Production of Iron by Reduction with Gas

Scrap or recycled steel is a basic material for the electric steelworks. The problem is the shortage of this material in certain regions of the world due to the construction of new electric steel plants and the simultaneous break down of blast furnaces. An alternative to produce high-quality synthetic scrap free of residual impurities is the installations of direct reduction. In this chapter, we describe the different process of direct reduction of iron ore: Midrex, HYL-III, Finmet, Fastmet, and Iron Carbide, and we complement this description with several solved exercises.
