The work roll bending control system of the hot plate rolling mill

This article describes the kinds of thickness deviation arising during hot plate rolling process. The ways to determine thickness deviation by measuring the thickness of the sheet at various points are shown. The reasons of rolls bending under the rolling pressure are found. Examples of using the different structures for the implementation of the roll bending system are shown. The results of the system were considered in the hot rolling plate mill conditions.
