Hot Briquetted Iron (HBI)
Hot Briquetted Iron (HBI) is a high-quality metallic charge material produced by the direct reduction of iron ore using natural gas or coal, followed by immediate briquetting at high temperatures. This process results in a product with a density greater than 5.0 g/cm³, significantly reducing the reactivity associated with Direct Reduced Iron (DRI). Moonarc FZCO supplies HBI characterized by high metallization, consistent chemical properties, and low levels of residual elements, making it the ideal raw material for Electric Arc Furnace (EAF) and Basic Oxygen Furnace (BOF) operations aiming for high-purity steel grades.
Applications
- Electric Arc Furnace (EAF) steelmaking as a high-quality scrap supplement/substitute.
- Basic Oxygen Furnace (BOF) coolant and iron source.
- Blast Furnace (BF) burden enrichment to increase productivity and reduce coke rates.
- Foundry applications for high-purity iron requirements.
Industries served
- Steel Manufacturing
- Foundries
- Metallurgy
- Automotive (Raw Material Supply Chain)
Key benefits
- High density (5.0 g/cm³ min) allows for efficient transport and outdoor storage without the reactivity risks of DRI.
- Low residual elements (Cu, Ni, Cr, Mo, Sn) critical for high-grade steel production.
- Enhanced furnace productivity due to high metallization levels.
- Reduced CO2 footprint in EAF steelmaking compared to integrated routes.
- Predictable chemical composition for precise slag management.
Technical specifications

Storage
Store on a dry, well-drained surface (preferably concrete). Keep away from open flames and strong acids. In bulk storage, monitor internal pile temperatures. Ensure adequate ventilation in enclosed warehouses to prevent gas accumulation.
Handling
Use heavy-duty handling equipment. Minimize drop heights to prevent the generation of fines. While HBI is significantly less reactive than DRI, it should still be kept away from bilge water and acids. Ensure proper ventilation in confined storage spaces to prevent potential hydrogen buildup if wet.
Transport
Classified as 'Direct Reduced Iron (A), Briquettes, hot-molded' under the IMSBC Code. It is significantly more stable than DRI (B). Requires ventilation and moisture protection. Non-restricted for road and rail transport in most jurisdictions.
Packaging options
Bulk Vessel (Handysize to Capesize) · Big Bags (1.0 - 1.5 MT) for foundry use · Containerized Bulk (20ft units)
