Description

Technical Field

[0001] The utility model relates to the field of aluminum profile production, and in particular to a waste heat utilization device for an aluminum profile production line. Background Art

[0002] The production equipment on the existing aluminum profile production line, such as melting furnace, homogenizing furnace, aging furnace, etc., produces high-temperature flue gas during the production process, which is discharged directly or after being treated by the dust removal system. The temperature of the high-temperature flue gas produced by the melting furnace reaches 800-1000℃, the temperature of the high-temperature flue gas discharged by the homogenizing furnace reaches about 600℃, and the temperature of the high-temperature flue gas discharged by the aging furnace can also reach 200℃.

[0003] Aging treatment in aging furnace: refers to the heat treatment process in which the alloy workpiece is placed at a higher temperature or at room temperature to maintain its performance, shape, and size over time after solution treatment, cold plastic deformation or casting, forging. If the aging treatment process is adopted in which the workpiece is heated to a higher temperature and aged for a shorter time, it is called artificial aging treatment. If the workpiece is placed at room temperature or natural conditions for a long time, the aging phenomenon is called natural aging treatment. The purpose of aging treatment is to eliminate the internal stress of the workpiece, stabilize the organization and size, and improve the mechanical properties. Aluminum profiles generally need to go through this process after finalization, and the aging furnace needs to work continuously for a long time after starting up, so the temperature during the period is kept at a higher temperature for a long time. Before entering the aging furnace, the aluminum profile needs to be preheated. At the same time, the temperature of the aluminum profile is usually as high as several hundred degrees after heat treatment, so it needs to be quickly dissipated. The heat dissipated is a kind of energy loss.
