Abstract:

Results are given for calculation of blast furnace operation with a high proportion of Sokolovo-Sarbaiskii Metallurgical Production Association unfluxed pellets with a different content of local agglomerate. It is shown that with an increase in the proportion of unfluxed pellets (up to 60\%) in a loading charge in order to achieve the required blast furnace slag basicity charging limestone into the furnace is necessary. In order to reduce the weight of loaded ``raw{''} limestone, it is necessary to produce agglomerate with high basicity. As the proportion of pellets increases in a loaded charge, there is a reduction in blast furnace slag magnesia content. In order to increase slag magnesium oxide concentration, it is expedient during agglomerate preparation to use a combined basic flux consisting of 70\% normal and 30\% dolomitized limestone.
