Integration of Continuous Caster and Hot Strip Mill Planning for Steel Production 9/11/99 Integration of Continuous Caster and Hot Strip Mill Planning for Steel Production
In this paper we present a model and a solution approach for integration of steel continuous casters and hot strip mills to provide more responsive steel production at lower unit cost. We describe the production environment and survey existing methods for planning continuous casters and hot strip mills. Since these processes lie at the solid/liquid interface we use “virtual” slabs, correspondin...
متن کاملMetallurgically 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...
متن کاملSwitched system modeling and robust steering control in a hot strip mill
In this article, a robust steering control for the last phase of the rolling process in a hot strip mill is proposed. This phase, called tail end phase, may be modelled as a linear switched system. The switchings make the system unstable and the task of the tail end steering control consists in guaranteeing the safety of the industrial plant. The controller has to take into account the physical...
متن کاملTemperature Prediction in Hot Strip Mill Bars Using a Hybrid Type-2 Fuzzy Algorithm
A new learning methodology based on a hybrid algorithm for interval type-2 fuzzy logic systems (FLS) parameter estimation is presented. The new proposal consists of Back-Propagation with Recursive Least-Squares (BP-RLS) and BackPropagation with square-root filter (BP-REFIL). A system with the proposed methodology was simulated to test its capability for output surface temperature prediction of ...
متن کاملCharacterization of the Friction Conditions in the Finishing Stands of a Hot Strip Mill
The decrease in hot strength or even rolling load as strain increases in some stands of the finishing hot strip mill with no metallurgical reasons is a relatively common event. Apparently this fact is associated with modification in the tribological conditions between rolling stock and work roll surfaces due to unexpected interactions with scale. The aim of this work was to determine the values...
