Understanding Rolling Process in Long Product Rolling …

Using the working diameter of the rolls, the roll rpm (revolutions per minute) is matched to the bar speed through the mill. As the rolls wear and the spread of the bar in the pass changes, the rpm of the stands need to be adjusted as the bar area changes. Most modern control systems modify the R-Factor as this occurs.
