Embodiment 1
[0085] The alloy is pure aluminum / 7050, the ingot size: thickness 300mm×width 600mm×length 800mm, the thickness of the 7050 alloy layer is 245mm,
[0086] Casting temperature: 720°C,
[0087] Casting speed (casting box drop speed): 60mm / min (pure aluminum), 20mm / min (7050 alloy),
[0088] Flow control method: lift the guide rod, 20mm (pure aluminum), 10mm (7050 alloy),
[0089] The running speed of translational diverter mechanism: 100mm / min (pure aluminum), 60mm / min (7050 alloy).
[0090] The cast ingot has no cracks, no cold shut on the surface, can be sawed in the cast state, and the inclusions reach A grade after ultrasonic flaw detection. The internal structure of the ingot is uniform, and the average grain size is 260 μm (see Figure 18 ). Macro segregation rate of alloying elements [(maximum value of ingot alloy element content - minimum value) / average value]: Zn is 3.1%, Mg is 5.9%, Cu is 6%, and the macroscopic composition clouds of Zn, Mg, and Cu are respectively...
