Thick aluminum alloy plate annealing

When annealing thick aluminum alloy plates, the alloy, specification, batch number and quantity of the annealed aluminum plates must be checked against the production cards to prevent errors.

For different aluminum alloy aluminum plates, annealing should be carried out according to the corresponding annealing system.

The cold furnace should be preheated, and the preheating temperature should be the same as the first temperature of the aluminum plate annealing. After reaching the fixed temperature, keep it for 30 minutes before loading the furnace.

The loading of furnaces should be organized in batches, and the loading quantity and loading method should comply with the requirements of the corresponding process regulations of different annealing furnaces.

During the annealing process, the furnace temperature, temperature setting and heating time should be inspected on time, and any abnormalities should be dealt with in a timely manner.

During annealing, the height difference of the material pile in the furnace shall not exceed 200 mm, and the maximum height of the material pile shall not exceed 700 mm. Aluminum plates with different heat treatment systems cannot be annealed in the same furnace, and plates in the same pile with inconsistent lengths and widths cannot be annealed in the same furnace.
