Iron Ore Sinter - an overview | ScienceDirect Topics
Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in East Asia. Granulation and thermal densification are two important steps in iron ore sintering and determine the quality of the resultant sinter and the performance of the sintering process.
Research on the reduction of iron ore in the …
Vor 2 Tagen · Iron ore sinter has been selected as raw material for reduction, but other iron-bearing mineral is also operable, such magnetite concentrate, pellet and so on. In the closed recycle system, CO 2 in vent gas was reduced by coke to produce coal oven gas with high calorific value. Next, the coal oven gas, serving as heating agent and reductant, was returned to the iron ore reduction process. 2 ...

Reduction of CO 2 Emissions by Use of Pre …
An iron ore sinter plant is a source of the second largest amount of CO 2 emissions next to a blast furnace at an integrated steel works. A technological development in the sintering process has improved an iron ore sinter quality such as strength and reducibility, which contributes to a decrease in a reducing agent rate of a blast furnace resulting in reduction of CO 2 emissions. There have ...

Iron Ore Sinter – IspatGuru
Iron ore sinter or simply called sinter is usually the major component of a blast furnace iron bearing burden material. Sinter normally consists of various mineral phases produced by sintering of iron ore fines with fluxes, metallurgical wastes and a solid fuel. Coke breeze is normally used as fuel in the sinter mix since it supplies necessary heat energy for sintering of sinter mix. Fig 1 shows a piece of sinter.
CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING
CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in productivity and saving in coke rate to …

Theory and Practice of Sintering of Iron ore – …
Sinter quality is dependent on the formation of the bonding phase which, in turn depends on the sintering ability of iron ore. On the other hand, the reactivity of iron ore is significantly influenced by its stone size which determines the reaction surface area and packing density (porosity) of the sinter mix. Hence, the particle size of the iron ore is important to control sintering reactions during the sintering …

Chemical state mapping of heterogeneous …
Iron ore sinter is composed of multiple iron oxide phases and calcium ferrites (CFs), and their heterogeneous reduction was investigated in terms of changes in iron stone state: Fe III, Fe II, and Fe 0 were examined macroscopically by 2D X-ray absorption and microscopically by 3D transmission X-ray microscopy (TXM). It was shown that the reduction starts at iron oxide grains rather than at ...
