Problems solved by technology

However, the aluminum alloy radiator profiles for 4G base stations are large in size, complex in cross section, asymmetric in shape, thick at the bottom and thin in teeth, so the general on-line quenching process often leads to serious deformation of the tooth surfaces of the radiator profiles
Although there are also a small number of aluminum processing enterprises in my country that have extrusion equipment of more than 10,000 tons, these equipments have the production capacity of aluminum alloy radiator profiles for 4G base stations, but due to the lack of a suitable online quenching process, no enterprises are able to produce Produced aluminum alloy radiator profiles that meet the construction requirements of 4G base stations

Embodiment 1

[0042]The on-line quenching process for aluminum alloy radiator profiles provided in this example includes the following steps: Extruding a large-sized 6061 aluminum alloy round ingot under the conditions of a mold heating temperature of 480°C and an extrusion barrel temperature of 430°C, When extruding, the extrusion ratio is 9.0, and the extrusion speed is 1m / min. After extrusion, the blower is used to blow the bottom of the extruded aluminum alloy radiator profile to ensure that the wind speed at the bottom of the aluminum alloy radiator profile is 40m / s, the wind speed on the top and both sides of the aluminum alloy radiator profile is 0m / s.

[0043] The present invention also provides the aluminum alloy radiator profile produced by the above online quenching process.

Embodiment 2

[0045] The online quenching process of the aluminum alloy radiator profile provided in this embodiment includes the following steps:

[0046] The holding temperature of large-size aluminum alloy round ingots starts at 495°C, and gradually increases to 520°C from near the extrusion to far away from the extrusion;

[0047] Under the conditions of mold heating temperature of 520°C and extrusion cylinder temperature of 460°C, large-scale 6063 aluminum alloy round ingots were extruded with an extrusion ratio of 9.2 and an extrusion speed of 1.4m / min;

[0048] After extrusion, the bottom of the extruded aluminum alloy radiator profile is blown by a fan. The wind speed at the bottom of the aluminum alloy radiator profile is 50m / s, and the wind speed at the top and both sides of the aluminum alloy radiator profile is 0m / s.
