Abstract

This invention deals with methods for controlling the rolling process using rollers. Which long metal strips will Is rolled flat using at least one roller. It is known from the Renaissance that the relative position of the so-called neutral point represents a measure for the current stability of a process. Roll using a roller However The traditional method for calculating the position of a neutral point would It simply represents the true properties of the metal, somewhat inaccurate. And therefore there is Conditionally suitable for obtaining information on the stability of the rolling process using rollers in order to better control the rolling process using rollers. For rolling metal long strips by Consider the true properties of the long metal strip. This invention presents a new method for computation. The relative position of the neutral point Which in particular The strain at the jet lag ke and the PNH hydrostatic pressure at the neutral point are included in the calculation [Fig. 2].

1. Methods for controlling the rolling process using rollers. In which a long metal strip (100) is rolled out using at least one roller (200). It consists of the following methods. Detecting the relative position (N) of the neutral point in the arc in contact between the long metal strip (100) and the roller (200), and, if desired, stabilization of the rolling process is performed using the roller depending on the position. Zeta (N) of the neutral point By interfering with the rolling process using rollers with appropriate measures With a special characteristic that
