Continuously annealed coils, typically referring to cold-rolled carbon steel coils treated by continuous annealing processes, are highly common materials in industrial applications. These coils exhibit excellent surface quality and uniform microstructure, ensuring superior mechanical properties and consistent quality. Additionally, due to the annealing treatment, internal stresses in the steel are relieved, reducing the risk of deformation and cracking during processing. Key characteristics of silicon steel continuously annealed coils include low iron loss, high permeability, and good stability. It is commonly used to manufacture transformer cores, as well as stators and rotors of electric motors and generators. It can also be applied in other areas requiring precise control of electromagnetic properties, such as power transmission and electronic devices.
