Abstract: This paper deals with the numerical simulation of the new technology of gaseous fuel utilization on the sintering process of iron ore.
Sinter is the primary feed material for making iron in a blast furnace. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200°C in a continuous belt-fed furnace.

Waste gases from iron ore fine preparations for blast furnace ironmaking, or sintering, contain minute quantities of acidic species, dust, and dioxin pollutants, but because of the very large quantities of iron ore processed and the large volume throughput of air involved, sintering is a major source of these emissions and also CO 2 into the ...
Sintering is a technology for agglomeration of iron ore fines into useful blast furnace burden material. In sintering, a shallow bed of fine particles is agglomerated by heat exchange and partial fusion of the mixed mass. Heat is generated by combustion of solid fuel and mixed with the bed of fines being agglomerated. The
Iron Ore is the most important raw material needed to produce steel. However, it cannot be used directly in the blast furnace. That is why sinter is created that helps converting iron into steel. Rashmi Metaliks has its own Sinter Plant set up at 2007 to have a complete control over the quality of materials used in the steel production process.
Regions in which iron ore has formed over millions of years (e.g. through volcanism) and can be mined economically are also referred to as iron ore deposits. Especially many ore deposits can be found in countries such as China, Australia, Brazil, India and Russia. These countries account for around 85 % of the total global iron ore mining volume.
The iron blast furnace is the most widely used and efficient producer of liquid iron; however, emissions from sintering and coking cause environmental pressure for the integrated steel works. The combustion of coke fines (breeze) during sintering contributes to greenhouse gases (e.g. carbon dioxide) and is a source of SO x and NO x emissions.
Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be ...
With an ore body 4km long, 80m thick and reaching a depth of 2km, LKAB's Kiruna is the world's largest, most modern underground iron ore mine. Since mining began at the site over 100 years ago, Luossavaara-Kiirunavaara AB (LKAB) has produced over 950Mt of ore, yet only one-third of the original ore body has been extracted.
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.

Apr 02, 2020· Iron ore sintering is a type of powder metallurgy used to pre-treat iron before using it in manufacturing applications. Sintering involves heating iron powder to partially, but not completely, melt the iron particles. The exact process used and additional elements involved vary, with some methods using gas or electricity in addition to heat.

Oct 19, 2016· The sintering technology is basically an agglomeration process for the iron ore fines which is dependent on heat to melt the surface of the smaller particles together to form larger agglomerates. A typical sinter plant consists of a number of sequential operating units with the sinter machine at the heart of the plant.
During the iron ore sintering process, the loose raw materials, mixtures of fine ore, limestone flux and coke breeze, are converted into a porous but physically strong cake, which is generally composed of four main phases: iron oxides, ferrites, most of which are a complex silico-ferrite of calcium and aluminum (SFCA), glasses and dicalcium silicate.
