Description
Technical Field
[0001] The utility model relates to the technical field of annealing furnaces, and particularly relates to a louver swing air guiding type circulating air device. Background Technique
[0002] An annealing furnace is a special equipment used for performing annealing treatment in metal processing. Annealing is a heat treatment process aimed at changing the microstructure of metal materials, thereby improving their mechanical properties. For coil materials (such as aluminum coils), the main purpose of annealing is to soften the material, improve its plasticity, reduce internal stress, and improve the uniformity and mechanical properties of the material. This makes the aluminum coil easier for subsequent processing, such as stamping, bending, etc., and helps to extend the service life of the product.
[0003] The air circulation system design of traditional annealing furnaces is often relatively simple and lacks effective guiding and regulating mechanisms. This results in the formation of local eddies and dead zones when air flows in the furnace, making the temperature distribution in the furnace uneven. Therefore, there is an urgent need for a louver swing air guiding type circulating air device. Content of the Utility Model
