1. Thermal processing
Hot working refers to the plastic forming process completed by the aluminum feeding aluminum alloy ingot above the recrystallization temperature; during hot working, the ingot has higher plasticity and lower deformation resistance, and smaller capacity equipment can be used to produce larger deformation product.
2. Cold processing
Cold working refers to the plastic forming process completed below the temperature that does not produce recovery and recrystallization. The essence of cold working is the combination of cold working and intermediate annealing; cold working can achieve smooth surface, accurate size, good structure and performance, and meet different performance requirements The final product.
3. Warm processing
Warm working is a plastic forming process between cold and hot working; the main purpose of warm working is to reduce the deformation resistance of metals and improve the plastic properties of metals.




Precautions

1. Aluminum profile temperature setting and winter solstice: Generally, there is a certain error between the temperature and the apparent temperature. When setting the surface temperature, it should be set according to the actual temperature of the furnace, and pay close attention to temperature fluctuations;
2. Aging and heat preservation of aluminum profiles: the aging should be carried out in strict accordance with the process requirements, and the heat preservation time should be appropriate to prevent underaging or overaging from causing insufficient hardness;
3. Aluminum profile extrusion frame should not be too dense, and there must be a gap between the material and the material. The aluminum profile, especially the small and thick materials that are not ventilated, should be larger. The tube material, the small material, and the plate should be combined When framing, the pipe material is placed below, which is conducive to the aging cycle air supply.
