The method of controlling the hardness of aluminum alloy profiles

    1, temperature setting and control: usually, there is a certain error in the mild apparent temperature. When setting the temperature, it should be set according to the actual temperature of the furnace. Of course, we must pay close attention to the fluctuation of temperature.

    2, aluminum alloy profile aging and heat preservation: we must strictly follow the requirements of the process to make aging, keep warm time properly, prevent aging or overdue effect and make it hard enough.

    By 3, not too close to Aluminum Alloy extrusion, intervals between material and material, especially small material, windtight thick interval more bigger, when the tube material and small material, plate material with a box, put the tube material which is beneficial to the aging of circulating air.
