The hydrogen reduction of iron ore sinters

Thermochimica Acta, 1986
Abstract 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, 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.

PCDD/F PROFILES OF AN IRON ORE SINTERING PLANT

2006
Dioxin 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, 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.

Formation and mitigation of PCDD/Fs in iron ore sintering

Chemosphere, 2011
The 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.

The Influence of Iron Ore Quality Degradation on the Assimilability of Sinter Ore

Advanced Materials Research, 2011
The sinter production is affected by many factors, including total iron content, gangue content and burning loss. These paper analyses changes of three kinds of Australian iron ores in recent ten years, and then draw a conclusion that the assimilability of these three kinds of Australian iron ores are increased.
