Abstract
A method of controlling a rolling mill comprising at least two mill stands ( ) arranged after each other, wherein a first stand ( ) is arranged upstream of a second stand ( ). Each of said stands comprises two spaced rolls ( ). An elongated material ( ) is fed between the rolls of each stand by rotating the rolls. The width of the material ( ) is measured at a location downstream of said second stand ( ), and if the measured width is not within predefined first upper and lower limit values, an interstand tension between said first ( ) and said second stand ( ) is adjusted to a value corresponding to the deviation of the measured width from said predefined limit values in order to control the width of said material ( ), to be within said first upper and lower limit values.
