Title: Method and computer program for controlling a rolling process
Inventor: PAWELSKI HARTMUT
IPC: B21B37/00
Filed: 2006-11-30
Abstract: The invention relates to a method of controlling a rolling process, in which a metal strip is rolled flat by means of at least one roll. It is known from the prior art that the relative position of a "neutral point" is a measure of the current stability of a rolling process. Traditional methods of calculating the position of the neutral point represent the actual properties of metal, although only rather imprecisely, and are therefore suitable only to a limited extent for predicting the stability of a rolling process. In order to be able to more effectively control a rolling process for rolling a metal strip with regard to the actual behaviour of the metal strip, a novel method of calculating the relative position of the neutral point is proposed according to the invention, in which method in particular the plane of the yield stress ke and the hydrostatic pressure pNH at the neutral point are entered.
