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

Pig iron nuggets were produced in a laboratory scale furnace at. Michigan T echnological University. These nuggets are produced from. pellets consisting of a mixture of iron oxide, coal, flux, and ...

The production of sponge iron begins with the direct reduction of iron ore. In traditional iron-making processes like the blast furnace, iron ore is smelted to obtain pig iron, which is high in carbon content. However, in the case of sponge iron, the direct reduction process eliminates the carbon content, resulting in metallic iron.

Overview. Pig iron is produced as a co-product through the smelting of ilmenite in electric arc furnaces. The primary product in the process is titanium dioxide slag. Various grades of pig iron are produced at our operations in South Africa. Depending on the grade, our pig iron is sold into the foundry and steel industries.
