Iron Ore Sintering Process Model to Study Local ...

The iron ore sintering process prepares fine iron the ores for the blast furnace process. Sinter plants agglomerate iron ore fines with other fine materials at high temperature in a mix bed to create a product that can be used in a blast furnace. Main feed into a sinter plant is base mix, which consists of iron ore fines, coke fines and flux (lime stone) fines and iron bearing residues. The ...

What is a sintering process?

The purpose of the sinter plant is to process fine grained raw materials into a coarse grained iron ore sinter, ready to be charged to the blast furnace. Sintering of fine particles into a porous clinker – sinter – is necessary to improve the permeability of the burden, making reduction easier.

Phase Formation in Iron Ore Sintering

During the iron ore sintering process, iron ore fines (< 6 mm) are mixed with limestone flux and coke breeze and heated to ~1300ºC. This results in partial melting of the mixture, and converts the loose raw materials into a porous but physically strong composite material in which the iron bearing minerals are bonded together by a range of complex ferrite like phases known collectively by the ...

PROCESS BRIEF

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 is defined as the agglomeration of the Iron ore fines (generally <8 mm) by incipient fusion ...
