Roughing Mill - an overview | ScienceDirect Topics
The ever higher load capacities within the rolling process lead to increased stresses and vibrations of the main drives in hot rolling mills (Seelinger, et al., 2002). Further vibrations could also be excited through frequency converters or badly parameterised controllers. They are propagated via the motors to the drive chain.

Difference Between Hot and Cold Rolled Steel | Metal ...
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.

In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness, to make the thickness uniform, and/or to impart a desired mechanical property. The concept is similar to the rolling of dough.Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its ...
