Embodiment 17050
[0044] Example 1 Preparation of 7050 aluminum alloy ultra-wide plate
[0045] (1) The chemical composition of 7050 alloy is: Zn 6.2 wt%, Mg 2.2 wt%, Cu 2.3 wt%, Zr 0.1 wt%, Mn≤0.1 wt%, Ti≤0.06, Cr≤0.04 wt%, Fe≤0.15 wt% , Si≤0.12 wt%, the balance is Al and other unavoidable impurities.
[0046] (2) After batching, smelting, slag removal, degassing, and filtration according to the alloy composition, the alloy liquid is cast into an aluminum alloy square ingot by a low-speed semi-continuous casting process; the melting temperature is 720°C.
[0047] (3) The aluminum alloy ingot is placed in a heating furnace for homogenization treatment, and then the head and tail are cut off for surface milling. The homogenization treatment temperature is 450°C and the treatment time is 6.5h.
[0048] (4) The homogenized aluminum alloy ingot is subjected to 3 passes of hot rolling, and ultrasonic treatment is carried out at the same time to obtain a slab; the starting rolling temperature is 410...
