The total reaction involved in the process of sintering is the sum of a number of reactions which involve reactions in heating zone, reactions in sintering zone and reactions in cooling zone. These reactions are illustrated schematically for typical sintering of a lime-fluxed haematite ore in Fig. 11. Fig. 11.1 Development of Minerals during.
Granule growth is an important process for iron ore sintering process. Variation of granule size has a great influence on the quality of sinter and productivity of the process. In this study, a model of granule growth was proposed based on two dimensional homogeneous sphere packing theory. The sintering.
Sep 01, 2016 In iron ore sintering process, as shown in Fig. 1, raw materials including iron ores, fluxes, return fines and fuel are blended and mixed first. The blended mix is further granulated in drum with the addition of water to get a coarser particle size and narrower size distribution.
Modeling and simulation of processes from an iron ore sintering plant. Share on. Authors Corina Maria Dinis. Department of Electrotechnical Engineering and Industrial Informatics, Politechnica University Timisoara, Hunedoara, Romania.
The iron ore sintering process prepares fine iron the ores for the blast furnace process. Sinter plants agglomerate iron ore fines with other fine materials at high temperature in a mix bed to create a product that can be used in a blast furnace. Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux.
Iron ore sintering involves the movement of a flame front down a particulate bed, and a series of phys- ico-chemical reactions over a large temperature range. In the literature simple and sophisticated iron ore sintering models have been reported. In this paper a comprehensive numerical model.
We aim to publish a Special Issue of the journal Minerals that presents a set of themed articles on the “Evolution and Modeling of Iron Ore Sintering Process”. The main focus will be on the actual status and developments of the iron ore sintering process and discussing new insights into ongoing technologies with potential for integration and sustainable approaches, from raw material selection and preparation to technological predictions of sinter.
Utilization in iron-ore sintering process. The course and a thermal e ect of individual reactions that take place during combustion of carbonaceous fuels (coke breeze or charcoal) in the agglomeration process were modeled using thermodynamic program HSC Chem-istry 5.11. In.
In the iron ore sintering process, air flow rate is a major factor in determining the flame front speed which in turn influences the sinter quality and productivity. In the present work, sintering characteristics of an Asia Pacific blend of Australian and Brazilian iron ores were extensively studied in an experimental sinter pot test system to determine this parameter for two limiting cases.
Dec 13, 2016 A mathematical model was developed for the iron ore sintering process considering all the major thermochemical phenomena in the system, assuming both the static and moving bed configurations. The model predicted a large number of parameters pertinent to the sintering process including the temperatures of the gas and solid, concentration of.
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.

In this paper a new technology for a compact iron ore sintering machine is analyzed. The compact sintering process is based on the massive injection of gaseous fuels and the solid fuel is only agglomerated fine charcoal obtained by biomass. The solid fuel used in this study is obtained by agglomeration of fine charcoal produced from elephant glass which has very short period for.
Iron ore sintering Part 1 Theory and practice of the Technical Report UDC 622 785 5 548 73. 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 The process of iron ore sintering is a non equilibrium process that takes place within a very short time and.
Jan 21, 2016 Optimization of iron ore sintering process is to maximize the productivity and the sinter ore quality while minimizing the energy consumption. However, these economic and technical criteria are sometimes contradictory and the improvement of one criterion generally leads to the deterioration of other criteria. This paper aims to seek the optimal manipulated parameters from the production data.
