Abstract

The invention discloses a steel strip annealing system which comprises a preheating device, a heating device and a cooling device which are sequentially arranged, the preheating device is used for preheating a steel strip and is of a double-layer structure, the steel strip is introduced into the first layer of the preheating device, and waste gas generated after combustion is introduced into the second layer of the preheating device; the heating device is used for annealing a steel strip and comprises two heating furnaces, the two heating furnaces are connected through a heat preservation connector, and each heating furnace is provided with four temperature control areas. The cooling device is used for cooling a steel belt and comprises a slow cooling section and a rapid cooling section, the slow cooling section is cooled through a cooling water jacket, and the rapid cooling section is cooled through cooling gas. According to the steel belt annealing system, accuracy and stability in the steel belt annealing process can be guaranteed, meanwhile, energy consumption is reduced, and the production quality of the steel belt is improved.

Description

technical field [0001] The invention relates to the field of heat treatment, in particular to a steel strip annealing system. Background technique [0002] Stainless steel strips need to be annealed during the production process. In production applications, continuous annealing can transform the deformed grains into uniform equiaxed grains, eliminate work hardening and residual internal stress at the same time, and restore the structure and properties of the steel to cold deformation. The heat treatment process of the previous state. However, the existing steel strip annealing system has disadvantages such as temperature instability, inaccuracy, and high energy consumption, which affect the production quality of the steel strip. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a steel strip annealing system, which can ensure the accuracy and s...
