The system makes instantaneously 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 10%, the decrease of total consumption of charcoal (breeze and fines) by about 5%, the increase of fines injected through the tuyeres, a better control of pig iron and slag temperatures, minimization of silica addition (less charcoal consumption), a better control of pig iron composition (mainly Si and P), and complete mass and energy balance. The CONTOP system was also used to determine the annual procurement strategies and different scenarios and to determine raw material cost-based scenarios regarding productivity, fuel consumption and to develop specific useful scenarios for this purpose. 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. |
