Outline of Strip Rolling Technological Control Theory

Zhang Jinzhi

Strategic Study of CAE 2001, Volume 3, Issue 4, Pages 46-55

Abstract:

Classical rolling theory, which is based on the law of the lowest resistance,the condition of constantThis system reflects only the static law of rolling process,so it is necessary to control dynamic rollingA new theory system, which is based on fundamental rolling technology control theory, is set up.Its main content included：the tension theory system in continuous rolling, which reflects the negativefeedback effect of tension, is set up;disturbance survey problem is settled in gauge control process

Keywords： continuous rolling process control tension in continuous rolling gauge control shape stiffness springequation for rolling mill comprehensive equal reserves for load distribution
