Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals.
Sep 30, 2012· Compared with sintered ore, pellets have a higher iron- and a lower gang-content, and pelletizing is suitable for treating the very fine ore that will predominate in the future.
The process of sintering is basically a pre-treatment process step during iron making to produce charge material called sinter for the blast furnace from iron ore fines and also from metallurgical wastes (collected dusts, sludge and mill scale etc.).
Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe2O3) or Magnetite (Fe3O4) and the iron content ranges from 50% to 70%.
Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide to elemental iron mixed with carbon.
The sintering process of iron ore fines sintering plants are normally associated with the production of hot metal in blast furnaces in integrated steel pants.

FUTURE OF SINTERING • The future of sintering and pelletising is directly related to the future of the iron making processes that use sinter and pellets, mainly the Blast furnace and DR process.
Iron ore pelletizing. Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace …
The purpose of the sinter plant is to process fine grained raw materials into a coarse grained iron ore sinter, ready to be charged to the blast furnace. Sintering of fine particles into a porous clinker – sinter – is necessary to improve the permeability of the burden, making reduction easier.
Sinter Quality and Process of Sintering Iron Ores ... Sinter is normally the major component of the blast furnace (BF) charge burden. ... The size of iron ore affects the sintering properties.
Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.
Modeling Sintering Process of Iron Ore 25 Fig. 2. Thermal cycle of the materials in the sinter strand. Several attempts have been done to predict the final properties of the sinter product (Water et al. 1989, Kasai et al. 1989, 1991). The most important parameters are reducibility,
Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2O 3) or Magnetite (Fe 3O 4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into
Electric Smelting Furnace of Ore - 911 Metallurgist. Charcoal blast-furnaces were used for many years to reduce the iron ore, but since 1910 the metallurgists have persevered with the electric furnace, according to Christiansen.
number of its blast furnaces, and as a result, the company produces pig iron mostly on large blast furnaces at high productivity coeffi-cients. What is more, owing to the increase in the injection amount of pulverized coal, the ore/coke ratio of furnace burden has increased, resulting in a relative decrease in the charging amount of coke, which

The degradation of sinter in the blast furnace occurs during reduction in the low temperature zone, and has a harmful effect on the burden strength in the furnace, with the consequent loss ...
Sinter making is a method of fusing iron ore fines into larger particles suitable for charging into the blast furnace. Predominant source of iron in many blast furnace processes. This technology was developed for the treatment of the waste fines in the early 20th century. Since then sinter has
Sintering of Iron Ore Overview An important process in the production of steel from iron ore is iron ore sintering. The sinter is used as feed material for the blast furnace. Iron ore fines, however, are not suitable feed material because they decrease the permeability of reducing gases within the furnace, resulting in low furnace

Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.
Basically, the blast furnace is a countercurrent heat and oxygen exchanger in which rising combustion gas loses most of its heat on the way up, leaving the furnace at a temperature of about 200° C (390° F), while descending iron oxides are wholly converted to metallic iron.
blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process. Pelletizing A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4" and 1/2").
