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.

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.

There is evidence for rolling of lead and tin on simple 2high mills with castiron rolls at the beginning of the seventeenth century. At this point rolling mills did not process the high volumes of metal that we see today. In addition, the required quality of these early products was 'poor' if we measure it by today's exacting standards.

Abstract In flat steel rolling, roughing mills are used to roll slabs into thin plates within 5 to 7 consecutive reversing rolling passes with decreasing thickness. Some of these mills are equipped with edger rolls to control also the width of the plate. Edger rolls are usually mounted upstream of the roll gap.
