Reducing gas circulates in a closed system and is recycled. The direct reduction process: Hot reducing gas flows through the iron ore, from the bottom to the top, according to the counterflow principle. The Oxygen content is reduced = "sponge iron" is produced. "Sponge iron" is pressed into briquettes (Hot Briquetted Iron)

HBI was developed as a product in order to enable Direct Reduced Iron to be handled, transported and stored safely. The high reactivity of DRI, i.e. the tendency to re-oxidise exothermically back to iron oxide, gave rise to. the risk of self-heating in the presence of oxygen (air) - if not controlled, the temperature of the material could ...

Main advantages of iron ore briquettes. Lower CO2 emissions. Briquettes emit less carbon dioxide than traditional agglomeration processes (pelletizing and sintering). It can reduce CO2 emissions in the steelmaking chain by up to 10%. Lower gas emissions. Iron ore briquettes reduce emissions gases such as sulfur dioxide and nitrogen oxide.

Carbon has been used for centuries to make steel, and for a good reason – it is the alloying element in producing steel from iron (Fe). Carbon (C) and oxygen (O 2) are used to provide the energy and lower the melting point and therefore, the energy required to melt the iron.So, it's a thermodynamic fact that some form of carbon is going to be required to …
