Zusammenfassung: | 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 (U 1 ) in the second universal stand ( 32 ); a rolling passage (E 1 ) in the high edging stand ( 31 ); a rolling passage (U 2 ) in the first universal stand ( 30 ). |
