Abstract

A rolling mill for rolling pipes on a mandrel (40) is formed by an alignment of rolling units according to the invention; each rolling unit comprises an outer annular structure (2) formed by at least two plate-shaped elements (3) connected rigidly to one another and housing a roll carrier (10) on which the rolling rolls (27, 28, 29), supported by respective pivoting lever arms (19, 20, 21), are disposed. Each roll carrier (10) can be removed transversely from its rolling unit which, for this purpose, is provided with guides (15) in addition to a loading-unloading device (SO) on which the removed carrier is placed. The outer annular structure (2) enables the rolling unit and the corresponding rolling mill better to withstand the radial stresses produced during working, the replacement of the rolls and of the respective carriers (10) at the same time being simplified by virtue of their lateral removal.
