Problems solved by technology

[0002] Due to its medium strength and excellent anodic oxidation performance, 6063 aluminum alloy has good application prospects in the field of smart phones. At present, the main manufacturing method of aluminum materials for smart phones is profile extrusion. The technical feature of extrusion is that the material grain is easy Control, but the extruded plate cannot be effectively thinned, the usual thickness is about 9mm, which leads to the extruded plate in the mobile phone parts processing plant, the aluminum blank needs CNC machining to cut off a large amount of metal, in order to obtain a finished mobile phone of about 0.8mm For the shell, aluminum metal is wasted seriously in this process, and the cost of CNC working hours is extremely expensive, which does not conform to the green and energy-saving industrial concept advocated by the state. For this reason, some aluminum factories try to use thin aluminum alloy rolled materials to save serious waste of metal and CNC. High man-hour cost, but due to its inherent limitations, the 6063 aluminum alloy rolled material makes it difficult to control material grain defects. Even with the new rolling process, there are still light material grain defects, which can only meet the general requirements of mid-range smart phones for appearance parts , and the material pattern defect is unstable, often exceeds the minimum acceptable standard of the mobile phone accessories factory, cannot be used, and the loss is relatively large

Embodiment 1

[0040] A method for processing 6063G aluminum alloys for smart phones is as follows: according to the alloy formula given in Example 1 in Table 1, aluminum water with corresponding alloy ratios is prepared and cast into ingots; the ingots are sent into a vertical pusher heating furnace for homogenization Annealing: heat up at a heating rate of 32°C / h. When the metal temperature rises to 540°C, keep it warm for 8 hours, then blow the fan to cool the ingot to 480°C, keep it warm for 2 hours, and then release the ingot from the furnace; roll it into coils; cool the coils After that, continue cold rolling to reduce to the intermediate solid solution thickness; then carry out intermediate solid solution on the continuous annealing line (reserve 32% cold working rate after intermediate solid solution), solution temperature: 520 ° C, holding time: 10s; off-line Afterwards, it is cold-rolled twice to the thickness of the finished product; returns to the continuous annealing line for fi...

Embodiment 2

[0043] A processing method of 6063G aluminum alloy for smart phones is as follows: according to the alloy formula given in Example 2 in Table 1, aluminum water with a corresponding alloy ratio is prepared and cast into an ingot; the ingot is sent into a vertical pusher heating furnace for homogenization Annealing: heat up at a heating rate of 40°C / h. When the metal temperature rises to 545°C, keep it warm for 9 hours, then blow the fan to cool the ingot to 490°C, keep it warm for 3 hours, and then the ingot is released from the furnace; hot rolled into coils; coils are cooled Finally, continue cold rolling to reduce to the intermediate solid solution thickness; then carry out intermediate solid solution on the continuous annealing line (reserve 40% cold working rate after intermediate solid solution), solution temperature: 530 ° C, holding time: 20s; off-line Afterwards, it is cold-rolled twice to the thickness of the finished product; it returns to the continuous annealing lin...

Embodiment 3

[0046] The steps of a processing method for a 6063G aluminum alloy for smart phones are as follows: According to the alloy formula given in Example 3 in Table 1, aluminum water with a corresponding alloy ratio is prepared and cast into an ingot; the ingot is sent into a vertical pusher heating furnace for homogenization Annealing: heat up at a heating rate of 45°C / h. When the metal temperature rises to 548°C, keep it warm for 9 hours, then blow the fan to cool the ingot to 490°C, keep it warm for 2.5 hours, and then the ingot is released from the furnace; hot rolled into coils; coils are cooled Finally, continue cold rolling to reduce to the intermediate solid solution thickness; then carry out intermediate solid solution on the continuous annealing line (reserve 45% cold working rate after intermediate solid solution), solution temperature: 540 ° C, holding time: 20s; off-line The last second cold rolling to the finished product thickness; return to the continuous annealing li...
