1%, and then stand for 30 minutes. Add 3.5kg of refining agent for refining, and adjust the pressure of liquid nitrogen at the same time to ensure that the height of the liquid nitrogen blowing up the molten aluminum does not exceed 15cm. The refining time is controlled at 18 minutes. After the refining is completed and the slag is removed, the smelting is performed. The smelting time is 4.5 hours. The temperatur...
Example Embodiment
[0038] Embodiment 3: The casting and rolling method of an aluminum alloy plate of this example is used to produce 3004 aluminum alloy plate, and the steps are:
[0039] a. Put the scraps into the smelting furnace first, and then into the aluminum ingot. The ratio of the scraps to the aluminum is: Si: 0.15%, Fe: 0.5%, Cu: 0.15%, Mn: 1.1%, the balance is Al, and the melting is almost complete Add the alloying agent according to the composition ratio. The ratio of the alloying agent composition and aluminum is: Si: 0.25%, Fe: 0.68%, Cu: 0.23%, Mn: 1.3%, Mg: 1.2%, and then let it stand for 30 minutes. Add 4kg of refining agent for refining, while adjusting the liquid nitrogen pressure to ensure that the height of the liquid nitrogen blowing up the aluminum liquid does not exceed 15cm. The refining time is controlled at 20 minutes. After the refining is completed and the slag is removed, the smelting time is 5 hours. The melting temperature The temperature is 765°C, and then go to th...
