Rolling mill stand with roll distance adjustment system

Abstract

A rolling mill stand (1) for rolling semi-finished iron-and-steel products, in particular for obtaining long products, comprising at least one pair of rolling rolls (2a 2b), each rolling roll (2a, 2b) being mounted on a respective shaft (3a, 3b); wherein each shaft (3a, 3b) is inserted in a respective eccentric bushing (4a, 4b), each adapted to rotate about a respective rotation axis (A, B), so that a rotation of the eccentric bushings (4a, 4b) allows an adjustment of the distance (G1, G2) between the rolling rolls (2a, 2b); characterized in that it comprises at least two distance sensors (51a, 52a, 51b, 52b) for each shaft (3a, 3b) adapted to detect the distance (c1, c2, c3, c4, d1, d2, d3, d4) between each sensor (51a, 52a, 51b, 52b) and the respective shaft (3a, 3b), or between each sensor (51a, 52a, 51b, 52b) and a body which supports the respective shaft (3a, 3b).
