Description

Technical Field

[0001] The utility model relates to the technical field of annealing, in particular to an annealing device for aluminum alloy strips. Background Art

[0002] Annealing is a metal heat treatment process, which means slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability; reduce residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust structure, and eliminate structural defects. During the production and processing of aluminum alloy strips, annealing furnaces are required to perform heat treatment on aluminum alloy strips.
