R. China) Abstract: The integrated automation system consisting based on Rockwell Automation and intelligent control of three layers: Intelligent Optimization Control, Process Control and Process Management is developed to fit the characteristic and requirement of the shaft furnace roasting process and optimization target of Magnetic Tube Recovery Rate (MTRR) is achieved. The technology performance of Rockwell Automation products is introduced. The structure, functions and MTRR based control strategy of this system are discussed. The system proposed in this paper has been successfully applied to the roasting process of Minerals Processing Factory of an Iron and Steel Company to realize process optimal control, process optimal operation and process optimal management. It has been proven to provide benefits to this minerals processing factory and reliability of advanced Rockwell’s technology at factory automation application. Key words: Shaft Furnace Roasting; MTRR; Rockwell Automation; Integrated Automation System; Intelligent Optimization
