Pellet (steel industry) Iron ore pellets produced by LKAB, from ore mined in northern Sweden. Pellets are a processed form of iron ore utilized in the steel industry, specifically designed for direct application in blast furnaces or direct reduction plants. These pellets are spherical in shape, with diameters ranging from 8 to 18 millimeters.

2020130· 1. Introduction A blast furnace (BF) is the most common process for hot metal production in the world. The BF is charged with metallurgical coke and iron-bearing materials separately, which leads to a lay-ered structure. The iron-bearing materials consist of iron ore pel-lets, lump ore, and sinter. When the charge material descends, it is reduced by CO and H2. In …
