Abstract

The ore consolidation process is a thermal process and it happens at the temperatures of the ore melting beginning, allowing the ore grains, additives and fluxes to be connected into a solid piece of sinter. The amount of carbon in the sinter mixture and the FeO content of the produced sinter affect the mechanical resistance of the sinter. Indicators of mechanical resistance of sinter are very important for evaluating the metallurgical value of sinter. How much of the sinter is grounded during transport to the blast furnace and in the furnace depends on the mechanical resistance. The amount of high-dust, the gas permeability of the furnace, and thus the furnace productivity and fuel consumption depends on the amount of fine fractions in the furnace.
