Recovery of powdery ferrous waste through pelleting

摘要

In the steel industry, beside of primary products, results amount of powder waste which creates problems for recovery on the first step, due to in corresponding granulometric composition and on the other step due to the content of heavy metals in their composition. The powder waste used in experiments in this paper it was processed by pelleting process, following a strength process of pellets using a lot of diagrams, modifying the heating time of their. The results of experiments were processed in Excel program, resulting in a series of graphical and analytical correlations between the diameter of pellets and compressions strength, being presented for each variant.
