Self-reducing technology has shown a process that presents advantages due to the flexibility of using different low-cost raw materials (fines, dusts, sludge, etc.) and low investment cost, resulting in a competitive one. The main technical advantage is the rate of reaction due to closeness of reactants resulting in a process with high productivity. The development started at MTU (Goksel 1977), and presently there are many processes based on these principles: PTC process (Goksel et al. 1991), Tecnored process (Contrucci and Spearman 1997), Itmk3 (Tsuge 2002), Fastmet (McClelland 2002), Inmetco (Koros 2001), and others. This paper discusses the behavior of self-reducing pellets usable in the self-reducing processes. Mechanical properties such as cold strength, strength after heating, decrepitation, and swelling are analyzed.
