Figure 3.3.19. Thermal energy consumption across sample sponge iron plants. Figure 3.3.20 shows the steel production across different plants. The steel production ranges from 30,000 tons to 0.14 Mt. This may be due to the export of SI and scrap utilization in the Usually the degree of metallization of sponge iron lies in the range 90-97%, and it is the chief factor en- abling us to judge whether it is uitable for us in steel smelting.

From Ore to Iron with Smelting and Direct Iron Reduction
The reduced iron along with coal and lime is fed to a gasifier-melter, which completes the reduction process and produces pig iron or hot metal of the same Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into 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 mDirect reduced iron

Removal of Phosphorous from Steel Produced by Melting
In the present work, dephosphorization experiments have been carried out as discussed in previous section. Total five heats were processed using cast iron, steel Gross calorific value (GCV) of different coals for sample sponge iron plants. Figures 3.3.25–3.3.27 show the comparative performance of four plants. The overall SEC of the sample plants is in the range of 7.58–7.86 Gcal/ton steel. The total electrical SEC up to SI making ranges from 77 to 135 kW h/ton of SI.Sponge Iron an overview ScienceDirect Topics

Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C Direct reduced iron

Steel is made in steel melting shop in the refractory lined vessels called LD Converters by blowing oxygen through the hot metal bath. While iron making is a reduction process, steel making is an oxidation process.Direct reduction iron or sponge iron is an old method for producing hydrogen (Milne et al., 2006; Peña et al., 2010; Biljetina and Tarman, 1981) that was replaced by more efficient and economic processes.Recently, the interest in sponge iron as a hydrogen production process has grown again, although the technology still has some major technical and Sponge Iron an overview ScienceDirect Topics

The use of sponge iron in steel smelting
sponge iron. In the compaction process a partial impoverishment of the ore takes place on account of the solid reducing agent or the bonding additions. An essential condition in the use of sponge iron as a substitute for steel scrap is a maximum content of reduced (metallic) iron and a low gangue content.The company commenced operations in 1998 with a symbiotic relationships with the then Zimbabwe Iron and Steel Company (ZISCO). Our operations two rolling mills to produce light and medium structural steel sections from bloom and billets supplied by ZISCO.

Adityapur, District Saraikela Kharsawan in Jharkhand.The procedure of sponge iron making aims to expel the oxygen from iron ore. It is produced by direct reduction of iron-ore in solid-state either by reducing gas or non-coking coal at 1000-1050 °C. The resulting iron is highly porous in nature and hence the name sponge iron. Sponge iron is richer in iron than pig iron which has a higher contentDRI (Sponge Iron) Metallics IBMD Tata Steel
