Mineralogical quantification of iron ore sinter

Mineral Processing and Extractive Metallurgy, 2016
The 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, 2015
Prediction 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

2020
Iron 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, 2002
Productivity 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.

Recent advances in iron ore sintering

Mineral Processing and Extractive Metallurgy, 2016
Sintering 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), 2007
Mineral 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, 2015
Abstract 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, 1997
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 various ...

Improved iron-ore sinter for blast furnaces

Steel in Translation, 2015
Technology has been developed for the production of fluxed local sinter and pellets with residual carbon for blast-furnace use. The new products have better metallurgical characteristics than existing materials.

Kinetics of iron ore sinter feed granulation

Powder Technology, 1990
Abstract The kinetics of iron ore sinter feed granalation were shown to have a major impact on granule size distribution. At laboratory scale, it was shown that granule growth continued until a maximum stable size distribution was achieved. Two stages to granule growth were observed.
