Coiler Control in Endless Hot Strip Rolling
JFE Steel Corporation’s East Japan Works (Chiba District) started operation of No.3 Hot Strip Mill in 1995. This line was the first in the world to achieve “endless hot strip rolling.” A new Coiler Control technology was developed. Copyright 2005 IFAC
متن کاملExtraction and Classification of Operational Data for Diagnosis of Hot Strip Mill Looper Control
In these days, mechanical systems are becoming more complex and highly automated. So, there exist wide variety of demands for reliable diagnostic technology. A reliable data analysis and quantitative diagnosis method of mechanical system is necessary for the purpose. In this paper a quantitative diagnosis method for looper height control system has been developed based on neural network technol...
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...
متن کاملFuzzy Looper Control With Neural-Net Based Tuning for Rolling Mills
|Traditional looper control methods cannot deal e ectively with unmodeled dynamics and large variations which can lead to scrap runs and damages to machinery in steel industry. This paper presents the design of a fuzzy looper control with neural-net based tuning of rule-base and defuzzi cation. The e ects of various design options are discussed and practical conclusions are made. Also the resul...
متن کاملNonlinear Control of the Interstand Looper in Hot Strip Mills: a Backstepping Approach
A hot strip mill for the production of steel is a complex process where nonlinear dynamic phenomena occur and many control loops need to be tuned taking into account their interference. The control problem of the interstand tension and looper arm position is addressed in this paper. With respect to the conventional PID control approach, our investigation aims at exploiting nonlinear control tec...
