Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy processing, and more specifically, to a hot blowing device for aluminum alloy cold rolling. Background Art

[0002] During the cold rolling process, aluminum alloy passes through rolling machinery equipment, such as rollers, and undergoes cold coiling and cold processing to reduce the material thickness and improve the surface quality. During the cold rolling process of aluminum alloy, some impurities and coolant often adhere to the surface of the plate and strip. If not removed in time, it will affect the product quality and subsequent processing.

[0003] After searching, the Chinese patent with announcement number CN217202837U discloses a purging device for a cold rolling mill of aluminum alloy plates and strips. In view of the fact that such purging devices on the market today are not convenient for uniform annealing of the aluminum alloy plates and strips, which makes them prone to cracking and breaking, the cold rolling mill body releases gas of corresponding temperature to the inside of the grid ventilation frame as needed, and then blows it evenly to the outer surface of the aluminum alloy plates and strips through the uniformly distributed pipe mouths, so as to achieve the purpose of uniform annealing, thereby effectively reducing the brittleness of the aluminum alloy plates and strips, and improving the plasticity of the aluminum alloy plates and strips, and reducing the phenomenon of cracking and breaking of the aluminum alloy plates and strips during the production process, and also reducing the one-time process trimming.

[0004] During use, the purging device adopts normal temperature airflow for purging, which makes it difficult to effectively remove impurities and coolant attached to the surface of the aluminum alloy plate during the cold rolling process, resulting in poor cleaning effect. Only one side of the aluminum alloy plate can be purged. If the other side is to be cleaned, it needs to be turned over, which reduces the efficiency of purging and cleaning. Utility Model Content
