Rolling is carryout on a rolling mill and can be performed in two ways; hot and cold process. The rolling mill consists of two more working rollers, supporting rollers, roll stands, a drive motor, a flywheel, a reducing gear, a coupling gear, etc. The rollers may be plain or grooved depending upon the shape of the product rolled.

Hot 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.
