About the industrial aluminum hard through low how to prevent?

Temperature setting and control: 1, aluminium alloy profile commonly, temperature and table show temperature there must be errors, setting temperature table have to be set according to the actual temperature of the furnace, and close attention temperature shake.

2, aluminum aging heat preservation: we will strictly in accordance with the technical requirements for aging, heat preservation time should be appropriate, prevent short ageing hardness due to age or not. Blank frame, furnace charging

3, aluminum alloy profile extrusion to frame cannot be too close, want to have distance between materials and materials, aluminum especially unventilated sauce, thick distance more bigger, pipe material and small materials, sheet and packed in a wooden box, like this is advantageous to the aging cycle air supply pipe material.
