Sponge iron making is a process in which iron ore lumps (typically 5mm-18mm size) are tumbled with a 'select' grade of iron-coking coal little dolomite inside an inclined rotary kiln and control combusted in the presence of air for about 12 hours before the products are air cooled, magnetically separated, screened and size wise in finished ...

The BOS process uses pure oxygen, injected by a lance, for refining the relatively impure hot metal (and scrap is used for temperature control). The electric arc furnace uses primarily electrical energy to supply heat to melt scrap steel, sponge iron, or mixtures of scrap and other iron units. Compared to the BOS process, the EAF requires

The substitution of scrap by sponge iron has some limitations depending on the furnace operating conditions. Only 20% to 30% of sponge iron can be used in the furnace charge when feeding is done in batches. The proportion of sponge iron in the charge can however be increased to 40-50% by providing continuous feeding arrangements.
