What elements should be paid attention to in the extrusion process of industrial aluminum profiles

Factors to pay attention to in the extrusion process of industrial aluminum profiles:

①Temperature control: For extrusion production, extrusion temperature is the most basic and critical process factor. Extrusion temperature has a great impact on product quality, production efficiency, die life, energy consumption, etc.

②Extrusion speed: The extrusion speed must be carefully controlled during the extrusion process. The extrusion speed has an important influence on the thermal effect of deformation, the uniformity of deformation, the recrystallization and solid solution process, the mechanical properties of the product and the surface quality of the product.

③On-machine quenching: 6063-T5 quenching is to keep the Mg2Si solid dissolved in the base metal at high temperature out of the die hole and rapidly cooled to room temperature. The cooling rate is often proportional to the strengthening phase content. The minimum cooling rate that 6063 alloy can be strengthened is 38°C/min, so it is suitable for air-cooled quenching. Changing the fan and fan revolutions can change the cooling intensity, so that the temperature of the product before tension straightening drops below 60°C.
