The commercial process is a solid solution reduction, also called Direct-Reduced Iron (DRI). It is a different route of iron making that has been started to stop some of these problems shown by conventional blast furnaces. DRI is successfully made through coal-based systems. Our Group is the market leader in the manufacture of DRI in Eastern India.

Kiln is defined as equipment where no phase change reaction of the raw material undergoing heat treatment takes place (e.g. a reduction process). Waste heat. Waste heat is by-product heat of the furnace/kiln operation. Production output. Production output refers to the total output from the production process including rejects. Reject.
We look at the 4 different methods of producing sponge iron: Midrex process HYL process (4th generation) or Energiron SL / RN process Tunnel furnace process 1) Midrex process Miderx's involvement in the direct reduction process can be traced back to the work done by Surface Combustion Company in the 1930s.
The material discharged from the kiln consists of a mixture of sponge iron, surplus fuel, desulphurizing agent and ash, and is cooled down in a rotary cooler, mainly by direct spraying with water. Further treatment of the mixture consists of a combination of screening, magnetic and gravity separation.

lance with high-pressure nitrogen. The process duration varies with the injection rate, hot metal chemistry, and desired final sulfur content, and is in the range of 5 to 30 minutes. 12.5.1.4 Steelmaking Process — Basic Oxygen Furnaces - In the basic oxygen process (BOP), molten iron from a blast furnace and iron scrap are refined
The first gas based sponge iron plant, with a capacity of 1.52 MTPA, was set up by Essar Steel Limited in Hazira, Gujarat in 19905. Today, India has an installed capacity of 36.7 MTPA of sponge iron6. Leading states in sponge iron production are Odisha, Chhattisgarh, West Bengal and Jharkhand. Odisha occupies the top position
The process of sponge iron making aims to remove the oxygen from iron ore and when the same occurs, the departing oxygen causes micropores in the ore body making it porous. . The final product when observed under a microscope, resembles a honeycomb structure looking "spongy" in texture and hence the name sponge iron.

Iron oxide ores extracted from the Earth are allowed to absorb carbon by a reduction process. In this natural reduction reaction, as the iron ore is heated with carbon, it results in a pop-marked surface, hence the name "sponge iron." The commercial process is a solid solution reduction, also called direct-reduced iron (DRI). In this process, the iron ore lumps, pellets, or fines are heated …

The process of making sponge iron occurs by removing oxygen from the iron ore. The quality of sponge iron is mainly determined by the percentage of metallization (removal of oxygen). This parameter is equal to the ratio of metal iron to total iron in the product. Sponge iron itself is not used but can be processed to produce molten iron. The dangers of sponge iron include …
