Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for aluminum alloy annealing processes, specifically to an intermediate annealing material rack that increases the furnace loading capacity. Background Technology

[0002] As is well known, aluminum alloy sheet, strip, and foil products require intermediate annealing during production according to process requirements. This is because work hardening occurs during processing, leading to increased material hardness and decreased toughness, making subsequent processing more difficult. Intermediate annealing allows metal atoms to gain sufficient energy, causing recrystallization, eliminating work hardening, restoring the material's plasticity and toughness, and facilitating further processing. Furthermore, the microstructure of aluminum becomes uneven during processing; intermediate annealing allows alloying elements to diffuse fully and distribute evenly, promotes grain growth, reduces grain boundary area, minimizes defects and stress concentration at grain boundaries, and improves the overall performance of the material. However, intermediate annealing of aluminum alloys typically consumes a significant amount of electricity because it requires heating the aluminum material to a certain temperature and holding it for a period of time. During this process, the heating equipment consumes a large amount of electrical energy to generate heat. To improve production efficiency and reduce energy consumption, companies consider furnace loading as an important performance indicator when performing intermediate annealing.

[0003] Currently, the internal dimensions of annealing furnaces are generally 12000mm*26000mm*26000mm (length*width*height), and the diameter of billet coils is generally between 2400-2500mm. Due to order variations, billet widths may differ, requiring different rolling mill specifications for production. Furthermore, the length of sleeves used by different rolling mills also varies. For example, 1300mm wide billets require a 1950mm rolling mill with a 1950mm sleeve, while 1200mm wide billets require an 1850mm rolling mill with a 1600mm sleeve. Consequently, the annealing charge is greatly affected by different billet widths and rolling mill production, resulting in significant variations. For instance, a single furnace charge for 1700mm wide billets is approximately 100 tons, while a single furnace charge for 1200mm wide billets is less than 71 tons. This leads to wasted annealing capacity and high energy consumption for narrow-width materials, necessitating an intermediate annealing rack with increased charge capacity to address these issues.
