Topic: 2Abstract:
One of the main parameters in the gas flow distribution in a Blast Furnace is the size distribution. In the CSA Blast Furnaces, the sinter fines extraction was improved through sieves adjustments in the stock house, and a better gas flow control into the Blast Furnace was observed. In this paper, it is possible to evaluate the influence of the improvement in the sinter screening process in the BF gas flow, and its impact in the reduction of thermal load standard deviation on the wall in the upper part of the Blast Furnace. By BF stable gas flow, an increase in the top gas efficiency and a decrease in the variation of the thermal load on the wall were observed. Fuel rate and Hot Metal production were also improved as a consequence of better gas flow distribution into Blast Furnace.
