What is Hot Rolling? - Definition from Corrosionpedia

Hot rolling breaks the grain structures and destroys the boundaries, giving rise to the formation of new structures with strong boundaries having uniform grain structures. Starting materials such as blooms or slabs at an elevated temperature flow from the continuous casting process directly into the rolling mills.

Cold Rolling – Process Overview - Matmatch

Cold rolling takes the hot rolled product and processes it further. After hot rolling, the steel is cooled to room temperature, then passed through cold rollers at a temperature lower than its recrystallisation temperature. This rolling process is called annealing and relieves stress and leads to a higher yield strength and greater hardness.
