摘要： The present invention relates to a system and method for rolling a seamless tube. The plant comprises a main rolling mill with adjustable rolls for mandrel-rolling a semi-finished tube. The plant also comprises a fixed-roll extracting/reducing mill positioned downstream of the main rolling mill. The extracting/reducing mill is designed to extract the semi-finished tube from the mandrel and reduce its diameter to a predetermined value close to that desired for the finished tube. Finally, the plant comprises a adjustable-roll sizing mill. The sizing mill is positioned downstream of the extracting/reducing mill. This sizing mill is designed to adjust the radial position of the rolls and define the diameter of the outgoing tube.

At least one rolling station comprises a fixed structure 40, a roll-holder cartridge 24 and three actuators 32. The cartridge is connected removably to the fixed structure and comprises three rolling rolls 26. The rolls are movable radially and rotatable about three respective axes arranged at 120° from each other. The three actuators are mounted on the fixed structure and comprise pistons 50 movable along respective radial axes t arranged at 120° from each other. Each of the actuators is able, during use, to act on one of the rolls so as to impart a radial force suitable for rolling the article 44. The rolling mill 20 according to the invention is characterized in that the three actuators are of the single-stroke type and are arranged so that, when the pistons of two actuators are completely retracted to the end-of-travel stop of the working stroke, a path P is created free from obstacles and parallel to the axis of the third actuator. The path P which is created is such that allows the cartridge to pass out laterally on the opposite side to that where the third actuator is situated.

摘要： The invention relates to a rolling mill defining a rolling axis and comprising rolling stations. At least one rolling station comprises a fixed structure, a roll-holder cartridge and three actuators. The cartridge is connected removably to the fixed structure and comprises three rolling rolls. The rolls are movable radially and rotatable about three respective axes. Three actuators of the single-stroke type are mounted on the fixed structure and comprise pistons movable along respective radial axes to impart a force on the rolls for rolling an article. Three gearmotors provide the rolls, by means of spindles, with the torque for feeding the article along the rolling axis. When two pistons are completely retracted, a path is created free from obstacles allowing the cartridge to pass out laterally. Then, one spindle may be subject to a rotation-translation to be removed from the path, the respective gearmotor being fixed on its base.

摘要： The present invention teaches rolling a seamless tube, typically with a large diameter. The system comprises a furnace for heating billets produced by continuous casting. The system comprises a piercing mill for longitudinally piercing the heated billets to obtain a pierced blank. The system comprises an expanding-elongating mill for expanding the pierced blank diameter and for elongating the pierced blank to obtain a semi-finished tube. The system comprises a continuous main rolling mill with adjustable rolls for mandrel-rolling a semi-finished tube.
