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 constantvolume and the condition of equal flow per second,has formed a fairly integrated rolling applied technologyThis system reflects only the static law of rolling process,so it is necessary to control dynamic rollingtheory, classical rolling theory based on mechanics took the lead before the establishment of springA new theory system, which is based on fundamental rolling technology control theory, is set up.
