Method for rolling and/or heat treating a metal strip

Abstract

The invention relates to a method for rolling a metal product (1), wherein the metal product is subjected to a rolling operation at a first station (2), which rolling operation is controlled by a control device (3), wherein the product (1) is subjected to a measurement at a second station (4), wherein the product (1) is subjected to a further processing operation at a third station (6), and wherein the product (1) is in a specified quality at a fourth station (7). In order to increase the quality of the produced strip, the invention provides that the method has the following steps: a) measuring the value of a material property (IW) at the second station (4); b) feeding the value measured at the second station (4) to the control device (3), comparing the measured value with a value (SW) stored in the control device (3), and adjusting a parameter (PP1) if the measured value deviates from the stored value (SW), c) measuring a value of a quality material property (Q) at the fourth station(7); d) comparing the measured value with a stored value, and initiating a measure to influence the quality material property (Q) if the measured value deviates from the stored value beyond a permissible tolerance.

Description

technical field [0001] The invention relates to a method for rolling and / or heat-treating a metal product, in particular strip, wherein said product is subjected to a rolling and / or heat-treating operation at a first location, said rolling and / or The heat treatment operation is controlled and / or regulated by control and / or regulating means, wherein the product is measured by means of measuring means at a second position after the first position, the product is at a third position after the second position It is subjected to another processing operation and a product of preset quality is obtained at a fourth location after the third location. Background technique [0002] The predetermined quality can be, but need not necessarily be, the final quality of the product, wherein the product is in particular a strip or a plate. The sequence of positions is to be understood in particular along the conveying direction or in the sense of a production sequence. In connection with th...
