What is Hot Rolling? - Definition from Corrosionpedia
Starting materials such as blooms or slabs at an elevated temperature flow from the continuous casting process directly into the rolling mills. In smaller operations the materials start at room temperature and must be heated either in a soaking pit, or by induction heating before being fed into the mill.

Difference Between Hot Rolled Steel and Cold Rolled Steel
Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), which is above the steel's recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.
