Abstract:
The present work originates from a cooperative research program linking PUC-Rio University and a Brazilian integrated steelwork company, dealing with the use of self-reducing agglomerates. Aiming the utilization of residues generated in the integrated steelmaking plant, several types of self-reducing briquettes were formulated. In this communication, a set of results obtained through two routes are presented: firstly, the briquettes solid reduction and their correspondent metallization, monitoring the composition of the exhaust gases in a CO gas line. Secondly, using a properly prepared and instrumented induction furnace, investigating the metallization degree and the effect on the melting steel temperature, after adding the briquettes into the induction reactor. The results showed the sustainability nature and the technical viability of both methods, i.e, the solid state recycling route and the use of composite briquettes as an alternative cooling material for steel baths.
