During material, temperature is 490-520 DEG C, and during discharging, temperature is 530-540 DEG C；
5) press quenching: the spray pattern that the aluminium section bar obtained uses water smoke is carried out cooling process, and at 2-3min
Inside cool the temperature to less than 200 DEG C；
6) cut off: the aluminium section bar after quenching is carried out cut-out process, is subsequently placed on cooling bed；
7) aligning: the aluminium section bar after cutting off is placed on cooling bed and is cooled to 50 DEG C, then carries out stretching process, the amount of stretching
Control the 1-2% at total length；
8) sawing: according to specification, the aluminium section bar after aligning is carried out sawing process, and then collection frames up and obtains finished product.
Further, described step 4) before extruding starts, first ingot-containing tube is carried out heat treated, be heated to 400-440
DEG C, then in extrusion process, prop up ingot every 20-50 and should carry out a cleaning treatment.
Further, described step 4) in pressure when playing pressure in extrusion process be 200-210kg/cm2。
Beneficial effect: the Production technology of aluminum alloy sectional bar of the present invention, eliminates the multiple heating in traditional handicraft and cooling
Operation, simplifies aluminium alloy extrusions extrusion process, reduces the energy loss of whole extrusion process, greatly improves production effect
Rate, reduces the production cost of aluminium alloy extrusions, the most also greatly reduces energy consumption and resource loss, decrease nature
The pollution of environment.
