Resumen

Results of calculation for BF of OJSC “MMK” operation with high proportion in the charge of non-fluxed pellets of Sokolov Sarbai Mining and Processing Production Association with different content of local sinter are presented. It is shown that increasing the share of non-pellets (60%) loaded in charge to achieve the required basicity of BF slag it is necessary to add limestone into the charge. To reduce the weight of loaded raw limestone, it is necessary to produce sinter of high basicity. Increasing proportion of pellets in loaded charge leads to decrease of magnesia concentration in the blast-furnace slag. To increase the concentration of magnesium oxide in the slag at sinter production it is advisable to use the combined basic flux consisting of 70% normal and 30% dolomite limestone.
