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 equipment, rolling is done in the ...Example for cold strip mill process.

- Hot Rolling is done in the 2-High Roll stands. Theory of Rolling Angle of Bite Top Roll Bottom Roll Input H0 Output H1 Theory of Rolling Angle of bite is 25-30 Degrees in case of Continuos Mills and a max of 20 Degrees in case of Cross-country Mills. The picture also indicates that the more the Roll Dia the more is the spread.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 work piece.

Definition of Rolling process: Rolling is defined as a process to form metals where the metal strip is pressed by two or multiple rollers, thus the uniform thickness is formed. To do this, the temperature is essential. There are two types of processes. One is Hot rolled and another is Cold Rolled.Stainless Steel Wire Rods Market Global Scenario, Market Size, Outlook, Trend and Forecast, 2016 – 2025 - Stainless steel wire rods are formed by hot rolling billets on continuous revolving mills. Stainless steel wire rods are on the demand of getting a extensive growth in the coming future.
