METHOD AND ROLLING TRAIN FOR ROLLING A ROLLED STOCK PRODUCED IN AN INGOT CASTING PROCESS, CONTROLLING AND/OR REGULATING DEVICE FOR A ROLLING TRAIN, MACHINE-READABLE PROGRAM CODE FOR A CONTROLLING AND/OR REGULATING DEVICE AND STORAGE MEDIUM

摘要

The invention relates to a novel method for rolling a rolled stock (2) produced in an ingot casting process, known as a slab, in a rolling train (13), wherein, before the rolling, the rolled stock (2) has the form of a truncated pyramid with a base area (4), a top area (6) and four side areas (8a, 8b, 10a, 10b), in which method: during a first rolling pass sequence, two opposite side areas (10a, 10b) of the rolled stock (2) are rolled in a first direction (R₁) in such a way that, at the end of the first rolling pass sequence, all of the cross-sectional areas (4, 6) of the rolled stock (2) that are oriented transversely in relation to the rolling direction have the same surface area, the rolled stock (2) is turned, in particular through 90°, and, during a second rolling pass sequence, the same two opposite side areas (10a, 10b) of the rolled stock (2) are rolled in a second direction (R₂), transversely in relation to the first direction (R₁). The redistribution of the material of the rolled stock (2) that results from the form of the rolled stock (2) after the first rolling pass sequence makes it possible for the desired geometry to be set fully automatically with high precision, in particular without the use of vertical rolling stands.
