We all know that 5052 aluminum plate is obtained through cold treatment. There is an annealing process in the cold treatment process. Next, 5052 aluminum plate manufacturers will introduce the annealing process of 5052 aluminum plate to you.

1, 5052 aluminum plate annealing process is first set to 180° C furnace gas, heating rate is set to 35° C /h.

2. When the gas inside the furnace can reach 1800℃, carry out an aeration, and the oxygen content of the furnace is generally controlled below 0.1%.They then hold the heat for six hours so that the oil does not oxidize and become oily in an anaerobic environment.

3. The heating speed is set at 30℃/h, and the furnace gas is set at 235℃.When the coil temperature reaches 230 ° C, the insulation time is 3 hours and the desired mechanical properties are achieved.At this time, the residual oil is volatilized in the process, and the variation range of ambient temperature is controlled within (2450C-4000C);

4. Adjust the furnace gas to 0 ℃, and start the side cooler for rapid cooling.

The above is the introduction of the annealing process of 5052 aluminum plate. If you need to consult the price of 5052 aluminum plate, you can contact us.
