Abstract 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.
