摘要： A rolling mill for the production of rails comprising a reversible intermediate working section (3) which receives broken down bars from an appropriate upstream break down rolling station (2) and passes them to a downstream finishing station (4). The intermediate working section (3) comprises a first (30) and a second universal stand (32), a high edging stand (31) placed between the first and the second universal stands (30, 32). The three stands (30, 31, 32) are placed at such a distance between each other that the bar can be simultaneously held in all three said stands (30, 31, 32) during rolling. A method for the rolling of rails with such a plant comprises the following operations in order: a rolling passage (U1) in the second universal stand (32); a rolling passage (E1) in the high edging stand (31); a rolling passage (U2) in the first universal stand (30).

摘要： A universal rolling stand with control of the space between the rolls comprises a pair of horizontal rolls and one or more vertical rolls with respective chocks, positioning housings and a guide for the chocks with adjustment tie rods (6, 7, 6', 7', 18, 18', 19, 19') anchored on one side to the housings and acting on the chocks for the adjustment and positioning of the rolls. Adjustment is performed by means of hydraulic capsules (8, 8', 9, 9', 20, 20', 21, 21') with two hydraulic chambers with dual actuation effect and a double stem at the ends of each tie rod.
