摘要： A rolling stand includes a roller-carrier substantially in the form of a ring-shaped body having the rollers journalled on its interior; the roller-carrier is slidable along a longitudinal rolling axis L between an operative position occupied during the rolling process, where it is locked inside an outer structure of the rolling stand, and a non-operative position where it is removed from the structure. Provided within the rolling stand are guide means for guiding the roller-carrier movement along the axis L and means of locking the roller-carrier in the operative position.

摘要： A stretch-reducing mill comprises a plurality of rolling stands laid side-by-side between an input stand and an output stand. A first group of stands adjacent to one another is next to the input stand and a second group of stands adjacent to one another is next to the output stand. The first group of stands is operated through a differential drive with two motors; the second group of stands is driven by independent single motors.

摘要： The invention relates to a rolling mill for sizing tubes or cylindrical bodies such as bars, rods and so on, and is intended for the iron and steel industry. The rolling mill is made up of a multiplicity of fixed three-roll rolling units, i.e. of the type known per se in which the position of the rolls cannot be adjusted under load and they are kinematically connected to each other so as to be set in rotation simultaneously, downstream of which are a multiplicity of adjustable three-roll rolling units. In the latter units the position of the rolls can be adjusted even under load and the purpose of these is to carry out the finishing of the work that is to be sized. The invention enables excellent use to be made of the characteristics of strength of the fixed units and of accurate working of the adjustable units, with the result that it is possible to build an inexpensive but high-performance rolling mill. In a preferred embodiment, in the adjustable units the rolls are mounted on lever-type arms pivoting in planes lying radially with respect to the rolling axis.

摘要： A mandrel holder head with release/fastening device of the mandrel for rolling metallic tubes comprises a mandrel holder (1) which accommodates within an internal seat a half collar (2) of externally cylindrical shape through an opening in the side wall. In the internal seat are accommodated both an end part (52) of the mandrel shank and the half collar (2) through the opening. The half collar has an internal cavity with a second longitudinal side opening which accommodates a second part (51) of the shank of diameter smaller than that of the first part (52). The half collar is divided along an axial direction into two cylindrical parts (21, 22) which have different diameters. The locking member (30, 31) of the half collar (2) holds it in the mandrel holder (1) seat in working conditions, while allowing shank release with an axial movement in locked conditions.

摘要： In order to facilitate side extraction of the roller holder cartridge (3) in a rolling mill stand (100), the strokes of the hydraulic capsules needed to take the pistons of the same clear from the trajectory traveled by the roller holder cartridge (3) during the extraction of the same from the rolling mill, may reach values indicatively between 150 and 400 mm, values which can negatively affect response times of the position control system of said capsules (4″). In order to continue to apply the same capsule control methods but with a considerably more dynamic system capable of rapidly and accurately reacting to sudden changes of pressure, the servo valves in the control circuits are of the four-way type, instead of the three-way type.
