Sponge iron is used as a substitute for scrap in electrical arc and induction furnaces. It’s an important raw material for making high quality steel, especially because of the shortage of expensive melting scrap.
Download PDFImproved Steel Quality: Sponge iron with high Fe(m) and Fe(t) contents produces steel with better mechanical properties, such as strength, toughness, and ductility.
Reduced Energy Consumption: Sponge iron with high Fe(m) and Fe(t) contents requires less energy to melt and process in the steelmaking furnace
It has high Fe content, ranging between 78-82%
Sponge iron generates minimal dust during handling
Sponge iron is made by reducing iron ore with carbon at around 1100 degrees Celsius. This process can use a variety of methods, including red-ox reactions, partial oxidation of coal, reforming methane, and partial combustion of natural gas..
