In hot strip finish rolling, a commonly occurring problem is that the tail end of a strip steel sheet walks and that its edge touches the side guide on the entry side of the next rolling mill stand after it comes off a rolling mill stand and buckles the edge, which is then folded and rolled by the next rolling mill stand (Photo 1). When this

Rolling Process Definition. The rolling process is a metalworking operation in which metal strips pass through a set of rollers to reduce sheet thickness and achieve uniform thickness throughout the sheet. The sheet is deformed along the linear axis. Typically after the rolling, metal sheets go through annealing which is done under a closed environment of nitrogen.
