Research in the reduction of iron ore agglomerates including coal and C-containing dust

Abstract

The Department of Ferrous Metallurgy (IEHK) since long has been investigating in the conversion of carbonaceous matter and smelting together with the reduction of iron bearing raws and materials. Actual research is being carried out in the development and improvement of self reducing carbonaceous iron bearing agglomerates. It was found that the kinetics of known reduction processes are transferable to the new agglomerates with respect to new phenomena such as alteration of shape and volume. The examined agglomerates are partly charged in new so-called alternative processes, and shaft furnaces, e.g. Tecnored and OxiCup process. These processes are currently being transferred from pilot to industrial plant scale. IEHK is partner in the ongoing research of those processes. © 2005 ISIJ.
