Hot Briquetted Iron (HBI) is the densified briquette form of Direct Reduced Iron (DRI). DRI is discharged hot from the reduction furnace and screwfed into the nip between - two counter rotating rollers. Pockets in the synchronously rotating rollers form the briquettes. This process occurs at high temperatures (at least 650°C [1202°F]) and high
In this research, using iron-oxide fines (average size: 2.5 μm) and biochar fines (average size: 50.0 μm), the biochar composite briquette (BCB) for blast furnace (BF) application was prepared by cold briquetting followed by heat treatment. The preparing conditions were optimized regarding its cold crushing strength. Anti-pulverization capability, reaction …

The crushing strength of the briquettes after firing were all over 200 kgf with a maximum value of 367 kgf obtained at a basicity of 1.22 . The crushing strength after reduction showed a strong response to changes in the basicity level, increasing from 22 kgf at a basicity of 0.33 to 121 kgf at 1.97 . This change in strength is considered to be ...
