About Sponge Iron

Sponge iron, also known as direct reduced iron (DRI), is a metallic product obtained by reducing iron ore in solid state using reducing gases such as carbon monoxide and hydrogen. It serves as a crucial raw material for the steel industry, offering advantages like lower production costs, higher purity, and reduced environmental impact compared to traditional steelmaking methods.

Sponge iron production using coal-based systems started in India in the early 1970s to substitute steel melting scrap. Orissa Sponge Iron and Steel Ltd. (OSISL) developed a patented coal-based sponge iron technology called the "OSISL Process" in 1988 to overcome the limitations of the earlier ACCAR process. Moreover, India has been the world's largest sponge iron producer since 2003, with 30% of its steel production coming from this route.

Properties of Sponge Iron

Sponge iron typically has a high iron content of 90% or more, low levels of impurities, and a spongy, porous structure, with lump sizes ranging from 3 to 20 mm and a maximum of 5% fines (-3 mm). Chemically, it contains a metallic iron content of at least 81%, a total iron content of 91% minimum, and a metallisation degree of 88% or higher. Additionally, it has low sulfur (0.03% max) and phosphorus (0.07% max) content, with carbon levels typically below 0.15%. These properties make sponge iron an ideal substitute for steel scrap in electric arc furnaces.

Manufacturing Process of Sponge Iron

The production process of sponge iron begins with iron ore preparation, where the ore is crushed and ground into a fine powder. This powder is then mixed with a reducing agent, typically coal or natural gas, along with fluxes like lime. The mixture undergoes pelletisation to form uniform-sized pellets, which are subsequently fed into a rotary kiln. In the kiln, the pellets are heated to temperatures between 1000°C to 1200°C in the presence of reducing gases (CO and H2), leading to the formation of sponge iron as iron oxides are reduced to metallic iron. After the reduction process, the sponge iron is cooled to stabilise the product and is then separated from non-metallic components (gangue) for collection and further processing.

Making of Sponge Iron

The production of sponge iron involves several steps, as outlined below:

1. Preparation of Raw Materials

The primary raw material for sponge iron production is iron ore, which is crushed and screened to remove impurities. The iron ore used is usually in the form of lumps or pellets. Non-coking coal is used as a source of carbon and energy, while limestone is added as a fluxing agent to remove impurities in the form of slag.

2. Reduction Process

The reduction of iron ore takes place in a rotary kiln, where it is heated at a temperature of 800°C to 1050°C in the presence of a reducing gas. The reducing gas is generated from the incomplete combustion of coal. The main chemical reactions involved in the reduction process are as follows:

Chemical Reactions

1.    Formation of Carbon Monoxide (CO):

C + O2 → CO2

CO2 + C → 2CO

2.    Reduction of Iron Ore to Sponge Iron:

Fe2O3 + CO → 2FeO + CO2

FeO + CO → Fe + CO2

Overall Reaction: Fe2O3 + 3CO → 2Fe + 3CO2

3.    Formation of Slag:

CaCO3 → CaO + CO2

CaO + SiO2 → CaSiO3 (slag)

3. Cooling and Separation

After the reduction process, the sponge iron is cooled to room temperature using water or an inert gas like nitrogen. The cooled product is then separated from unreacted coal and impurities using magnetic separation.

4. Final Product

The final product is porous, metallic iron known as sponge iron or Direct Reduced Iron (DRI). It has a high iron content and is used primarily as a feedstock for electric arc furnaces (EAFs) and induction furnaces in steelmaking.

Applications and Drivers of Sponge Iron

The sponge iron market is primarily driven by its applications in the metallurgical and steel industries, where it serves as a key raw material for electric arc furnaces. As a high-purity iron source, sponge iron is favoured for producing high-quality steel, particularly in regions with limited scrap availability. The increasing demand for steel due to infrastructure development and urbanisation also fuels the growth of the sponge iron market. Additionally, technological advancements in production processes and government initiatives to boost domestic steel manufacturing further enhance market opportunities.
