Abstract

A method for producing a metallic strip or sheet, in which the strip or sheet is rolled in a multi-stand rolling mill and is discharged downstream of the last roll stand of the rolling mill in a conveying direction. The strip or sheet is cooled in the multi-stand rolling mill and/or downstream of the rolling mill as viewed in the conveying direction, wherein a temperature of the strip or sheet is measured upstream of the last roll stand of the rolling mill as viewed in conveying direction. Based on this measured temperature, a temperature for the strip or sheet at the exit of the last roll stand of the rolling mill is then determined by calculation with the aid of a temperature calculation model, with which further temperature processes of the manufacturing method can be controlled or regulated after a comparison with a predetermined reference value.
