Abstract

See full text

A DRI product and method of forming the DRI product. DRI is formed from a reducing process, and thereafter the DRI is subjected to another heat treatment that produces a DRI product. The DRI product formed has a metallic shell around at least a portion of a DRI core. The heat treatment may be delivered through the use of a plasma torch, a gas burner, an oven, or any other like heat source. The heat treatment may heat the DRI for a fraction of a second and quickly cool the DRI in order to melt the surface and form the metallic shell without vaporizing a significant portion of the DRI and without losing a significant amount of the latent energy in the DRI.
