FLOGEN Decision Making, Control, and Optimization system has been applied in Waltz Rotary Kiln that produces Zn from steel dust. This resulted in simultaneously reducing the specific coke/coal consumption, maximizing Zn yield, decreasing Zn losses in the slag, minimizing accretions and balls inside the furnace, increasing the operational time without stoppages and enabled greater flexibility in using multiple raw materials. This paper presents some of the above results along with the most recent developments of application in other processes

Paper Id: 487 [Abstract]

FLOGEN Decision Making, Control and Optimization system has been applied to the production of FeSiMn alloy production in an electric furnace. This resulted in simultaneously reducing the specific energy consumption, decreasing Mn losses in the slag, better control of allow specifications and greater flexibility in using multiple raw materials. This paper will present the general features and control system as well as the main results

FLOGEN Contop Design, Decision-Making, Control, Optimization and Automation System Applied at Blast Furnaces

Paper Id: 479 [Abstract]

FLOGEN Technologies Inc. has implemented and commissioned FLOGEN CONTOP, a Design/Decision-Making/Control/Optimization/Automation System at various blast furnaces of pig iron producers in Brazil. The system instantaneously makes a complete optimization of all raw materials, including limestone, silica, air and oxygen volumes, in order to achieve specific targets according to the needs of the company. The main achievements of the implementation of the FLOGEN CONTOP system were the increase of the pig iron production by about 14% and the decrease of total consumption of charcoal (breeze and fines) by about 4%. Additionally, fines injected through the tuyeres were decreased, temperature and composition of slag and pig iron (including Si and P) were better controlled and silica addition as a flux was minimized. An overall instantaneous mass and energy balance helped fix various mechanical and procedural problems in the plant. CONTOP system was also successfully used to determine the annual procurement strategies by predicting various raw material cost-based scenarios related to productivity and fuel consumption in short- and long-term future. CONTOP increased productivity and reduced cost up to the highest designed limit of the technology. CONTOP also changed the way of operating from a reactive wait-the-lab-results-approach to a proactive forecast-and-act approach.
