The special process of industrial aluminum profiles
is needed by industrial users, and the hardness of industrial aluminum profiles is strictly required, requiring high hardness. But not all the industrial aluminum profiles produced hardness can answer to the requirements, then in the end how to ensure the hardness of industrial aluminum profiles?
1. Industrial aluminum profiles temperature setting and control: usually, there is a certain error between temperature and surface visibility, set the table temperature need to be set according to the actual temperature of the furnace, and pay close attention to the fluctuation of temperature.
2. Industrial aluminum profiles aging insulation: In strict accordance with the process requirements for aging, insulation time to be appropriate, to prevent underaging or excessive aging and hardness is not enough. Billet framing and furnace loading.
3. Industrial aluminum profiles extrusion framing can not be too dense, there should be an interval between material and material, especially unventilated small material, thick material interval is more larger, tube material and small material, plate material in a box, pipe material put below this is conducive to aging circulation air supply.
4. Before loading, other special alloy and ordinary 6063 alloy should be separately loaded for aging. Because of production reasons, special alloy process should be used for aging in the same furnace. Aluminum extrusion produced by aluminum profile, without aging before the hardness is low, can not be used as a finished product, so generally must go through aging to improve the strength.
