How to Use Reduced Iron Powder as Sintering Assistant Iron-Containing Raw Material

1. The reduced iron powder is a good raw material for iron-containing raw materials for sintering. Theoretical calculations show that 1kg of FeO can be radiated by 1973 joules by oxidizing Fe2O3. After the iron oxide scale is added to the sintering mixture, the sintering process is high due to the high temperature, so that the sintering productivity is increased and the consumption of solid fuel is reduced.

2, production practices show that 8% of the iron oxide skin can increase production by about 2%. Baosteel uses the iron oxide skin as an auxiliary material to add iron oxide skin to the mixed ore. On the one hand, the relative grain size of the iron oxide skin improves the permeability of the sinter layer; on the other hand, the iron oxide skin emits heat during the sintering process. This reduces the solid fuel consumption.

3. Since the reduced iron powder itself is powdery, and its microstructure is very loose, its surface area is extremely large.
