The rolling process is a metalforming process, in which a stock of the material is passed between one or more pairs of rollers to reduce and maintain the uniform thickness. This process is mainly focused on the crosssection of the ingot or the metal which is forming. Using this process, we can reduce the thickness of the metal workpiece.

A reversing mill is a rolling mill in which the workpiece is passed forward and backward through a pair of rolls. The reversing mill is so named because the steel runs back and forth between the rollers, reducing the thickness incrementally with each pass. A reversing mill can be used to reduce material to gauge.
