Rolling stand for rolling mills in general, with three or more controlled and adjustable rollers

摘要

A rolling stand 5 in general is described, comprising at least three controlled rollers 27, 28, 29, having their respective axes of rotation A1, A2, A3 arranged at an adjustable distance from a rolling axis L; in particular, said rollers 27, 28, 29 are mounted on respective lever arms 19, 20, 21, hinged to a roller carrier 10, essentially in the shape of a frame, which can be removed from the outer C-shaped structure 2a, 3 of the stand in a radial direction relative to it. A similar embodiment allows the stand 5 to operate the rollers 27, 28, 29 in combination with independent adjustment thereof, as well as a substantial simplification in the operations of replacement of rollers. Due to its structural and functional characteristics, the stand of the invention finds advantageous application in rolling mills for seamless or seamed pipes, rods, bars and the like. IMAGE
