Description

Technical Field

[0001] This utility model relates to the field of annealing material rack technology, specifically an annealing material rack adapted to increase the furnace loading capacity of materials of different diameters. Background Technology

[0002] As is well known, aluminum alloy sheet, strip, and foil production requires annealing, which is generally divided into intermediate annealing and finished product annealing. During the rolling process of aluminum alloy, the grains slip and twist under the action of rolling force, and the lattice distortion intensifies, leading to an increase in the material's hardness and strength, and a decrease in plasticity and toughness (i.e., "work hardening"). If rolling continues, the material may crack due to brittleness. In this case, intermediate annealing is required. The coil is heated by furnace gas or held at a sufficient temperature (usually in the range of 150-400℃) for a period of time, allowing the atoms to obtain sufficient energy for diffusion, recrystallization of the grains, elimination of lattice distortion, restoration of the material's plasticity, and facilitating subsequent rolling. In addition, aluminum alloy sheets, strips and foils, after being rolled to the finished thickness whether or not they have undergone intermediate annealing, also face problems such as high strength, poor plasticity, oily surface, low conductivity, and poor corrosion resistance. To meet their usage needs, end customers will put forward specific technical requirements for the finished product. To meet these technical requirements, finished product annealing is necessary. This is mainly to ensure that the material properties ultimately meet the application requirements and optimize the performance. Finished product annealing is a key step in the transition of aluminum alloy sheets, strips and foils from the "processed state" to the "use state", and requires the use of an annealing rack.

[0003] An existing annealing material rack (CN202020049968.4) requires only three supports to support two aluminum coils, four supports to support three aluminum coils, and so on. The reduced number of supports reduces costs. However, it has shortcomings: the existing equipment cannot accommodate sleeves of different lengths, the flexible sleeve spacing is inconvenient to adjust, and it cannot be quickly extended and combined for adjustment, making it inconvenient to use. Therefore, an annealing material rack adapted to increase the furnace loading capacity of materials with varying coil diameters is needed to solve the above problems. Utility Model Content
