MAKING MORE EFFICIENT USE OF SOLID FUEL IN TWO-LAYER SINTERING

摘要

Results are presented from laboratory studies of the sintering of a two-layer charge in which the solid fuel is separated into different fractions. It was established that a reduction in the top layer's content of the -0.5-mm fraction from 45% to zero is accompanied by a decrease in the unit productivity of the sintering machine and increases in the output of sinter and its strength characteristics. The indices of the sintering operation and sinter quality remain the same as in the standard technology when fuel content is decreased from 7.5 to 7.1-7.2%. Introduction of the technology that was developed will makes it possible to decrease the unit consumption of solid fuel for sinter production by 4%.
