While sintering is suitable for iron ore fines in the size range 0.15–10 mm, pelletization is suitable for even finer iron ore. During sintering, iron ore fines, iron-bearing steel plant wastes, and recycled undersize sinter melt partially in the presence of fluxes and fuse together upon cooling to form a hard porous agglomerate called ...
The sinter plant that converts the iron ore fines into a desirable blast furnace feed, offers an avenue for recycling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet fines, which cannot be directly used in iron making. The present study evaluated the influence of these pellet fines on …
Iron ore fines, coke breeze, limestone and dolomite along with recycled metallurgical wastes are converted into agglomerated mass at the Sinter Plant, which forms 70-80% …
Abstract The sinter plant that converts the iron ore nes into a desirable blast furnace feed, oers an avenue for recy - cling wastes. One of the several wastes that are produced at an iron and steel plant is the undersized pellet nes, which cannot be directly used in iron making. The present study
FeO so formed combines with SiO 2 and fluxes resulting in the formation of fluxed sinter.. The flexibility of the sintering process permits conversion of a variety of materials, including iron ore fines, captured dusts, ore concentrates, and other iron-bearing materials of small particle size (e.g., mill scale) into a clinker-like agglomerate.
The sintering process begins with preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel (called bonding agents in Japan) such as coke …

Recently, the sinter plant at Tata Steel's Kalinganagar works has faced issues of high internal return fines generation. As the sinter plant begins to increase its productivity levels, it becomes critical to control the generation of internal return fines to allow fresh material consumption.
For pelletization study, as received iron oxide pellet fines were ground to below 150 μ using ball mill. The particle size distribution of ground iron ore fines was determined by the Malvern particle size analyzer (Hydro 2000MU, UK) and shown in Fig. 2.Blaine number was measured to determine surface area of the iron oxide pellet fines …
Abstract. Large amounts of iron ore sinter are produced throughout the world. The development of sustainable and energy-efficient technologies has become …
Iron ore and iron ore pellets are important sources of iron for manufacturing steel. The iron ore production has significantly expanded in recent years, owing to increasing steel demands in
raw materials (like coarse as well as fine iron ores, ultra-fine ores/pellet feed, additives, dusts, solid fuels, return fines, and recycled materials from the steel plant) are continuously fed into a high-speed intensive mixer where macro- and micro-mixing of the sinter raw mix takes place.
Prior to dispatch of sinter to the blast furnace for hot metal production, the sinter product from the sinter cooler is screened to remove smaller/finer particles. The undersize so generated is called internal return fines, which are generally recirculated into the sintering machine. A very high level of internal return fines generation limits the use …
The sintering process begins with the preparation of a sinter mixture consisting of iron ore fines, fluxes, solid fuel (called bonding agents in Japan) such as coke breeze, and return fines from the sinter plant and blast furnace as well as recycled ferruginous materials from downstream iron and steelmaking processes.
The ingredients – iron ore, coke and limestone fines – are carefully stacked and blended, then passed under an ignition hood at the sinter plant. This heating process is carefully controlled to make sure the resulting sinter has the right composition and optimum sizes for the next stage of the process at the blast furnaces.
The steel plant fines were mostly dumped as waste in the past. The dumping of waste fines is not acceptable at present. ... Sintering of Iron Ore Fines Sintering is an agglomeration-technique for enlarging the iron ore particle size. The use of iron ore sinter in a modern day blast furnace has become common due to various advantages …
Iron ore sinter plants are energy-intensive components of integrated iron and steel production (see Table 1), where the iron ore fines (<5 mm) are converted into larger (>5 mm) lump sinter cakes with greater gas permeability, which are the most important burden materials for iron making in blast furnaces (BFs) [7].The main process is shown …
Sinter is the primary feed material for making iron in a blast furnace. According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. ...
In iron making process, sintering of iron ore fines is an integral step to utilize not only the ore fines but also to introduce a part of flux (limestone and dolomite) along with the sinter in blast furnace burden. In this way, the productivity of the furnace...
