ArcelorMittal Tubarao hot skin pass - Flatnessimprovements in thin gauges
Published online by Cambridge University Press: 01 May 2008
Abstract
The main purpose of ArcelorMittal Tubarao skin pass is to improve the flatness in thin gauges hot rolled strips. Since the start-up in 2002 several actions have been implemented and a consistent evolution of quality and process control has been reached: The philosophy of production scheduling along the rolls campaign to minimize the effect of roll wear; The definition of optimum target elongations to keep as constant as possible the roll forces and avoid roll bending changes; The automation of bending forces control according to characteristics of the strip and the rolls.
