The design and implementation of a steel plate mill is discussed together with the impact on the design of process models, available measurements, available control actuators and material properties. Rolling process is a high-speed system which requires high-speed control and communication capabilities. Meanwhile, it is also a typical complex electromechanical system and distributed control has become the mainstream of computer control system for rolling mill. A high-level software design approach provides the ability to make quick and accurate modifications to both control loops and tuning constants. Control loop strategies and theoretical concepts of steel plate rolling are discussed. Performance results achieved during the startup of a steel plate mill are included.
