The production process of annealed coils includes stages such as heating, holding, and slow cooling of the cold rolled plate, covering energy consumption, material consumption, waste management, and environmental emissions required in the production process.

Carbon steel continuous annealed coil, typically refers to cold-rolled carbon steel coil that has been treated with continuous annealing process, is a material extremely common in industrial applications. Continuous annealed coil possesses good surface quality and uniform microstructure, ensuring its excellent mechanical properties and stable quality. Moreover, due to the annealing treatment, internal stresses of this type of steel have been relieved, reducing the risk of deformation and cracking during processing. Q235B carbon steel continuous annealed coil is a high-quality low-carbon steel material with good plasticity, toughness, and welding performance, and is widely used in automobiles, construction, machinery manufacturing, bridge structures, ships, and various industrial fields.
