The Partial High Point and the Influence to the Hot Strip Profile Control

Abstract:

Article Preview

The partial high points, always appearing when the hot strip is being rolled, not only negatively influence the quality of the hot strip, but also make a long term effect on the profile control. Via quantifying and separating the partial high points and analyzing the calculation of the strip crown, we can obtain the calculation method of the error resulted from the high points; then, on the basis of the way that the high points affect the profile and flatness control system, we can present some tactics to lessen the high points’ effect.
