Control and Optimization for Steel Plant Preheating Installations

The paper presents the results of the research performed by the authors on control systems and optimization for the operating process of the heating installations from the blast furnace at a steel plant. This system was developed on two relevant levels interconnected in a hierarchical control structure. The acquisition and control level using specialized microcontrollers was implemented. The supervisory level for the optimization of the combustion process was implemented on an operator console. The solution of the optimization problem represents the optimal decision, translated in real-time procedure to the acquisition and control level.
