>Rolling Process for Steel – IspatGuru
Rolling is the process of plastically deforming steel by passing it between rolls. Rolling is defined as the reduction of the cross sectional area of the steel piece being rolled, or the general shaping of the steel products, through the use of the rotating rolls. Rolling of steel is one of the most important manufacturing processes for steel.
