نویسندگان
چکیده
The paper summarizes the creation of a robust online grain size gauge for hot strip mill. A method and algorithm calculating from measured ultrasonic attenuation is presented. This new self-calibrating, does not rely on geometrical reference sample can cope with effects diffraction attenuation. model based 52 quenched samples more than 23,000 laser ultrasonics shots has correlation coefficient R2 0.8. Typical measurements mill calculated versus length are presented couple steel strips.

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 کاملThe Thermoelastic Surface Strip Source for Laser-generated Ultrasound
The vertical ultrasonic surface displacement generated by a laser-induced, thermoelelastic, rectangular surface strip source is formulated. The main features of this source, ultrasonic rise times comparable to those of the generating light pulse derivatives, and a large amplitude, double-pulsed waveform, are advantageous for ultrasonic spectraland time-domain measurements for nondestructive mat...
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 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...
