The difference between cold-rolled steel and hot-rolled steel is not in the smelting process, but in the rolling temperature, or the termination temperature of rolling. The finish rolling temperature lower than the recrystallization temperature of the steel becomes cold rolled steel. Hot-rolled steel is easy to roll and has high rolling efficiency, but the steel is oxidized under hot-rolled conditions, and the surface of the product is black and gray. Cold-rolled steel requires high mill power and low rolling efficiency, and intermediate annealing is required to eliminate work hardening during the rolling process, so the cost is also high, but cold-rolled steel has a bright surface and good quality, and can be directly used for processing Finished products, so cold-rolled steel sheets are widely used.
