Continuous annealing line (CAL)
Steel strip annealing is to even out the chemical composition and structure of the steel, refine the grain, adjust the hardness, eliminate internal stress and work hardening, and improve the forming and processing performance of the steel.
Continuous annealing is the process of heating the strip steel to an appropriate temperature under a protective atmosphere and keeping it for a certain period of time, and then cooling and overaging treatment. In order to improve the surface quality of the strip, an online leveling machine is generally designed.
