Problems solved by technology

Neither wedges nor arcs are intended, since these parameters (if they differ from 0) complicate other process steps and in some cases make them impossible or lead to scrap

Embodiment Construction

[0055] figure 1 A rolling mill train for rolling a flat rolling stock 1 is shown. The mill is listed according to image 3 It is designed as a multi-stand rolling mill train with a plurality—usually four to eight—rolling stands 2 . A flat rolling stock 1 is rolled in a rolling stand 2 of a rolling train.

[0056] The mill train is equipped with a control computer 3 . The control computer 3 is designed such that it operates the rolling train according to an operating method with all the steps of the operating method according to the invention. The operating method according to the invention will be explained in more detail below. A corresponding configuration of the control computer 3 is brought about by the computer program 4 with which the control computer 3 is programmed. The computer program 4 can be for this purpose on a suitable data carrier 5 - for example the data carrier is on figure 1 Shown purely as USB-Memory-Stick-storage. The storage on the data carrier 5 i...

Abstract

The method involves determining a discontinued wedge (K) and / or a camber by a wedge model (7) based on a breadth (b), an average thickness (d), a temperature (T) of planar rolling goods (1), and a variable e.g. total rolling force (F), rolling force difference (delta F), position difference (delta s) and offset (V), by a controlling computer (3) in context of pass schedule calculation. The variable is varied by the computer. The varied variable is transferred to a base automation unit (8) of a rolling stand (2) so that the goods are rolled in the rolling stand according to the varied variable. Independent claims are also included for the following: (1) a computer program comprising instructions for rolling planar rolling goods (2) a controlling computer.

Description

technical field [0001] The invention relates to a method for operating a rolling mill train for rolling flat rolling stock in at least one rolling stand of the rolling mill train, [0002] - where the stand data describing the stand parameters of the rolling mill stand are supplied to the control computer for the rolling mill train, [0003] - wherein the control computer sets the parameters describing the rolling of the flat rolling stock in the rolling mill stand within the framework of the calculation of the rolling program, [0004] - where the set parameters are combined with the initial data describing the rolling of the flat rolling stock in the rolling mill stand and the stand data of the rolling stand describing what is produced when rolling the flat rolling stock in the rolling mill stand the roll gap and its asymmetry, [0005] - wherein the initial data comprise at least parameters characterizing the width, average thickness and average strength of the flat rolle...
