Rotary Hearth Furnace Iron Direct Reduced Iron

The integrated steelmaking process featuring the blast furnace basic oxygen furnace (BF BOF) where iron ore is the major source of iron units and electric steelmaking based on the electric arc furnace (EAF) where steel scrap or direct reduced iron (DRI) are the major iron feedstock materials Figure 1 major steelmaking process routes.DirectReduced Iron an overview ScienceDirect Topics Direct reduction DR is defined as any process in which metallic iron is produced by the reduction of iron ore at temperatures below the iron melting point The product of a DR process is called direct reduced iron DRI The major consumers of DRI are the smaller steel mills which use DRI to dilute the residual elements present in the steel scrap.DRI DIRECT REDUCED IRON Refractory Iron solutions It is used increasingly in electric furnace steel making DRI competes with higher grades of scrap in steel making and thus enables the use of lower quality scrap In a direct reduction process iron oxide pellets and or lump iron ore are reduced by a reducing gas.A rotary hearth furnace is mainly used in direct reduced iron indistry iron ore powder is reduced and molten into pig iron in the condition of reducing atmosphere Its working temperature is up to 1520 ℃ A rotary heath furnace.
