Mineralogical quantification of iron ore sinter
Mineral Processing and Extractive Metallurgy, 2016The mineralogy and microstructure of sinter play an important role in determining the physical and metallurgical properties of iron ore sinter. Characterisation of sinter phases is, therefore, a cost-effective and complementary tool to conventional physical and metallurgical testing of iron ore sinter in evaluating and predicting sinter quality.

Melting temperatures of iron-ore sinter
Steel in Translation, 2015Prediction of the melting temperatures of pure metals, their oxides, and complex iron-ore sinter is considered. A simple formula for the energy state of solids is obtained. Other microstructural factors may be represented in the additive form of the Hall–Petch law.

The porosity of iron ore sinter
2020Iron ore sinter is the main iron-bearing charge in many blast furnaces for ironmaking. A certain porosity of the charge is required to allow the flow of the carbon monoxide-rich reduction gas. The porosity of an accumulation of porous particles is of two types: the interparticle porosity resulting from the voids in the bulk and the intraparticle ...

Rigidity of iron ore sinter mixes
Mineral Processing and Extractive Metallurgy, 2002Productivity during iron ore sintering is a strong function of the gas flow velocity because the descent of the flame front, for a particular ore mix, is primarily dependent on the rate of convective heat transfer.1 Gas velocity is controlled by the suction applied across the bed and the bed properties.

Application of Biomass Pellets for Iron Ore Sintering
Materials Science Forum, 2021The use of biomass as fuel might solve several technological and environmental issues and overcome certain challenges of sinter production. In particular, as revealed by comprehensive analyses, biomass can be used as fuel for iron ore sintering.

Recent advances in iron ore sintering
Mineral Processing and Extractive Metallurgy, 2016Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Owing 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.

Mechanism of sintering and fracture of superfluxed iron-ore sinters
Russian Metallurgy (Metally), 2007Mineral formation in the binders of a commercial sinter with a basicity of 1.6 at the Magnitogorsk Metallurgical Integrated Works has been found to be determined by the crystallization of two morphological forms of high-iron aluminosilicoferrite (namely, dendritic and lamellar forms) from the melt.

Modelling fuel combustion in iron ore sintering
Combustion and Flame, 2015Abstract In an iron ore sintering bed, the combustion behaviour of coke particles together with velocity of the flowing gas stream determines the temperature, width and speed of the traversing flame front. A bed heat treatment mathematical model was formulated in an earlier study to describe this complex relationship.

Dynamic process modelling of iron ore sintering
Steel Research, 1997A 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 various ...
