Iron Ore is the most important raw material needed to produce steel. However, it cannot be used directly in the blast furnace. That is why sinter is created that helps convert iron into steel. Rashmi Metaliks has its own Sinter Plant set up at 2007 to have complete control over the quality of materials used in the steel production process.

Metinvest offers a range of iron ore pellets for the blast furnace process, such as non-fluxed pellets produced by Central GOK with a basicity of 0.1. and 65.5% iron content, non-fluxed pellets ...

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

Pelletisation of iron ore involves the following four stages: 1. Raw Material Preparation: This step involves: Grinding of iron ore to required uniform size Concentration of iron ore and separation of unwanted gangue material Addition of binders, additives, etc. for preparation of agglomeration mixture 2.

Introduction to Iron ore Pellets and Pelletizing processes. Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh (0.074 mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter ...

12%The iron ore fines with less than 10 mm size are usually fed to the sintering process, and only limited fraction (less than 20%) of − 150 micron size of iron ore fines are allowed in the sintering process. The finer sized iron ore may choke the sinter bed and hinder the uniform air suction through the bed. As a result, sinter formation would ...

Iron ore fluxed sinter is the main ferrous burden of Jindal south west steel limited (JSWSL) blast furnaces. In sinter plant fluxes including limestone and dolomite are added to improve the sinter properties of iron ore and to provide an appropriate slag composition of the blast furnace.

Quadrilátero Ferrífero's iron ores used in the sintering process correspond to mixes of hematitic and goethitic ore typologies. The ores have particle size mainly distributed in the range from 6·35 to 0·105 mm. The goethitic typology comprises a low amount in these ore blends; however, it can be relevant in the reactivity during sintering.
