A method of controlling a rolling mill comprising at least two mill stands (1,2) arranged after each other, wherein a first stand (1) is arranged upstream of a second stand (2). Each of said stands comprises two spaced rolls (3,4,5,6). An elongated material (8) is fed between the rolls of each stand by rotating the rolls. The width of the material (8) is measured at a location downstream of said second stand (2), and if the measured width is not within predefined first upper and lower limit values, an interstand tension between said first (1) and said second stand (2) 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 (8), to be within said first upper and lower limit values. |
