Resumo
The metallic burden reduction behavior is a prerequisite for stable blast furnace operation. Because of this, it is fundamental importance its knowledge, according to the characteristics of each material. In this paper are presented the results of prereduction behavior by one type of sinter and two types of pellets, and its effect on the region of the cohesive zone. The results indicated that a low reduced burden leads to decreased softening temperature, extending the zone of softening and melting, with consequent increase in pressure drop. In other words, the characteristics of prereduction of metallic burden may determine the blast furnace productivity, fuel consumption and operational stability.
