Technical Field

[0001] The utility model relates to the technical field of annealing devices, in particular to an annealing device used for softening straight materials. Background Art

[0002] During the softening process of long straight steel, the softness of the steel increases, making it easy to bend and deform, thus facilitating various metal processing such as cutting, curling, bending, etc. Steel softening treatment plays a vital role in metal processing. Commonly used steel softening treatment methods include annealing, homogenization and cold working. Annealing is a metal heat treatment process that refers to slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed.
