Iron ore pellet properties under simulated blast furnace . - Jultika

Jun 9, 2017 . Abstract. A blast furnace is the dominant process for making iron in the world. Iron ore pellets are commonly used as iron burden materials in a blast furnace, in which iron oxides are reduced to metallic molten iron. While descending, the charge faces various stresses, which affect the gas flows in the shaft.
