摘要

Abstract invention patent: method and rolling mill for rolling a rolled piece of metal to be produced in a casting process of ingot, control device and / or adjustment for a rolling mill, program code readable by machine to a control device Role and / or regulation and storage medium.The invention relates to a new method for laminating a piece of metal to be laminate (2) produced in a process of casting ingot, known as heavy plate (slab) in a rolling mill (13), in which, prior to lamination, the piece of metal to be laminate (2) has the form of a The truncated pyramid with a base area (4), a top area (6) and four lateral areas (8a, 8b, 10a, 10b)Method: during a first sequence of pass of rolling, two opposite lateral areas (10a, 10b) of the piece of metal to be laminate (2) are laminated in a first direction (R1) so that, at the end of the first sequence of pass of rolling, all areas cuts Is cross cutting (4)6) a piece of metal to be laminate (2) which are oriented transversely in relation to the rolling direction have the same surface area, the piece of metal to be laminate (2) is rotated, in particular through 90 degrees and, during a second sequence of pass of rolling, the me SMAS two opposite lateral areas (10a,10b) of the piece of metal to be laminate (2) are laminated in a second direction (R2) transversely in relation to the first direction (R1).The redistribution of the material of the piece of metal to be rolled (2) resulting from the shape of the piece of metal to be laminate (2), after the first sequence of pass of rolling makes it possible to the desired geometry defined completely automatically with high accuracy, in particular Without the use of cages of vertical lamination.
