FLOGEN Technologies Inc. has developed an integrated Design/Decision-Making/Control/Optimization/Automation System combines several needs on supply side, on production side, on metal sales side and on financial side. It supports cost prediction and cost follow up on the energy and consumables side and is integrated with databases that manages numerous types of essays. This has been at various blast furnaces of pig iron. 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.

Paper Id: 550 [Abstract]

The application of the FLOGEN Decision Making, Control and Optimization system in an electric furnace for the production of FeSiMn alloy, made possible to simultaneously optimize electrical resistance of the furnace, reduce specific energy consumption, reduce MnO losses in the slag from and average of 14% to 5-8%, to better control of alloy specifications with much greater flexibility in using multiple and low quality raw materials. This paper will present the general features and control system as well as the main results

FLOGEN CONTOP – AN INTEGRATED DESIGN, DECISION-MAKING, CONTROL, OPTIMIZATION AND AUTOMATION SYSTEM FOR PIERCE SMITH CONVERTERS COUPLED WITH RAW MATERIALS MANAGEMENT

Paper Id: 551 [Abstract]

FLOGEN Technologies Inc. has developed an integrated Design/Decision-Making/Control/Optimization/Automation System for Pierce Smith Converters (offline and on-line) that combines several needs on supply side (in origin and from previous reactors), on production side, on metal sales side and on financial side. It supports cost prediction and cost follow up on the energy and consumables side and is integrated with databases that manages numerous types of essays. The system instantaneously makes a complete optimization of all raw materials, including limestone, silica, enriched air volumes etc, to achieve specific targets according to the needs of the company. The results indicate the possibility to decrease the amount of silica used as a flux, minimize the slag and copper blowing time, maximize the use of reverts, minimize slag volume, and decrease copper losses in the slag. The system finds the optimum of the charge among various scenarios while the main process parameters (such as bath temperature, sulfur content in the blister and copper in the slag) are calculated during the operation, providing a clearer overview of the process, and supporting the determination of slag and copper blowing end point. The presentation will describe some of these achievements. 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.
