Sponge iron is also known as direct reduced iron (DRI).
The making of sponge iron is a process in which iron ore lumps (usually 5 to 18 mm in size) and sponge iron are used in the iron and steel industries as a substitute for scrap in induction furnaces and electric arcs.
And sponge quality with excellent metal content and flawless consistency in terms of chemical and physical properties.

And further, explain sponge iron, Direct reduction is an alternative way of making iron that has been developed to overcome some of the problems of conventional blast furnaces.
And DRI is successfully produced through gas or coal technology.
Direct Reduction Iron Process
Producing of sponge iron is a procedure in which iron ore pieces (normally 5 to 18mm in size) of the selected grade of small dolomite ferrous coking coal are poured into a sloping rotary kiln and ignited in the presence of air for about 12 hours.
Before the products are cooled by air, they are magnetically separated, screened, and inspected in the warehouses of the final product before shipment.
The process requires the direct reduction of iron ore ( the removal of oxygen from the ore) in the solid state to the ore at a critical temperature of the metal to allow this.
In more explanation DR process can be broadly classified into two groups: the first one is Using solid reductant, that is coal-based DR process and the second one is using gaseous that is gas-based DR process, coal-based processes non-coking and advantages of coal based process are they do not need the high-coal grade, which is rarely available and they use non-coking coal and they can be installed with less capacity and coal is sued as In coal-based DR processes, non-crumbly coal is used Reducing agent.
In solid reduction processes, iron oxides, and modified natural gas is used as a reducing agent.
Iron ore Masses or pellets decrease in solid and oxygen state It is removed from iron oxide by a gaseous reducing agent.
Processes are based on gas It is now very standardized.
Gas is a clean source of fuel and there is no problem with ash content, as in the case of coal, which leads to the formation of the ring and other attendant problems.
Sponge Iron vs Pig Iron
Sponge iron is a form of iron that can be produced directly from iron ore through the reduction process, while pig iron is a type of iron that can be produced by melting iron ore with coal and limestone under very high pressure.
In addition, another difference between sponge iron and pig iron is that sponge iron is porous while pig iron is not porous and, therefore, is relatively denser.
Apart from that, there is a difference between sponge iron and cast iron in their production process.
In the sense that, the process of producing sponge iron is a liquid state process while a solid-state process is for pig iron.
Summery, both sponge iron and crude iron are the two main forms of iron that can be obtained by processing natural iron ore.
The main difference between sponge iron and crude cast iron is that we can produce sponge iron by directly reducing iron ore through reducing agents while producing crude iron by melting iron ore with coal and limestone at very high pressures
What Is Sponge Iron Used For
Sponge iron basically created in the iron and steel industry as a substitute for initiation furnaces and electric arcs.
Over the years, the shortage of expensive smelters has turned sponge iron into a significant raw material to produce high-quality steel.
DRI is growing rapidly worldwide Since the 1980s, it has been mainly due to a lack of coke Coal for BF and scrap steel in steelmaking.
DRI is produced by DR iron ore using non-coke coal, Natural gas.
The bulk of DRI production is used as an Alternative to scrap are used in DRI steelmaking Three forms of the primary product, namely mass, pellets, and Hot briquettes.
About 5% of the world’s steel is produced from sponge iron (DRI) and this trend is increasing.
This product is obtained from the direct reduction of iron ore and is also called DRI.
Today, sponge iron is made by reducing iron ore without melting it.
This makes it an efficient energy source for certain steelmakers who rely on scrap metal.
Sponge Iron Price
The global sponge iron market research report (2022-2028) focuses on the global state of sponge iron, forecasts, growth opportunities, major markets, and key players.
The report also includes detailed data on the main factors affecting the growth of the sponge iron market at the national and local levels, as well as forecasting market size in terms of value, market share by region and sector, and regional market position.
Sector and country growth opportunities.
And following the recent jump in iron ore and coal prices, the two key inputs of these products, the prices of steel production intermediaries such as sponge iron and crude cast iron have fluctuated sharply.
India With a production of more than 53 million tons (MT), India is currently the fifth largest steel producer in the world.
Steel production grew at a combined rate of 9% from FY 03 to FY 08.
And according to trade sources, the price of sponge iron has increased by 25% since November.
