Method for rolling and/or heat treating metal products

Abstract

The invention relates to a method for rolling and / or heat treating a metal product (1), wherein the product is subjected at a first position (2) to a rolling operation regulated by a regulating device (3) , wherein the product ( 1 ) is measured at the second position ( 4 ), the product ( 1 ) is subjected to further processing operations at the third position ( 6 ), and at the fourth position ( 7 ) a predetermined quality Product (1). In order to improve the quality of the produced strip, the invention provides that the method has the following steps: a) measuring the value of the material property (IW) at the second position (4); b) measuring the value of the material property (IW) at the second position (4); The measured value is transmitted to the regulating device (3), the measured value is compared with the value (SW) stored in the regulating device (3), and if the measured value deviates from the stored value (SW), Adjusting the parameter (PP1); c) measuring the value of the quality material property (Q) at the fourth position (7); d) comparing the measured value with the stored value, and if the measured value is the same as the stored value If the difference exceeds the permissible tolerance, measures for influencing the quality parameter performance (Q) are initiated.

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...
