[0002] A common equipment used in metal processing is a rolling mill. A rolling mill is a device used to change the shape and size of a metal billet by squeezing and deforming it. A rolling mill consists of one or more pairs of rollers, which are usually made of solid metal billets such as steel or iron. The metal billet is fed between the rollers of the rolling mill, and the squeezing and rolling action of the rollers gradually flattens, elongates, or changes the cross-sectional shape of the billet.
