Abstract
This chapter presents an overall view of conventional control concepts for the tandem cold metal rolling process to serve as a background for the chapters which follow on advanced control. While the emphasis is on automatic control of strip thickness and interstand tension, the control of the process in the areas of eccentricity compensation, strip flatness, and threading of the mill also is briefly addressed. Included in each area are examples of typical control techniques, most of which are taken from actual industry applications.

Notes
- 1.
The terms “shape” and “flatness” sometimes are used interchangeably to imply the same condition of the strip. For purposes of this work, this understanding is adopted herein. More about this is considered in Section 3.6.
