In general, the following factors should be paid attention to in the production of aluminum profiles:
1, Be reasonable control of the extrusion temperature and speed when extrusing aluminum model. If the temperature is too low or too slow, can not play the role of solid solution strengthening.
2, should strengthen the air cooling conditions, the outlet of the profile fan less or not enough air, can not make the profile within the specified time to 200 degrees Celsius, the metal solution to reduce, directly affect the mechanical properties of aluminum.
3. If the ingots are not homogenized, Mg2Si precipitated from the ingots will not be able to be redissolved in a short time, thus affecting the product performance.
4. Reasonably determine the aging process, correctly install the thermocouple and reasonably arrange the profile to ensure the unobstructed circulation during heating.
