Stiff Vacuum Extrusion for Agglomeration of Natural and Anthropogenic Materials in Metallurgy

Abstract

Recently developed concept of stiff vacuum extrusion (SVE) agglomeration for iron and steel making helps to innovate the briquetting technology and make it competitive with sintering. The results of the R&D in this field show that extrusion attributes very specific properties to the agglomerated products-BREX (extrusion briquettes), which favors their wide utilization in metallurgy-among them are quick strengthening of the BREX, their high hot strength, very low self-cost, and maintenance values. A set of the successful projects have been realized in iron making, ferroalloy production, and direct-reduced iron (DRI) production.
