Theory and Practice of Sintering of Iron ore – IspatGuru

25/11/2018· Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (e.g. mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a particular form of agglomerate. It consists of heating the sinter mix with a particle size of less than 10 mm to,Sintering: A Step Between Mining Iron Ore and Steelmaking,11/06/2019· World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron.

Sinters are classified into acid sinter, self-fluxing sinter, and super fluxed sinter. Self-fluxing sinter has sufficient content of CaO (lime) in it which is required to flux its acid components (SiO2, and Al2O3).

CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

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 the blast furnace. TheThe Relationship Between Mining and Sintering,The sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace. The raw materials are sometimes mixed with water to provide a cohesive matrix, and then placed on a continuous, travelling grate called the sinter strand. A burner hood, at the,Sinter plant - Wikipedia,Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals.

Numerical Modeling of the Iron Ore Sintering Process

Iron ore sintering involves the movement of a flame front down a particulate bed, and a series of phys- ico-chemical reactions over a large temperature range. In the literature simple and more sophisticated iron ore sintering models have been reported. In this paper a more comprehensive numerical model which incorporates most of the significant processes and heat transfer modes proposed in,Chemical, Mineralogical and Metallurgical Characterization,,of sinter are: Particle Size Iron ore fines: The larger sized iron ore fines (> 10mm) does not take part in agglomeration rather is sometimes came un-sintered. The larger sized iron ore will segregate at a particular portion where sintering will be fast leaving behind the other portion. This situation will generate heterogeneous sinter chemistry.

SAFETY GUIDELINES FOR IRON & STEEL SECTOR MINISTRY OF,

Sintering process is developed mainly to utilize under size of lump ore called iron ore fines; which otherwise, could not be charged directly in blast furnace. In order to conserve these, otherwise waste material, they are compacted together and made into lumps by a process known as sintering.
