Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore.

Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Due to the depleting reserves of traditional high-grade iron ore, there have been considerable changes in iron ore resources available throughout the world, especially in steel mills in East Asia. Corresponding to the changes in the availability of iron ore resources, the.

Some Sinter Feed cargoes are produced by a concentration process, and are therefore a sub -type of Iron Ore Concentrate (itself a Group A cargo listed in the Code), whereas others are unprocessed fines. As such it is a cargo which effectively has the same characteristics as Iron Ore Fines and is subject to the same risksof liquefaction.

Recently, the quality of sinter feed ore used in sintering process has deteriorated. In particular, Fe has decreased and gangue component has increased in the sinter feed ore. Increase of gangue is not only the factor to influence sinter qualities, but also the factor to increase coke ratio in the blast furnace operation as the increase of slag ratio.

Jan 19, 2015 This paper explores NOx emission during iron ore sintering on a pilot-scale pot. A novel technique of using a three-layered bed structure was adopted to study the role of coke level, properties and combustion behavior on NOx emission. In addition, the lime content of the mix was also altered to understand the effect of the melt formation process. Thirteen sinter pot tests were employed to.

The NaAlO2 compound in the sinter is leached by water and Al(OH)3 is further precipitated from the solution by CO2. The process residue contains iron and aluminum and there will be loss of these elements. over, the bauxite ore contains usually some SiO2, and in the sintering step Na2SiO3 is formed, which is unwanted. In practice,.

During the iron ore sintering process, two types of particles are present in the sinter bed (1) fines, which are actively taking part in melting and the formation of secondary phases, and (2) coarse ores, which are partially interacting with the surrounding melt. The quality of the final sinter is particularly determined by the secondary phases and their bonding ability.
