Sintering, Ore mixtures, Iron ores, Blast furnaceAbstract
Various iron ores, fluxes and coke, were used to prepare four ore mixtures with different proportions of these minerals. With each mixtures a series of sinters were produced in the pilot plant. Each one of the sinters was characterised by: chemical and granulometric analysis; degradation test on the sinter during reduction in the blast furnace, (RDI test); cold resistance test, (Tumbler Test); reducibility test; determining of softening and melting temperatures; and the determination of the structure of the sinter by electron microscopy. T he conditions of the mixtures and the operational parameters for obtaining the optimum quality of the sinters were established.
