1. Krupp Sponge Iron Process The Krupp. Sponge iron process uses a rotary kiln for the reduction of high grade lump ores or pellets (Fig. 1). The feed is introduced together with reducing and de-sulphurizing agents (lime-stone or raw dolomite) into an inclined rotary kiln, heated counter current to the flow of hot gas and reduced to form sponge iron.

Jan 18, 2014 Fine iron ore is preheated and reduced to fine direct reduced iron (DRI) in a three or four stage fluidized bed reactor system. The fine DRI will be compacted and then charged in the form of hot compacted iron (HCI) into the melter gasifier. The charged HCI is subsequently reduced to metallic iron and melted. The generated FINEX export gas is a highly valuable product and can be further used.

Sponge Iron an overview ScienceDirect Topics

3.3.3.1 Direct Reduced Iron. DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200 °C. Iron oxide is charged into shaft furnace, rotary kiln, or fluidized beds in the form of pellet, iron ore

Direct reduced iron Wikipedia

Direct reduced iron, also called sponge iron, is produced from the direct reduction of iron ore to iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example being heating iron

The reasons for the success of Sponge Iron Industry in

The sponge iron production increased by 20% on a Y-O-Y basis in 2014 as the non-coking coal supplies improved. However, the sponge iron prices increased marginally by ~2% Y-O-Y owing to demand-supply mismatch. The EAF steel production grew 8% in the period as compared to a double digit growth in the production of sponge iron.
