Description of HBI:
Hot Briquetted Iron (HBI) is a premi-um, high density steel industry rawmaterial containing 90-94% totaliron (Fe) in a nearly pure form, whichis used in electric arc furnace (EAF)and basic oxygen furnace (BOF)steelmaking and blast furnace (BF)ironmaking applications.

Definition of HBI Listed in IMO* as:Direct Reduced Iron (A) Briquettes,hot-moulded* Code of Safe Practice For Solid Bulk Cargos (BC Code), 1994Edition, International Maritime Organization (IMO), London, 1994.
HBI is a compacted form of Direct ReducedIron (DRI), a metallic material manufac-tured by processes that reduce (i.e.,remove oxygen from) iron oxide fines, lump,and pellets at temperatures below the melt-ing point of iron.
IMO defines HBI as: “A material emanatingfrom a densification process whereby thedirect reduced iron (DRI) feed material is ata temperature greater than 650°C at timeof moulding and has a density greater than5.0 g/cm3. Fines (under 4mm) not toexceed 5%.”
