Embodiment 1
[0025] a. The cast aluminum alloy is a six-series aluminum alloy round ingot. The mass percentage of elements in the aluminum alloy ingot used is 0.42% Si, 0.095% Fe, 0.092% Cu, 0.090% Mn, and 0.58% Mg , Zn is 0.04%, Ti is 0.03%, Cr is 0.09%, single impurity ≤ 0.05%, total impurity ≤ 0.15%, and the rest is Al; the specification is Φ520mm×4000mm, and the ingredients are calculated by The center line of step a is used as the basis to ensure that the composition of the ingot is controlled within the standard range; slag removal once after melting, once after refining in the smelting furnace, once after refining in the holding furnace; degassing and heat preservation once after refining in the melting furnace One degassing after furnace refining, and one degassing machine degassing after holding furnace refining.
[0026] b. Cut the six-series aluminum alloy round ingot wagon with a specification of Φ520mm×4000mm, cut the head, cut the tail, take the lower magnification, chemical ...
Embodiment 2
[0031] The difference between this embodiment and Example 1 is that the size of the six-series aluminum alloy round ingot is Φ600mm×4000mm, and the size of the wool material is: Φ582mm×1800mm, and the degree of deformation can be increased by using the Φ582mm ingot.
[0032]The No. 6 aluminum alloy round ingot used in step a has a refining degree that meets the requirements of the primary oxide film, no metal compound segregation, and the ratio of Mg:Si in the chemical composition does not follow the principle of 1.73:1, resulting in excess Si, Fe, Zn , The smaller the composition of the Ti alloy, the better. In order to improve the purity of the 6063 alloy and increase the electrical conductivity; add Cu element and control it at the upper line of the standard to significantly improve the mechanical properties, and Cu can neutralize the adverse effects of Ti on the electrical conductivity; The Mn element is controlled on the upper line, which can eliminate the adverse effects ...
Embodiment 3
[0034] The difference between this embodiment and Example 1 is that the wool is homogeneous, the heating temperature is 560°C, and the heat preservation is 9 hours. The cooling method is: air cooling to 200°C and then spraying water to cool to room temperature. Check the oxide film at low magnification and check the compound segregation. Satisfy the requirements of the primary oxide film, other steps and parameters are the same as in Example 1.
