Abstract
A tension control method for a rolling stock section located between a front roll stand and a rear roll stand of a rolling train, wherein a tensioning element with an actual adjusting force is adjusted relative to the rolling stock section, so that the rolling stock section is deflected by the tensioning element by an actual deflection; the actual adjusting force and the actual deflection are determined; and a tension existing between the front roll stand and the rear roll stand in the rolling stock section is adjusted such that the actual adjusting force approaches a desired adjusting force and/or the actual deflection approaches a desired deflection.
Claims6
A tension control method for a rolling stock section located between a front roll stand and a rear roll stand of a rolling train, the method comprising
- adjusting a tensioning element with an actual adjusting force against the rolling stock section, so that the rolling stock section is deflected by the tensioning element by an actual deflection,
- keeping the actual adjusting force constant and equal to a desired adjusting force and measuring the actual deflection,
- comparing the actual deflection with the desired deflection, and
- based on a result of comparing the actual and the desired deflections, controlling at least one of the front roll stand and the rear roll stand such that the actual deflection approaches a desired deflection.
