Outline of Strip Rolling Technological Control Theory
Classical rolling theory, which is based on the law of the lowest resistance,the condition of constant volume and the condition of equal flow per second,has formed a fairly integrated rolling applied technology science system by means of experiment and deduction. This system reflects only the static law of rolling process,so it is necessary to control dynamic rolling process by drawing high and new technology such as cybernetics, information theory and computer science into the system.During the history of rolling theory, classical rolling theory based on mechanics took the lead before the establishment of spring equation, after that the rolling process control theory based on mechanics and cybernetics took precedence. In this paper,the concept of technological control theory is put forward. A 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 negative feedback effect of tension, is set up;disturbance survey problem is settled in gauge control process;shape theory system, which resembles gauge control theory,by defining dual parameter,is established.
continuous rolling process control / tension in continuous rolling / gauge control / shape stiffness / spring equation for rolling mill / comprehensive equal reserves for load distribution
