The process of iron ore sintering is a nonequilibrium process that takes place within a very short time, and to clarify its process mechanisms, an analytical approach combining a phase diagram of a multicomponent system and insitu observation of hightemperature reactions is effective. However, insitu observation of hightemperature reactions accompanying the .
Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics. Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast .

The use of charcoal for sintering appliions has been evaluated in separate experiments in the world. These experiments indie that charcoal can replace a portion of the coke breeze (approximately 2030%). The aim of this thermodynamic study was to evaluate the possibilities of charcoal utilization in ironore sintering process.
SINTERING PROCESS 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 become the widely accepted and preferred Blast Furnace .

sintering process and more calcium ferrite phases appeared [11]. Earlier studies reported on the properties of iron ore and the quality of sinter. However, there is no unified understanding of the effect of SiO. 2. on the fluidity of iron ore, and the main primary mechanism is not clear. The effect of fluidity of iron ore on the reduction of sinter still lacks deep theoretical insights ...
· Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slagforming 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. The process has .
sive iron ore concentrate, and can use fuels that significantly reduce potentially harmful greenhouse gas emissions. The novel, highintensity flash ironmaking process is a viable alternative that uses plentiful iron ore concentrates. The process would use inexpensive, abundant natural gas, or hydrogen, to produce hot reducing gas which burns at temperatures .
· Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). It''s a major ingredient in steel.

the computational and experimental results of the iron ore sintering process is proposed. Experiments and numerical test cases are designed to simulate sintering pot tests and fuel contents and air supply are parametrically studied. Some quantitative parameters of bed combustion are introduced and the test results are dis cussed in conjunction with these .

iron and steelmaking processes. The sintering of iron ore is an essential stage in the socalled integrated steelmaking process and its main purpose is to prepare fine ores for use in the blast furnace. The sintering process is operated under tight control and it is therefore not possible to examine the influence of wide changes in raw mix composition on production plants. However, .
Elimination of raw limestone from the blastfurnaee burden is known to bring a considerable saving in coke rate. In a country like India or elsewhere, the capacity of the sintering plants is limited it is imperative to produce super fluxed sinter and use it in the furnace. The basicity requirement coupled with the higher gangue input through coke and iron ore demands for a greater .
