Robust Data Reconciliation to Determine Basic Oxygen Furnace Set-points

Autor: Julien Francken, Didier Maquin, Bertrand Bèle, José Ragot

Publikováno v: IFAC Proceedings Volumes. 42:286-291

In the steel industry, the determination of the control system set-points of batch processes is a common problem. It consists in adjusting the set-points in order to reach the given product specifications thanks to a process model. Small changes in o

Adaptive Prediction of Steel Hardness on Hot Strip Mill Using Neural Networks and K-Means Classifier

Autor: Michel Ianotto, Pierre Vienot, Jean-Luc Collette, Bertrand Bèle

Publikováno v: IFAC Proceedings Volumes. 37:125-130

The hardness prediction system we describe in this paper is part of a force model adaptation strategy for hot strip mill. Prediction is performed using a neural network just before the finisher set-up. The training database is automatically actualize

During the continuous casting of steel, several disturbances occur and affect all the parts of the caster, including the mould where the molten steel has to be stable for good quality of the final product. Especially at high casting velocities, the b
