Fig 4 Roll configurations in rolling mills. Twohigh mill roll configuration This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the work piece.

Rolling mills work by using multiple rollers to manipulate the physical properties of sheet metal. In steelmaking, they offer a uniform thickness and consistency for the steel sheet metal with which they are used. Rolling mills contain rollers that squeeze and compress sheet metal as it passes through them.
