CAMBER AND WEDGE COMPENSATION IN HOT STRIP ROLLING

摘要

In this paper the possibility of exploiting in a closed-loop framework a camber sensor with advanced control techniques for the camber compensation at the roughing stand of a hot strip mill is explored. Model issues and new control techniques are discussed. In particular we show how it is possible to achieve a prompt annihilation of the camber deviation by the introduction of a suitable model and Kalman filtering concepts.
