"DEPHOSPHORIZATION OF STEEL PRODUCED FROM SPONGE IRON .

In the primary route of steel making iron ore is used as raw material. In the first stage iron ore is melted in a blast furnace to produce hot metal, and in second stage this hot metal is moved to a steel making shop to produce steel in a basic oxygen furnace. In the secondary route of steel making steel is produced using sponge iron.
