Magnetite And Sinter

19-02-2003· Domestic magnetite concentrates represent the dominant ore feed to most sinter plants in the PRC. Whilst increasing amounts of imported hematite ores are being added with magnetite concentrates into PRC sinter blends, little is known about the fundamental behaviour of magnetite concentrates during sintering compared to hematite ores.

Many sinter plants in China use magnetite concentrate and imported sintering fines in their blends. It has been found that sintering performance is improved with the addition of the sintering fines. This work studies sintering behaviour of a hematite ore (Ore B) and a geothite ore ...

The effects of magnetite concentrates properties including chemical compositions, particle size distribution and oxidisability were investigated and further discussed in association with the metallurgical properties of sinters and formation characteristics of liquid phase at high temperature zone in sinter bed.

Sinter Quality and Process of Sintering Iron Ores , The presence of MgO in the sinter improves the RDI, because MgO stabilizes magnetite and thus decreases the hematite content, causing a lower stress in the sinter during the hematite to , Inquiry; Mineralogy of Iron Ores of Different Alumina Levels from .

Magnetite concentrate is typically high in Fe grade and releases extra heat when oxidized to hematite. This will not only improve the sinter quality but also have a potential beneficial impact on ...

The de-gree of the improvements was found to be dependent on the level of imported sinter fines in the blends, and on sintering operations.1) Over the years, considerable fundamental research has been carried out to understand magnetite concentrate sinter-

On one hand, the presence of a small quantity (typically 10wt%) of magnetite concentrate can improve assimilation behaviour of ore mixture, promote sinter melt formation, and contribute to lower ...

Sinter made from magnetite concentrates (<10% hematite) relies on the formation of a network of fused magnetite–magnetite grains (diffusional bonding) and high temperatures (1350–1370 °C) to obtain satisfactory sinter tumble strength. Magnetite–hematite concentrate mixtures, with <45% hematite, behave during sintering like magnetite ...

use of magnetite for sinter production. Raw steel production increased to 866 million tons in 2018 from 816 million tons in 2017 But before all that iron ore can be turned into steel it must go through the sintering process Sinter is the primary feed material for making iron and steel in a blast furnace

Resulting in a lower yield and drum strength of vanadium-titanium sinter, the production volume of small size sinter also increases. Low-temperature reduction pulverization index (RDI −3.15) of the vanadium-titanium sinter is significantly higher than the sinter without vanadium-titanium magnetite [3, 4].

Oxida-tion of magnetite ores in the sintering process wasfound to be dependent on ore type, gangueminerals, oxygen pressure in atmosphereand temperature.3) For a mag-netite-hernatite blend, at sintering conditions, the ex-

The sintering basic characteristics of iron ore play a key role in the process of sintering. In this study, the effects of B 2 O 3 on the assimilation characteristics, softening temperature, fluidity of liquid phase, compressive strength of bonding phase, and microstructure of the mixed fine powder of hematite and vanadium-titanium magnetite (H-VTM) are studied.

Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption. During the iron ore sintering process in iron and steel manufacturing , an online analyzer can be used to determine the elemental composition of the bulk raw materials in sinter feed.

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.
