Briquetting of Ferrous Fines – Saving Resources, Creating Value
Stefan Hötzinger, Fleischanderl Alexander – Primetals Technologies Austria GmbH, Austria

One of the global trends that are constantly challenging the iron and steel industry is related to the generation of fines, slurry, sludge and scales, summed up as ferrous by-products. The recycling of those by-products is commonly practiced in many steel plants. These materials normally cannot be used directly in the primary processes. The most common application is to add ferrous by-products which are suitable concerning chemical composition and grain size distribution to the sinter mix.
Besides addition of fines to the sinter plant, other solutions exist.
Primetals will present latest developments in the field of cold briquetting of ferrous by-products. Giving examples and results of executed project(s) of cold briquettes directly fed to the DR shaft, and other solutions for integrated steel mills.
In detail latest results of the Fines Briquetting Plant at the “goWest” direct reduction facility of voestalpine Stahl, in Texas, USA, will be shown, demonstrating the positive economic and environmental impact of this technology.
