Introduction to annealing of aluminum circle

1. Annealing of aluminum veneer
The annealing of aluminum veneer is divided into complete annealing and low temperature annealing. Its purpose is to control the final performance of aluminum veneer products and ensure that aluminum veneer products meet the requirements of technical standards. Complete annealing is used to produce soft products; low temperature annealing is to eliminate internal stress, stabilize material size, shape and properties, so as to obtain semi hard or hard products. The annealing process of finished product is more strict than that of intermediate annealing.
2. Complete annealing of aluminum sheet
The complete annealing temperature is 100 ~ 200 ° C higher than the recrystallization temperature
In order to prevent grain coarsening, or surface oxidation, gettering, and reduce recrystallization texture, the upper or lower annealing temperature should be reduced as much as possible. For the same aluminum sheet alloy, the appropriate annealing temperature should be determined according to different annealing equipment, product specifications, cold deformation, technical requirements and charging capacity. For the holding time, generally, the longer the holding time is, the more the charge, the thicker the product or the more uneven the temperature distribution. Heating speed in the premise of ensuring quality, it is best to use fast heating method. On the one hand, it can shorten heating time, save energy and improve productivity; on the other hand, it can refine grain and improve product quality. The cooling rate is the same as that of intermediate annealing.
