Abstract

Results are presented from tests involving the metallization of extrusion briquettes in an industrial reactor (Midrex process). The brex are made from screenings of oxidized pellets, partially metallized sludge, mill scale, and EAF dust with the use of two types of binders. The effect of the type of binder on the briquettes’ strength and degree of metallization is studied. Optical and electron microscopy are used to examine the structure of green briquettes and briquettes after their reduction.
