SUMMARY:An analysis of sinter quality adjustments for blast furnace process optimization
DESCRIPTION:With steel market development and steel production advance, there is a historical quality degradation of iron ores which are used for sinter production and for pig iron production at blast furnace.  On the other hand, amid this scenario of mineral resources restrictions and raw materials worsening, blast furnace aims to achieve high productivity and high pulverized coal injection rates (PCR) in order to decrease operational costs. However, to sustain such results, it is necessary to ensure slag volume reduction on blast furnace lowering harmful elements input and to assure raw materials properties optimization (physical, chemical and metallurgical). Aligned with those perspectives, this work presents the discussion of industrial data obtained from an integrated steel plant in order to: evidence effects of granulometry and chemical quality of the iron ore mixture (sinter-feed) into the sintering process (permeability, density control, productivity, fuel consumption, burnt lime injection); correlate consequences of sinter chemical quality adjustments into sintering process; and, demonstrate the influence of sinter quality modifications (physical, chemical and metallurgical) into blast furnace operational performance (permeability, slag index, top gas efficiency, productivity, fuel consumption). Therefore, the improvements and discussions carried out throughout this work have allowed to mitigate effects of iron ore quality worsening into sintering process, sinter quality and blast furnace performance.
