Abstract:
A method for controlling the dimensions of an elongated material (10) rolled in a rolling mill comprising at least two mill stands (1, 2) arranged after each other, each of said stands comprising two spaced rolls (4, 5, 6, 7), said elongated material being fed between the rolls of each stand by rotating the rolls, wherein the material is subjected to stresses in the longitudinal direction thereof during the rolling operation, comprising:measuring in a first operation the width of a rear portion of a previously fed elongated material through said mill stands at a location downstream of a first stand while said rear portion is subjected to a first tension of a first magnitude; and subjecting a rear portion (14) of said material (10) to an additional tension with a second magnitude, based on said first tension of a first magnitude and said resulting measured width of said previously fed elongated material, substantially in the longitudinal direction of the material when a rear end (13) of the material is in the vicinity of said first stand (1) and has not passed said stand (1).
