In the rolling process, the job is drawn through a set of rolls due to interface friction, and the compressive forces reduce the thickness of the workpiece or change in its cross-sectional area.. The types of rolls used in rolling mills are depended upon the shape, size and the gap between the rolls and their contour. Because of workability and limitations in …

Fig 4 Roll configurations in rolling mills. Two-high 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 …

The primary finishing refinement for sheet steel is being further hot-rolled in the rolling mills. Rolling mills are just a series of rollers and hot-rolling just means that the steel is at a high temperature while it is being rolled. Before the slabs can be rolled, they need to be reheated to about 2400 degrees Fahrenheit and then need descaled.
