Multivariable controller design for a hot rolling mill

Speed Control of an Experimental Hot-rolling Mill Using Generalised Predictive Control

The application of Generalised Predictive Control (GPC) for an experimental hot-rolling mill is presented in this paper. GPC has been implemented to provide the mill with good speed control and regulation when steel and aluminium hot-rolling experiments are carried out. Using an identification mechanism, GPC first estimates the mill’s model and predict the future behaviour of the rolling speed ...

Slab curvature compensation in a hot rolling mill by means of fuzzy control

In the flat products steel industry, the hot rolling mill transforms the incoming slabs in a thin coil which then can be processed to obtain the final products. Thickness is reduced by pulling the plate between two parallel rolls while moving the upper work roll. The effect of uneven thickness at both sides can produce deviations in the longitudinal direction of the slab, which have to be manua...

Design, Implementation and Testing of an Intelligent Knowledge-based System for the Supervisory Control of a Hot Rolling Mill

This paper describes the design, implementation and testing of an intelligent knowledgebased supervisory control (IKBSC) system for a hot rolling mill process. A novel architecture is used to integrate an expert system with an existing supervisory control system and a new optimization methodology for scheduling the soaking pits in which the material is heated prior to rolling. The resulting IKB...

Metallurgically Consistent Determination of Steel Hot Strength Using Process Data from Hot Strip Mill Rolling

It is not rare to observe an inverse relationship between hot strength determined from rolling load of the finishing stands of the hot strip mill and strain. This situation was already described in the literature and is explained by the use of inverse rolling load models that assumes sticking friction in the determination of hot strength. The aim of this work was to show that this “work softeni...
