Description

Technical Field

[0001] The utility model relates to the technical field of annealing racks, and particularly relates to an annealing rack for improving the loading capacity of double-zero foils into the furnace. Background Technique

[0002] In the production and processing field of aluminum products, in order to make the products meet the mechanical property requirements range required by customers, annealing is usually adopted. Especially for double-zero foil products, the conventional thickness range is 0.0055 - 0.007 mm. Annealing of the coil finished products is an essential process. After being slit, the double-zero foil finished products reach the coil weight and coil width required by downstream customers. The slit coil width and coil diameter are usually small. The conventional coil width range is 800 - 1200 mm, the length of a single coil is mostly 12000 - 12500 m, and the single-coil diameter range is 350 - 390 mm. In order to anneal the double-zero foil product finished products, currently in the industry, steel frameworks are generally selected for annealing in the annealing furnace. The existing steel frameworks adopt a structure with a relatively high height and a relatively small width. In order to ensure stability, there is also a certain distance between the height of the steel framework and the furnace top. The overall length, width, and height dimension ratio is unreasonable. During use, there are problems such as wasting the internal space of the annealing furnace, single structure, easy interference between the upper and lower layer coils, resulting in a small loading capacity, high energy consumption per ton of annealing, some extra-wide coils are not suitable for placement, inconvenient loading of the rack into the furnace, inconvenient loading and unloading of the coils, and potential safety hazards during the lifting process.
