Embodiment 1
[0030] refer to figure 1 as shown,
[0031] Follow the steps below to produce aluminum rods
[0032] Put 99.70% aluminum ingots into the melting furnace, transfer to the holding furnace, adjust the temperature to maintain 740 °C, add aluminum-boron alloy, aluminum rare earth alloy, aluminum-iron alloy; adjust the mass ratio of elements to iron 0.17%, silicon 0.035%, boron 0.03%, lanthanum 0.08%, manganese, titanium, chromium and vanadium are controlled below 0.01%, adding refining agent for refining; stirring for 30 minutes, keeping the temperature at 740°C for 30 minutes; 0.6kg / cm2, the temperature is 750°C; after purification, it is filtered through a 40-mesh ceramic filter plate, passed through a large upper and lower ladle, and enters the casting machine in a horizontal casting mode, passes through a continuous rolling mill, and is cooled by a climbing rod to form a circle and close the rod; the casting temperature is 690 °C, the rolling temperature is 460 °C, and the cl...
