Effect of reduction conditions on structure and phase

01-02-1999· The effect of pellet content on the reducibility (dR/dt O/Fe=0.9) of the blast furnace charge composed of sinters and pellets was observed. The reducibility of a blend composed of 40% sinter and 60% pellets is comparable to that of self-fluxing sinter (CaO/SiO 2 =1.1).

Reduction of Iron Ore Pellets, Sinter, and Lump Ore

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 layered structure. The iron‐bearing materials consist of iron ore pellets, lump ore, and sinter. When the charge material descends, it is reduced by CO and H 2.

Blast Furnace Operation an overview ScienceDirect Topics

Internally the blast furnace is considered to consist of five discrete zones, see Fig. 17.2, through which all furnace gases and/or liquids must pass.The location, shape and extent of each zone is influenced by the properties of the material layers (relative thickness, etc.) and by the properties of the materials themselves. These factors interact to determine the flow and distribution of
