Copper continuous annealing furnace is a common heat treatment equipment used for continuous annealing of copper materials. The working principle of copper continuous annealing furnace is relatively simple. Copper strip or copper material enters the heating chamber through a conveyor belt, and after being heated by a heater in the heating chamber, it reaches the required annealing temperature. Next, the copper material is kept in the heating chamber for a certain period of time to ensure complete annealing. Finally, the copper material is cooled by a cooler at the outlet to reduce its temperature to room temperature, thus completing the annealing process. The equipment has stable production quality, safe and convenient use, and does not produce industrial pollution.
