Effect of Concentrate and Micropellet Addition on Iron

Effect of Concentrate and Micropellet Addition on Iron

With the depletion of high-grade lump iron ore, concentrates have been identified as an alternative material for sinter making. Adding concentrates to the sinter mixture reduces sinter bed porosity and gas flow through the sinter bed. This will result in lower sinter strand productivity. A potential solution to this problem is to add concentrate in the form of micropellets.

Effect of concentrate and micropellet additions on iron

With the depletion of high-grade lump iron ore, concentrates have been identified as an alternative material for sinter making. In this study, the effect of concentrate and micropellet additions on the permeability of the sinter mixture was investigated. Permeability was measured on sinter mixtures containing 10–40% concentrate or micropellets at various moisture contents.

Iron Ore Sintering Process in Steel Thermo Fisher

Sinter is the primary feed material for making iron in a blast furnace. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200 C in a continuous belt-fed furnace.

The Relationship Between Mining and Sintering

The Relationship Between Mining and Sintering

Aug 15, 2019 The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is created by mixing iron ore concentrate with several additives such as limestone and silica to control the chemistry and then igniting it at 1200 C in a continuous belt-fed furnace.

Development of an iron ore microparticle binder for

In order to increase productivity and decrease reducing agent rate (RAR) of blast furnaces, slag content of sinter ore must be decreased. However, gangue content in iron ore tends to increase because of resource depletion. Therefore, amount of high-grade concentrate in sinter ore feeds should be increased, but this situation causes a decrease in permeability of the sintering bed so that the ...

Iron ore concentrate is produced from the magnetite iron ore in the beneficiation process and is used for the production of pellets for blast furnaces and sinter. The concentrates are non-toxic, non-flammable and non-explosive. The concentrate is shipped as a bulk commodity by rail using the open-top rolling stock and by sea.

CHAPTER 11 FUNDAMENTALS OF IRON ORE SINTERING

CHAPTER 11 FUNDAMENTALS OF IRON ORE SINTERING

While magnetite, fayalite and glass containing iron oxides are the major mineral phases for siliceous sinter, the ferrites, magnetite and mixed calcium iron silicates are the major mineral phases for fluxed sinter. Sintering is a fast process and it is unlikely that equilibrium will be reached during sintering.
