Sponge Iron

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 (2,190 °F)).

The direct reduction process is comparatively energy efficient. Steel made using DRI requires significantly less fuel, in that a traditional blast furnace is not needed. DRI is most commonly made into steel using electric arc furnaces to take advantage of the heat produced by the DRI product.

Sponge Iron Pellets

Sponge Iron Pellets are high-quality, uniform raw materials specially designed for use in Direct Reduced Iron (DRI) production. Made from carefully processed iron ore fines, these pellets provide a clean, consistent, and efficient feed for rotary kilns and gas-based DRI plants.

• Beneficiation: Upgrading of iron ore fines to improve Fe content.
• Pelletization: Formation of green pellets by mixing fines with binders and fluxes.
• Induration: Heat treatment to harden and strengthen the pellets.
• Reduction: Use of these pellets in rotary kilns or shaft furnaces to produce sponge iron.
• Uniform size and chemistry for smooth kiln operation
• Higher metallization and energy efficiency
• Environmentally friendly, utilizing iron ore fines that would otherwise be wasted
• Consistent quality leading to higher productivity in steelmaking.
