02-07-2018· Sponge iron, also known as direct reduced iron (DRI) and used widely in the steel making process, resembles a honeycomb in its structure. As India has adequate coal deposits and its utilization for steel plants is considered to be of prime importance, production of coal-based sponge iron is considered as a viable option (Agrawal et al. 2000).

The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed. These pores, if filled with water, for example, can cause the iron to reoxidize with
