Overview. Hot Briquetted Iron (HBI) is a premium form of DRI that has been compacted at a temperature greater than 650° C at time of compaction and has a density greater than 5,000 kilograms per cubic metre (5,000 kg/m 3 ). HBI was developed as a product in order to overcome the problems associated with shipping and handling of DRI - due to ...

Thereby, they have been reduced at 1200 °C and then crushed into fines with the generation of 95% metallic iron powder of 75 µm and the rest oxidised materials. The present research work comprises of development of briquettes made with reduced iron ore-flue dust fines, 5–7% moisture and 0.5% sodium silicate as a binder.
Details
Compatible with injected fuels and oxygen. Predictable mass and heat balances. These unique characteristics of HBI provide other benefits: High density (5.0 g/cm3) allows for rapid penetration of the furnace slag layer. Increased thermal and electrical conductivity for faster melting. Less fines generation during handling, shipping and storage.

The ratio of these components in the briquette charge depends on the type of imported ore fines. At 30% of the dust content in the mass of the briquette, only 1.5% of the cement by mass of the briquette is required. The share of cement increases to 3% at 15% of the content in the dust in the briquette. Fig. 3.82.
