Estudo do estado da arte da influência dos tipos de aglomerantes nas propriedades mecânicas de aglomerados siderúrgicos.

Abstract

Although iron is one of the most abundant elements in the earth's crust, it is mostly in the form of oxides, normally found in mineral reserves. Over time, reserves with higher grades are becoming scarce and ores with higher degrees of impurities are being explored. Greater processing aimed at reducing impurities results in the generation of finer ores. With the need to give this fine concentrate ore adequate dimensions, the use of agglomeration processes has become more and more frequent as the world demand for steel has increased. Considering that these agglomerates must have mechanical resistance to handling, storage and high temperatures, one of the most important aspects related to these materials, which are binders, was studied in the present work. The study was carried out through literature analysis regarding the mechanical properties of agglomerates that made use of different binders. The collected data were analyzed and presented in this work in nine chapters, with three of them being destined to ore agglomerates, to self-reducing agglomerates and to combustible agglomerates.
