Embodiment 1
[0025] An aluminum alloy heat treatment process, comprising the following steps:
[0026] (1) Quenching
[0027] After the aluminum alloy profile products are extruded out of the outlet, all the quenching fans are started immediately to forcibly cool them. The cooling speed is that the temperature of the profile when passing through the tail fan in the air-cooling area is less than or equal to 200°C (if equipped with a tractor, the tractor should be started in time), and the operation of the fan should be checked frequently, and the maintenance personnel should be notified immediately if any problem is found. Cold quenching effect, the profile outlet temperature is controlled at 520°C;
[0028] (2) Artificial aging
[0029] Heat the quenched aluminum alloy profile to 190°C in the aging furnace, and then keep it warm for 2 hours. During the process, record the temperature every 30 minutes and check whether the instrument is normal, so as to prevent the aging from running out ...
Embodiment 2
[0040] An aluminum alloy heat treatment process, comprising the following steps:
[0041] (1) Quenching
[0042] After the aluminum alloy profile products are extruded out of the outlet, all the quenching fans are started immediately to forcibly cool them. The cooling speed is that the temperature of the profile when passing through the tail fan in the air-cooling area is less than or equal to 200°C (if equipped with a tractor, the tractor should be started in time), and the operation of the fan should be checked frequently, and the maintenance personnel should be notified immediately if any problem is found. Cold quenching effect, the profile outlet temperature is controlled at 550°C;
[0043] (2) Artificial aging
[0044] Heat the quenched aluminum alloy profile to 200°C in the aging furnace, and then keep it warm for 2 hours. During this process, record the temperature every 30 minutes and check whether the instrument is normal, so as to prevent the aging from running out...

The cooling speed is that the temperature of the profile when passing through the tail fan in the air-cooling area is less than or equal to 200°C (if equipped with a tractor, the tractor should be started in time), and the operation of the fan should be checked frequently, and the maintenance personnel should be notified immediately if any problem is found. Cold quenching effect, the profile outlet temperature is controlled at 535°C;
[0058] (2) Artificial aging
[0059] Heat the quenched aluminum alloy profile to 195°C in the aging furnace, and then keep it warm for 2 hours. During this process, record the temperature every 30 minutes and check whether the instrument is normal, so as to prevent the aging from running out...
