With such dimension of notion We in our Sponge Iron Manufacturing process through 4 Kilns (2 * 50T and 2 * 40T) laid up the best DRI making process of India. It is Coal Fuel based DRI. Coal based Sponge-iron is a metallic product produced through direct reduction of iron ore in the solid state .As such it is also known as Direct Reduced Iron (DRI).
The HYBRIT process involves removing the oxygen from the iron ore using hydrogen. The reduction occurs at a lower temperature and the result is so-called sponge iron (direct reduced iron). The sponge iron is smelted in a furnace, powered by electricity. The furnace is called an Electric Arc Furnace (EAF).

Sponge iron means porous iron produced by direct reduction process.Direct reduction (DR) process is a solid-state reaction process (i.e. solid–solid or solid–gas reaction) by which removable oxygen is removed from the iron ore, using coal or reformed natural gas as reductants, below the melting and fusion point of the lump ore or agglomerates of fine ore [].
The sponge iron process. The longest established of these processes is the sponge iron process, the leading example of a family of processes involving solid state reduction of an oxide. In the process, selected magnetite (Fe3O4) ore is mixed with coke and lime and placed in a silicon carbide retort.
The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten …

Sponge iron is one of the best materials that could be used for coolant in L.D. converters of integrated steel plants. Also read: Iron rod prices and uses. Sponge iron production process DRI unit. In the DRI plant, sponge iron is produced by using the solid reductant iron ore with carbonate materials such as coil.
5. The substitution of scrap by sponge iron has some limitations depending on the furnace operating conditions. Only 20% to 30% of sponge iron can be used in the furnace charge when feeding is done in batches. The proportion of sponge iron in the charge can however be increased to 40-50% by providing continuous feeding arrangements. A

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.
The Sponge Iron Process (SIR) is a well-known technology for the production and purification of hydrogen. It consists of a cyclic process in which a feed gas, rich in carbon monoxide and hydrogen (e.g. syngas), is passed on an iron oxide (magnetite Fe3O4) at high temperature. Magnetite is reduced to wuestite (FeO) or iron while carbon monoxide ...

Sponge iron is a highly ferrous ore from the direct reduced iron process! In order to prevent excessive re-oxidation of the sponge iron in the ambient air, it must be cooled down in the lower region of the shaft furnace.
Sponge iron is produced by low-temperature reduction of iron ore in a rotary furnace, shaft furnace, or reactor. Since the reduction temperature is lower than the melting temperature of the ore, the iron ore still maintains the shape of the ore after solid-state reduction, and has a porous and low-density sponge-like structure, hence the name ...
