In several studies on injection of fluxes and iron ore, the effect on hot metal composition has been considered. Tuyere-injection of flue dust into the blast furnace might have similar effects as those foundin these studies. Injections of fines of fluxes and iron oxide in some blast furnaces to decrease the Si content of hot metal have been
Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64%-72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...

The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization:
The objective of this research is to assess how much the improvement in the combustion reaction efficiency can reduce fuel consumption, maintaining the same thermal energy rate provided by the reaction in a pelletizing furnace. The furnace for pelletizing iron ore is a complex thermal machine, in terms of energy balance.
EFFECT OF SIZE DISTRIBUTION AND WATER CONTENT ON PROPERTIES OF IRON ORE PELLETS ... of properties of the chief raw materials of pelletization: iron ore fines and water ... pelletization of iron ore has been found to markedly increase the efficiency of the blast furnace operation. This is due to the spherical shape and close
pressures. Pelletization of fine powders has grown enormously in importance as an industrial process and particularly so in the iron ore industry. Besides such inherent advantages as densification and prevention of dust losses, the pelletization of iron ore has been found to markedly increase the efficiency of the blast furnace operation.
Pelletization (Agglomeration of ores) In iron ore pelletization, bentonite is commonly used as an agglomeration aid to augment pellet growth and add physical strength to the pellets. While bentonite is effective as a binder it has a contaminating effect on the chemical quality of the pellets, adding both silica and aluminum gangue.
Effects of Iron Ore Elements on Steel Making. ... Some chemicals are deliberately added such as flux which makes a blast furnace more efficient. Others are added because they make the iron more fluid, harder, or give it some other desirable quality. The choice of ore, fuel, and flux determine how the slag behaves and the operational ...
Iron ore pellets are largely characterized by inherent physical and chemical properties of ore as well as pelletizing conditions including induration time, induration temperature, etc. These parameters essentially vary with types of ores. The production of high-quality pellets from hematite ore is challenging because of high level of fineness (Blaine number) and induration temperature ...
In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1200 °C). The direct reduction process is comparatively energy efficient.
