High-Purity Sponge Iron for EAF & Induction Furnace Steelmaking
Samanar supplies high-quality Sponge Iron (DRI) with consistent chemistry, high metallization, and low impurities — ideal for EAF, IF, and integrated steel plants.
Sponge Iron
About Product
Sponge Iron — also known as Direct Reduced Iron (DRI) — is produced through the direct reduction of iron ore using reducing gases such as natural gas or syngas. Unlike blast furnace pig iron, sponge iron is a solid-state product with exceptionally high metallization, making it an essential raw material for Electric Arc Furnace (EAF) and Induction Furnace (IF) steelmaking.
Samanar provides sponge iron with globally competitive quality that ensures high melting efficiency, low energy consumption, and stable furnace performance. With controlled Fe content, low sulfur and phosphorus levels, and consistent physical properties, our DRI enhances productivity in steel mills while minimizing impurities and operational costs.
Our material is sourced from certified direct reduction plants with advanced reformer technology, quality monitoring systems, and continuous process control loops, ensuring stable chemical and metallurgical characteristics in every shipment.
How Sponge Iron Is Produced
Sponge Iron is manufactured using the DRI Process, which includes:
Iron Ore Preparation
Iron ore fines are beneficiated and pelletized (6–16 mm)
Required Fe content: 64–69% depending on plant requirement
Reduction in the Rotary Kiln or Shaft Furnace
Natural Gas → Reformed Into CO + H₂ (reducing gases)
Reduction of oxides (hematite/magnetite → metallic Fe)
Solid-state reduction without melting point
Cooling and Discharge
Material discharged at ~100–200°C
Cooled and stabilized for transport
Screening, Sizing & Metallization Control
Metallization levels typically 85–92%
Screening into 3–18 mm (common DRI size)
Final DRI is porous, reactive, and ideal for melting in EAF/IF furnaces.

Frequently Asked Questions
Metallization above 90% gives the best melting efficiency and low energy usage.
Yes — depending on furnace design, DRI can replace up to 100% of scrap.
DRI is highly reactive; therefore proper packaging and handling are essential. Samanar only supplies stabilized and export-ready DRI.
If needed, we can supply HBI as well.
Every bundle is accompanied by an MTC certificate, traceable heat number, and passes factory inspection. Optional third-party inspection can be arranged for major projects.
