tunnel sponge iron kiln process

Production of Sponge Iron through Tunnel Kiln Process

Direct reduced iron(DRI), also called sponge iron, is produced from the direct reduction of ironore (in the form of lumps, pellets, or fines) to ironby a reducing gas Tunnel kiln furnace are evolving as an alternative to Rotary kiln process. Iron ore fines and the low grade beneficiated iron ore cake are directly used for SPONGE IRON PRODUCTION FROM ORE -COAL

Technology for producing sponge iron in tunnel kiln

Direct-reduced iron (DRI) is commonly called as sponge iron in China, and its production method has a variety of, and coal-based tunnel furnace method is one of them.Coal-based tunnel furnace method is well suited for China's national situation, and the process links of this technique is few, and equipment is simple, stable, simultaneously without coke, The reduced iron particles sinter together to form a hollow cylinder of sponge iron that has pores between and within the iron particles. Figure 1 shows the cross section of +40 mesh ground magnetite powder.
