According to the requirement to the pilot mill for the cold rolling process research work, new type pilot reverse cold rolling mill is designed. Computer control system, including primary automation system, process automation system and human machine interface (HMI) system, is developed for this mill. Technological control function such as electric position control, hydraulic tension control, automatic gauge control (AGC), and process control functions such as model setup calculation, process tracking, actual data treatment are realized. This new type pilot cold rolling mill has been used successfully in several iron steel companies.

The paper describes the methods used for a study of the safety management system and culture of a cold rolling mill in a steel plant. It uses data from diverse sources which can be validated against each other and combined to produce a rich picture of the current risk control system and its shortcomings. The paper also describes the proposed improvements and what the plant chose to implement. This step also throws light on the culture of the plant.

Active disturbance rejection controller (ADRC) instead of the conventional PID controller in the hydraulic position control system is proposed to satisfy high accuracy and speed requirements in cold rolling mill. Based on the simplified model, frequency-domain analysis of the two kinds of controllers is performed. The results show that ADRC produces better performances, such as bandwidth, stability margins. Because of the extended state observer (ESO) that can estimate and compensate the tracking system in real time, ADRC reduces the dependence on accurate mathematical model, improves anti-disturbance capability of the system, and maintains good dynamic characteristics. The simulation results verified the effect of the conclusion.
