Hot Rolling Mill Roll Eccentricity

Rolling Mill Tutorial - Part 5. Before continuing, make sure you have read Section 21.11 Linear Optimal Filters. Observers. To estimate roll eccentricity, we view the output of the BISRA gauge which is h e as the eccentricity e plus some noise. Before we can use an observer to estimate the roll eccentricity, we need to model it.

Strip Thickness Control Of Cold Rolling Mill With Roll

In rolling mill, the accuracy and quality of the strip exit thickness are very important factors. To realize high accuracy in the strip exit thickness, the Automatic Gauge Control AGC system is used. Because of roll eccentricity in backup rolls, the exit thickness deviates periodically. In this paper, we design PI controller in outer loop for the strip exit thickness while PD controller is.
