With just after cold rolling, the grain is flattened, elongated, lattice contorted distortion, grain breakage, the plasticity of metal is reduced, strength and hardness increase, this phenomenon is called processing hardening. The deformation resistance of steel is improved after the cold rolled strip is hardened, which brings difficulties to continuous cold rolling. In order to eliminate the hardening, most steel strips must be annealed in the process of recrystallization.
