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.

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.

PCDD/F PROFILES OF AN IRON ORE SINTERING PLANT
2006Dioxin is formed as an unintentional by-product of many industrial processes involving chlorine, such as waste incineration, chemical and pesticide applications, pulp and paper bleaching, and sintering plants. At the moment, the iron sintering process is the principal PCDD/F source.

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.

Study on Sinter Iron Ores and Titanium Ores Used in Pelletizing
2021In this paper, study on sinter iron ores and titanium ores used in pelletizing was carried out. Bond work indexes of different sinter iron ores and titanium ores were measured. Ballability would be improved, and falling strength and compression strength of green pellets would be increased after fine-grinded sinter iron ores have been added.

The hydrogen reduction of iron ore sinters
Thermochimica Acta, 1986Abstract The hydrogen reduction of a series of sinters, produced from a Northamptonshire iron ore with various additions of coke, has been investigated over the temperature range 800°C to 1100°C using an electromagnetic balance. The reducibilities varied according to the carbon content of the original mix with high carbon sinters being less reducible

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.

Formation and mitigation of PCDD/Fs in iron ore sintering
Chemosphere, 2011The sintering of iron ore is presently a significant industrial source of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) worldwide owing to the fundamental requirement of the operation of a high temperature process to pre-treat fines and to recycle plant by-products arising from the integrated iron and steelworks.
