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...
متن کاملIntegration 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 کاملContribution rate plot for nonlinear quality-related fault diagnosis with application to the hot strip mill process
In this paper, a nonlinear fault diagnosis scheme is established for the hot strip mill process (HSMP). In HSMP, the faults affecting quality index are denoted as quality-related faults, which should be taken care as soon as possible. Projection to latent structures (PLS) is a basic model for quality-related fault detection in linear processes. In the presented work, a total kernel PLS (T-KPLS)...
متن کاملAnalysis of Work Roll Thermal Behavior for 1450mm Hot Strip Mill with Genetic Algorithm
Work roll thermal contour is one of the important factors for roll contour design and configuration in hot strip rolling, for which the temperature field calculation is a critical factor. To realize the work roll thermal behavior for 1450mm hot strip mill, the temperature field and thermal contour calculation model was built with finite different methods, and the genetic algorithm was introduce...
متن کاملNonlinear Looper-tension Control for Hot Strip Finishing Mill Using Feedback Linearization
Abstract: This paper studies on the design of a nonlinear controller for the looper-tension system in hot strip finishing mills using a static state feedback linearization and an ILQ(Inverse Linear Quadratic) Optimal Control. Nonlinear dynamic equations of the looper-tension system are analytically linearized by a static feedback linearization algorithm with a compensator. A nonlinear controlle...
