Resumo
Of the large number of byproducts in the form of dusts, sludges, flakes, slag, fines, and others generated in the iron and steel industry, we can distinguish those that can be recycled directly in a sintering plant from others that are more difficult to recycle due to their specific characteristics, such as excessive moisture, very fine or coarse particle size, and chemical elements that are harmful to the processes in which they are used. Recycling through the production of cold agglomerates by vibropressing offers the possibility to obtain a product that could be suitable for charging into steelmaking reactors. The design and selection of materials that would take part in the mixture to be compacted must be consistent with the strict specifications required for each process. This paper presents the vibropressing agglomeration methodology as a viable technique to obtain briquettes that can be used as part of the charge in steelmaking reactors.
