Abstract or Summary
  • The relationships of the variables of a process to be controlled are expressed in a mathematical model of the process. In the case of the rolling of metal the process is described by the physics of the deformation of the metal in the roll gap. In developing the theory of rolling it is necessary to survey the field for existing theories and decide upon the theory that most nearly describes the process. The final model is in a form which shows the relationship of manipulated variables to measurable variables. The control of rolling is done by a machine, or rolling mill. From a control point of view it is necessary to study the combined behavior of machine and metal deformation to find the variables that may be used to most effectively regulate the process. A typical problem in this area is to control the output thickness to a given deviation from nominal. The machine-process equations show that output thickness is controlled readily by strip tensions and rolling speed. The mathematical model also shows which variables most effectively control the thickness and what the relationships are between changes in controlled variables and correction in output sheet thickness. Since the control of the process is the object of the investigation, the controller must be capable of working into conventional rolling mill drive equipment. This interrelationship is discussed in light of the equipment and the mathematical model.
