A brief analysis of the state of control engineering techniques in rolling processes is given. The evolution of control engineering as it applies to rolling mills is described, examples of noteworthy applications are given, and the benefits resulting from the application of advanced control schemes are listed. Reasons for the differences in degree of automatic control observed in both industries are discussed.
