Hot Briquetted Iron (HBI)
Hot Briquetted Iron (HBI) is a high-quality version of Direct Reduced Iron (DRI), created by compacting at temperatures above 650°C, resulting in a material with a density exceeding 5,000 kg/m³.HBI is primarily used in electric arc furnace (EAF) steelmaking, but it also serves as a trim coolant in basic oxygen furnace steelmaking and as a feedstock for blast furnaces.In integrated mini-mills, DRI can be hot-charged into the EAF at around 650°C, leading to substantial energy savings.
Pig Iron
Pig iron is obtained by smelting iron ore (or ilmenite) with a high-carbon fuel and reductant like coke, often using limestone as a flux. Charcoal and anthracite can also be used as fuel and reductants.It is available in various ingot sizes and weights, from 3 kg to over 50 kg.Most pig iron is produced and used within integrated steel mill complexes.
